HelloPharmacist Scorecard of Schisandra by Moon Juice
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
Moon Juice Schisandra is a single-ingredient product: organic schisandra berry powder. Schisandra is a traditional berry used in herbal medicine, and this product contains just the powdered form with no added fillers or inactive ingredients listed.
Does it work?
Not established
The data we hold shows insufficient reliable evidence for schisandra in the uses listed—asthma, athletic performance, cough, diabetes, diarrhea, and hepatitis. That means the research so far isn't strong enough to call it effective for any of these.
If you're considering schisandra for a particular health concern, talk with your doctor or pharmacist about whether the evidence supports it for your situation.
How safe is it?
Well-documented data
Schisandra is generally well tolerated in short-term use by healthy adults, but high-quality safety studies are limited. The most common side effects are decreased appetite, heartburn, stomach upset, and urticaria (hives).
During pregnancy, schisandra is rated possibly unsafe because traditional sources suggest it may stimulate the uterus. While breastfeeding, there isn't enough reliable safety information, so it's best avoided.
If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking it.
Meds to double-check
Moderate interaction found
Before taking Moon Juice Schisandra, double-check with your pharmacist or doctor if you take tacrolimus (an immunosuppressant), any CYP3A4 substrate drugs, warfarin or other blood thinners, voriconazole or other antifungals, midazolam or other sedatives, or any P-glycoprotein substrate medications. Schisandra can change how these drugs work in your body, and the effect varies by drug—some may accumulate to unsafe levels, others may become less effective.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
Schisandra may appeal to people seeking a traditional herbal supplement, but the evidence for its effectiveness isn't established in the data we hold. The real caution here is interaction risk: if you take any prescription medications—especially blood thinners, immunosuppressants, sedatives, or antifungals—you need to check your specific drugs before starting.
Talk with your own doctor or pharmacist about whether it's right for you.

Organic Schisandra berry powder monograph & interactionsSchisandra by Moon Juice Drug Interactions
HelloPharmacist Interaction Report
Moon Juice Schisandra interacts with a substantial number of medications through its schisandra berry content.
The most serious concern is with tacrolimus (an immunosuppressant used after transplant), where schisandra can raise tacrolimus levels by 183% to 268%—a Moderate severity interaction that could cause toxicity. This is one of the few interactions confirmed in human studies.
Read the full breakdown — every affected drug type, severity by severity
Schisandra also affects how your body metabolizes drugs through several liver pathways. It can increase levels of medications processed by CYP3A4 (a major enzyme family) and may increase levels of P-glycoprotein substrate drugs.
Additionally, it theoretically may decrease the effectiveness of CYP2C9 substrates and could lower warfarin levels, potentially reducing blood-thinning protection. Voriconazole (an antifungal) and midazolam (a sedative) are also affected through CYP interactions.
Altogether, these interactions span 804 individual medications. Because many common drugs—blood thinners, immunosuppressants, sedatives, antifungals, and numerous others—depend on these liver enzymes, you should run your exact medications through the interaction checker on this page before starting schisandra.
If you take any prescription drug regularly, check with your own doctor or pharmacist first.

organic Schisandra berry powder
Cyclophosphamide
Theoretically, schisandra might increase the levels and clinical effects of cyclophosphamide.
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.
Cyclosporine (Neoral, Sandimmune)
Schisandra can increase the levels and clinical effects of cyclosporine.
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.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, schisandra might increase the levels and clinical effects of CYP2C19 substrates.
In vitro research shows that schisandra inhibits CYP2C19, and animal research shows that schisandra increases the concentration of voriconazole, a CYP2C19 substrate. Theoretically, schisandra may also inhibit the metabolism of other CYP2C19 substrates. This effect has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, schisandra might decrease the levels and clinical effects of CYP2C9 substrates.
In vitro and animal research suggests that schisandra induces CYP2C9 enzymes. This effect has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Schisandra can increase the levels and clinical effects of drugs metabolized by CYP3A4.
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. Although one in vitro and animal study shows that schisandra may induce CYP3A4 metabolism, this effect appears to be overpowered by schisandra's CYP3A4 inhibitory activity and has not been reported in humans.
Midazolam (Versed)
Schisandra can increase the levels and clinical effects of midazolam.
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.
P-Glycoprotein Substrates
Schisandra might increase the levels and clinical effects of P-glycoprotein substrates.
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. Additionally, a small clinical study shows that schisandra increases the peak concentration and overall exposure to talinolol, a P-glycoprotein probe substrate. Theoretically, schisandra might inhibit the efflux of other P-glycoprotein substrates.
Sirolimus (Rapamune)
Schisandra can increase the levels and clinical effects of sirolimus.
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.
Tacrolimus (Prograf)
Schisandra can increase the levels and clinical effects of tacrolimus.
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%. This effect is thought to be due to inhibition of P-glycoprotein drug transporter and CYP3A4 and CYP3A5 by schisandra. 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. Animal research suggests that the greatest increase in tacrolimus levels occurs when schisandra is taken either concomitantly or up to 2 hours before tacrolimus, 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.
Talinolol
Schisandra can increase the levels and clinical effects of talinolol.
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.
tly.
Voriconazole (Vfend)
Theoretically, schisandra might increase the levels and clinical effects of voriconazole.
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. However, this interaction has not been reported in humans.
Warfarin (Coumadin)
Theoretically, schisandra might decrease the levels and clinical effects of warfarin.
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. However, this interaction has not been reported in humans.
