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

• Celiac disease. Although there has been interest in using oral lipase for celiac disease, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Dyspepsia. It is unclear if oral lipase is beneficial for improving symptoms of postprandial distress syndrome. Details: A small clinical trial shows that taking a specific acid-resistant lipase (Amano Enzyme USA) 280 mg immediately before a high-fat meal does not reduce postprandial bloating and nausea when compared with placebo in individuals with postprandial distress syndrome (101900).
• Inflammatory bowel disease (IBD). Although there has been interest in using oral lipase for IBD, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Prematurity. It is unclear if adding a specific form of lipase, recombinant human bile salt-stimulated lipase (rhBSSL), to infant formula improves outcomes in premature infants. Some research suggests a potential increased risk for adverse effects. Details: Human breast milk contains rhBSSL, but it is inactivated when breast milk is pasteurized for donation. Clinical research in infants born before 32 weeks' gestation shows that adding rhBSSL as 8700 units per 100 mL formula or pasteurized breast milk, for 4 weeks does not increase growth velocity, body length, or head circumference over the next 12 months when compared with formula or pasteurized breast milk devoid of lipase. However, the infants who were small for gestational age (SGA), which made up approximately 15% of the study population, grew by an additional 1.9 grams/kg daily on average when compared with placebo (101940). More evidence is needed to rate lipase for these uses.

• Angina. Low-quality clinical research shows that oral or intravenous Panax notoginseng may improve the frequency and severity of angina symptoms. Details: Meta-analyses of low-quality clinical research in patients with angina shows that Panax notoginseng administered intravenously or orally 200-400 mg 2-3 times daily for 2-6 weeks, in addition to conventional medicine, increases the number of patients who achieve a 50% improvement in angina pectoris symptoms by approximately 1.2-fold when compared with conventional medicine alone (94321,94326,94378). Panax notoginseng also reduces angina attack frequency by about 2 attacks per week but does not reduce the incidence of intractable angina pectoris (94321).
• Intracranial hemorrhage. Low-quality clinical research shows that intravenous Panax notoginseng saponins may improve recovery and mortality in patients with intracranial hemorrhage. Details: A meta-analysis of low-quality clinical research in patients with intracranial or intracerebral hemorrhage shows that treatment with Panax notoginseng saponins 140-600 mg intravenously daily for 2-10 weeks increases the odds of improvement by 2.7-fold when compared with conventional treatment alone. A subgroup analysis also suggests that treatment within 48 hours reduces the risk of mortality by 55% when compared with conventional treatment alone (94324).
• Stroke. Low-quality clinical research in patients with ischemic stroke shows that oral or intravenous Panax notoginseng, in addition to conventional therapy, may improve recovery, as well as neurologic and functional scores. Details: Two meta-analyses of clinical research in patients with an ischemic stroke shows that treatment with Panax notoginseng, most commonly a specific product (Xuesaitong, Xing Zhong Pharmaceutical Co. Ltd.), 150-1080 mg intravenously daily for 10-42 days, increases the overall response rate and improvement rate by 20% to 21% when compared with conventional medicine alone (94373,109523). Treatment with Panax notoginseng also improved some measures of activities of daily living (109523). Preliminary clinical research in patients with a recent anterior cerebral ischemic stroke shows that taking Panax notoginseng root (sanchitongtshu) extract, containing 100 mg of panaxatriol saponins, orally three times daily with aspirin 50 mg daily for 28 days improves neurological deficit scores and activities of daily living scores when compared with placebo and aspirin (17183).

POSSIBLY INEFFECTIVE

• Myocardial infarction (MI). Low-quality clinical research shows that oral Panax notoginseng may not reduce the risk of MI in patients with coronary heart disease. Details: A meta-analysis of two small clinical trials in patients with existing coronary heart disease shows that that taking a specific Panax notoginseng product (Xuesaitong soft capsule, Shenghuo Pharmaceutical Holdings) 240 mg orally twice daily along with conventional therapy for 4 weeks does not reduce the risk of MI when compared with conventional therapy alone (94321).

• Atherosclerosis. Although there has been interest in using oral Panax notoginseng for atherosclerosis, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.
• Athletic performance. It is unclear if oral Panax notoginseng is beneficial for improving athletic performance. Details: A meta-analysis of small clinical studies in generally healthy adults shows that taking Panax notoginseng 200-1350 mg or ginsenoside Rg1, a constituent of Panax notoginseng, 5 mg orally once daily for 1-30 days before running or cycling increases exercise endurance when compared with control (109672). One clinical study of untrained adults shows that taking Panax notoginseng root powder 1350 mg daily for 30 days increases cycling endurance by at least 7 minutes when compared with baseline (94384). The validity of this study is limited by the lack of a comparator group.
• Bleeding. Although there has been interest in using oral Panax notoginseng for bleeding, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.

• Osteoarthritis. Oral Panax notoginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with knee osteoarthritis shows that taking two capsules, each containing 400 mg of a combination of Panax notoginseng, Siberian ginseng, and rehmannia, orally daily for 6 weeks moderately improves physical function scores, but not pain or stiffness scores, when compared with placebo (74950).
• Rheumatoid arthritis (RA). Although there has been interest in using oral Panax notoginseng for RA, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.
• Ulcerative colitis. Rectal Panax notoginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults admitted to the hospital with mild to moderate ulcerative colitis lesions shows that administering a suppository containing Panax notoginseng and multiple other ingredients rectally for 3 months improves diarrhea and bloody stool symptom scores when compared with placebo. Taking the combination product also reduced recurrence by 79% when compared with placebo. Patients received 2 suppositories twice daily for the first month, 1 suppository twice daily for the second month, and 1 suppository once daily for the third month. Each suppository contained Panax notoginseng 36 grams, cortex phellodendri 120 grams, radix Sanguisorbae 120 grams, arnebia root, 120 grams, radix pulsatillae 120 grams, rhizoma coptidis 120 grams, cortex fraxini 120 grams, rhizoma corydalis, pericarpium papaveris 72 grams, radix sophorae flavescentis 72 grams, and rhizoma bletillae 72 grams (109673).
• Venous thromboembolism (VTE). It is unclear if oral or intravenous Panax notoginseng is beneficial for the prevention of postoperative deep vein thrombosis (DVT). Details: A meta-analysis of randomized controlled trials in adults undergoing surgical treatment for a fracture shows that using a Panax notoginseng injection, alone or in combination with other anticoagulants, for 3-14 days reduces the risk of DVT by 58% when compared with active control, such as low-molecular weight heparin (LMWH) or rivaroxaban (105510). The validity of these findings is limited by the high heterogeneity of the included studies. A prospective study in post-surgical adults using LMWH shows that taking a specific Panax notoginseng tablet (Xuesaitong, Hunan Xiangya Pharmaceutical Company) 100 mg three times daily reduces the risk of DVT by 44% when compared with LMWH alone (109674). The validity of this study is limited by lack of randomization. More evidence is needed to rate Panax notoginseng for these uses.

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aging skin. In patients with deep wrinkles, preliminary clinical research shows that taking zinc citrate 50 mg and phytase 3,000 units daily for four days prior to a botulinum toxin treatment increases the patient-reported duration of botulinum toxin effects by approximately 25%, compared with no improvement in patients taking zinc gluconate 10 mg or placebo. The efficacy of botulinum treatment was also improved (101913). Whether this reported benefit is due to the dose or form of zinc, citrate, phytase, the combination, or other factors, is unclear (101913,101914).
• Blepharospasm. In patients with blepharospasm, preliminary clinical research shows that taking zinc citrate 50 mg and phytase 3,000 units daily for four days prior to a botulinum toxin treatment increases the patient-reported duration of botulinum toxin effects by approximately 25%, compared with no improvement in patients taking zinc gluconate 10 mg or placebo. The efficacy of botulinum treatment was also improved (101913). Whether this reported benefit is due to the dose or form of zinc, citrate, phytase, the combination, or other factors, is unclear (101913,101914).
• Child growth. Clinical research in infants consuming a corn-based diet shows that taking a fat- and micronutrient-based food supplement containing phytase, docosahexaenoic acid (DHA), arachidonic acid, and lysine increases linear growth at age 8 and 10 months and improves locomotor development when compared with not taking this supplement. In contrast, a similar fat- and micronutrient-based supplement without phytase, DHA, arachidonic acid, and lysine does not improve these indices when compared with not taking a supplement. The phytase-containing supplement did not affect linear growth, weight for age, or hand-eye coordination at 12 months (101902). These reported benefits to child growth are likely to be due to the combination of provided essential and non-essential nutrients. Any role of phytase is expected to be minimal.
• Iron deficiency anemia. Taking phytase with a meal containing phytate and iron increases iron absorption (101903,101904,101906). However, the effect of phytase specifically for the treatment of iron deficiency anemia remains unclear (101902). Phytase is sometimes added to the diet to increase the absorption of iron from food. In a small study of women, some with iron deficiency anemia, incubating wheat as a source of phytase with a traditional grain high in phytate increased iron absorption from the meal to 8.3% from 2.6% (101904). Also, adding microbial phytase to whole wheat rolls containing phytate increases iron absorption from a meal by approximately 82% when compared with rolls without added phytase (101906). In another small study, the addition of a microbial phytase to a single corn meal with added micronutrients increases iron absorption and incorporation into red blood cells after 14 days by 1.85-fold when compared with the meal without added phytase (101903). However, consuming white wheat rolls with added wheat bran as a source of phytase does not increase iron absorption from the meal when compared to consuming rolls with added wheat bran with deactivated phytase (101906). The use of phytase as treatment for iron deficiency, with or without anemia, has rarely been investigated. However, clinical research in infants consuming a corn-based diet shows that taking a fat- and micronutrient-based food supplement containing phytase, docosahexaenoic acid (DHA), arachidonic acid, and lysine for 6 months does not seem to be more effective for reducing anemia than taking the food supplement without phytase (101902).
• Zinc deficiency. Preliminary clinical research shows that adding phytase 20.5 units to a millet-based porridge with added zinc immediately prior to consumption increases zinc absorption by approximately 68% in children aged 12-24 months (101911). Some of these children had low plasma levels of zinc at baseline. However, the use of phytase specifically for the treatment of zinc deficiency has not been investigated. More evidence is needed to rate phytase for these uses.

General ...No adverse effects have been reported in adults. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal adverse effects, such as necrotizing enterocolitis, when recombinant human bile salt-stimulated lipase is used in premature infants.

Gastrointestinal ...Orally, when added to the formula or pasteurized breast milk consumed by premature infants, recombinant human bile salt-stimulated lipase (rhBSSL) can cause gastrointestinal adverse effects, including abdominal distension, flatulence, constipation, colic, abdominal pain, gastroenteritis, vomiting, regurgitation, and rectal bleeding (101940). Premature infants receiving rhBSSL also had a slightly higher rate of necrotizing enterocolitis (NEC) when compared with those receiving placebo. After review by a panel of experts, it was determined that the rate of confirmed or suspected NEC in infants consuming rhBSSL was 3.3%, compared with 0.5% in those receiving placebo. Although this rate of NEC is lower than the historical rate of occurrence in premature infants (11%), a possible increased risk for NEC cannot be ruled out (101940).

General ...Panax notoginseng seems to be generally well tolerated when used orally or intravenously.
Most Common Adverse Effects:
Orally: Dry mouth, flushed skin, insomnia, nausea, nervousness, rash, vomiting.
Intravenously: Headache, itching, rash.
Serious Adverse Effects (Rare):
Intravenously: Fever, pustular drug eruption.

Dermatologic ...Orally, Panax notoginseng can cause flushed skin (5558). When given orally or intravenously, rash has been reported (94321,94324,94326,94378,98976). There is a case of interstitial granulomatous drug reaction in a 73-year-old male who had been using oral Panax notoginseng extract for 2 months. The condition repeated after 5 days of intravenous use at a later time. The skin condition gradually cleared after use of the product was discontinued (94316). In a retrospective review of hospital records of 30,884 patients, a specific Xueshuantong injection (XSTI) containing Panax notoginseng saponins was associated with a 4% incidence of skin reactions, including redness, itching, and maculopapules (98976).

Gastrointestinal ...Orally and intravenously, Panax notoginseng can cause dry mouth, nausea, and vomiting (5558,94321,98976). In one case report, a patient developed a large submucosal hematoma extending from the hypopharynx to lower esophagus after taking one oral dose of an unknown quantity of Panax notoginseng and hirudin (109671). It is unclear if this event was due to Panax notoginseng, hirudin, or other factors.

Immunologic ...Intravenously, Panax notoginseng saponins have been associated with five cases of pustular drug eruption due to acute generalized exanthematous pustulosis. The skin eruption was associated with fever and an increased neutrophil count in some cases. Symptoms were deemed to be probably or likely due to the Panax notoginseng product (94327). In a retrospective review of hospital records of 30,884 patients, a specific Xueshuantong injection (XSTI) containing Panax notoginseng saponins was associated with a fever frequency of 0.2%, edema frequency of 0.1%, and anaphylactic reactions in 0.03% (98976).

Neurologic/CNS ...Orally, Panax notoginseng can cause nervousness and insomnia (5558). Intravenously, Panax notoginseng has been reported to cause headache (94326,94378). In a retrospective review of hospital records of 30,884 patients, a specific Xueshuantong injection (XSTI) containing Panax notoginseng saponins was associated with a headache frequency of 0.3% and paresthesia frequency of 0.1% (98976).
