HelloPharmacist Scorecard of Schizandra Berry Extract by Herbadiet
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
This product contains a single active ingredient: schisandra berry extract powder. There are no other inactive ingredients listed.
Does it work?
Not established
The evidence we hold doesn't establish that schisandra is effective for any of the conditions listed—asthma, athletic performance, cough, diabetes, diarrhea, and hepatitis all rate as having insufficient reliable evidence. If you're considering this product for a specific health goal, your doctor or pharmacist can help you weigh what's known and what's not.
How safe is it?
Well-documented data
Schisandra is generally well tolerated over the short term in healthy adults, but high-quality safety data are limited. The most common side effects are decreased appetite, heartburn, stomach upset, and urticaria (a rash or hives).
The safety data advises against using schisandra during pregnancy because traditional sources suggest it may stimulate the uterus. There isn't enough reliable safety information to recommend it while breastfeeding—talk with your doctor or pharmacist for personalized guidance if you're nursing or planning to nurse.
Meds to double-check
Moderate interaction found
Before taking this product, check your medications against these types: tacrolimus and other CYP3A4 substrates (which schisandra can raise to unsafe levels), warfarin and blood thinners (which schisandra may weaken), CYP2C19 substrates like certain antifungals, CYP2C9 substrates, and P-glycoprotein substrates. All are Moderate severity concerns.
Use the medication search tool on this page to confirm your exact drugs.
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 berry extract is a single-ingredient supplement with documented interactions affecting hundreds of medications, most notably tacrolimus and drugs processed through major metabolic pathways. If you take any prescription medications—especially immunosuppressants, blood thinners, sedatives, antifungals, or anything metabolized by the liver—you need to check this product against your exact regimen before starting.
Talk with your doctor or pharmacist to see whether it's right for you.

HelloPharmacist Interaction Report
Schizandra Berry Extract by Herbadiet interacts with a substantial number of medications through its effects on how your body processes drugs.
The most serious concern involves tacrolimus (Prograf), an immunosuppressant: schisandra can raise tacrolimus levels by 183% to 268%, which risks toxicity and transplant rejection if not monitored closely.
Read the full breakdown — every affected drug type, severity by severity
Schisandra also affects several major drug-processing pathways. It inhibits CYP3A4 enzymes, potentially raising levels of many common medications including certain cancer drugs, sedatives, and immunosuppressants—a Moderate severity concern.
It may also increase levels of drugs that depend on P-glycoprotein transporters (Moderate), and inhibits CYP2C19, theoretically raising levels of some antifungals and other substrates (Moderate). On the flip side, it induces CYP2C9 and may reduce warfarin (Coumadin) effectiveness, potentially lowering your blood clotting protection (Moderate).
Schisandra can also increase midazolam (a sedative) levels and voriconazole (an antifungal) levels. Altogether, these interactions span 804 individual medications.
Because the list is extensive and overlaps many common prescriptions, use the medication checker on this page to search your exact drugs before starting this product, and talk it over with your doctor or pharmacist.

For each ingredient in Schizandra Berry Extract with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Schizandra berry extract 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.
