AMERICAN GINSENG (Panax quinquefolium)

POSSIBLY EFFECTIVE

Upper respiratory tract infection (URTI). Oral American ginseng seems to prevent the incidence of URTIs in some people. Details: Some evidence shows that taking a specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences) 200-400 mg twice daily over a 3-64 month period during influenza season might modestly decrease the risk of developing symptoms of a URTI such as the common cold or flu in adults (11351,13192,14345,91275). This extract also seems to reduce symptom severity and duration of symptoms when infections do occur (13192,14345,91275). The extract might not reduce the chance of getting the first cold of a season, but it seems to reduce the risk of getting repeat colds in a season (13192). Additional evidence shows that, in people aged 65 years and older, treatment with the extract for 3-4 months, in addition to influenza vaccination at 4 weeks, is necessary before there is any significant reduction in the risk of developing a respiratory tract infection (14345). One small clinical study shows that taking the extract 200 mg twice daily orally over a 12-week period during influenza season reduces the risk of laboratory confirmed influenza or influenza and respiratory syncytial virus (RSV) infections. However, it does not seem to reduce the appearance of influenza symptoms, symptom severity, or symptom duration in these patients (11351). This same extract does not appear to prevent respiratory infections in patients who are immunocompromised. In one clinical trial, taking this extract 200 mg twice daily for 3 months did not reduce the risk of developing an acute respiratory infection, the number of days of cold symptoms, or the need for use of antibiotics when compared with placebo in patients with chronic lymphocytic leukemia (29998). Preliminary clinical research in children 3-12 years of age shows that taking the same extract 13-26 mg/kg once on the day of URTI onset, then 8.5-17 mg/kg once on the next day, then 4.5-9 mg/kg once on day three does not reduce the severity or duration of symptoms when compared with placebo. However, this study was designed to evaluate the safety and tolerability of this extract in children; therefore, it was not adequately powered to evaluate effectiveness (22365).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Anemia of chronic disease. Although there has been interest in using oral American ginseng for anemia of chronic disease, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
Antiretroviral-induced insulin resistance. It is unclear if oral American ginseng is beneficial for antiretroviral-induced insulin resistance. Details: Preliminary clinical research in healthy volunteers shows that taking capsules containing ground American ginseng root 1 gram three times daily for 14 days along with the HIV protease inhibitor indinavir does not reduce indinavir-induced insulin resistance when compared to baseline (89401).
Athletic performance. Early research shows that oral American ginseng does not seem to be beneficial for athletic performance. Details: Preliminary clinical research shows that taking American ginseng extract 8 mg/kg or 16 mg/kg daily (average daily dose 618-1235 mg) for one week does not improve exertion, time to exhaustion, heart rate, or maximal oxygen consumption during bicycle testing when compared with placebo (4236). Other preliminary clinical research in physically active male college students shows that taking American ginseng 1600 mg daily for 4 weeks does not enhance workout capacity when compared with placebo (14804).
Attention deficit-hyperactivity disorder (ADHD). Oral American ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific combination product (AD-fX, Afexa Life Sciences) containing American ginseng extract plus ginkgo leaf extract may modestly improve ADHD symptoms such as anxiety, hyperactivity, and impulsivity in children aged 3-17 years when compared with baseline (8235). It is not clear if this effect is due to American ginseng, ginkgo, or the combination. Additionally, the validity of this finding is limited by the lack of a comparator group.
Breast cancer. It is unclear if oral American ginseng is beneficial for breast cancer survival. Details: Population research in China suggests that breast cancer patients who regularly take any form of ginseng, including either American ginseng or Panax ginseng, have higher quality of life scores and have a lower risk of overall mortality, breast cancer-related mortality, and breast cancer recurrence compared to patients who do not take ginseng (14466). However, ginseng users were also significantly more likely to have been treated with tamoxifen.
Cancer-related fatigue. Evidence for the use of oral American ginseng for cancer-related fatigue is conflicting. Details: Two clinical trials show that taking American ginseng 750-2000 mg in 1-2 divided doses daily for 8 weeks does not reduce cancer-related fatigue when compared with placebo (22370,104131). However, another clinical trial shows that taking American ginseng 2000 mg in two divided doses daily for 8 weeks reduces cancer-related fatigue scores by 51% after 8 weeks, compared to only 25% in those taking placebo (29996). These differing findings may be due to the instrument used to measure fatigue. The initial studies used the Brief Fatigue Inventory, whereas the positive study used the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). Additionally, treatment for a shorter duration of only 4 weeks does not appear to be effective (22370,29996,104131).
Cardiovascular disease (CVD). Although there has been interest in using oral American ginseng for CVD, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
Cognitive function. It is unclear if oral American ginseng is beneficial for cognitive function. Details: Clinical research shows that a single dose of a specific American ginseng extract (Cereboost, Naturex) 100-400 mg, taken 1-6 hours prior to cognitive testing, improves short-term working memory performance and may improve reaction time accuracy when compared with placebo in healthy young adults (22367). Other clinical research in healthy adults shows that taking the same specific American ginseng extract, standardized to contain 10% to 12% ginsenosides, as 200 mg orally daily for 14 days modestly improves memory and mental fatigue scores when compared with placebo (109518). American ginseng has also been studied in combination with other ingredients. Taking a single dose of a product containing American ginseng (Cereboost) 100 mg, bacopa 300 mg, and coffee fruit extract 100 mg modestly improves some, but not all, measures of working memory and attention after 45 minutes when compared with placebo (103375).
Diabetes. It is unclear if oral American ginseng is beneficial for diabetes. Details: Two small clinical trials show that taking American ginseng 3 grams orally, up to two hours before a meal, can significantly reduce postprandial glucose levels in patients with type 2 diabetes when compared with placebo (1018,6461). However, doses greater than 3 grams do not seem to offer any additional benefit (6461). In addition, the postprandial glucose lowering effect of American ginseng may differ among preparations due to variations in the concentration of ginsenosides (9732). American ginseng has also been studied in combination with other ingredients. Clinical research in patients with type 2 diabetes shows that taking American ginseng 1500 mg and Panax ginseng 750 mg, enriched to contain 30% total ginsenosides, orally daily for 12 weeks reduces glycated hemoglobin by 0.35% when compared with placebo. Taking this combination also reduces systolic, but not diastolic, blood pressure by about 4 mmHg when compared with placebo (107745). It is unclear if this effect is due American ginseng, Panax ginseng, or the combination.
Epilepsy. Although there has been interest in using oral American ginseng for epilepsy, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
Headache. Although there has been interest in using oral American ginseng for headaches, there is insufficient reliable information about the clinical effects of American ginseng for this purpose.
HIV/AIDS. Although there has been interest in using oral American ginseng for HIV/AIDS, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
Hypertension. Evidence on the use of oral American ginseng for hypertension is conflicting. Details: Some clinical research shows that taking American ginseng 1500 mg twice daily for 12 weeks does not reduce blood pressure when compared with placebo in patients with hypertension (22368,22369). However, other clinical research shows that taking American ginseng extract 1000 mg three times daily for 12 weeks lowers systolic blood pressure by 12% when compared with baseline in patients with type 2 diabetes and hypertension (29999). In a similar study in patients with type 2 diabetes and hypertension, American ginseng extract 500 mg in combination with Panax ginseng extract 250 mg three times daily for 12 weeks, providing 30% total ginsenosides daily, reduces central systolic blood pressure by about 5 mmHg, but not diastolic blood pressure, when compared with placebo (103046). These differing results may be due to the higher amount of total ginsenosides provided in the latter study.
Menopausal symptoms. Oral American ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research during pre- and post-menopause shows that taking a specific combination product (Phyto-Female Complex, SupHerb) containing black cohosh root extract 100 mg, dong quai root extract 75 mg, milk thistle extract 75 mg, red clover flower extract 50 mg, American ginseng root extract 50 mg, and vitex agnus-castus fruit extract 50 mg twice daily for 12 weeks improves sleep quality and reduces menopausal symptoms, including the number and intensity of hot flashes and the number of night sweats, when compared with placebo (19552). However, it is unclear whether these effects are due to American ginseng, other ingredients, or the combination.
Schizophrenia. It is unclear if oral American ginseng is beneficial for schizophrenia. Details: Preliminary clinical research in adults with schizophrenia who are taking antipsychotics shows that taking a specific American ginseng extract (HT1001, Afexa Life Sciences) 100 mg twice daily for 4 weeks modestly increases visual working memory score when compared with placebo. This treatment also reduces physical symptoms associated with antipsychotic use, such as abnormal gait or muscle rigidity. However, it does not appear to improve other clinical symptoms or parameters related to cognitive function, such as verbal working memory, sustained attention, verbal function, or immediate or delayed auditory memory, when compared with placebo (29997).
Ulcerative colitis. Although there has been interest in using oral American ginseng for ulcerative colitis, there is insufficient reliable information about the clinical effects of American ginseng for this condition. More evidence is needed to rate American ginseng for these uses.

ASHWAGANDHA (Withania somnifera)

POSSIBLY EFFECTIVE

Generalized anxiety disorder (GAD). Oral ashwagandha may modestly improve symptoms of anxiety in patients with GAD. Details: Clinical practice guidelines from the World Federation of Societies of Biological Psychiatry (WFSBP) and the Canadian Network for Mood and Anxiety Treatments (CANMAT) provisionally recommend ashwagandha root extract at doses of 300-600 mg, standardized to 5% withanolides, daily as monotherapy or adjunctive therapy in patients with GAD. This recommendation is based on a review of three preliminary clinical trials with consistent results (110318). Two of these studies are described below. A small clinical trial in patients with GAD who are taking selective serotonin reuptake inhibitors (SSRIs) shows that taking ashwagandha 1 gram daily for 6 weeks reduces symptoms of anxiety by 48%, compared with a 27% reduction in patients taking placebo. Furthermore, by the end of treatment, 72% of patients taking ashwagandha were determined to have mild symptoms of GAD, compared with only 32% of those taking placebo (102687). Another preliminary clinical trial in patients aged 16 years and older with GAD shows that taking ashwagandha root powder granules 4 grams three times daily for 60 days moderately improves anxious mood in 58% of patients, compared with no moderate improvement in the placebo group. Mild improvement occurred in 82% of patients in the placebo group and 40% of patients in the ashwagandha group (90654).
Insomnia. Oral ashwagandha may modestly improve sleep in patients with insomnia or non-restorative sleep. Details: A small meta-analysis in patients with insomnia and healthy patients shows that taking a specific ashwagandha root extract (KSM-66, Ixoreal Biomed) 250-600 mg daily or a specific root and leaf extract (Shoden, Arjuna Natural) 120 mg daily for 6-12 weeks modestly improves overall sleep, as well as sleep quality, sleep latency, total sleep time, wake time after sleep onset, and sleep efficiency, when compared with placebo. Effects were more pronounced in those with insomnia, with doses of at least 600 mg daily, and with treatment durations of at least 8 weeks (106784). These findings may be limited by heterogeneity of the included studies. In patients with non-restorative sleep, clinical research shows that taking a specific ashwagandha extract (Shoden, Arjuna Natural Private Ltd) 125 mg daily for 6 weeks increases sleep quality by 72%, compared with an improvement of 29% in patients taking placebo. Small to moderate improvements also occurred in total sleep time, sleep latency, and number of times awake (103476).
Stress. Oral ashwagandha seems to help reduce stress and may also reduce stress-related weight gain. Details: A meta-analysis of seven small clinical studies in healthy adults, patients with chronic stress, or patients with psychiatric conditions shows that taking ashwagandha 240-1000 mg daily for 8-12 weeks improves stress when compared with placebo (109587). Clinical studies included in this meta-analysis that evaluated adults with chronic stress show that taking specific ashwagandha root extracts 240 mg daily (Shoden, Arjuna Natural Ltd.) or 300 mg twice daily (KSM-66, Ixoreal Biomed) for 60 days reduces perceived stress levels by 30% to 44% and decreases cortisol levels by 22% to 28% when compared with baseline. These improvements remain significant when compared with the changes seen for patients treated with placebo (90652,95617,101816,102682). In adults reporting moderate to high stress levels, clinical research shows that treatment with specific slow-release capsules containing another ashwagandha root extract (Prolanza), 300 mg daily for 90 days, lowers perceived stress scores and cortisol levels when compared with placebo (107371). In healthy college students, clinical research also shows that taking ashwagandha root extract 350 mg twice daily for 30 days improves qualitative perceptions of stress management, but not stress scores, when compared with placebo (109589,109590). Other clinical research shows that taking ashwagandha root extract 500 mg twice daily may prevent stress-related weight gain when compared with placebo (95617).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Aging. A small clinical study suggests that oral ashwagandha may modestly improve well-being, sleep, and alertness in elderly patients. Details: A small clinical trial in individuals aged 65-80 years shows that taking ashwagandha root extract (KSM-66, Ixoreal Biomed) 600 mg daily for 12 weeks improves overall well-being, sleep quality, and mental alertness by small to moderate amounts when compared with placebo (102684).
Antipsychotic-induced metabolic side effects. It is unclear if ashwagandha is beneficial for attenuating the metabolic side effects of antipsychotic agents. Details: One preliminary clinical trial shows that taking a specific ashwagandha extract (Cap Strelaxin, M/s Pharmanza Herbal Pvt. Ltd.) 400 mg three times daily for one month reduces serum triglycerides by 12% and fasting blood glucose by 15% when compared with baseline levels. Patients were taking atypical antipsychotics and had modestly elevated triglycerides and fasting blood glucose levels at baseline (90649). The validity of these findings is limited by the lack of a comparator group.
Anxiety. It is unclear if oral ashwagandha is beneficial for reducing anxiety. Details: One small clinical study shows that taking ashwagandha root (Swiss Herbals) 300 mg twice daily for 12 weeks, in combination with standard psychotherapy interventions, including dietary counseling, deep breathing exercise instruction, and a multivitamin, reduces anxiety scores when compared with standard psychotherapy interventions and placebo (19271). However, other clinical research in young adults shows that a specific ashwagandha root and leaf extract (NooGandha, Specnova LLC) 225 mg or 400 mg daily for 30 days produces similar improvements in self-reported anxiety, stress, and depression scores when compared with placebo (107370).
Asthma. Although there has been interest in using oral ashwagandha for asthma, there is insufficient reliable information about the clinical effects of ashwagandha for this condition.
Athletic performance. It is unclear if ashwagandha is beneficial for improving athletic performance. Details: A meta-analysis of four small clinical trials shows that taking ashwagandha increases aerobic capacity in athletes and non-athletes based on the measurement of maximum oxygen consumption. Effective doses ranged from 500-1000 mg daily for up to 12 weeks (102683). Another meta-analysis shows that taking ashwagandha in doses of 120-1250 mg daily, as a single dose or divided twice daily, for up to 6 months seems to improve muscle strength, speed, time to exhaustion, recovery time, and cardiorespiratory fitness in athletes and non-athletes (105824). However, the validity of this analysis is reduced by the lack of a control group, the varied training levels of the subjects, and the wide range of outcomes assessed. More research is needed to determine whether taking ashwagandha can improve athletic performance.
Attention deficit-hyperactivity disorder (ADHD). Oral ashwagandha has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In a preliminary clinical trial, children with ADHD were given a combination herbal extract formula (Nurture & Clarity), containing ashwagandha, white peony root, gotu kola, blue-green algae, bacopa, and sage, 3 mL three times daily for 4 months. Measures of attention, cognition, and impulse control improved significantly in children receiving ashwagandha when compared with placebo (19272). The dose of ashwagandha in the combination product was not reported, and the effect of ashwagandha alone in ADHD is unclear.
Back pain. Although there has been interest in using oral or topical ashwagandha for back pain, there is insufficient reliable information about the clinical effects of ashwagandha for this condition.
Bipolar disorder. It is unclear if oral ashwagandha is beneficial for improving cognitive function in adults with bipolar disorder. Details: Clinical research shows that taking ashwagandha extract (Sensoril, Natreon, Inc.) 250 mg daily for 1 week and then 250 mg twice daily for 7 weeks, improves some, but not all, measures of cognition by a small-to-moderate amount when compared with placebo (90653).
Bronchitis. Although there has been interest in using oral ashwagandha for bronchitis, there is insufficient reliable information about the clinical effects of ashwagandha for this condition.
Cerebellar ataxia. It is unclear if oral ashwagandha is beneficial for improving balance in patients with cerebellar ataxia. Details: A small, open-label study evaluating ashwagandha 500 mg three times daily in combination with Ayurvedic therapy for one month showed improvement in balance indices in subjects with cerebellar ataxia when compared with baseline (19273). The validity of this finding is limited by the lack of a comparator group. Additionally, it is unclear if this effect is due to ashwagandha, other ingredients, or the combination.
Chemotherapy-related fatigue. Evidence is limited to one small clinical study in patients with breast cancer. Details: In preliminary clinical research in patients with breast cancer, taking ashwagandha powdered root extract 2 grams (Himalaya Drug Co) three times daily through six cycles of chemotherapy decreases chemotherapy-related fatigue when compared with no treatment. Fatigue scores were 16% to 52% higher in the control group when compared to the ashwagandha group (90651).
Chronic obstructive pulmonary disease (COPD). It is unclear if oral ashwagandha is beneficial in patients with COPD. Details: A small clinical study in patients with stable COPD shows that taking ashwagandha root extract 250 mg twice daily for 12 weeks, along with conventional therapy, improves measures of lung function and exercise tolerance, but not quality of life, when compared with conventional therapy alone (109588).
Cognitive function. Although there has been interest in using oral ashwagandha for cognitive function, there is insufficient reliable information about the clinical effects of ashwagandha for this condition.
Constipation. Oral ashwagandha has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A very small clinical study in adults with constipation shows that taking a combination product containing ashwagandha root and ambrette fruit extracts 300 mg or 500 mg daily for 14 days improves bowel movement frequency and abdominal, rectal, and stool symptoms when compared with placebo (112114). It is unclear if these effects are due to ashwagandha, ambrette, or the combination. The validity of these effects is limited by the small sample size.
Coronavirus disease 2019 (COVID-19). Oral ashwagandha has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults hospitalized with COVID-19 shows that taking a specific combination product, (Artovid-20, Bioved Pharmaceuticals) containing ashwagandha, ginger, turmeric, and Boswellia, 1,776 mg orally twice daily for 14 days shortens the duration of symptoms by 0.9 days when compared with placebo. Taking the combination product also modestly reduced the severity ratings of some symptoms, such as sore throat and cough, however, these improvements are unlikely to be clinically relevant (109899). Another small clinical study in adults with mild to moderate COVID-19 shows that taking ashwagandha 500 mg and ginger 1000 mg twice daily for 15 days reduces time to recovery by around 6 days and increases the rate of clinical cure 14-fold and 2.6-fold at days 5 and 7, respectively, when compared with a control. However, taking this combination does not appear to improve the proportion of patients with a negative COVID-19 test, viral clearance, serum antibodies, chest findings, or disease progression when compared with control (112094). The validity of these findings is limited by a lack of blinding, and the study may have been inadequately powered to detect a difference between groups. Additionally, it is unclear if these effects are due to ashwagandha, ginger, or the combination.
Diabetes. It is unclear if oral ashwagandha is beneficial for type 2 diabetes. Details: In patients with type 2 diabetes, preliminary clinical research shows that ashwagandha 3 grams daily for 30 days decreases blood glucose to a degree similar to oral hypoglycemic drugs (19274). However, this study did not compare ashwagandha directly to a group taking oral hypoglycemic drugs.
Fibromyalgia. Although there has been interest in using oral ashwagandha for fibromyalgia, there is insufficient reliable information about the clinical effects of ashwagandha for this condition.
Hiccups. Although there has been interest in using oral ashwagandha for hiccups, there is insufficient reliable information about the clinical effects of ashwagandha for this condition.
Hypercholesterolemia. It is unclear if ashwagandha is beneficial for hypercholesterolemia. Details: A very small clinical study in subjects with hypercholesterolemia shows that ashwagandha 3 grams daily for 30 days decreases serum cholesterol, triglyceride, low-density lipoprotein (LDL) cholesterol, and very low-density lipoprotein (VLDL) cholesterol levels when compared with baseline (19274). The validity of these findings is limited by the lack of a comparator group.
Hypothyroidism. It is unclear if ashwagandha is beneficial for hypothyroidism. Details: Preliminary clinical research in adults with subclinical hypothyroidism shows that taking a specific ashwagandha root extract (KSM-66, Ixoreal Biomed) 300 mg twice daily for 8 weeks increases triiodothyronine (T3) and thyroxine (T4) levels by 42% and 20%, respectively, and reduces serum TSH levels by 17% from baseline. These changes are significant when compared with placebo (97292). However, the effects of ashwagandha on thyroid hormone levels in patients with overt hypothyroidism, or in patients taking prescription thyroid hormones, is unknown.
Infertility. Although there has been interest in using oral ashwagandha for infertility in females, there is insufficient reliable information about the clinical effects of ashwagandha for this condition.
Male infertility. It is unclear if oral ashwagandha is beneficial for male infertility. Details: Preliminary clinical research in males with infertility shows that taking ashwagandha root powder for approximately 3 months modestly improves hormone levels, as well as sperm count and motility, when compared with baseline (19275,90650). The validity of these findings is limited by the lack of a comparator group. One study used a specific ashwagandha root extract (KSM-66 Ashwagandha, Ixoreal Biomed) 225 mg three times daily; another study provided doses of 5 grams daily (19275,90650).
Menopausal symptoms. Oral ashwagandha may be beneficial for menopausal symptoms. Details: A small clinical study in healthy adults in perimenopause shows that taking a specific ashwagandha root extract (KSM-66, Ixoreal Biomed) 300 mg twice daily for 8 weeks improves menopausal symptom severity by 24%, compared with 11% in those receiving placebo. Quality of life and hot flashes also were improved in those taking ashwagandha (106785).
Obsessive-compulsive disorder (OCD). It is unclear if ashwagandha is beneficial for OCD. Details: Preliminary clinical research shows that taking ashwagandha root extract 120 mg after meals for 6 weeks, in conjunction with prescribed selective-serotonin reuptake inhibitors (SSRIs), might reduce OCD symptom severity when compared with prescribed SSRIs alone. The dose was initiated at 30 mg daily and increased by 30 mg every 4 days. Although OCD scores were significantly reduced when compared with placebo, it should be noted that scores were already significantly lower in the placebo group at baseline (95618).
Osteoarthritis. Oral ashwagandha has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In patients with osteoarthritis, taking a specific combination supplement, containing ashwagandha 450 mg, Ayurvedic zinc complex 50 mg, guggul 100 mg, and turmeric 50 mg (Articulin-F) two capsules three times daily for 3 months reduces symptoms of pain and swelling when compared with placebo. However, there were no radiological improvements (19276). It is unclear if this effect is due to ashwagandha, other ingredients, or the combination.
Parkinson disease. Oral ashwagandha has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In patients with Parkinson disease, a small clinical study shows that taking a product containing ashwagandha 14.5 grams, cowhage 4.5 grams, Hyoscyamus reticulantus 0.75 grams, and Sida cordifolia 14.5 grams in lukewarm milk twice daily for 56 days improves symptoms like tremor, stiffness, and cramps when compared with baseline. The therapy followed 28 days of cleansing or eliminative therapy using Ayurvedic remedies (6899). The validity of these findings is limited by the lack of a comparator group. Also, it is unclear if these effects are due to ashwagandha, other ingredients, or the combination. Cowhage contains levodopa, which may contribute to any benefit seen with this combination product.
Psychological well-being. It is unclear if oral ashwagandha is beneficial for improving psychological well-being in college students. Details: A small clinical study in healthy college students shows that taking ashwagandha root extract 350 mg twice daily for 30 days improves perceptions of well-being, including improvements in energy, mental clarity, food cravings, and sleep quality, when compared with placebo. Qualitative analysis also suggests these students had improvements in stress management, but stress scores were not reduced when compared with placebo (109589,109590).
Rheumatoid arthritis (RA). It is unclear if ashwagandha is beneficial for improving symptoms of RA. Details: Preliminary clinical research shows that taking ashwagandha powder 5 grams twice daily for 3 weeks, followed by 4 weeks of sidh makardhwaj (a mixture of gold, mercury, and sulfur) 100 mg with honey daily, modestly improves symptoms in about 50% of males and 60% of females with RA when compared with baseline (95620). The lack of a control group limits the validity of this finding. Additionally, the effect of ashwagandha powder alone is unclear.
Sexual dysfunction. Small clinical studies suggest that oral ashwagandha root extract may help improve sexual arousal and sexual desire in some females and males with sexual dysfunction. Details: Two, small clinical studies in adult females with sexual dysfunction show that taking ashwagandha root extract (KSM-66, Ixoreal Biomed) 300 mg twice daily with food for 8 weeks in conjunction with or without counseling increases the number of successful sexual encounters and improves orgasms, satisfaction, lubrication, and arousal when compared with placebo or counseling alone (95619,110492). Also, a small clinical study in adult males with low sexual desire shows that taking the same ashwagandha root extract 300 mg twice daily after meals for 8 weeks improves subjective sexual functioning scores, including measures of sexual arousal, sexual desire, sexual behavior, and orgasm, when compared with placebo (109586).
Smoking cessation. Oral ashwagandha has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-sized clinical study in adults with a history of smoking 5 or more cigarettes daily for at least 3 years shows that taking a specific combination product containing ashwagandha 100 mg, Indian gooseberry, tribulus, bacopa, Albizia lebbeck, licorice, clove, ginger, cowhage, holy basil, and turmeric (Smotect, Smotect India) daily for 3 months reduces the number of cigarettes smoked daily and levels of alveolar carbon monoxide and carboxyhemoglobin but does not improve lung capacity when compared with placebo (112115). It is unclear if these effects are due to ashwagandha, other ingredients, or the combination.
Tuberculosis. Although there has been interest in using oral ashwagandha for tuberculosis, there is insufficient reliable information about the clinical effects of ashwagandha for this condition.
Vitiligo. Although there has been interest in using oral ashwagandha for vitiligo, there is insufficient reliable information about the clinical effects of ashwagandha for this condition.
Wrinkled skin. It is unclear if topical ashwagandha is beneficial in individuals with wrinkled skin. Details: A small clinical study in healthy adults with photoaged skin shows that applying ashwagandha root extract 8% lotion daily for 60 days improves physician-rated scores for skin wrinkles, hydration, brightness, tone, and pigmentation and improves other measures of skin elasticity and hydration when compared with placebo. However, changes in melanin content did not differ between treatment groups (111538).
Wound healing. Although there has been interest in using topical ashwagandha for healing of skin ulcers and skin sores, there is insufficient reliable information about the clinical effects of ashwagandha for this condition. More evidence is needed to rate ashwagandha for these uses.

ELEUTHERO (Eleutherococcus senticosus)

POSSIBLY EFFECTIVE

Genital herpes. Oral eleuthero root extract might help to prevent and reduce the severity of genital herpes outbreaks. Details: One clinical study in patients with recurrent genital herpes infections shows that taking a specific eleuthero root extract (Elagen) 400 mg, standardized to contain eleutheroside 0.3%, daily for at least 3 months reduces the frequency, severity, and duration of outbreaks when compared with placebo (730).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Athletic performance. Small clinical studies suggest that oral eleuthero root is not beneficial for improving athletic performance. Details: One study in trained distance runners shows that a specific eleuthero root liquid extract, standardized to eleutherosides B and E content, taken as 3.4 mL daily for 6 weeks, does not affect endurance, performance, or psychological, cardiac, or respiratory parameters when compared with placebo (7522). Small studies in trained athletes or healthy adults show that taking eleuthero 800-1200 mg daily (Endurox) for 1-6 weeks does not seem to have any effect on cycling performance time, respiration, lactate production, or heart rate recovery during cycling, stair-stepping exercise, treadmill, or cyclic ergometry when compared with placebo (2335,7600,7601,8994). However, there has been some speculation that a longer duration of supplementation is needed for benefit. One study in recreationally trained athletes shows that taking a specific powdered eleuthero root product 400 mg twice daily for 8 weeks increased cycling endurance time by 23% and maximal oxygen consumption by 12% when compared with placebo. This product was standardized to contain eleutheroside B 0.11% and eleutheroside E 0.12% (17186).
Bipolar disorder. It is unclear if oral eleuthero root is beneficial for bipolar disorder. Details: A small clinical study in Chinese adolescents ages 12-17 years with bipolar disorder shows that taking eleuthero root 750 mg orally three times daily, in conjunction with lithium for 6 weeks, induces similar response rates and remission rates when compared with lithium plus fluoxetine 20 mg (75028). It is not clear how this response rate compares to the use of lithium alone.
Cardiovascular disease (CVD). It is unclear if oral eleuthero fruit is beneficial for preventing the development of CVD. Details: One small clinical study in healthy adults with at least two cardiovascular risk factors shows that taking an aqueous extract of eleuthero fruit 500 mg daily for 12 weeks seems to modestly reduce systolic blood pressure and arterial stiffness, as measured by brachial-ankle pulse wave velocity, when compared with placebo. It did not affect diastolic blood pressure, flow-mediated dilation, or carotid intima-media thickness. Also, taking a higher 1000 mg dose of the same eleuthero extract daily did not have significant effects on any measured parameters (105025).
Chronic fatigue syndrome (CFS). It is unclear if oral eleuthero root is beneficial for CFS. Details: One clinical study in adults with CFS shows that taking eleuthero root extract 2 grams daily for 2 months improves fatigue severity and duration when compared with baseline, but not when compared with placebo (11099).
Cognitive function. It is unclear if oral eleuthero is beneficial for cognitive function. Details: A very small clinical study in middle-aged people shows that taking eleuthero 325 mg twice daily might improve selective memory when compared with placebo (2574). Another very small study in healthy adults shows that taking a combination product containing extracts of eleuthero leaf 203 mg and Drynaria fortunei 20 mg daily for 12 weeks improves figure recall, but not immediate memory or attention, when compared with placebo (102316). It is unclear if this effect is due to eleuthero, Drynaria fortunei, or the combination.
Common cold. Oral eleuthero has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some clinical research shows that taking capsules of a specific combination product containing eleuthero plus andrographis (Kan Jang, Swedish Herbal Institute) orally improves symptoms of the common cold when started within 72 hours of symptom onset. Some symptoms can improve after 2 days of treatment; however, it typically takes 4-5 days of treatment for maximal symptom relief (5784,10795,12380). Some research shows the combination of eleuthero and andrographis relieves cold symptoms better than echinacea or placebo in children (12381). It is unclear if this effect is due to eleuthero, andrographis, or the combination.
Diabetes. It is unclear if oral eleuthero is beneficial for improving glycemic control in type 2 diabetes. Details: One small clinical study in adults with type 2 diabetes shows that taking a specific eleuthero extract, standardized to contain eleutherosides E and B 1.12%, as 480 mg daily for 3 months, decreases fasting glucose by a mean of 36 mg/dL, postprandial blood glucose by a mean of 35 mg/dL, glycated hemoglobin (HbA1c) by a mean of 0.8%, triglycerides by a mean of 106 mg/dL, and total cholesterol by a mean of 21 mg/dL when compared with placebo (91509).
Diabetic neuropathy. It is unclear if oral eleuthero is beneficial for diabetic neuropathy. Details: One small clinical study in adults with type 2 diabetes shows that taking a specific eleuthero extract, standardized to contain eleutherosides E and B 1.12%, as 480 mg daily for 3 months, modestly improves subjective symptoms of diabetic neuropathy when compared with placebo (91509).
Familial Mediterranean fever. Oral eleuthero has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study in children ages 3-15 years with familial Mediterranean fever shows that taking a specific combination product (ImmunoGuard, Inspired Nutritionals) containing eleuthero, andrographis, schisandra, and licorice for one month reduces the duration, frequency, and severity of disease recurrence when compared with placebo (12382). It is unclear if this effect is due to eleuthero, other ingredients, or the combination.
Fibromyalgia. Although there is interest in using oral eleuthero for fibromyalgia, there is insufficient reliable information about the clinical effects of eleuthero for this condition.
Hangover. It is unclear if oral eleuthero root is beneficial for hangovers. Details: One small clinical study in healthy males shows that consuming one bottle of a powdered polysaccharide-rich extract of eleuthero root before and after consuming alcohol modestly reduces the severity of hangover as measured by the Acute Hangover Scale questionnaire score when compared with placebo (91508). However, the validity of these findings is brought into question due to the incomplete study information provided.
Influenza. Oral eleuthero has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with influenza shows that taking a specific combination product containing eleuthero 20-30 mg plus andrographis 178-266 mg (Kan Jang, Swedish Herbal Institute) three times daily for 3-5 days relieves symptoms more quickly than amantadine. This combination product also reduced the risk of post-influenza complications, such as sinusitis or bronchitis, when compared with amantadine (10441). It is unclear if these effects are due to eleuthero, andrographis, or the combination.
Osteoarthritis. Oral eleuthero has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking two capsules each containing 400 mg of a combination of eleuthero, Panax pseudoginseng, and rehmannia daily for 6 weeks improves physical function in individuals with knee osteoarthritis when compared with placebo. However, the combination does not seem to reduce pain or stiffness when compared with placebo (74950). It is unclear if this effect is due to eleuthero, other ingredients, or the combination.
Osteoporosis. Oral eleuthero has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A very small clinical study in postmenopausal patients shows that taking low-dose calcium and vitamin D3 in combination with a 250 mg blend of rehmannia root and eleuthero stem bark extracts twice daily for 12 months attenuates the loss of spine and femur bone mineral density when compared with placebo or high-dose calcium and vitamin D (75036). It is unclear if this effect is due to eleuthero, rehmannia, or the combination.
Pneumonia. Oral eleuthero has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with acute, nonspecific pneumonia shows that taking a specific combination product (ADAPT-232), containing eleuthero, rhodiola, and schisandra, as 20 mL twice daily for 10-15 days in conjunction with conventional treatment, reduces the duration of antibiotic treatment and improves quality of life when compared with conventional treatment alone (71152).
Quality of life. It is unclear if oral eleuthero root improves quality of life in older healthy adults. Details: A small clinical study in elderly volunteers shows that taking eleuthero 300 mg daily improves social functioning and mental well-being after 4 weeks of treatment when compared with placebo. However, this improvement was not maintained after 8 weeks of treatment (15586).
Rheumatoid arthritis (RA). Although there is interest in using oral eleuthero for RA, there is insufficient reliable information about the clinical effects of eleuthero for this condition.
Stress. It is unclear if oral eleuthero root is beneficial for stress. Details: One clinical study in adults 30-50 years of age with symptoms of stress shows that taking a specific eleuthero root extract (WS 1070) 120 mg daily for 8 weeks does not improve fatigue, exhaustion, cognitive alertness, or measures of stress when taken alone or in conjunction with stress management training (91510). However, another small clinical study in healthy females 20-68 years of age who have experienced stress for a prolonged period of time shows that taking a single, 270 mg dose of a combination agent (ADAPT-232) containing eleuthero, rhodiola, and schisandra improves attention and cognitive speed and accuracy when compared with placebo (19289). It is unclear if these effects are due to eleuthero, other ingredients, or the combination.
Upper respiratory tract infection (URTI). Oral eleuthero has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in adults with an uncomplicated URTI shows that taking 30 mL of a combination product (Kan Jang, Swedish Herbal Institute) containing extracts of eleuthero root (eleutherosides B and E 0.03 mg/mL), echinacea root, and malabar nut leaf daily does not reduce the severity or frequency of cough by a clinically meaningful amount after 3-4 days of treatment when compared with bromhexine hydrochloride or placebo (95648). However, a non-blinded clinical study shows that taking 30 mL of this same product three times daily for 6 days improves the severity and frequency of coughing and the degree of nasal congestion when compared with bromohexine. Additionally, patients taking the combination product recovered two days sooner, on average, than those taking bromohexine (48569). The reason for these conflicting findings is unclear but may be due to an inadequate duration of treatment in the first study and/or lack of blinding in the second study. Also, it is unclear if any benefit is due to eleuthero, other ingredients, or the combination. Other research has evaluated a capsule formulation of Kan Jang (Swedish Herbal Institute), with each capsule containing eleuthero root 11.4 mg and andrographis 195 mg. One small clinical study in patients with an uncomplicated URTI shows that taking this product as two capsules three times daily for 5 days reduces the median number of sick leave days to 2 days, compared with 3 days in the placebo group. It also increases the total number of recovered patients on day 3 to 75%, compared with 55% of those taking placebo (107471). More evidence is needed to rate eleuthero for these uses.

PANAX GINSENG

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, 2700 mg daily in three divided doses (8813).
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 (1427,4230,4231,23646,23647,89737). 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).

INSUFFICIENT RELIABLE EVIDENCE to RATE

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.
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 with 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.
Breast cancer. It is unclear if oral Panax ginseng is beneficial in breast cancer. Details: Population research in China has found that breast cancer patients who regularly take any form of ginseng, including either Panax ginseng or American ginseng, have 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.
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.
Cognitive impairment. Oral Panax ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. 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 this benefit is due to Panax ginseng, other ingredients, or the combination.
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.
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 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. 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 no benefit with Korean red ginseng extract 3-8 grams daily for 4 weeks (17734). 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).
Hypertension. It is unclear if oral Panax ginseng is beneficial for hypertension. Details: Various forms of Panax ginseng have been evaluated in patients with mild to severe hypertension. 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 systolic blood pressure (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 systolic or diastolic blood pressure when compared with placebo (89741). Some research has also evaluated Panax ginseng in combination with American ginseng. A clinical study in patients with hypertension shows that taking Panax Ginseng and American ginseng 2.25 grams enriched to contain 30% total ginsenosides daily for 12 weeks reduces central systolic blood pressure by about 5 mmHg, but does not impact diastolic blood pressure, when compared with placebo (103046). It is unclear if these effects are due to Panax ginseng, American ginseng, or the combination. Some research has also evaluated Panax ginseng in combination with American ginseng. A clinical study in patients with hypertension (systolic blood pressure 140-160 mmHg or treated) and type 2 diabetes shows that taking Panax ginseng 0.75 grams and American ginseng 1.5 grams, enriched to contain 30% total ginsenosides, daily for 12 weeks reduces central systolic blood pressure by about 5 mmHg and 24-hour systolic blood pressure by about 4 mmHg, but does not impact diastolic blood pressure, when compared with a control of wheat-bran (103046,107745). Patients receiving this combination also have greater reductions in daytime systolic blood pressure, 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). 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 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).
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.
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). Although there has been interest in using oral Panax ginseng for RA, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
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).
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.

ELEUTHERO (Eleutherococcus senticosus)

ANTICOAGULANT/ANTIPLATELET DRUGS

Interaction Rating = Moderate Be cautious with this combination.

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

Theoretically, eleuthero may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.

Details

In vitro and animal research shows that a constituent of eleuthero, dihydroxybenzoic acid, appears to inhibit platelet aggregation (7592,74976). Concomitant use with anticoagulant or antiplatelet drugs might increase the risk of bleeding.

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

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

Theoretically, eleuthero might have additive effects when used with antidiabetes drugs.

Details

Animal research suggests that certain constituents of eleuthero have hypoglycemic activity in both healthy and diabetic animals (7591,73535,74932,74956,74988,74990). A small study in adults with type 2 diabetes also shows that taking eleuthero for 3 months can lower blood glucose levels (91509). However, one very small study in healthy individuals shows that taking powdered eleuthero 3 grams, 40 minutes prior to a 75-gram oral glucose tolerance test, significantly increases postprandial blood glucose levels when compared with placebo (12536). These contradictory findings might be due to patient-specific variability and variability in active ingredient ratios.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

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

Theoretically, eleuthero might increase levels of drugs metabolized by CYP1A2.

Details

In vitro and animal research suggest that standardized extracts of eleuthero inhibit CYP1A2 (7532). 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, eleuthero might increase levels of drugs metabolized by CYP2C9.

Details

In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP2C9 (7532). This effect has not been reported in humans.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

Interaction Rating = Minor Be watchful with this combination.

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

Theoretically, eleuthero might increase levels of drugs metabolized by CYP2D6.

Details

In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP2D6. However, research in healthy human volunteers has found that taking eleuthero 485 mg twice daily for 14 days does not inhibit CYP2D6 drug metabolism (7532,10400).

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Interaction Rating = Minor Be watchful with this combination.

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

Theoretically, eleuthero might increase levels of drugs metabolized by CYP3A4.

Details

In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP3A4. However, research in healthy human volunteers has found that taking eleuthero 485 mg twice daily for 14 days does not inhibit CYP3A4 drug metabolism (7532,10400).

DIGOXIN (Lanoxin)

Interaction Rating = Moderate Be cautious with this combination.

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

Eleuthero might increase serum digoxin levels and increase the risk of side effects.

Details

In one case report, a 74-year-old male who was stabilized on digoxin presented with an elevated serum digoxin level after starting an eleuthero supplement, without symptoms of toxicity. After stopping the supplement, serum digoxin levels returned to normal (543). It is not clear whether this was due to a pharmacokinetic interaction or to interference with the digoxin assay (15585). Although the product was found to be free of digoxin and digitoxin (543), it was not tested for other contaminants (797).

IMMUNOSUPPRESSANTS

Interaction Rating = Moderate Be cautious with this combination.

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

Theoretically, eleuthero might interfere with immunosuppressive drugs because of its immunostimulant activity.

Details

Animal and in vitro research shows that eleuthero extracts have immunomodulatory effects, including increasing cellular and humoral activity (74887,74915).

ORGANIC ANION-TRANSPORTING POLYPEPTIDE SUBSTRATES (OATP)

Interaction Rating = Minor Be watchful with this combination.

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

Theoretically, eleuthero might decrease levels of drugs metabolized by OATP.

Details

In vitro research suggests that eleuthero inhibits OATP2B1, which might reduce the bioavailability of oral drugs that are substrates of OATP2B1 (35450). Due to the weak inhibitory effect identified in this study, this interaction is not likely to be clinically significant.

P-GLYCOPROTEIN SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

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

Theoretically, eleuthero might increase levels of P-glycoprotein substrates.

Details

In vitro research suggests that eleuthero can inhibit the multi-drug transporter protein, P-glycoprotein (22639,91509). However, it is too soon to tell if this is clinically important. This interaction has not been reported in humans.

PANAX GINSENG

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.

ASHWAGANDHA (Withania somnifera)

General ...Orally, ashwagandha seems to be well-tolerated. Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Diarrhea, gastrointestinal upset, nausea, and vomiting. However, these adverse effects do not commonly occur with typical doses.
Serious Adverse Effects (Rare):
Orally: Some case reports raise concerns about acute liver failure, hepatic encephalopathy, and the need for liver transplantation with ashwagandha treatment.

Dermatologic ...Orally, dermatitis has been reported in three of 42 patients in a clinical trial (19276).

Endocrine ...A case report describes a 73-year-old female who had taken an ashwagandha root extract (unspecified dose) for 2 years to treat hypothyroidism which had been previously managed with levothyroxine. The patient was diagnosed with hyperthyroidism after presenting with supraventricular tachycardia, chest pain, tremor, dizziness, fatigue, irritability, hair thinning, and low thyroid stimulating hormone (TSH) levels. Hyperthyroidism resolved after discontinuing ashwagandha (108745).

Gastrointestinal ...Orally, large doses may cause gastrointestinal upset, diarrhea, and vomiting secondary to irritation of the mucous and serous membranes (3710). When taken orally, nausea and abdominal pain (19276,110490) and gastritis and flatulence (90651) have been reported.

Genitourinary ...In one case report, a 28-year-old male with a decrease in libido who was taking ashwagandha 5 grams daily over 10 days subsequently experienced burning, itching, and skin and mucous membrane discoloration of the penis, as well as an oval, dusky, eroded plaque (3 cm) with erythema on the glans penis and prepuce (32537).

Hepatic ...Orally, ashwagandha in doses of 154-1350 mg daily has played a role in several case reports of liver injury. In most of these cases, other causes of liver injury were excluded, and liver failure did not occur. Symptoms included jaundice, pruritus, malaise, fatigue, lethargy, weight loss, nausea, diarrhea, abdominal pain, stool discoloration, and dark urine. Symptom onset was typically 5-180 days from first intake, although in some cases onset occurred after more than 12 months of use (102686,107372,110490,110491,111533,111535,112111). Laboratory findings include elevated aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, and serum bilirubin (112111). In most cases, liver enzymes normalized within 1-5 months after discontinuation of ashwagandha (102686,107372,110491,111535,112111). However, treatment with corticosteroids, lactulose, ornithine, ursodeoxycholic acid, and plasmapheresis, among other interventions, was required in one case (111533). Rarely, use of oral ashwagandha has been reported to cause hepatic encephalopathy and liver failure requiring liver transplantation (110490).

Neurologic/CNS ...Orally, ashwagandha has been reported to cause drowsiness (110492). Headache, neck pain, and blurry vision have been reported in a 47-year-old female taking ashwagandha, cannabis, and venlafaxine. Imaging over the course of multiple years and hospital admissions indicated numerous instances of intracranial hemorrhage and multifocal stenosis of intracranial arteries, likely secondary to reversible cerebral vasoconstriction syndrome (RCVS) (112113). It is unclear whether the RCVS and subsequent intracranial hemorrhages were precipitated by ashwagandha, cannabis, or venlafaxine.

ELEUTHERO (Eleutherococcus senticosus)

General ...Orally, eleuthero root is generally well tolerated when used short-term.
Most Common Adverse Effects:
Orally: Diarrhea, dyspepsia, gastrointestinal upset, headache, nausea, and urticaria.

Cardiovascular ...Orally, increased blood pressure has been reported in children with hypotension taking eleuthero in one clinical study (74980). Eleuthero has been reported to cause tachycardia, hypertension, and pericardial pain in patients with rheumatic heart disease or atherosclerosis. It is unclear if these effects were caused by eleuthero, or by the cardioglycoside-containing herb, silk vine (Periploca sepium), which is a common adulterant found in eleuthero products (12,797,6500).

Dermatologic ...Orally, eleuthero has been reported to cause rash in some clinical studies (75013,75028).

Gastrointestinal ...Orally, eleuthero has been reported to cause dyspepsia, nausea, diarrhea, and gastrointestinal upset in some patients (74938,75028,91510).

Genitourinary ...Orally, mastalgia and uterine bleeding were reported in 7. 3% of females taking eleuthero 2 grams daily in one clinical study (6500,11099). These adverse effects seem to be more likely with higher doses.

Neurologic/CNS ...Orally, headaches have been reported in 9. 8% of people taking eleuthero in one clinical study (11099).
In one case report, a 53-year-old female developed spontaneous subarachnoid hemorrhage associated with the use of an herbal supplement containing red clover, dong quai, and eleuthero (70419). It is unclear if this event was related to the use of eleuthero, the other ingredients, the combination, or another cause entirely.

Psychiatric ...Orally, nervousness has been reported in 7. 3% of people taking eleuthero in one clinical study (11099). Eleuthero has also been reported to cause slight anxiety, irritability, and melancholy in some patients (6500,11099). These adverse effects seem to be more likely to occur with higher doses.

PANAX GINSENG

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). 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).
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), diarrhea (3353,89734,103477), abdominal pain (89734,87984), and nausea (589,87984). However, these effects are typically associated with long-term, high-dose usage (3353).

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 ...Uncommon side effects can include cholestatic hepatitis (associated with a Panax ginseng-containing, multi-ingredient product, Prostata), such as that which occurred in a 65-year old male following oral use (598).

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). Headache (594,23638), 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).
