Also known as: Schisandra chinensis, Five-Flavor Berry, Wu Wei Zi
Schisandra chinensis is a traditional adaptogenic berry used in Chinese and Russian medicine. Its lignans, particularly schisandrin B, support liver function, enhance stress resilience, and improve mental performance under fatigue.
Schisandra chinensis, known as the five-flavor berry (wu wei zi) in traditional Chinese medicine, is a woody vine native to northeastern China, Korea, and Russia. Its berries uniquely express all five fundamental tastes—sweet, sour, salty, bitter, and pungent—reflecting a complex phytochemical profile. The primary bioactive compounds are dibenzocyclooctadiene lignans, including schisandrin A, B, and C, schisandrol A and B, and gomisins. These lignans are classified as adaptogens, compounds that enhance the body's non-specific resistance to physical, chemical, and biological stressors. Schisandra lignans activate the Nrf2 antioxidant response element, upregulating endogenous antioxidant enzymes and providing hepatoprotective effects. In Soviet-era research, schisandra was extensively studied for improving work capacity, reducing fatigue, and enhancing accuracy under stress in military and athletic contexts. Modern clinical trials confirm improvements in cognitive function under fatigue, stress hormone regulation, and liver enzyme normalization in patients with hepatitis.
Controlled human trials show schisandra extract improves attention, speed, and accuracy in cognitive tasks performed under fatigue and stress conditions, consistent with adaptogenic mechanisms.
Schisandrin B activates the Nrf2 pathway, upregulating phase II detoxification enzymes and glutathione synthesis. Clinical studies show normalization of elevated liver enzymes in chronic hepatitis patients.
As a pharmacologically validated adaptogen, schisandra regulates cortisol levels and HPA axis activity, helping the body adapt to physical and psychological stressors.
Once or twice daily, preferably in the morning and early afternoon
Look for extracts standardized to ≥3% schisandrins. Traditional use involves 1.5–6 g dried berries daily.
Divided into 2 doses with meals
Higher doses have been used in hepatitis studies under medical supervision.
Consistent lignan content for adaptogenic support
Traditional use as tea or culinary ingredient
