Overview

Schisandra (Schisandra chinensis), also known as wu wei zi (“5-flavored herb”), is a woody vine that can grow up to 26 ft (8 m). It has pink blossoms and clusters of bright red berries containing powerful adaptogenic, antioxidant, and liver-protective constituents.

Traditional uses & properties

Adaptogen & Restorative: Boosts energy, helps coping with stress, and may aid sexual vitality. Hepatoprotective: Lignans support and protect liver function, beneficial for hepatitis and toxin-related liver damage. Nervous System Regulator: Can simultaneously stimulate and calm, reducing mild anxiety or irritability while improving mental clarity. Moistening: Lubricates dry tissues, traditionally helping coughs, night sweats, and thirst.

500–1,500 mg, 1–2 times daily

Drug & food interactions

Schisandra may modestly induce the metabolism of warfarin and greatly increase the absorption of tacrolimus, but it appears to have little effect on the metabolism of nifedipine.

Warfarin and related drugs

The interaction between schisandra and warfarin is based on experimental evidence only. No interactions found.

Tacrolimus

Schisandra greatly increases tacrolimus levels and its adverse effects. In a pharmacokinetic study, 12 healthy subjects were given an extract of Schisandra sphenanthera (containing 33.75 mg schizandrin) twice daily for 14 days, with a single 2-mg oral dose of tacrolimus on day 14. The extract of Schisandra sphenanthera increased the AUC and maximum plasma concentrations of tacrolimus by 164% and 227%, but did not alter its half-life. Six of the 12 subjects experienced indigestion, and burning hands and feet, one hour after both medicines were given. These symptoms resolved over 10 hours.

Nifedipine

The interaction between schisandra and nifedipine is based on experimental evidence only. No interactions found.

Food

No interactions found.

Habitat

Cultivated primarily in northeastern China, schisandra prefers sunny conditions. The berries are collected fully ripe in autumn. Related species are similarly used in traditional East Asian medicine.
