• 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.

• Constipation. It is unclear if oral zizyphus fruit extract is beneficial in patients with constipation. Details: A small clinical study in patients with idiopathic constipation shows that taking zizyphus fruit extract 20-40 drops daily for 12 weeks improves bloating, abdominal pain, difficult evacuation, and quality of life when compared to baseline. Significant improvements in constipation-related symptoms were lacking in patient taking placebo drops (93316). The validity of these findings is limited by the lack of statistical comparison between groups.
• Diabetes. It is unclear if oral zizyphus fruit powder is beneficial in patients with type 2 diabetes. Details: A small clinical study in patients with type 2 diabetes shows that taking zizyphus fruit powder 30 grams daily for 12 weeks reduces measures of insulin resistance and improves measures of insulin sensitivity, but does not affect fasting blood glucose levels or glycated hemoglobin, when compared with placebo (104507).
• Diarrhea. Although there has been interest in using oral zizyphus for diarrhea, there is insufficient reliable information about the clinical effects of zizyphus for this purpose.
• Epilepsy. Although there has been interest in using oral zizyphus for epilepsy, there is insufficient reliable information about the clinical effects of zizyphus for this purpose.

CYCLOPHOSPHAMIDE Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Theoretically, schisandra might increase the levels and clinical effects of cyclophosphamide.  Details In vitro research shows that schisandra increases the concentration of cyclophosphamide, likely through inhibition of cytochrome P450 3A4. After multiple doses of the schisandra constituents schisandrin A and schisantherin A, the maximum concentration of cyclophosphamide was increased by 7% and 75%, respectively, while the overall exposure to cyclophosphamide was increased by 29% and 301%, respectively (109636).

CYCLOSPORINE (Neoral, Sandimmune) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of cyclosporine.  Details A small observational study in children with aplastic anemia found that taking schisandra with cyclosporine increased cyclosporine trough levels by 93% without increasing the risk of adverse events. However, the dose of cyclosporine was reduced in 9% of children to maintain appropriate cyclosporine blood concentrations (109637).

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Theoretically, schisandra might increase the levels and clinical effects of CYP2C19 substrates.  Details In vitro research shows that schisandra inhibits CYP2C19, and animal research shows that schisandra increases the concentration of voriconazole, a CYP2C19 substrate (105566). Theoretically, schisandra may also inhibit the metabolism of other CYP2C19 substrates. This effect has not been reported in humans.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, schisandra might decrease the levels and clinical effects of CYP2C9 substrates.  Details In vitro and animal research suggests that schisandra induces CYP2C9 enzymes (14441). This effect has not been reported in humans.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Schisandra can increase the levels and clinical effects of drugs metabolized by CYP3A4.  Details Most clinical and laboratory research shows that schisandra, administered either as a single dose or up to twice daily for 14 days, inhibits CYP3A4 and increases the concentration of CYP3A4 substrates such as cyclophosphamide, midazolam, tacrolimus, and talinolol (13220,17414,23717,91386,91388,91387,96631,105564,109636,109638,109639,109640,109641). Although one in vitro and animal study shows that schisandra may induce CYP3A4 metabolism (14441), this effect appears to be overpowered by schisandra's CYP3A4 inhibitory activity and has not been reported in humans.

MIDAZOLAM (Versed) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of midazolam.  Details A small pharmacokinetic study in healthy adults shows that taking schisandra extract (Hezheng Pharmaceutical Co.) containing deoxyschizandrin 33.75 mg twice daily for 8 days and a single dose of midazolam 15 mg on day 8 increases the overall exposure to midazolam by about 119%, increases the peak plasma level of midazolam by 86%, and decreases midazolam clearance by about 52%. This effect has been attributed to inhibition of CYP3A4 by schisandra (91388).

P-GLYCOPROTEIN SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Schisandra might increase the levels and clinical effects of P-glycoprotein substrates.  Details In vitro research shows that schisandra extracts and constituents such as schisandrin B inhibit P-glycoprotein mediated efflux in intestinal cells and in P-glycoprotein over-expressing cell lines (17414,105643,105644). Additionally, a small clinical study shows that schisandra increases the peak concentration and overall exposure to talinolol, a P-glycoprotein probe substrate (91386). Theoretically, schisandra might inhibit the efflux of other P-glycoprotein substrates.

SIROLIMUS (Rapamune) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of sirolimus.  Details A small pharmacokinetic study in healthy volunteers shows that taking 3 capsules of schisandra (Hezheng Pharmaceutical Company) containing a total of 33.75 mg deoxyschizandrin twice daily for 13 days and then taking a single dose of sirolimus 2 mg increases the overall exposure and peak level of sirolimus by two-fold. This effect is thought to be due to inhibition of cytochrome P450 3A4 by schisandra, as well as possible inhibition of the P-glycoprotein drug transporter (105643).

TACROLIMUS (Prograf) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of tacrolimus.  Details Clinical research in healthy volunteers and transplant patients shows that taking schisandra with tacrolimus increases tacrolimus peak levels by 183% to 268%, increases overall exposure to tacrolimus by 126% to 343%, and decreases tacrolimus clearance by 48% to 73%. This effect is thought to be due to inhibition of CYP3A4 by schisandra, and possibly also inhibition of the P-glycoprotein drug transporter. It may also be related to the inhibition of CYP3A5 in people who are CYP3A5 expressors. Small clinical studies show that schisandra increases tacrolimus levels in both expressors and non-expressors of CYP3A5 (15570,17414,91387,96631,105623,109639,109641). However, some clinical and observational research shows that schisandra increases tacrolimus levels to a greater degree in CYP3A5 expressors when compared with CYP3A5 non-expressors (109638,109640). Animal research suggests that the greatest increase in tacrolimus levels occurs when schisandra is taken either concomitantly or up to 2 hours before tacrolimus (105564).

TALINOLOL Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of talinolol.  Details A small pharmacokinetic study in healthy volunteers shows that taking schisandra extract 300 mg twice daily for 14 days with a single dose of talinolol 100 mg on day 14 increases the peak talinolol level by 51% and the overall exposure to talinolol by 47%. This effect is thought to be due to the possible inhibition of cytochrome P450 3A4 and P-glycoprotein by schisandra (91386). tly.

VORICONAZOLE (Vfend) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, schisandra might increase the levels and clinical effects of voriconazole.  Details Animal research shows that oral schisandra given daily for 1 or 14 days increases levels of intravenously administered voriconazole, a cytochrome P450 (CYP) 2C19 substrate. This effect is thought to be due to inhibition of CYP2C19 by schisandra (105566). However, this interaction has not been reported in humans.

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, schisandra might decrease the levels and clinical effects of warfarin.  Details Animal research suggests that oral schisandra extract, given daily for 6 days, reduces levels of intravenously administered warfarin. This effect might be due to the induction of cytochrome P450 (CYP) 2C9 metabolism by schisandra (14441). However, this interaction has not been reported in humans.
