Allergic rhinitis (hay fever). It is unclear if oral astragalus is beneficial for allergic rhinitis. Details: Preliminary clinical research shows that taking a specific astragalus root extract standardized to contain 40% polysaccharides (Lectranal, Milsing d.o.o.) 160 mg orally twice daily for 3-6 weeks improves symptoms such as rhinorrhea, sneezing, and itching when compared with placebo in adults with seasonal allergic rhinitis (17355).
Amenorrhea. Oral astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One preliminary clinical study shows that taking a liquid decoction containing astragalus 30 grams, dong quai 30 grams, zizyphus 10 fruits, horny goat weed 15 grams, dodder 30 grams, and three slices of ginger, daily in two divided doses for 3 months, can increase menstrual frequency when compared to baseline in patients with amenorrhea (33050). The validity of this finding is limited by the lack of a comparator group. Additionally, it is unclear if this effect is due to astragalus, other ingredients, or the combination.
Angina. It is unclear if oral astragalus is beneficial for angina. Details: A preliminary clinical trial shows that taking astragalus 20 grams orally three times daily for 2 weeks can improve cardiac output, but not diastolic function, when compared to baseline in patients with angina (33063). The validity of these findings is limited by the lack of a comparator group.
Anthracycline cardiotoxicity. It is unclear if intravenous astragalus is beneficial for preventing cardiotoxicity due to anthracyclines. Oral astragalus has not been evaluated for this use. Details: A large unblinded clinical study in patients with breast cancer or lymphoma receiving a chemotherapy regimen containing epirubicin shows that intravenous use of astragalus 500 mg daily for 14 days during 2 courses of chemotherapy modestly attenuates the decline in left ventricular ejection fraction (LVEF) and reduces the occurrence of cardiotoxicity when compared with standard care (110479). However, this study was conducted in China, which limits the generalizability of its results.
Aplastic anemia. It is unclear if intravenous astragalus is beneficial for aplastic anemia. There is insufficient reliable information about the clinical effects of oral astragalus for this condition. Details: Preliminary clinical research in patients 15 years and older with chronic aplastic anemia shows that giving intravenous astragalus in combination with stanozolol 2 mg three times daily produces greater improvements in symptoms and blood cell counts than stanozolol alone. Astragalus was given as 80-120 grams daily for repeated 15-day courses at 7-10 day intervals for at least 4 months (32840).
Asthma. Oral astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in children with mild asthma shows that taking a combination of astragalus, cordyceps, Radix stemonae (Bai Bu), bulbus fritillariae cirrhosae, and Baikal skullcap orally for 6 months does not improve asthma symptoms, measures of lung function, or total steroid use when compared with placebo (32935).
Beta-thalassemia. Although there has been interest in using oral astragalus for beta-thalassemia, there is insufficient reliable information about the clinical effects of astragalus for this condition.
Breast cancer. Although there has been interest in using oral astragalus for breast cancer, there is insufficient reliable information about the clinical effects of astragalus for this condition.
Cervical cancer. Oral astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of 19 clinical trials in adults with cervical cancer who are receiving chemotherapy shows that the use of Chinese herbal medicines containing astragalus increases tumor response (complete and partial responses) and Karnofsky performance score and reduces chemotherapy-associated adverse effects when compared with chemotherapy alone (107479). However, most studies included in the meta-analysis were low-quality, and all studies were conducted in China. Higher quality studies in other geographic locations are needed to confirm these findings. Additionally, it is unclear if any effects are due to astragalus, other ingredients, or the combination.
Chemotherapy-induced anemia. Oral or intravenous astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of low-quality clinical trials in patients with colorectal cancer shows that oral or intravenous use of traditional Chinese medicine therapies containing astragalus and other ingredients along with conventional chemotherapy reduces the risk of anemia by 51% when compared with chemotherapy alone (102099). It is unclear if these effects are due to astragalus, the other ingredients, or the combination.
Chemotherapy-induced diarrhea. It is unclear if oral or intravenous astragalus is beneficial for chemotherapy-induced diarrhea. Details: One preliminary clinical study shows that intravenous infusion of astragalus 40 grams in 250 mL of solution, given daily for 21 days during each of four courses of chemotherapy, reduces diarrhea by 59% when compared to chemotherapy alone (32747). Additionally, a meta-analysis of low-quality clinical trials in patients with colorectal cancer shows that oral or intravenous use of traditional Chinese medicine therapies containing astragalus and other ingredients along with conventional chemotherapy reduces the risk of diarrhea by 45% when compared with chemotherapy alone (102099). It is unclear if these effects are due to astragalus, the other ingredients, or the combination.
Chemotherapy-induced leukopenia. Oral or intravenous astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of low-quality clinical trials in patients with colorectal cancer shows that oral or intravenous use of traditional Chinese medicine therapies containing astragalus and other ingredients along with conventional chemotherapy reduces the risk of thrombocytopenia by 41% when compared with chemotherapy alone (102099). It is unclear if these effects are due to astragalus, the other ingredients, or the combination.
Chemotherapy-induced nausea and vomiting (CINV). Early research suggests that intravenous astragalus seems to reduce nausea and vomiting associated with chemotherapy use. It is unclear if oral astragalus is beneficial for CINV. Details: A meta-analysis of low-quality clinical research in Chinese patients with advanced non-small cell lung cancer shows that intravenous infusion of astragalus along with platinum-based chemotherapy reduces the risk of vomiting by 38% when compared with platinum-based chemotherapy alone (100698). Another preliminary clinical study shows that intravenous infusion of astragalus 40 grams in 250 mL of solution, given daily for 21 days during each of four courses of chemotherapy, reduces nausea by 36% and vomiting by 50% when compared with chemotherapy alone (32747). Higher quality studies are needed to confirm these results. The use of astragalus in combination with other ingredients for prevention of CINV has also been investigated. A meta-analysis of low-quality clinical trials in patients with colorectal cancer shows that oral or intravenous use of traditional Chinese medicine therapies containing astragalus and other ingredients along with conventional chemotherapy reduces the risk of nausea and vomiting by 44% when compared with chemotherapy alone (102099). It is unclear if these effects are due to astragalus, the other ingredients, or the combination.
Chemotherapy-induced nephrotoxicity. Oral or intravenous astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of low-quality clinical trials in patients with colorectal cancer shows that oral or intravenous use of traditional Chinese medicine therapies containing astragalus and other ingredients along with conventional chemotherapy does not reduce the risk of nephrotoxicity when compared with chemotherapy alone (102099). The effects of astragalus when used alone are unclear.
Chemotherapy-related fatigue. It is unclear if intravenous astragalus is beneficial for chemotherapy-related fatigue. There is insufficient reliable information about the clinical effects of oral astragalus for this condition. Details: One clinical study in patients with advanced cancer shows that treatment with an intravenous infusion of a partially purified astragalus extract (PG2, Pharmagenesis), 500 mg three times weekly for 4 weeks during chemotherapy, improves fatigue scores after one week, but not after two and four weeks, when compared with placebo (33034).
Chronic fatigue syndrome (CFS). Oral astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One preliminary clinical study in adults with CFS shows that taking a 200 mL decoction containing astragalus 30 grams, kudzu 30 grams, codonopsis 15 grams, red sage 10 grams, aizoon stonecrop 15 grams, horny goat weed 10 grams, turmeric 10 grams, and calamus 10 grams, in two divided doses daily for 3 months improves fatigue symptoms when compared to baseline (32920). Another preliminary clinical study shows that taking 1.5 grams of a specific product (Myelophil, Samik Pharmaceutical Company) containing 66% of extracts of astragalus and danshen in a 1:1 ratio twice daily for 4 weeks improves fatigue severity when compared with placebo. However, taking 3 grams of the same product twice daily does not seem to have a benefit (32883). It is unclear if these effects are due to astragalus, the other ingredients, or the combination.
Chronic kidney disease (CKD). It is unclear if intravenous astragalus is beneficial for CKD. There is insufficient reliable information about the clinical effects of oral astragalus for this condition. Details: A meta-analysis of preliminary clinical research in patients with CKD shows that using astragalus, usually as an injection, along with conventional treatment modestly improves creatinine clearance by 6 mL/min, serum creatinine by 0.25 mg/dL, and hemoglobin levels by 1 gram/dL when compared with conventional treatment alone (90660). However, the studies included in the meta-analysis were of low quality. Additionally, a moderate-sized clinical study in patients with CKD and type 2 diabetes shows that taking astragalus 15 grams daily for 5 days per week in combination with standard care for 48 weeks ameliorates the decline in glomerular filtration rate, but does not improve the urinary albumin to creatinine ratio, when compared with standard care alone (114803). The validity of these findings is limited by methodological flaws, including inadequate blinding. Also, it is not known if astragalus reduces mortality or attenuates the progression to kidney failure.
Chronic obstructive pulmonary disease (COPD). Intravenous astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of low-quality clinical studies in adults with COPD shows that intravenous astragalus 10-60 mL (concentration not specified) once or twice daily for 2 weeks in combination with ambroxol hydrochloride and other conventional therapies improves COPD clinical symptoms, some measures of pulmonary function, and arterial blood gases when compared with conventional therapies alone (114688). All studies were conducted in China which may limit generalizability of the results. It is unclear if these effects are due to astragalus, ambroxol hydrochloride, or the combination.
Cirrhosis. Intravenous astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. There is insufficient reliable information about the clinical effects of oral astragalus for this condition. Details: A meta-analysis of results from low-quality clinical studies shows that intravenous injection of a combination of astragalus and danshen for up to 90 days might decrease fibrosis when compared with control in patients with liver cirrhosis (90662). However, it is unclear if this is due to astragalus, danshen, or the combination.
Colorectal cancer. Oral or intravenous astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of clinical trials in patients with colorectal cancer shows that oral or intravenous use of traditional Chinese medicine therapies containing astragalus and other ingredients along with conventional chemotherapy improves quality of life scores and increases the rate of tumor response by 52% when compared with chemotherapy alone (102099). It is unclear if these effects are due to astragalus, the other ingredients, or the combination.
Diabetes. It is unclear if oral or intravenous astragalus is beneficial for diabetes. Details: A meta-analysis of preliminary clinical research in Chinese patients with type 2 diabetes shows that astragalus, given as a daily intravenous injection 40-80 grams or taken orally 40-60 grams daily as an aqueous decoction for up to 4 months, modestly improves fasting and postprandial blood glucose levels when compared to a control group. Oral astragalus seems to improve these outcomes slightly more than intravenous astragalus. Orally, astragalus also seems to improve fasting insulin levels and insulin resistance, although its effect on glycated hemoglobin (HbA1c) is inconsistent. (95909). Astragalus has also been evaluated as an adjuvant therapy to metformin. A meta-analysis of several mostly small clinical studies in adults with type 2 diabetes shows that taking astragalus 10-50 grams daily with metformin modestly reduces fasting blood glucose by approximately 12 mg/dL, 2-hour postprandial blood glucose by 12 mg/dL, and HbA1c by 0.9% when compared with metformin monotherapy (112809). A meta-analysis of mostly low-quality clinical studies in patients with diabetes shows that taking astragalus in the form of traditional Chinese medicine, with or without Western medicine, reduces fasting blood glucose, 2-hour postprandial glucose, and glycated hemoglobin when compared with Western medicine alone (114805). However, the clinical studies included in both of these meta-analyses are of low methodological quality and include only Chinese patients, which limits the reliability and generalizability of the results. Some research has evaluated astragalus in combination with other ingredients. One preliminary clinical study in adults with previously untreated type 2 diabetes shows that taking astragalus 210 mg, goldthread 350 mg, and honeysuckle 840 mg three times daily before meals for 3 months does not improve fasting blood glucose, postprandial blood glucose, or HbA1c when compared with placebo, although glucose disposal rate is modestly improved (32925).
Diabetic nephropathy. It is unclear if intravenous astragalus is beneficial for diabetic nephropathy. Details: Meta-analyses of small, low-quality clinical studies including over 4700 patients shows that adding intravenous astragalus to routine therapy for 2-12 weeks modestly improves blood urea nitrogen, serum creatinine, creatinine clearance, urinary protein, urinary albumin, and serum albumin when compared with routine therapy alone in patients with diabetic nephropathy (33019,102100).
Diabetic neuropathy. It is unclear if oral astragalus is beneficial for diabetic neuropathy. Details: A meta-analysis of mostly low-quality clinical studies in patients with diabetic neuropathy shows that taking astragalus in the form of traditional Chinese medicine, with or without Western medicine, modestly reduces signs and symptoms of diabetic neuropathy when compared with Western medicine alone (114805). However, this improvement may not be clinically significant. Additionally, all studies were conducted in China which may limit generalizability of the results.
Diabetic retinopathy. It is unclear if oral astragalus is beneficial for diabetic retinopathy. Details: A meta-analysis of results from preliminary clinical research suggests that taking astragalus-containing products for up to 10 months modestly improves visual acuity and fundus manifestations when compared with control in patients with diabetic retinopathy. However, the included studies had methodological limitations, and the results were heterogeneous (90655).
Fibromyalgia. Although there has been interest in using oral astragalus for fibromyalgia, there is insufficient reliable information about the clinical effects of astragalus for this condition.
Gastric cancer. Oral and intravenous astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of 35 randomized, controlled trials involving 2670 patients with advanced gastric cancer shows that taking either intravenous or oral traditional Chinese medicines containing astragalus in conjunction with platinum-based chemotherapy may improve objective response rate, disease control rate, 1-year survival rate, and quality of life, and may also reduce the severity of chemotherapy-associated adverse effects, when compared with chemotherapy alone (107480). The validity of this meta-analysis is limited by potential publication bias, unclear randomization methods, and substantial heterogeneity among the included studies. Additionally, it is unclear if these effects are due to astragalus, other ingredients, or the combination.
Hearing loss. It is unclear if intravenous astragalus is beneficial for hearing loss. Details: Preliminary clinical research shows that injecting 0.5 mL/kg of solution containing astragalus 2 grams/mL daily for 10 days improves hearing in people with sudden deafness or acute acoustic trauma when compared with a control group (33028,33033).
Heart failure. It is unclear if oral or intravenous astragalus is beneficial for heart failure. Details: A meta-analysis of small to moderate-sized low quality clinical studies in adults with heart failure with reduced ejection fraction (HFrEF) shows that oral astragalus 30 grams twice daily or intravenous astragalus 20-60 mL (concentration not specified) daily for 2-4 weeks combined with conventional treatment modestly increases left ventricular ejection fraction (LVEF), decreases brain natriuretic peptide levels, and increases 6-minute walking distance when compared with conventional treatment alone (114804). Findings are limited by significant heterogeneity. Additionally, all studies were conducted in China which may limit generalizability of the results. The conflicting nature of these results are reflected in other small studies. One preliminary clinical study in adults with CHF shows that intravenous infusion of astragalus 60 grams daily for 20 days improves LVEF and left ventricular end-diastolic volume (LVEDV) when compared with conventional treatment (32755). However, another preliminary clinical study shows that intravenous astragalus 60 grams daily for 28 days in combination with conventional treatment for CHF does not improve LVEF, LVEDV, or left ventricular end-systolic volume when compared with conventional treatment alone (32812). Other preliminary clinical research shows that taking oral astragalus 2.25-7.5 grams twice daily for 14-30 days in combination with conventional treatment improves cardiac function, LVEF, and walking distance when compared with conventional treatment alone (33018,33022). However, each of these studies has methodological problems.
Hepatitis B. Although there has been interest in using oral astragalus for hepatitis B, there is insufficient reliable information about the clinical effects of astragalus for this condition.
HIV/AIDS. Oral astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study shows that taking a combination containing mainly Baikal skullcap root, glossy privet fruit, astragalus root, and Eupolyphaga et polyphage (Ailing granules) 20 grams twice daily for 4 months improves HIV/AIDS symptoms and CD4 cell counts (32824). However, taking a different combination containing licorice, yin chen, white mulberry, astragalus, and safflower orally for 12 weeks is associated with only a slight decline in viral load and no change in CD4 cell counts (32795). The effects of astragalus alone are unclear.
IgA nephropathy. Although there has been interest in using intravenous astragalus for IgA nephropathy, there is insufficient reliable information about the clinical effects of oral or intravenous astragalus for this condition.
Lung cancer. Early research suggests that oral or intravenous astragalus seems to increase the effectiveness of platinum-based chemotherapy or radiotherapy in patients with advanced non-small cell lung cancer (NSCLC). Details: One meta-analysis in patients with advanced NSCLC shows that intravenous administration of astragalus along with platinum-based chemotherapy increases the rate of one-year survival by 40% when compared with platinum-based chemotherapy alone (100698). Other meta-analyses in these patients show that use of oral or intravenous astragalus-containing herbal products appears to reduce the risk of death at six months by 42%, at one year by 33%, at two years by 27% to 33%, and at three years by 15% to 24% when compared with platinum-based chemotherapy or radiotherapy alone (15001,90656). Additionally, a network meta-analysis of clinical research in patients with NSCLC ranks intravenous administration of astragalus along with a combination of docetaxel and cisplatin as the most effective of various Chinese herbal medicine injection and docetaxel and cisplatin combinations (114689). However, most studies included in the meta-analyses were low-quality, and all studies were conducted in China. Higher quality studies in other geographic locations are needed to confirm these findings.
Membranous nephropathy. Oral astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of 48 small, low-quality clinical studies in adults with idiopathic membranous nephropathy conducted in China shows that taking astragalus 20-90 grams per day in combination with a variety of other supplements, in addition to conventional therapy, modestly improves the rate of complete or partial renal remission when compared with conventional therapy (e.g. angiotensin-converting enzyme inhibitors, immunosuppression). Adding astragalus combinations to conventional therapy also modestly reduces proteinuria and serum creatinine (112010). However, the interpretation of these findings is limited by the heterogeneity of the included studies and variable definitions of complete and partial renal remission. Additionally, it is unclear if these effects are due to astragalus, other ingredients, or the combination.
Menopausal symptoms. Oral astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One preliminary clinical study shows that taking Dang Gui Buxue Tang, an herbal decoction containing astragalus and dong quai extract, 3 grams daily for 6 months does not reduce the incidence of menopausal hot flashes (32857). However, another preliminary clinical study shows that taking Dang Gui Buxue Tang 3-6 grams daily for 12 weeks reduces hot flash frequency by up to 40% and night sweat frequency up to 53% when compared to baseline (90659). Each 1.5 grams of Dang gui Buxue Tang contains extract prepared from dong quai 1.5 grams and astragalus 7.5 grams (90659). Another small clinical study in females with moderate or severe menopausal symptoms shows that taking a tablet containing astragalus and Rubus coreanus extract 1000 mg twice daily for 12 weeks modestly improves symptom and quality of life scores when compared with placebo (110478). However, the validity of these findings is limited by a high rate of study participant discontinuation.
Myocardial infarction (MI). Although there has been interest in using intravenous astragalus for MI, there is insufficient reliable information about the clinical effects of oral or intravenous astragalus for this purpose.
Myocarditis. It is unclear if oral or injectable astragalus is beneficial for viral myocarditis. Details: A meta-analysis of 13 mostly small, low-quality clinical studies in adults and children with viral myocarditis shows that astragalus injection may improve the total effective rate and reduce markers of inflammation when compared with conventional treatment (110477). However, most studies included in the meta-analysis were low-quality, dosing was variable, and all studies were conducted in China. Higher quality studies in other geographic locations are needed to confirm these findings. Several clinical studies report improvements in cardiac enzymes, cardiac function, or viral load in peripheral leukocytes with the use of astragalus preparations, but results are inconsistent and the methodological quality of these studies is low (33084,33105,33217,33218,33220,33221,33223). Doses demonstrating benefit include intramuscular astragalus extract, equivalent to 8 grams daily for 3-4 months (33105) and intravenous astragalus extract 40 grams daily for 2 weeks (33218,33221). It is unclear if astragalus speeds recovery or reduces the risk of mortality due to myocarditis.
Nephrotic syndrome. It is unclear if oral astragalus is beneficial for preventing infections in patients with nephrotic syndrome. Details: A meta-analysis of results from two preliminary clinical studies shows that taking astragalus 7.5-15 grams twice daily for 3-6 months reduces the risk of infection by 38% when compared to control in children with nephrotic syndrome (33036).
Obesity. Oral astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a combination of astragalus, rhubarb, turmeric, red sage root, ginger, and gallic acid concurrently with a reduced-calorie diet does not improve weight loss when compared with a reduced-calorie diet alone in adults who are overweight or obese (20347).
Post-stroke fatigue. It is unclear if oral astragalus is beneficial for post-stroke fatigue. Details: A preliminary clinical study shows that taking astragalus extract (Sun Ten Pharmaceutical Co. Ltd.) 2.8 grams three times daily for 28 days improves fatigue and some quality of life measures such as social functioning, role functioning, and physical functioning, when compared with placebo in patients experiencing fatigue following a recent stroke (95908).
Systemic lupus erythematosus (SLE). It is unclear if intravenous astragalus is beneficial for lupus nephritis. There is insufficient reliable information about the clinical effects of oral astragalus for this condition. Details: A preliminary clinical study in adults with lupus nephritis shows that intravenous infusions of astragalus 40 grams daily for 12 consecutive days monthly for 3 months, in combination with corticosteroids and cyclophosphamide once monthly as an intravenous drip, can improve symptoms, reduce infections, and reduce urinary protein excretion when compared to treatment with corticosteroids and cyclophosphamide alone (32838).
Tinnitus. It is unclear if intravenous astragalus is beneficial for tinnitus. Details: Preliminary clinical research shows that injecting 0.5 mL/kg of solution containing astragalus 2 grams/mL daily for 10 days reduces tinnitus in patients with acute acoustic trauma when compared to a control group (33028).
Upper respiratory tract infection (URTI). Although there has been interest in using oral astragalus for URTI prevention, there is insufficient reliable information about the clinical effects of astragalus for this purpose.
Urinary Tract Infections (UTIs). Oral astragalus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-size clinical study in females aged 18-45 with uncomplicated UTIs shows that taking a supplement containing astragalus root extract 100 mg, d-mannose, citric acid, dandelion, and prebiotics as a sachet dissolved in water twice daily for 5 days improves complete resolution of UTI symptoms and clearance of bacteriuria at days 6 and 35 when compared with placebo (111757). However, it is unclear if these effects are due to astragalus, other ingredients, or the combination.
Wound healing. Although there has been interest in using topical astragalus for wound healing, there is insufficient reliable information about the clinical effects of astragalus for this purpose. More evidence is needed to rate astragalus for these uses.

POSSIBLY EFFECTIVE

Cognitive function. In middle-aged individuals, but not young adults, oral Panax ginseng seems to improve abstract thinking, attention, arithmetic skills, and reaction time. Any benefit to memory seems to be dependent on the inclusion of ginkgo. Details: Some clinical evidence shows that taking Panax ginseng orally can improve abstract thinking, attention, mental arithmetic skills, and reaction times in healthy, middle-aged people; however, Panax ginseng does not seem to improve these outcomes in young adults (2064,23596,23599,23608,23609,54374). While Panax ginseng alone does not seem to improve memory (2064), there is some evidence that a combination of Panax ginseng (G115) and ginkgo leaf (GK501) extract 80-320 mg daily for 12 weeks can improve memory in otherwise healthy people or people with neurasthenia 38-66 years of age (8591,9759,87984,88046). In clinical trials, various doses have been used. These include a specific Panax ginseng extract (G115, Pharmaton SA, Lugano) 200-400 mg once daily or in two divided doses for up to 12 weeks, or 200-960 mg administered as a single dose (8591,23596,23599,23608,23609,54374,88046). Another extract (Gerimax Ginseng Extract; Dansk Droge A/S Ishoj) 400 mg daily for 8 weeks has also been used (2064).
Erectile dysfunction (ED). Oral Panax ginseng seems to improve sexual function in people with ED. Details: Taking Panax ginseng orally for 8 weeks seems to improve sexual function in adults with ED (8813,23637,23638,89747). Doses used in clinical research have included extract from the juice and pulp of 4 year-old Panax ginseng berry 700 mg twice daily (89747), tissue-cultured mountain ginseng extract 1000 mg twice daily (23638), and Korean red ginseng, a type of Panax ginseng, 1000-2700 mg daily (8813,112840). Panax ginseng has also been studied in adults with symptoms of ED that are associated with an enlarged prostate. A small clinical study in adult males with moderate lower urinary tract symptoms shows that taking a specific extract of Korean red ginseng (RXGIN, Jung Kwan Jang), a type of Panax ginseng, 1000 mg daily for 12 weeks improves symptoms of sexual dysfunction including erectile function, sexual desire, orgasmic function, and intercourse satisfaction when compared with placebo. However, there was no improvement reported in overall satisfaction. Most symptoms of ED except sexual desire had not significantly improved by 6 weeks, suggesting that longer durations of at least 12 weeks may be needed for Panax ginseng to significantly improve ED symptoms (112840). Additionally, Panax ginseng has been evaluated in combination with other ingredients. A moderate-sized, open-label clinical study in adults with mild-to-moderate ED shows that taking a specific combination supplement (Icarifil, Anvest Health S.p.A) containing Panax ginseng 150 mg, L-carnitine, L-citrulline, tribulus, and other ingredients daily for 3 months improves patient-reported erectile function when compared to baseline. Additionally, taking the supplement with tadalafil improves some, but not all, patient-reported assessments of erectile function when compared with taking tadalafil alone (114989). It is unclear if this effect is due to Panax ginseng, other ingredients, or the combination. Additionally, the interpretation of these results is limited by poor methodology, including the use of per-protocol analysis and lack of a placebo group.
Influenza. Oral Panax ginseng seems to modestly reduce the risk of developing influenza. However, it might not reduce the severity or duration of symptoms. Details: Some preliminary clinical research shows that taking a specific Panax ginseng extract (G115) 200 mg daily, beginning 4 weeks prior to influenza vaccination and continuing for 8 weeks thereafter, can decrease the relative risk of getting the flu or common cold by 65% when compared with placebo (589). Also, clinical research in healthy adults shows that taking Panax ginseng extract 1 gram three times daily for 12 weeks reduces the relative risk of developing an acute influenza infection by 45% when compared with placebo. However, taking Panax ginseng does not seem to affect symptom duration or severity (89746).
Multiple sclerosis-related fatigue. Oral Panax ginseng seems to reduce fatigue and improve quality of life in patients with multiple sclerosis. Details: Clinical research shows that taking Panax ginseng 250 mg twice daily for 3 months improves symptoms of fatigue and quality of life when compared with placebo in female patients with relapsing-remitting multiple sclerosis (RRMS). Females taking Panax ginseng experienced a 75% reduction in fatigue, compared with no change in the placebo group; quality of life was increased by 19.9 points in the Panax ginseng group, compared with only 4.2 in the placebo group (89745).
Sexual arousal. Oral Panax ginseng, alone or in combination with other ingredients, seems to improve sexual arousal in postmenopausal adults or females with sexual dysfunction. Details: Taking Korean red ginseng, a specific form of Panax ginseng, 3 grams daily for 8 weeks seems to improve sexual arousal and satisfaction when compared with placebo in postmenopausal adults (23630). Also, other preliminary clinical research shows that taking a specific combination product (ArginMax for Women, Daily Wellness Company) containing ginkgo leaf extract, Panax ginseng root extract, damiana leaf extract, L-arginine, multivitamins, and minerals for 4 weeks can improve sexual satisfaction when compared with placebo in females who are self-reported to have sexual dysfunction (23635,46933). It is unclear if this effect is due to Panax ginseng, other ingredients, or the combination.

POSSIBLY INEFFECTIVE

Athletic performance. Most research shows that oral Panax ginseng does not improve athletic performance. Details: Taking Panax ginseng 0.4 to 3 grams daily orally for up to 8 weeks, or as a single dose 200 mg one hour prior to exercise, does not improve aerobic exercise capacity (1427,4230,4231,23646,23647,89737,114981). Higher doses of Panax ginseng also do not seem to improve athletic performance. A small study in young athletes shows that taking Panax ginseng 100 mg/kg (about 5-7 grams, standardized to 10% ginsenosides) daily in three divided doses for 8 days does not improve squat exercise performance, although it might modestly improve perceived exertion, when compared with placebo (103045). Similarly, a small clinical study in adult male recreational athletes shows that taking Panax ginseng extract 500 mg daily for 14 days does not improve 10-kilometer running times when compared with placebo (114981).

Aging. Although there has been interest in using oral Panax ginseng for aging, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Anthracycline cardiotoxicity. It is unclear if oral Panax ginseng protects against anthracycline cardiotoxicity. Details: A very small clinical study in adults with non-metastatic HER-2 negative breast cancer being treated with anthracycline-based chemotherapy in Iran shows that taking Panax ginseng rhizome powder 1000 mg daily starting on the first day of doxorubicin administration until one week after completion of the eighth doxorubicin cycle improves left ventricular ejection fraction (LVEF) by 1% when compared with placebo, which was associated with a 7% reduction in LVEF. Treatment with Panax ginseng also reduces the incidence of chemotherapy-related cardiac dysfunction when compared with placebo, an effect that endured over a 6-month follow up period. However, Panax ginseng did not improve the cardiac biomarker high-sensitive cardiac troponin I or transthoracic echocardiographic measurements of left atrium diameter, left ventricular end-systolic diameter, or left ventricular end-diastolic diameter when compared with placebo (112817).
Attention deficit-hyperactivity disorder (ADHD). Oral Panax ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small low-quality study in children with ADHD aged 6-12 years shows that taking Panax ginseng extract 3 mg with omega-3 fatty acids 500 mg daily for 12 weeks improves overall symptoms, reduces errors of commission, and improves reaction time when compared with baseline (103049). The validity of this study was limited by the lack of a comparator group. Also, it is unclear if these changes are due to Panax ginseng, omega-3 fatty acids, or the combination.
Age-related cognitive decline. It is unclear if oral Panax ginseng is beneficial in age-related cognitive decline. Details: Clinical research in patients over 50 years of age with memory impairments shows that taking standardized ginseng extract (G115) in combination with vitamins, minerals, and dimethylaminoethanol bitartrate may improve memory when compared to baseline (23600). The validity of this finding is limited by the lack of a comparator group. Also, it is unclear if these changes are due to Panax ginseng, other ingredients, or the combination.
Allergic rhinitis (hay fever). It is unclear if oral Panax ginseng is beneficial in allergic rhinitis. Details: A small clinical study in adults with allergic rhinitis shows that taking Panax ginseng (Korean Ginseng Corporation) 3 mg/kg daily for 4 weeks improves rhinorrhea, nasal itch, and eye itch when compared to baseline (103047). The validity of this study is limited because it did not report statistical comparisons between the treatment and control groups.
Alzheimer disease. Some preliminary clinical studies suggest that oral Panax ginseng might improve cognitive performance in patients with this condition. Details: Clinical research shows that taking Panax ginseng root 4.5 to 9 grams daily for 12 weeks can improve cognitive performance in patients with Alzheimer disease when compared with control (23611,23612). The validity of this finding is limited by the lack of patient and caregiver blinding.
Androgenic alopecia. Topical Panax ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with androgenic alopecia shows that applying 1 mL of a topical combination product (Hirsuit hair tonic, Dermcor Pharmaceutical) containing Panax ginseng extract, biochanin A (from red clover), acetyl tetrapeptide-3, Salvia officinalis oil, and other ingredients, twice daily for 24 weeks, is similarly effective to minoxidil 3% solution for increasing hair count and mass (105672). It is unclear if the benefit is due to Panax ginseng, other ingredients, or the combination.
Anxiety. Although there has been interest in using oral Panax ginseng for anxiety, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Aplastic anemia. Although there has been interest in using oral Panax ginseng for aplastic anemia, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Asthma. Although there has been interest in using oral Panax ginseng for asthma, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Benign prostatic hyperplasia (BPH). It is unclear if oral Panax ginseng is beneficial for treating lower urinary tract symptoms. Details: A small clinical study in adults with moderate lower urinary tract symptoms shows that taking a specific extract of Korean red ginseng (RXGIN, Jung Kwan Jang), a type of Panax ginseng, 1000 mg daily for 12 weeks reduces serum prostate-specific antigen (PSA) and improves most prostate symptoms including residual urine sensation, frequency, intermittency, urgency, weak stream, straining, and nocturia after 6 and 12 weeks when compared with placebo. However, there was no improvement in maximum urinary flow rate or post-void residual volume when compared with placebo (112840).
Breast cancer. It is unclear if oral Panax ginseng is beneficial in breast cancer. Details: Observational research in Chinese patients with breast cancer suggests that regular use of ginseng, including either Panax ginseng or American ginseng, is associated with higher quality of life scores and a lower risk of overall mortality, breast cancer-related mortality, and breast cancer recurrence when compared with patients who do not take ginseng (14466). However, ginseng users were also significantly more likely to have been treated with tamoxifen. Another small clinical study in adults with non-metastatic breast cancer undergoing anthracycline-based chemotherapy in Iran shows that taking Panax ginseng 1 gram daily starting on the first day of chemotherapy until 1 week after completion of the final cycle at 7 or 10 weeks improves social, emotional, and functional measures of health-related quality of life but does not improve physical well-being when compared with placebo (112823).
Bronchitis. It is unclear if oral Panax ginseng is beneficial in bronchitis. Details: One small clinical study shows that taking a specific Panax ginseng extract (G115) 100 mg twice daily for 9 days might be beneficial when used adjunctively for treating acute exacerbations of chronic bronchitis. Panax ginseng, combined with antibiotic therapy, might reduce bronchial bacterial counts more than antibiotic therapy alone (8814).
Cancer. It is unclear if oral Panax ginseng is beneficial in preventing cancer. However, it might increase quality of life in some cancer patients. Details: Observational research has found that taking ginseng orally might decrease the incidence of cancer, specifically breast, stomach, lung, liver, ovarian, and skin cancer (2063,3122). But evidence from large-scale clinical research shows that taking Panax ginseng 1 gram once weekly for 3 years does not reduce the risk of cancer development (23622). However, some clinical research suggests that Panax ginseng may slow cancer progression or improve quality of life in patients already diagnosed with cancer. One clinical study shows that taking sun ginseng, a form of Panax ginseng that has been heat treated, 3000 mg daily orally for 12 weeks can improve quality of life for cancer patients (23643). Evidence from a case series suggests that giving Panax ginseng (also called Cultivated Wild Ginseng Pharmacopuncture) 20 mL daily by intravenous infusion for up to 13 cycles lasting 2-4 weeks each may attenuate the progression of advanced non-small cell lung cancer in some patients (23619,23620).
Cancer-related fatigue. It is unclear if oral Panax ginseng is beneficial in cancer-related fatigue. Details: Preliminary clinical research shows that taking Panax ginseng 400 mg twice daily for 4 weeks reduces fatigue in 63% of adults with cancer-related fatigue when compared to baseline. Panax ginseng also reduces pain and improves appetite and overall quality of life when compared to baseline. The lack of a control group limits the validity of these findings (96217). Another clinical study in patients with colorectal cancer receiving the mFOLFOX-6 chemotherapy regimen shows that taking Panax ginseng 2000 mg daily for 16 weeks improves fatigue as measured on the brief fatigue inventory (BFI) when compared with placebo. However, when evaluated on the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue scale, no benefit was seen (103048).
Chronic fatigue syndrome (CFS). It is unclear if oral Panax ginseng is beneficial in patients with severe CFS. Details: A nonblinded, observational study in patients with severe CFS, most of whom also have fibromyalgia, shows that taking Panax ginseng daily for one month improves patient reports of energy, overall wellbeing, mental clarity, sleep, pain, and stamina when compared with baseline. Patients took Panax ginseng either as capsules (Terry Naturally HRG80 Red Ginseng Energy capsules; EuroPharma, Inc) 200-400 mg daily or chewable tablets (Terry Naturally HRG80 Red Ginseng Energy chewable tablets; EuroPharma, Inc) 100-200 mg daily. There were no dose- or formulation-dependent differences between groups (107746). The validity of these findings is limited by the lack of randomization and placebo-control; additionally, the majority (89%) of patients included in this study were female.
Chronic kidney disease (CKD). It is unclear if oral Panax ginseng prevents CKD. Details: A cross-sectional study in Korea suggests that supplemental Panax ginseng or American ginseng use is associated with a higher prevalence of CKD when compared with no supplemental ginseng use. However, no association was found when adjusting the results for potential confounders (112810). The applicability of these results is limited by a lack of subgroup analysis on the type of supplemental ginseng.
Cognitive impairment. It is unclear if oral Panax ginseng is beneficial for the prevention or treatment of cognitive impairment. Most research has evaluated Panax ginseng in combination with other ingredients. Details: Preliminary clinical research in elderly patients with mild cognitive impairment shows that taking a specific combination product (Memo, Pharco Pharmaceuticals), which contains natural lyophilized royal jelly 750 mg, standardized ginkgo leaf extract 120 mg, and standardized Panax ginseng root extract 150 mg, orally for 4 weeks improves memory when compared with placebo (89712). It is unclear if these benefits are due to Panax ginseng, other ingredients, or the combination. A moderate-sized clinical study in older adults with subjective memory impairment shows that taking a specific Panax ginseng sprout extract (ThinkGIN, BTC Corporation) 450 mg daily for 12 weeks improves performance on some verbal and visual memory tests and cognitive function as measured with MoCA-Korean version when compared with placebo (114983).
Common cold. It is unclear if oral Panax ginseng is beneficial in preventing the common cold. Details: Preliminary clinical research shows that taking a specific Panax ginseng extract (G115) 200 mg daily orally beginning 4 weeks prior to influenza vaccination and continuing for 8 weeks thereafter can decrease the relative risk of getting the flu or common cold by 65% when compared with placebo (589).
Congestive heart failure (CHF). It is unclear if oral Panax ginseng is beneficial in CHF. Details: A small clinical study in adults with CHF shows that Panax ginseng 2 grams daily, with or without digoxin 0.25 mg once daily for 15 days, seems to improve heart function according to New York Heart Association (NYHA) classification when compared to baseline. Ginseng might also improve hemodynamics and may work synergistically with digoxin (4243). The validity of these findings is limited by the lack of a comparator group.
Constipation. It is unclear if oral fermented Panax ginseng is beneficial for constipation. Details: An observational study in healthy postmenopausal adults aged 50 years and older in Korea suggests that taking fermented red ginseng 20 mL before meals daily for 3 weeks normalizes stool consistency and increases the frequency of bowel movements when compared to baseline (112837). The validity of these effects is limited by the observational study design, lack of a comparator group, and insufficient blinding.
Chronic obstructive pulmonary disease (COPD). Oral Panax ginseng has primarily been evaluated in combination with other ingredients for improving symptoms of COPD; its effect when used alone is unclear. Taking Panax ginseng doesn't seem to prevent exacerbations. Details: A meta-analysis of clinical trials in patients with stable COPD shows that taking Panax ginseng, usually in combination with other ingredients as part of TCM formulations, significantly improves pulmonary function tests and quality of life when compared with placebo after 3-6 months of treatment. These formulations improve COPD symptoms by approximately 53% when compared with placebo. However, they only modestly improve forced expiratory volume in one second (FEV1) (17736). In contrast, Panax ginseng might not reduce the risk of COPD exacerbations. A clinical study in patients with moderate to very severe COPD shows that taking Panax ginseng 200 mg does not reduce the rate of acute COPD exacerbations over 12 months (103044).
Depression. It is unclear if Panax ginseng is beneficial in depression. Details: In adults with treatment-resistant major depressive disorder, a small clinical study shows that taking Panax ginseng 2 grams daily in addition to current antidepressant medications for 6 weeks produces remission in 39% of patients and decreases scores on the Montgomery-Asberg Depression Rating Scale by a mean of 44% when compared with baseline (104954). The reliability of these findings is limited by the lack of a control group, randomization, blinding, and an intention-to-treat analysis, as well as a high drop-out rate.
Diabetes. Research on the use of oral Panax ginseng for improving glycemic control in patients with diabetes is inconclusive and conflicting. Details: A meta-analysis of 6 small clinical trials in patients with type 2 diabetes using Panax ginseng for 4-24 weeks and 3 small trials using American or unidentified ginseng for 4-8 weeks, shows that taking these ingredients modestly reduces fasting blood glucose, but does not affect glycated hemoglobin (HbA1c) or insulin levels, when compared with control (105689). This analysis is limited by publication bias, as well as the heterogeneity and imprecision of the included trials. Another meta-analysis of 5 clinical studies in healthy adults and adults with a variety of metabolic disorders including diabetes and prediabetes shows that taking Panax ginseng 200 mg up to 8 grams daily for 4 to 24 weeks does not improve fasting blood glucose, 2-hour postprandial blood glucose, HbA1c, or insulin levels when compared with placebo. However, Panax ginseng might improve glucose AUC in these individuals. Subgroup analysis further suggests that the beneficial effect of Panax ginseng on glucose AUC is greater in adults with diabetes than those with prediabetes (112838). Individual small studies have shown modest glycemic benefit with fermented Panax ginseng 2.7 grams daily for 4 weeks or non-fermented Panax ginseng 6 grams daily for 8-12 weeks (23627,89740), and other studies have shown no benefit with Korean red ginseng extract or Korean black ginseng 2-8 grams daily for 4-6 weeks (17734,112839). It is unclear if the effects of Panax ginseng may be dose- or product-dependent. Panax ginseng has also shown some glycemic benefit when used in combination with other ingredients. Panax ginseng extract 750 mg (standardized to 30% ginsenosides) has been used in combination with American ginseng extract 1500 mg (standardized to 10% ginsenosides), viscous fiber 10 grams, and ground white chia seeds 60 grams daily for 24 weeks (105673). It is unclear if this benefit is due to Panax ginseng, other ingredients, or the combination.
Diabetic neuropathy. It is unclear if oral Panax ginseng is beneficial in diabetic neuropathy. Details: A small clinical study in patients with diabetic neuropathy shows that taking Panax ginseng extract powder 1 gram daily for 24 weeks seems to improve sensory perception of electric currents, a marker for severity of diabetic neuropathy, when compared with baseline (103051). The validity of this study was limited by the lack of statistical comparison between treatment and placebo groups.
Exercise-induced muscle damage. Although there has been interest in using oral Panax ginseng for exercise-induced muscle damage, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Fatigue. Most clinical research shows that oral Panax ginseng can reduce fatigue in adults with idiopathic chronic fatigue. However, not all research agrees. Details: Some clinical research in patients with idiopathic chronic fatigue or self-reported fatigue shows that taking Panax ginseng improves self-reported fatigue when compared with baseline or placebo (89743,23623,106665). A small clinical study in patients with idiopathic chronic fatigue shows that taking an ethanolic extract of Panax ginseng 1 gram twice daily for 4 weeks reduces self-reported fatigue by 66% and mental fatigue by 50% when compared with placebo (89743). Another clinical study in adults with chronic fatigue also shows that taking a specific combination product containing Panax ginseng (G115) 80 mg, vitamins, and minerals daily for 7 weeks alleviates fatigue symptoms in 20% more patients when compared with placebo (23623). However, not all research has been positive. A small clinical study in middle-aged patients with idiopathic chronic fatigue shows that taking Panax ginseng, steamed and aged for six years, 3 grams daily for 6 weeks is no different than placebo for reducing fatigue (103052). Notably, this clinical trial had a robust placebo effect.
Fibromyalgia. It is unclear if oral Panax ginseng is beneficial for fibromyalgia. Details: Clinical research shows that taking Panax ginseng root extract 100 mg daily orally for 12 weeks does not improve pain, fatigue, sleep quality, anxiety, tender point count, or quality of life when compared with placebo in patients with fibromyalgia (89744). A nonblinded, observational study in patients with fibromyalgia, most of whom also have severe chronic fatigue syndrome (CFS), shows that taking Panax ginseng daily for one month improves patient reports of energy, overall wellbeing, mental clarity, sleep, pain, and stamina when compared with baseline. Patients took Panax ginseng, either as a capsule (Terry Naturally HRG80 Red Ginseng Energy capsules; EuroPharma, Inc) 200-400 mg daily, or chewable tablet (Terry Naturally HRG80 Red Ginseng Energy chewable tablets; EuroPharma, Inc) 100-200 mg daily. There were no dose- or formulation-dependent differences between groups (107746). The validity of these findings is limited by the lack of randomization and placebo-control; additionally, the majority (89%) of patients included in this study were female.
Gallbladder disease. It is unclear if oral Panax ginseng is beneficial for gallbladder disease. Details: Clinical research shows that taking Panax ginseng 7.5 grams as an adjuvant to the bile acids chenodeoxycholic acid (CDCA) 500 mg daily plus ursodeoxycholic acid (UDCA) 500 mg daily, divided into three doses daily for 24 weeks, does not decrease the total volume of gallstones or increase gallstone dissolution when compared to use of bile acids alone (89748).
Gastritis. Although there has been interest in using oral Panax ginseng for gastritis, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Glaucoma. It is unclear if oral Panax ginseng is beneficial for glaucoma. Details: A clinical crossover study in patients with glaucoma shows that taking oral Panax ginseng 1 gram three times daily for 4 weeks improves dry eye severity, daytime visual function, and eye pain when compared with placebo. In a sub-group of patients with early or moderate glaucoma, nighttime visual function was also improved (107744). The validity of this study is limited due to short duration of treatment.
Halitosis. It is unclear if oral Panax ginseng is beneficial for halitosis. Details: Preliminary clinical research shows that taking Korean red ginseng, a type of Panax ginseng, 2.7 grams daily for 10 weeks helps reduce bad breath when compared with baseline, particularly in patients with bad breath caused by Helicobacter pylori (H. pylori) infection (23624). The validity of this finding is limited by the lack of a comparator group.
Hangover. It is unclear if oral Panax ginseng is beneficial for hangover. Details: One small clinical study shows that drinking 100 mL of a drink containing Panax ginseng extract 0.321 mg/mL within 5 minutes of drinking 100 mL blended Scotch whiskey with 40% alcohol and eating a piece of cheese may reduce hangover symptoms by approximately 66% when compared with placebo in healthy males. Levels of alcohol in the blood also appear to be reduced (89742).
Hearing loss. It is unclear if oral Panax ginseng is beneficial for hearing loss. Details: Preliminary clinical research in male textile workers exposed to continuous noise shows that taking Korean red ginseng, a type of Panax ginseng, 200 mg daily for 14 days reduces temporary hearing loss caused by noises at frequencies of 4, 6, or 16 kHz when compared with control. However, Panax ginseng may be slightly less effective than N-acetyl cysteine at preventing temporary hearing loss caused by noise at 4 kHz frequency (89739).
HIV/AIDS. It is unclear if oral Panax ginseng is beneficial for this condition. Details: Preliminary clinical research in adults with HIV shows that taking Korean red ginseng, a particular form of Panax ginseng, along with highly active antiretroviral therapy (HAART) modestly increases CD4 count, but does not affect viral load, when compared with HAART alone (23625).
Hyperlipidemia. It is unclear if oral Panax ginseng is beneficial for hyperlipidemia. Details: A meta-analysis of clinical studies in healthy adults and adults with a variety of metabolic disorders shows that taking Panax ginseng 200 mg to 8 grams daily for 4 to 24 weeks reduces total cholesterol by 7 mg/dL and low-density lipoprotein (LDL) cholesterol by 9 mg/dL but does not reduce triglycerides or increase high-density lipoprotein (HDL) cholesterol when compared with placebo (112838). However, a meta-analysis of up to 28 clinical studies in healthy adults and adults with a variety of metabolic disorders shows that taking Panax ginseng 300 mg to 6 grams daily for 3 to 32 weeks does not reduce total or LDL cholesterol or triglycerides or increase HDL cholesterol when compared with placebo (114985).
Hypertension. It is unclear if oral Panax ginseng is beneficial for hypertension. Details: A meta-analysis of clinical studies in healthy adults and adults with a variety of metabolic disorders shows that taking Panax ginseng 200 mg to 8 grams daily for 4 to 24 weeks does not reduce systolic (SBP) or diastolic (DBP) blood pressure when compared with placebo. However, subgroup analysis suggests that Panax ginseng might modestly reduce SBP in people with prehypertension, hypertension, or metabolic syndrome (112838). Smaller individual studies of various forms of Panax ginseng have been evaluated in patients with mild to severe hypertension with conflicting results. Some preliminary clinical research in patients with essential hypertension shows that taking Panax ginseng 4.5 grams daily in three divided doses, alone or with a beta-blocker or calcium channel blocker for 8 weeks, moderately decreases 24-hour SBP (23632). However, in patients with prehypertension or mild hypertension, taking protopanaxatriol-enriched Panax ginseng (Ginseol K-g1) 100 mg or 300 mg daily for 8 weeks does not reduce seated SBP or DBP when compared with placebo (89741). Panax ginseng has also been evaluated in combination with American ginseng. Clinical studies in patients with hypertension with or without type 2 diabetes show that taking Panax ginseng 0.75 grams and American ginseng 1.5-2.25 grams enriched to contain 30% total ginsenosides daily for 12 weeks reduces central SBP by about 5 mmHg and 24-hour SBP by about 4 mmHg, but does not impact DBP, when compared with placebo or a control of wheat-bran (103046,107745). Patients receiving this combination also have greater reductions in daytime SBP, glycated hemoglobin, total cholesterol levels, and triglyceride levels when compared with control (107745). It is unclear if these effects are due to Panax ginseng, American ginseng, or the combination; additionally, it is unclear if enrichment with ginsenosides alters clinical effects.
Impaired glucose tolerance (prediabetes). It is unclear if oral Panax ginseng is beneficial for impaired glucose tolerance. Details: In overweight adults with prediabetes, a small clinical study shows that taking hydrolyzed Panax ginseng extract, 320 mg three times daily before meals for 6 months, does not improve fasting blood glucose levels. However, compliance in this study was only 49% (104953). Additionally, a large, cross-over, clinical study in patients with prediabetes initiating a lifestyle intervention shows that taking a Chinese herbal medicine preparation containing Panax ginseng providing ginseng berry saponins 50 mg three times daily for 4 weeks improves 2-hour post-prandial glucose, but not fasting blood glucose, when compared with placebo (114980). Panax ginseng has also been studied in combination with other ingredients. One clinical study shows that taking a combination of Korean red ginseng, a type of Panax ginseng, and cheonggukjang, a type of fermented soybean paste, 20 grams daily for 8 weeks can decrease fasting blood glucose levels by 17% in patients with prediabetes (23640). Also, taking fermented Panax ginseng 2.7 grams daily for 4 weeks reduces 2-hour postprandial glucose by about 17% and increases 2-hour postprandial insulin levels by about 44% when compared to baseline; when compared with placebo, these changes are significant (89740). It is unclear if these effects are due to Panax ginseng, other ingredients, or the combinations.
Inflammatory bowel disease (IBD). Although there has been interest in using oral Panax ginseng for Crohn disease and ulcerative colitis, there is insufficient reliable information about the clinical effects of Panax ginseng for these conditions.
Insomnia. Although there has been interest in using oral Panax ginseng for insomnia, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Liver disease. Although there has been interest in using oral Panax ginseng for liver diseases, there is insufficient reliable information about the clinical effects of Panax ginseng for these conditions.
Male infertility. It is unclear if oral Panax ginseng is beneficial for male infertility. Details: Chronic prostatitis due to Chlamydia trachomatis infection is associated with reduced male fertility due to decreased sperm concentration and motility. Preliminary clinical research in adults with this condition shows that taking 25 mL of a specific product containing L-arginine 1660 mg, L-carnitine 150 mg, acetyl-L-carnitine 50 mg, and Panax ginseng 200 mg (Fertimev) along with prulifloxacin 600 mg daily for 6 months improves sperm concentration and sperm motility when compared to treatment with prulifloxacin alone (59006). It is unclear if this effect is due to Panax ginseng, other ingredients, or the combination.
Menopausal symptoms. Research on oral Panax ginseng for menopausal symptoms has yielded conflicting results. Details: One clinical study in postmenopausal adults shows that taking Panax ginseng extract (G115) 200 mg daily orally for 16 weeks does not improve psychological well-being or reduce vasomotor symptoms such as hot flashes when compared with placebo (10981). However, several smaller clinical studies in postmenopausal adults demonstrate beneficial effects with higher doses of Panax ginseng. One study shows that taking Panax ginseng 1 gram (containing 30 mg ginsenosides) three times daily for 12 weeks reduces hot flashes and other symptoms, as measured by the Kupperman index and the Menopause Rating Scale (MRS), when compared with placebo (89749). Another study shows that taking an extract of Korean red ginseng, a specific form of Panax ginseng, 500 mg 4 times daily for 8 weeks improves fatigue severity scores by 21%, compared with 3% in those receiving placebo (106666). In premenopausal adults with menopausal symptoms following surgery for gynecologic cancer, taking Panax ginseng 1 gram three times daily for 12 weeks reduces the total symptom score on the MRS when compared with baseline. However, there was also a robust response in the placebo group, with no significant difference in symptom reduction between groups (104596). Panax ginseng has also been evaluated for improving genitourinary syndrome and cognition after menopause. A small clinical trial in postmenopausal adults with genitourinary syndrome shows that taking a specific Panax ginseng supplement (Ruginseng, Ghaem Daru Pharmaceutical) 500 mg twice daily for 4 weeks does not affect vaginal maturation index or pH, but seems to improve patient-rated symptoms such as vaginal itching and burning, when compared with a lactose placebo (105670). This study was funded by the supplement manufacturer. In another clinical study, taking a specific combination product (Gincosan) containing Panax ginseng 200 mg and ginkgo 120 mg daily for 6-12 weeks does not improve cognition, memory, mood, anxiety, or sleep when compared with placebo (87767).
Metabolic syndrome. It is unclear if oral Panax ginseng is beneficial for metabolic syndrome. Details: A meta-analysis of 23 clinical studies in healthy adults, menopausal adults, and adults with a variety of metabolic disorders shows that taking Panax ginseng 200 mg to 8 grams daily for 4 to 24 weeks reduces glucose area under the plasma concentration-time curve (AUC), total cholesterol, and high-density lipoprotein cholesterol, but does not improve other measures of blood glucose, insulin resistance, blood pressure, lipids, or anthropometric measures when compared with placebo (112838). Additionally, a small clinical study in adults with metabolic syndrome shows that taking Korean red ginseng, a specific form of Panax ginseng, 6 grams daily for 8 weeks modestly reduces systolic blood pressure from baseline, but not when compared with placebo. Additionally, Panax ginseng has no effect on anthropometric measurements, biochemical markers, or other vital signs when compared with placebo (106667).
Nausea and vomiting. Although there has been interest in using oral Panax ginseng for nausea and vomiting, there is insufficient reliable information about the clinical effects of Panax ginseng for these conditions.
Neuropathic pain. Although there has been interest in using oral Panax ginseng for neuropathic pain, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral Panax ginseng is beneficial for NAFLD. Details: A small clinical study in adults with NAFLD shows that taking Panax ginseng 2 grams (containing ginsenosides 4.5 mg/gram) daily for 30 days modestly reduces fatigue and plasma levels of alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT) when compared with placebo. All patients were also given milk thistle dried extract 450 mg (Legalon, Bukwang Pharmaceutical) daily and asked to exercise daily for at least 30 minutes (105671).
Oral cancer. It is unclear if topical Panax ginseng is beneficial for oral health in patients with oral cancer. Details: A small clinical study in patients with oral cancer and poor oral hygiene shows that rinsing with a specific herbal mouthwash (Dr. Dental care liquid, Jangin Pharm Co., Ltd.) containing Panax ginseng 8 mL for 1 minute twice daily for 14 days reduces oral bacterial load and improves oral hygiene and gingival indices when compared with chlorhexidine or saline rinses (114987).
Osteoarthritis. It is unclear if oral Panax ginseng is beneficial for osteoarthritis of the hand. Details: A small clinical study in postmenopausal adults with degenerative osteoarthritis of the hand shows that taking oral Korean red ginseng, a type of Panax ginseng, 1 gram three times daily for 12 weeks improves pain scores at rest, during daily activity, and at work or sport, and also improves disabilities of the arm, shoulder, and hand (DASH) score when compared with placebo (107747). The validity of this trial is limited due to the lack of objective outcome measures.
Pneumonia. Injectable Panax ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Oral Panax ginseng has not been evaluated for this use. Details: A meta-analysis of 20 small, low-quality randomized and non-randomized studies in older Chinese adults with severe pneumonia shows that administering an injection containing Panax ginseng extract 0.8 mg/mL and aconite extract 0.1 mg/mL in addition to standard treatment leads to improvement in symptoms such as fever, cough, and chest tightness in 77% of patients as compared with 61% of those who received standard treatment alone. This combination injection may also modestly reduce disease severity and the risk of mortality when compared with standard treatment alone. However, these outcomes were not evaluated in all studies, and dosing regimens were heterogenous (110472). Additionally, it is unclear whether these effects are due to Panax ginseng, aconite, or the combination.
Premature ejaculation. Oral Panax ginseng has primarily been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Applying a multi-ingredient cream preparation containing Panax ginseng, angelica root, Cistanches deserticola, Zanthoxyl species, torlidis seed, clove flower, asiasari root, cinnamon bark, and toad venom (SS Cream) to the glans penis one hour prior to intercourse and washing off immediately before intercourse seems to improve ejaculatory latency in adults with premature ejaculation when compared with placebo (2537). It is unclear if this effect is due to Panax ginseng, other ingredients, or the combination.
Quality of life. It is unclear if oral Panax ginseng is beneficial for quality of life. Details: While some research suggests that Panax ginseng might improve self-rated quality of life (6254,23644), other studies show no benefit (8601,10314). In studies showing benefit for quality of life, doses have included one capsule daily of a specific Panax ginseng extract (Pharmaton Capsules, Pharmaton Natural Health Products) for 12 weeks (6254) and Panax ginseng extract (G115) 40 mg twice daily for 12 weeks (23644).
Rheumatoid arthritis (RA). It is unclear if oral Panax ginseng is beneficial for improving symptoms of RA. Details: A moderate-sized clinical study in patients with RA, Sjogren syndrome, or both shows that taking Panax ginseng 2000 mg daily for 3 months does not improve fatigue scores when compared with placebo (114984).
Sjogren syndrome. It is unclear if oral Panax ginseng is beneficial in patients with Sjogren syndrome. Details: A moderate-sized clinical study in patients with RA, Sjogren syndrome, or both shows that taking Panax ginseng 2000 mg daily for 3 months does not improve fatigue scores when compared with placebo (114984).
Stress. It is unclear if oral Panax ginseng is beneficial for stress. Details: A small clinical study in healthy patients with occupational stress shows that taking a specific Panax ginseng root preparation (HRG80) high in ginsenosides daily for 14 days modestly reduces perceived stress and improves attention and memory when compared with placebo. However, taking a standard Panax ginseng preparation with a lower quantity of ginsenosides was no better than placebo (103050). However, a moderate-sized clinical study in adult males shows that taking Panax ginseng 2000 mg daily for 8 weeks does not improve self-reported stress response when compared with placebo (114988).
Stroke. It is unclear if oral Panax ginseng prevents stroke. Details: A small clinical study in adults with severe atherosclerosis in major intracranial arteries or extracranial carotid arteries at high risk for ischemic stroke shows that taking an extract of Korean red ginseng, a type of Panax ginseng, 1000 mg twice daily for 12 months does not prevent transient ischemic attack or ischemic stroke and does not improve neurological disability, cerebral blood flow, or the incidence of new ischemic brain lesions when compared with placebo (112835).
Traumatic brain injury (TBI). It is unclear if oral Panax ginseng is beneficial for asthenic syndrome due to TBI. Details: A small study in adults with asthenic syndrome secondary to mild combat TBI shows that taking Panax ginseng improves autonomic nervous system functioning and asthenic symptoms when compared to baseline (112834). The validity of these effects is limited by a lack of a comparator group.
Vascular dementia. Oral Panax ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients aged 60 years or older with vascular dementia shows that taking a supplement containing extracts of Panax ginseng, ginkgo, and saffron three times daily for 16 weeks modestly improves some cognitive function scores, caregiver assessed activities of daily living, and patient-reported quality of life when compared with placebo. However, these effects were not maintained after patients stopped taking the supplement (111336). Additionally, it is unclear if these effects are due to Panax ginseng, other ingredients, or the combination.
Wrinkled skin. It is unclear if oral Panax ginseng is beneficial for wrinkled skin. Details: Preliminary clinical research shows that taking 3 grams of a combination of Korean red ginseng root with Torilus fructus and Corni fructus daily for 24 weeks may reduce wrinkles when compared with placebo. However, it does not seem to affect skin elasticity, moisture, thickness, or color (23645). It is unclear if this benefit is due to Panax ginseng, other ingredients, or the combination. More evidence is needed to rate Panax ginseng for these uses.

Details: A small clinical study in adults with acute, nonspecific pneumonia shows that taking 20 mL of a specific combination product (ADAPT-232 CHI San, Swedish Herbal Institute) containing schisandra berry extract 51%, rhodiola root extract 27.6%, and eleuthero root extract 24.4% twice daily for 10-15 days reduces the duration of antibiotic treatment and may improve quality of life when compared with standard treatment alone (71152). It is unclear if these effects are due to schisandra, other ingredients, or the combination.
Stress. Oral schisandra has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy, fatigued females under experimental stress suggests that taking a single, 270 mg dose of a combination product (ADAPT-232, Swedish Herbal Institute) containing schisandra, rhodiola, and Siberian ginseng improves attention, as well as cognitive task speed and accuracy, when compared with placebo (19289). It is unclear if these effects are due to schisandra, other ingredients, or the combination. More evidence is needed to rate schisandra for these uses.

WILD YAM

POSSIBLY INEFFECTIVE

Menopausal symptoms. Topical wild yam does not seem to improve menopausal symptoms. Details: Wild yam applied topically as a cream in menopausal patients for 3 months appears to be no better than placebo for relieving vasomotor symptoms, such as hot flashes and night sweats. It also does not appear to change serum follicle stimulating hormone (FSH), estradiol, or progesterone levels (10989).

Cognitive function. It is unclear if oral wild yam is beneficial for improving cognitive function in healthy adults. Details: Preliminary clinical research in healthy adults shows that taking a specific wild yam extract (Diopower 15, Anti-Aging Pro Corporation) orally, 50 mg (containing diosgenin 8 mg) daily for 12 weeks, modestly improves overall measures of cognitive function and semantic fluency when compared with placebo (96724).

Interactions with Drugs view details

Below is general information about the interactions of the known ingredients contained in the product Adrenal. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

ASTRAGALUS

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = A

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.

Details

Clinical research in humans shows that astragalus might have hypoglycemic effects (95909,112809,114805). Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.

CYCLOPHOSPHAMIDE

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, astragalus might interfere with cyclophosphamide therapy.

Details

Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression (3713). However, other animal research shows no effect (418).

IMMUNOSUPPRESSANTS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, astragalus might interfere with immunosuppressive therapy.

Details

Astragalus seems to stimulate immune function (303,10777). Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

LITHIUM

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = D

Theoretically, astragalus might increase levels and adverse effects of lithium.

Details

Animal research suggests that astragalus has diuretic properties (15103). Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.

ANTICOAGULANT/ANTIPLATELET DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Unlikely • Level of Evidence = B

Although Panax ginseng has shown antiplatelet effects in the laboratory, it is unlikely to increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.

Details

In vitro evidence suggests that ginsenoside constituents in Panax ginseng might decrease platelet aggregation (1522,11891). However, research in humans suggests that ginseng does not affect platelet aggregation (11890). Animal research indicates low oral bioavailability of Rb1 and rapid elimination of Rg1, which might explain the discrepancy between in vitro and human research (11153). Until more is known, use with caution in patients concurrently taking anticoagulant or antiplatelet drugs.

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Theoretically, taking Panax ginseng with antidiabetes drugs might increase the risk of hypoglycemia.

Details

Clinical research suggests that Panax ginseng might decrease blood glucose levels (89740). Monitor blood glucose levels closely.

CAFFEINE

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Theoretically, taking Panax ginseng with caffeine might increase the risk of adverse stimulant effects.

Details

Panax ginseng has been shown to have stimulant effects (589,594). Theoretically, caffeine might have an additive effect on the stimulant effects of Panax ginseng.

CYTOCHROME P450 1A1 (CYP1A1) SUBSTRATES

Interaction Rating = Minor Be watchful with this combination.

Severity = Mild • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might decrease levels of drugs metabolized by CYP1A1.

Details

In vitro research shows that Panax ginseng can induce the CYP1A1 enzyme (24104).

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Theoretically, Panax ginseng might increase levels of drugs metabolized by CYP2D6. However, research is conflicting.

Details

There is some evidence that Panax ginseng can inhibit the CYP2D6 enzyme by approximately 6% (1303,51331). In addition, in animal research, Panax ginseng inhibits the metabolism of dextromethorphan, a drug metabolized by CYP2D6, by a small amount (103478). However, contradictory research suggests Panax ginseng might not inhibit CYP2D6 (10847). Until more is known, use Panax ginseng cautiously in patients taking drugs metabolized by these enzymes.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Theoretically, Panax ginseng might increase or decrease levels of drugs metabolized by CYP3A4.

Details

Panax ginseng may affect the clearance of drugs metabolized by CYP3A4. One such drug is imatinib. Inhibition of CYP3A4 was believed to be responsible for a case of imatinib-induced hepatotoxicity (89764). In contrast, Panax ginseng has been shown to increase the clearance of midazolam, another drug metabolized by CYP3A4 (89734,103478). Clinical research shows that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29% (89734). Midazolam metabolism was also increased in animals given Panax ginseng (103478). Until more is known, use Panax ginseng cautiously in combination with CYP3A4 substrates.

ESTROGENS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, concomitant use of large amounts of Panax ginseng might interfere with hormone replacement therapy.

Details

Laboratory research and some case reports suggest that Panax ginseng can have estrogenic effects due to competition for estrogen receptors (590,591,592,6180,10982,10983,10984). The estrogenic activity is attributed to the ginsenoside constituents of Panax ginseng (10984).

FEXOFENADINE (Allegra)

Interaction Rating = Minor Be watchful with this combination.

Severity = Mild • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might decrease blood levels of oral or intravenous fexofenadine.

Details

Animal research suggests that taking Panax ginseng in combination with oral or intravenous fexofenadine may reduce the bioavailability of fexofenadine. Some scientists have attributed this effect to the ability of Panax ginseng to increase the expression of P-glycoprotein (24101).

FUROSEMIDE (Lasix)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might reduce the effects of furosemide.

Details

There is some concern that Panax ginseng might contribute to furosemide resistance. There is one case of resistance to furosemide diuresis in a patient taking a germanium-containing ginseng product (770).

IMATINIB (Gleevec)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might increase the effects and adverse effects of imatinib.

Details

A case of imatinib-induced hepatotoxicity has been reported for a 26-year-old male with chronic myelogenous leukemia stabilized on imatinib for 7 years. The patient took imatinib 400 mg along with a Panax ginseng-containing energy drink daily for 3 months. Since imatinib-associated hepatotoxicity typically occurs within 2 years of initiating therapy, it is believed that Panax ginseng affected imatinib toxicity though inhibition of cytochrome P450 3A4. CYP3A4 is the primary enzyme involved in imatinib metabolism (89764).

IMMUNOSUPPRESSANTS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = B

Theoretically, Panax ginseng use might interfere with immunosuppressive therapy.

Details

Panax ginseng might have immune system stimulating properties (3122).

INSULIN

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Theoretically, taking Panax ginseng with insulin might increase the risk of hypoglycemia.

Details

Clinical research suggests that Panax ginseng might decrease blood glucose levels (89740). Insulin dose adjustments might be necessary in patients taking Panax ginseng; use with caution.

LOPINAVIR/RITONAVIR (Kaletra)

Interaction Rating = Minor Be watchful with this combination.

Severity = Insignificant • Occurrence = Unlikely • Level of Evidence = B

Although Panax ginseng has demonstrated variable effects on cytochrome P450 3A4 (CYP3A4), which metabolizes lopinavir, Panax ginseng is unlikely to alter levels of lopinavir/ritonavir.

Details

Lopinavir is metabolized by CYP3A4 and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Panax ginseng has shown variable effects on CYP3A4 activity in humans (89734,89764). However, taking Panax ginseng (Vitamer Laboratories) 500 mg twice daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in 12 healthy volunteers (93578).

MIDAZOLAM (Versed)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Theoretically, Panax ginseng may increase the clearance of midazolam.

Details

Midazolam is metabolized by cytochrome P450 3A4 (CYP3A4). Clinical research suggests that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29% (89734). Midazolam metabolism was also increased in animals given Panax ginseng (103478).

MONOAMINE OXIDASE INHIBITORS (MAOIs)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = D

Theoretically, Panax ginseng can interfere with MAOI therapy.

Details

Concomitant use of Panax ginseng with phenelzine (Nardil) is associated with insomnia, headache, tremors (617), and hypomania (618,23650).

NIFEDIPINE (Procardia)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Theoretically, taking Panax ginseng with nifedipine might increase serum levels of nifedipine and the risk of hypotension.

Details

Preliminary clinical research shows that concomitant use can increase serum levels of nifedipine in healthy volunteers (22423). This might cause the blood pressure lowering effects of nifedipine to be increased when taken concomitantly with Panax ginseng.

QT INTERVAL-PROLONGING DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = B

Theoretically, Panax ginseng has an additive effect with drugs that prolong the QT interval and potentially increase the risk of ventricular arrhythmias. However, research is conflicting.

Details

Clinical research shows that short-term use of Panax ginseng can increase the QT interval (4322,96218). However, no changes in QT interval have been identified with prolonged use (4322).

RALTEGRAVIR (Isentress)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, taking Panax ginseng with raltegravir might increase the risk of liver toxicity.

Details

A case report suggests that concomitant use of Panax ginseng with raltegravir can increase serum levels of raltegravir, resulting in elevated liver enzymes levels (23621).

SELEGILINE (Eldepryl)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might increase or decrease levels of selegiline, possibly altering the effects and side effects of selegiline.

Details

Animal research shows that taking selegiline with a low dose of Panax ginseng extract (1 gram/kg) reduces selegiline bioavailability, while taking a high dose of Panax ginseng extract (3 grams/kg) increases selegiline bioavailability (103053). More research is needed to confirm these effects.

STIMULANT DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, taking Panax ginseng with stimulant drugs might increase the risk of adverse stimulant effects.

Details

Panax ginseng has been shown to have stimulant effects (589,594).

WARFARIN (Coumadin)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Unlikely • Level of Evidence = B

Panax ginseng might affect the clearance of warfarin. However, this interaction appears to be unlikely.

Details

There has been a single case report of decreased effectiveness of warfarin in a patient who also took Panax ginseng (619). However, it is questionable whether Panax ginseng was the cause of this decrease in warfarin effectiveness. Some research in humans and animals suggests that Panax ginseng does not affect the pharmacokinetics of warfarin (2531,11890,17204,24105). However, other research in humans suggests that Panax ginseng might modestly increase the clearance of the S-warfarin isomer (15176). More evidence is needed to determine whether Panax ginseng causes a significant interaction with warfarin.

SCHISANDRA

CYCLOPHOSPHAMIDE

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = D

Theoretically, schisandra might increase the levels and clinical effects of cyclophosphamide.

Details

In vitro research shows that schisandra increases the concentration of cyclophosphamide, likely through inhibition of cytochrome P450 3A4. After multiple doses of the schisandra constituents schisandrin A and schisantherin A, the maximum concentration of cyclophosphamide was increased by 7% and 75%, respectively, while the overall exposure to cyclophosphamide was increased by 29% and 301%, respectively (109636).

CYCLOSPORINE (Neoral, Sandimmune)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Schisandra can increase the levels and clinical effects of cyclosporine.

Details

A small observational study in children with aplastic anemia found that taking schisandra with cyclosporine increased cyclosporine trough levels by 93% without increasing the risk of adverse events. However, the dose of cyclosporine was reduced in 9% of children to maintain appropriate cyclosporine blood concentrations (109637).

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = D

Theoretically, schisandra might increase the levels and clinical effects of CYP2C19 substrates.

Details

In vitro research shows that schisandra inhibits CYP2C19, and animal research shows that schisandra increases the concentration of voriconazole, a CYP2C19 substrate (105566). Theoretically, schisandra may also inhibit the metabolism of other CYP2C19 substrates. This effect has not been reported in humans.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, schisandra might decrease the levels and clinical effects of CYP2C9 substrates.

Details

In vitro and animal research suggests that schisandra induces CYP2C9 enzymes (14441). This effect has not been reported in humans.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = D

Schisandra can increase the levels and clinical effects of drugs metabolized by CYP3A4.

Details

Most clinical and laboratory research shows that schisandra, administered either as a single dose or up to twice daily for 14 days, inhibits CYP3A4 and increases the concentration of CYP3A4 substrates such as cyclophosphamide, midazolam, tacrolimus, and talinolol (13220,17414,23717,91386,91388,91387,96631,105564,109636,109638,109639,109640,109641). Although one in vitro and animal study shows that schisandra may induce CYP3A4 metabolism (14441), this effect appears to be overpowered by schisandra's CYP3A4 inhibitory activity and has not been reported in humans.

MIDAZOLAM (Versed)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Schisandra can increase the levels and clinical effects of midazolam.

Details

A small pharmacokinetic study in healthy adults shows that taking schisandra extract (Hezheng Pharmaceutical Co.) containing deoxyschizandrin 33.75 mg twice daily for 8 days and a single dose of midazolam 15 mg on day 8 increases the overall exposure to midazolam by about 119%, increases the peak plasma level of midazolam by 86%, and decreases midazolam clearance by about 52%. This effect has been attributed to inhibition of CYP3A4 by schisandra (91388).

P-GLYCOPROTEIN SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Schisandra might increase the levels and clinical effects of P-glycoprotein substrates.

Details

In vitro research shows that schisandra extracts and constituents such as schisandrin B inhibit P-glycoprotein mediated efflux in intestinal cells and in P-glycoprotein over-expressing cell lines (17414,105643,105644). Additionally, a small clinical study shows that schisandra increases the peak concentration and overall exposure to talinolol, a P-glycoprotein probe substrate (91386). Theoretically, schisandra might inhibit the efflux of other P-glycoprotein substrates.

SIROLIMUS (Rapamune)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Schisandra can increase the levels and clinical effects of sirolimus.

Details

A small pharmacokinetic study in healthy volunteers shows that taking 3 capsules of schisandra (Hezheng Pharmaceutical Company) containing a total of 33.75 mg deoxyschizandrin twice daily for 13 days and then taking a single dose of sirolimus 2 mg increases the overall exposure and peak level of sirolimus by two-fold. This effect is thought to be due to inhibition of cytochrome P450 3A4 by schisandra, as well as possible inhibition of the P-glycoprotein drug transporter (105643).

TACROLIMUS (Prograf)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Schisandra can increase the levels and clinical effects of tacrolimus.

Details

Clinical research in healthy children and adults, transplant patients, and patients with nephrotic syndrome and various rheumatic immunologic disorders shows that taking schisandra with tacrolimus increases tacrolimus peak levels by 183% to 268%, prolongs or delays time to peak tacrolimus concentrations, increases overall exposure to tacrolimus by 126% to 343%, and decreases tacrolimus clearance by 19% to 73% (17414,91387,15570,96631,105623,109638,109639,109640,109641,112889)(112890,112972,112973,112974). This effect is thought to be due to inhibition of P-glycoprotein drug transporter and CYP3A4 and CYP3A5 by schisandra (17414,96631,105623,105643,105644,112974). Some clinical and observational studies suggest that schisandra increases tacrolimus levels similarly in both expressors and non-expressors of CYP3A5, while other studies suggest it does so to a greater degree in CYP3A5 expressors than non-expressors (105623,109638,109639,109640,112889,112890,112973,112974). Animal research suggests that the greatest increase in tacrolimus levels occurs when schisandra is taken either concomitantly or up to 2 hours before tacrolimus (105564), and clinical and observational research in humans suggests that schisandra may increase whole blood levels of tacrolimus and decrease clearance of tacrolimus in a dose-dependent manner (109639,109640,112972).

TALINOLOL

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Schisandra can increase the levels and clinical effects of talinolol.

Details

A small pharmacokinetic study in healthy volunteers shows that taking schisandra extract 300 mg twice daily for 14 days with a single dose of talinolol 100 mg on day 14 increases the peak talinolol level by 51% and the overall exposure to talinolol by 47%. This effect is thought to be due to the possible inhibition of cytochrome P450 3A4 and P-glycoprotein by schisandra (91386). tly.

VORICONAZOLE (Vfend)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, schisandra might increase the levels and clinical effects of voriconazole.

Details

Animal research shows that oral schisandra given daily for 1 or 14 days increases levels of intravenously administered voriconazole, a cytochrome P450 (CYP) 2C19 substrate. This effect is thought to be due to inhibition of CYP2C19 by schisandra (105566). However, this interaction has not been reported in humans.

WARFARIN (Coumadin)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, schisandra might decrease the levels and clinical effects of warfarin.

Details

Animal research suggests that oral schisandra extract, given daily for 6 days, reduces levels of intravenously administered warfarin. This effect might be due to the induction of cytochrome P450 (CYP) 2C9 metabolism by schisandra (14441). However, this interaction has not been reported in humans.

WILD YAM

ESTROGENS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, wild yam might increase or decrease the effects of estrogen.

Details

Wild yam root shows estrogenic and anti-estrogenic effects in vitro (6180,70411,96723,96725). Theoretically, wild yam might interfere with hormone therapy.

Adverse Effects view details

Below is general information about the adverse effects of the known ingredients contained in the product Adrenal. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

ASTRAGALUS

General ...Orally and intravenously, astragalus root seems to be well tolerated. Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: A case report raises concerns about liver and kidney cysts with astragalus use.

Cardiovascular ...Orally, astragalus has reportedly been associated with lacunar angina in one clinical trial. However, this may not have been caused by astragalus (17355). In addition, rapid intravenous administration of astragalus has resulted in temporary palpitations (32812).

Dermatologic ...Intravenously, astragalus may cause rash, eczema, and pruritus (33034).

Gastrointestinal ...Orally, astragalus has reportedly been associated with enterocolitis and nausea in one clinical trial. However, these effects may not have been caused by astragalus (17355).

Genitourinary ...Orally, astragalus has reportedly been associated with vulvitis in one clinical trial. However, this effect may not have been caused by astragalus (17355).

Hepatic ...A case of high serum CA19-9 levels and small liver and kidney cysts has been reported for a 38-year-old woman who drank astragalus tea daily for one month. Levels returned to normal after one month, and cysts disappeared after ten months. Both symptoms returned following a resumption of astragalus use. The authors state that astragalus was the likely cause given the temporal relationship (90658).

Musculoskeletal ...Orally, astragalus has been associated with reports of musculoskeletal pain in one clinical trial. However, these effects may not have been caused by astragalus (114803).

Neurologic/CNS ...Intravenously, administration of astragalus has been associated with temporary dizziness in patients with heart failure in clinical research (32812,114804). Orally, astragalus has also been associated with dizziness in one clinical study. However, these effects may not have been caused by astragalus (114803).

Pulmonary/Respiratory ...Orally, astragalus has reportedly been associated with rhinosinusitis and pharyngitis in one clinical trial. However, these effects may not have been caused by astragalus (17355).

Renal ...A case of high serum CA19-9 levels and small liver and kidney cysts has been reported for a 38-year-old woman who drank astragalus tea daily for one month. Levels returned to normal after one month, and cysts disappeared after ten months. Both symptoms returned following a resumption of astragalus use. The authors state that astragalus was the likely cause given the temporal relationship (90658).

General ...Orally, Panax ginseng is generally well tolerated when used for up to 6 months. There is some concern about the long-term safety due to potential hormone-like effects.
Topically, no adverse effects have been reported when ginseng is used as a single ingredient. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Insomnia.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis, arrhythmia, ischemia, Stevens-Johnson syndrome.

Cardiovascular ...Panax ginseng may cause hypertension, hypotension, and edema when used orally in high doses, long-term (3353). However, single doses of Panax ginseng up to 800 mg are not associated with changes in electrocardiogram (ECG) parameters or increases in heart rate or blood pressure (96218). There is a case report of menometrorrhagia and tachyarrhythmia in a 39-year-old female who took Panax ginseng 1000-1500 mg/day orally and also applied a facial cream topically that contained Panax ginseng. Upon evaluation for menometrorrhagia, the patient also reported a history of palpitations. It was discovered that she had sinus tachycardia on ECG. However, the patient was a habitual consumer of coffee 4-6 cups/day and at the time of evaluation was also mildly anemic. The patient was advised to discontinue taking Panax ginseng. During the 6 month period following discontinuation the patient did not have any more episodes of menometrorrhagia or tachyarrhythmia (13030). Also, a case of transient ischemic attack secondary to a hypertensive crisis has been reportedly related to oral use of Panax ginseng (89402).

Dermatologic ...Orally, Panax ginseng may cause itching or an allergic response consisting of systemic rash and pruritus (89743,89760,104953,114984,114985). Skin eruptions have also been reported with use of Panax ginseng at high dosage, long-term (3353). Uncommon side effects with oral Panax ginseng include Stevens-Johnson syndrome (596).
In one case report, a 6-year-old male with a previous diagnosis of generalized pustular psoriasis, which had been in remission for 18 months, presented with recurrent pustular lesions after consuming an unspecified dose of Panax ginseng. The patient was diagnosed with pityriasis amiantacea caused by subcorneal pustular dermatosis. Treatment with oral dapsone 25 mg daily was initiated, and symptoms resolved after 4 weeks (107748). In another case report, a 26-year-old female presented with itchy exanthem and oval erythematous lesions on the face, neck, and abdomen after consuming a decoction containing Panax ginseng, aconite, ginger, licorice, Cassia cinnamon, goldthread, and peony 400 mL twice daily for 1 week. Pityriasis rosea-like eruption was suspected, but the patient refused topical or oral antihistamines or corticosteroids. The patient continued taking the decoction but with Panax ginseng and aconite removed. After 6 days, symptoms began to resolve, and by 17 days symptom improvement was significant (114986). It is unclear if this reaction was due to Panax ginseng, aconite, the combination, or some other factor. Pityriasis rosea typically resolves spontaneously.
Topically, when a specific multi-ingredient cream preparation (SS Cream) has been applied to the glans penis, mild pain, local irritation, and burning have occurred (2537).

Endocrine ...The estrogenic effects of ginseng are controversial. Some clinical evidence suggests it doesn't have estrogen-mediated effects (10981). However, case reports of ginseng side effects such as postmenopausal vaginal bleeding suggest estrogenic activity (590,591,592,10982,10983).
In a 12-year-old Korean-Japanese male, enlargement of both breasts with tenderness in the right breast (gynecomastia) occurred after taking red ginseng extract 500 mg daily orally for one month. Following cessation of the product, there was no further growth or pain (89733). Swollen and tender breasts also occurred in a 70-year-old female using Panax ginseng orally (590).

Gastrointestinal ...Orally, Panax ginseng can cause decreased appetite (3353), constipation, diarrhea, dyspepsia (3353,89734,103477,112841,114980,114985), abdominal pain (89734,87984,112841,114985), and nausea (589,87984). However, these effects are typically associated with long-term, high-dose usage (3353). Some evidence suggests that fermented Panax ginseng is more likely to cause abdominal pain and diarrhea when compared with unfermented Panax ginseng (112841).

Genitourinary ...Amenorrhea has been reported with oral use of Panax ginseng (3353).
Topically, when a specific multi-ingredient cream preparation (SS Cream) has been applied to the glans penis, sporadic erectile dysfunction and excessively delayed ejaculation have occurred (2537). Less commonly, patients can experience vaginal bleeding (591,592,3354,23630).

Hepatic ...It is unclear if Panax ginseng is associated with adverse hepatic effects. Cholestatic hepatitis has been reported in a 65-year old male following oral use of a combination product containing Panax ginseng and other ingredients (Prostata). However, it is unclear if this adverse effect was due to Panax ginseng, other ingredients, or the combination (598). An elevation in liver enzymes has been rarely reported in clinical research (114985).

Immunologic ...A case of anaphylaxis, with symptoms of hypotension and rash, has been reported following ingestion of a small amount of Panax ginseng syrup (11971).

Neurologic/CNS ...Orally, one of the most common side effects to Panax ginseng is insomnia (589,89734,111336,114985). Headache (594,23638,112840,114985), vertigo, euphoria, and mania (594) have also been reported. Migraine and somnolence occurred in single subjects in a clinical trial (87984). In a case report of a 46-year-old female, orobuccolingual dyskinesia occurred following oral use of a preparation containing black cohosh 20 mg and Panax ginseng 50 mg twice daily for menopausal symptoms. The patient's condition improved once the product was stopped and treatment with baclofen 40 mg and clonazepam 20 mg daily was started (89735).

SCHISANDRA

General ...Orally, schisandra seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Decreased appetite, heartburn, stomach upset, and urticaria.

Dermatologic ...Orally, schisandra can cause urticaria in some patients (11).

Gastrointestinal ...Orally, schisandra can cause heartburn, decreased appetite, and stomach upset (11).

WILD YAM

General ...Orally, wild yam is generally well tolerated.
Most Common Adverse Effects:
Orally: Fever, headache, upset stomach, and vomiting.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.

Gastrointestinal ...Orally, wild yam can cause upset stomach and vomiting, especially at higher doses (12,86450).

Hematologic ...In one case report, a 55-year-old female with protein S deficiency and systemic lupus erythematosus (SLE) had temporary vision loss in the left eye from hemiretinal vein thrombosis 3 days after taking a combination phytoestrogen product containing wild yam 276 mg, dong quai 100 mg, red clover 250 mg, and black cohosh 250 mg (13155). It is unclear if wild yam contributed to this event.

Immunologic ...There are three case reports of anaphylaxis after ingestion of cooked wild yam (96722).

Neurologic/CNS ...Orally, wild yam can cause headache and fever, especially at higher doses (86450).
