• Age-related macular degeneration (AMD). It is unclear if oral goji berry reduces the risk of developing AMD. Details: A small, unblinded clinical study in healthy adults aged 45 to 65 years shows that consuming goji berries 28 grams five times a week for 90 days improves macular pigment optical density, which is a marker for AMD, when compared to baseline (110767). The validity of this finding is limited by the lack of statistical comparison to the other study group that received a supplement containing lutein and zeaxanthin.
• Cancer. Although there is interest in using oral goji for cancer, there is insufficient reliable information about the clinical effects of goji for this condition.
• Cardiovascular disease (CVD). It is unclear if oral goji improves risk factors for CVD. Details: A meta-analysis of 6 mostly small clinical studies of adults in China shows that consuming goji as polysaccharide extract or juice for 1-3 months modestly improves triglycerides, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and fasting blood glucose but does not impact total cholesterol when compared with no treatment or placebo (110765). Another meta-analysis of 4 small clinical studies in adults also shows that consuming goji polysaccharide extract or goji berries for 1-4 months modestly improves triglycerides and HDL but does not impact total or LDL cholesterol when compared with placebo or healthy eating. Goji also had no impact on systolic or diastolic blood pressure, or markers of oxidative stress (110768). However, the interpretation of the findings from these meta-analyses is limited by the use of variable goji forms and doses, as well as inclusion of studies in heterogeneous patients, including healthy people, patients with diabetes, and patients with metabolic syndrome. Furthermore, most studies were conducted in China; it is unclear if these benefits can be extrapolated to other geographic locations.
• Cognitive function. It is unclear if oral goji berry improves cognition in healthy young individuals. Details: A small clinical crossover study in healthy participants 14-24 years of age shows that taking goji berry fruit water extract (BIOMIX Company) 3600 mg in 3 divided doses daily for 4 weeks might improve certain cognitive measures such as verbal learning, short-term memory, and attention when compared with baseline (105488). The validity of these findings are limited due to incomplete outcome reporting and a lack of statistical comparisons between the treatment and placebo groups.
• Cough. Although there is interest in using oral goji for cough, there is insufficient reliable information about the clinical effects of goji for this purpose.
• Depression. It is unclear if oral goji berry polysaccharide is beneficial for adolescents with subthreshold depression. Details: A small clinical study in adolescents aged approximately 15 years with subthreshold depression in China shows that taking goji berry polysaccharide extract 300 mg daily for 6 weeks modestly improves clinician-assessed depression scores (i.e. Hamilton Depression Scale, HAMD-24) but does not improve self-reported depression scores (i.e. Beck Depression Inventory) or scores assessing sleep quality, psychological distress, or anxiety when compared with placebo (110769). However, these results are from an interim analysis, which limits the interpretation of these findings. Furthermore, it is unclear if results can be extrapolated to patients in other geographic locations.
• Diabetes. It is unclear if oral goji berry polysaccharides improve glycemic control in patients with diabetes. Details: One small clinical study in patients with type 2 diabetes shows that taking goji fruit polysaccharide powder 150 mg twice daily for 3 months results in a slightly lower postprandial glucose area under the curve (AUC), but does not seem to affect insulin levels or insulin resistance, when compared with placebo. A subgroup of patients who were not taking antidiabetes medications had a greater reduction in postprandial blood glucose (92117).
• Dry eye. Although there is interest in using oral goji for dry eye, there is insufficient reliable information about the clinical effects of goji for this purpose.
• Erectile dysfunction (ED). Although there is interest in using oral goji for ED, there is insufficient reliable information about the clinical effects of goji for this condition.
• Hypertension. Although there is interest in using oral goji root bark for hypertension, there is insufficient reliable information about the clinical effects of goji for this condition.
• Obesity. It is unclear if oral goji berry juice improves weight loss. Details: Preliminary clinical research in healthy, overweight adults shows that drinking a specific goji fruit juice (GoChi, FreeLife International LLC) 120 mL daily for 14 days while following a weight loss diet and participating in an exercise program decreases waist circumference by about 4.7 cm more than exercise and diet alone. However, drinking goji berry juice along with diet and exercise does not improve body weight, body mass index, or body fat when compared with diet and exercise alone (52536).
• Quality of life. Small clinical studies suggest that oral goji berry juice may modestly improve quality of life in healthy adults. Details: Small clinical studies in healthy adults suggest that taking a specific standardized goji fruit juice (GoChi, FreeLife International LLC) 120 mL daily for 14-30 days improves subjective measures of energy levels, athletic performance, sleep quality, mental acuity, calmness, feelings of well-being, and gastrointestinal regularity when compared with placebo (17082,52532,52542). These studies were funded by the juice manufacturer.
• Sunburn. It is unclear if oral goji extract can prevent sunburn. Details: A small clinical study in healthy Japanese adults shows that taking goji extract 900 mg daily for 8 weeks reduces and accelerates resolution of erythema after exposure to a standard dose of UVB irradiation when compared with placebo (110770). All study participants were highly UV-sensitive; it is unclear whether these results can be extrapolated to individuals less sensitive to UV irradiation.
• Tinnitus. Although there is interest in using oral goji for tinnitus, there is insufficient reliable information about the clinical effects of goji for this purpose. More evidence is needed to rate goji for these uses.

POSSIBLY EFFECTIVE

• Menopausal symptoms. Several clinical studies suggest that oral royal jelly, taken alone or in combination with other ingredients, modestly improves menopausal symptoms. It is unclear if topical royal jelly is beneficial for this use. Details: One clinical study in postmenopausal patients shows that taking royal jelly 1000 mg daily for 8 weeks reduces menopausal symptom scores by around 30% when compared with placebo (102527). Other small clinical studies show that taking one to two capsules of a specific combination product containing royal jelly and flower pollen (Melbrosia) daily for 12 weeks reduces menopausal symptoms and improves feelings of well-being when compared with baseline or placebo (18064,71956,72005). Another clinical trial in postmenopausal patients shows that taking two capsules of a specific combination product containing royal jelly, evening primrose oil, damiana, and ginseng (Lady 4) daily for 4 weeks decreases self-rated menopausal symptoms when compared with placebo (21003). Topical royal jelly has also been evaluated. A small clinical study in postmenopausal adults shows that applying vaginal cream containing royal jelly 15% daily for 12 weeks improves quality of life, sexual problems, and urinary problems similarly to vaginal estrogen cream 0.625 mg. However, estrogen cream improves vaginal atrophy better than royal jelly (92884).

POSSIBLY INEFFECTIVE

• Allergic rhinitis (hay fever). Oral royal jelly does not appear to prevent or treat symptoms of allergic rhinitis in children. Details: A clinical trial in children 5-16 years of age with allergic rhinitis shows that taking a specific royal jelly product (Bidro) 150 mg twice daily for 3-6 months before and during pollen season does not prevent or treat nasal congestion, sneezing, or eye discomfort when compared with placebo (71968).
• Diabetes. Oral royal jelly does not appear to improve glycemic control in patients with type 2 diabetes. Details: Most clinical research in patients with type 2 diabetes, along with a meta-analysis of five small clinical trials including patients with or without type 2 diabetes, shows that taking royal jelly 0.5-6 grams daily for 4-8 weeks does not improve markers of glycemic control such as fasting plasma glucose and glycated hemoglobin (HbA1c) (92879,92880,92881,102529).
• Physical performance. Oral royal jelly does not appear to improve physical performance in elderly nursing home residents. Details: A clinical trial in elderly nursing home residents shows that taking royal jelly 1.2 grams or 4.8 grams daily for one year does not improve hand grip strength, walking, or ability to stand on one leg when compared with placebo (95870).

• Androgenic alopecia. Although there has been interest in using topical royal jelly for androgenic alopecia, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Atherosclerosis. Although there has been interest in using oral royal jelly for atherosclerosis, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Athletic performance. Oral royal jelly has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Two small clinical trials in elite male swimmers and runners show that taking royal jelly 400 mg and coenzyme Q10 60 mg daily for 10 days does not improve high-intensity interval training performance when compared with placebo (109992,109993). These studies were small and may not have been adequately powered to detect a difference between groups.
• Cancer-related fatigue. It is unclear if oral royal jelly is beneficial for improving cancer-related fatigue. Details: A small clinical study in patients with solid (nonhematologic) malignancies shows that taking 5 mL of processed honey and royal jelly twice daily for 4 weeks reduces fatigue when compared with 5 mL of honey alone (92877).
• Chemotherapy-induced acral erythema. It is unclear if oral royal jelly is beneficial for preventing acral erythema from tyrosine kinase inhibitors (TKIs). Details: One small clinical trial in patients receiving TKI therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months does not reduce the risk of acral erythema when compared with placebo (105773). However, this study may have been inadequately powered to detect a difference between groups.
• Chemotherapy-induced hepatotoxicity. It is unclear if oral royal jelly is beneficial for preventing hepatotoxicity from tyrosine kinase inhibitors (TKIs). Details: One small clinical trial in patients receiving TKI therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months does not reduce the risk of hepatotoxicity when compared with placebo (105773). However, this study may have been inadequately powered to detect a difference between groups.
• Chemotherapy-induced nephrotoxicity. It is unclear if oral royal jelly is beneficial for preventing chemotherapy-induced nephrotoxicity. Details: A small clinical study in patients receiving two cycles of cisplatin therapy shows that taking royal jelly capsules daily may attenuate increases in serum creatinine and urea levels when compared with placebo. However, it is unclear if this effect is clinically significant; the increased levels that occurred in the placebo group were still within normal limits (95871). The validity of these results is also limited by the short study duration and lack of statistical comparison between groups. Another small clinical trial in patients receiving tyrosine kinase inhibitor therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months does not reduce the risk of kidney dysfunction when compared with placebo (105773). However, this study may have been inadequately powered to detect a difference between groups.
• Chemotherapy-related fatigue. It is unclear if oral royal jelly is beneficial for preventing fatigue from tyrosine kinase inhibitors (TKIs). Details: One small clinical trial in patients receiving TKI therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months reduces the frequency of chemotherapy-related fatigue when compared with placebo (105773,105774).
• Cognitive impairment. Oral royal jelly has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial 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, ginkgo leaf extract 120 mg, and Panax ginseng root extract 150 mg, daily for 4 weeks improves cognitive ability when compared with placebo (89712).
• Coronavirus disease 2019 (COVID-19). Oral royal jelly has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-sized clinical study in adults without diabetes in Iran hospitalized with moderately severe COVID-19 receiving corticosteroids shows that taking a specific combination supplement (Tang Forte, HealthAid) containing royal jelly extract 350 mg and vitamin E 2 mg daily for 7 days does not improve markers of the clinical course of COVID-19, such as oxygen saturation or length of hospital stay, when compared with placebo (114535). However, this study may not have been adequately powered to detect a difference between groups. It is unclear if this effect is due to royal jelly, other ingredients, or the combination.
• Diabetic foot ulcers. Small clinical studies suggest that topical application of royal jelly plus panthenol may improve healing of diabetic foot ulcers. It is unclear if topical royal jelly alone is beneficial for this use. Details: One small clinical study shows that applying royal jelly 5% to a wound after conventional cleansing and debriding three times weekly for 3 months does not improve the healing of diabetic foot ulcers when compared with placebo (92882). However, other small clinical studies show that applying 1-3 grams of a specific combination ointment (Pedyphar) containing royal jelly and panthenol after conventional cleansing and debriding procedures twice weekly for up to 6 months may improve the healing of diabetic foot ulcers (71980,102526). In one of these studies, the rate of complete healing of life-threatening ulcers was 2.7-fold greater with this combination ointment when compared with panthenol alone (102526). Possible reasons for these discrepancies include the use of combination versus single ingredient ointments and the duration of treatment.
• Dry eye. It is unclear if oral royal jelly is beneficial in patients with dry eye. Details: A small clinical trial in Japanese patients with dry eye shows that taking enzyme-treated royal jelly 2.4 grams daily for 8 weeks does not improve tear stability or dry eye symptoms when compared with placebo (95869).
• Fractures. Although there has been interest in using oral royal jelly for healing of fractures, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Hepatitis. Although there has been interest in using oral royal jelly for hepatitis, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Male infertility. Intravaginal application of royal jelly has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in couples experiencing infertility due to asthenozoospermia shows that applying a saline solution containing royal jelly 3 grams, Egyptian bee honey 100 grams, and bee bread 1 teaspoon intravaginally before or after intercourse, starting one day after menstruation and continuing for 2 weeks, can increase the rate of pregnancy when compared with intrauterine insemination (55131). It is unclear if this effect is due to royal jelly, other ingredients, or the combination.
• Obesity. It is unclear if oral royal jelly is beneficial for reducing body weight in patients who are overweight or obese. Details: One small clinical study in overweight patients with type 2 diabetes shows that taking fresh royal jelly 1 gram daily for 8 weeks reduces body weight by around 2 kg and body mass index (BMI) by around 0.7 kg/m², as well as carbohydrate and total energy intake, when compared with placebo. However, the improvement is modest and may not be clinically significant (92878). Another small clinical study in overweight adults shows that taking royal jelly 1000 mg daily for 8 weeks does not reduce body weight, BMI, or appetite when compared with placebo (102528). However, this study may have been inadequately powered to detect a difference in these outcomes.
• Oral mucositis. It is unclear if oral royal jelly is beneficial for preventing or treating oral mucositis in patients receiving radiotherapy and/or chemotherapy. Details: One small clinical trial in patients receiving chemotherapy and radiotherapy shows that swishing and swallowing royal jelly 1 gram in two divided doses daily, in addition to standard rinses with benzydamine and nystatin, improves healing time of mild or moderate oral mucositis when compared with standard rinses alone (95867).
• Osteoporosis. It is unclear if oral royal jelly is beneficial in patients with osteoporosis. Details: A small clinical trial in postmenopausal adults shows that taking royal jelly powder 1000 mg, equivalent to 3000 mg of fresh royal jelly, daily for 6 months maintains bone mineral density (BMD) in the proximal femur and lumbar spine, while patients taking placebo saw significant reductions in lumbar spine BMD. Also, markers of bone turnover were significantly reduced with placebo, while significant changes in these markers were lacking in patients taking royal jelly (105775). It is unclear whether these findings can be generalized to patients with documented osteoporosis.
• Peptic ulcers. Although there has been interest in using oral royal jelly for peptic ulcers, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Premenstrual syndrome (PMS). It is unclear if oral royal jelly, taken alone or in combination with other ingredients, is beneficial in patients with PMS. Details: A small clinical study in healthy college students shows that taking royal jelly 1 gram daily starting on the first day of menstruation and continuing for two consecutive menstrual cycles improves PMS symptoms when compared with placebo (95873). However, methodological flaws associated with the study limit the validity of these results. A small clinical study shows that taking a specific combination product (Femal, Natumin Pharma), providing royal jelly 12 mg, bee pollen extract 72 mg, and bee pollen plus pistil extract 240 mg, twice daily over 2 menstrual cycles seems to decrease some symptoms of PMS including irritability, weight increases, and edema (12008). It is unclear if these effects are due to royal jelly, other ingredients, or the combination.
• Renal cell carcinoma. It is unclear if oral royal jelly is beneficial in patients with renal cell carcinoma. Details: One small clinical trial in patients receiving tyrosine kinase inhibitor (TKI) therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months reduces tumor size, improves chemotherapy-related fatigue and anorexia, and reduces the need for dose reduction or the discontinuation of therapy when compared with placebo (105773,105774). Royal jelly does not seem to reduce other TKI-related adverse effects, including gastrointestinal symptoms, oral mucositis, acral erythema, anemia, hepatotoxicity, or nephrotoxicity, when compared with placebo (105773). However, this study may have been inadequately powered to detect a difference in these outcomes. More evidence is needed to rate royal jelly for these uses.

• Impaired glucose tolerance (prediabetes). Oral schisandra has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate sized clinical trial in adults with prediabetes shows that taking schisandra fruit extract with a soybean mixture 250 mg twice daily for 12 weeks decreases fasting plasma glucose by around 6 mg/dL and improves 30- and 60-minute post-prandial glucose levels but does not reduce glycated hemoglobin when compared with placebo (112887). The ratio of the schisandra extract to soybean mixture in the product was 5:1. It is unclear if these effects are due to schisandra, soybean, or the combination.
• Menopausal symptoms. It is unclear if oral schisandra is beneficial for improving menopausal symptoms. Details: A small clinical trial in healthy patients with moderate or severe menopausal symptoms shows that taking schisandra extract (BMO-30, Biomix Inc) 784 mg in two divided doses daily for 6 weeks improves hot flushes and other menopausal symptoms when compared with placebo (96632).
• Muscle strength. It is unclear if oral schisandra is beneficial for improving muscle strength. Details: A small clinical study in healthy middle-aged females shows that taking schisandra powdered extract (Bioport Korea Inc.) 500 mg twice daily for 12 weeks seems to modestly increase quadriceps muscle strength and grip strength, but does not affect overall muscle mass, when compared with placebo (105563).
• Myopia. Although there is interest in using topical schisandra for myopia in children, there is insufficient reliable information about the clinical effects of schisandra for this condition.
• Physical performance. It is unclear if oral schisandra is beneficial for improving physical function in older adults. Details: A small clinical study in healthy adults over 50 years of age shows that taking schisandra 500 mg twice daily, 30 minutes after breakfast and dinner, for 12 months improves knee extension peak torque, but does not improve hand grip strength or body composition, when compared with placebo (105562).
• Pneumonia. Oral schisandra has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with acute, nonspecific pneumonia shows that taking 20 mL of a specific combination product (ADAPT-232 CHI San, Swedish Herbal Institute) containing schisandra berry extract 51%, rhodiola root extract 27.6%, and eleuthero root extract 24.4% twice daily for 10-15 days reduces the duration of antibiotic treatment and may improve quality of life when compared with standard treatment alone (71152). It is unclear if these effects are due to schisandra, other ingredients, or the combination.
• Stress. Oral schisandra has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy, fatigued females under experimental stress suggests that taking a single, 270 mg dose of a combination product (ADAPT-232, Swedish Herbal Institute) containing schisandra, rhodiola, and Siberian ginseng improves attention, as well as cognitive task speed and accuracy, when compared with placebo (19289). It is unclear if these effects are due to schisandra, other ingredients, or the combination. More evidence is needed to rate schisandra for these uses.

POSSIBLY SAFE ...when goji fruit preparations are used orally and appropriately, short-term. Goji berry whole fruit, boiled or steamed, has been used with apparent safety at a dose of 15 grams daily for 16 weeks (105489). Other goji berry products have also been used with apparent safety in clinical research, including a specific goji fruit juice (GoChi, FreeLife International) 120 mL daily for 30 days (52532), a goji fruit polysaccharide 300 mg daily for 3 months (92117), and a specific milk-based formulation of goji berry (Lacto-Wolfberry, Nestlé Research Center) for 3 months (52539). There has been some concern about the atropine content of goji; however, most analyses show that levels of atropine in goji berries from China and Thailand are far below potentially toxic levels (52524,94667). There is insufficient reliable information available about the safety of oral use of other parts of the goji plant.

FLECAINIDE (Tambocor) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might increase the levels and clinical effects of flecainide.  Details In one case report, a 75-year-old patient stable on flecainide and warfarin presented to the emergency room with fainting and pleomorphic arrhythmia caused by flecainide toxicity. Flecainide toxicity was attributed to drinking 1-2 glasses of concentrated goji tea daily for 2 weeks. Theoretically, goji may have inhibited the cytochrome P450 2D6 (CYP2D6) metabolism of flecainide (105462).

WARFARIN (Coumadin) Interaction Rating = Major Do not take this combination. Severity = High •  Occurrence = Probable •  Level of Evidence = D Goji can increase the effects of warfarin and possibly increase the risk of bleeding.  Details There are at least 5 case reports of increased international normalized ratio (INR) in patients stabilized on warfarin who began drinking goji juice, concentrated goji tea, or goji wine (7158,16529,23896,105462,105487). Goji may inhibit the metabolism of warfarin by cytochrome P450 2C9 (CYP2C9) (7158).

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

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

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

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

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

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

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

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

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

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

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

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