What is it
Schisandra (Schisandra chinensis) is a woody vine native to East Asia that produces small red berries. The dried berries have been used in traditional Chinese medicine for over 2,000 years as an adaptogen, hepatoprotective herb, and tonic for fatigue and respiratory conditions. The Chinese name 'wu wei zi' means 'five-flavor berry' because the fruit contains all five traditional taste qualities.

fatigue and stress tolerance
Supplement benefitClassified as an adaptogen, schisandra is theorized to modulate the HPA stress axis, and some preliminary studies suggest benefits for fatigue and stress tolerance. Clinical evidence is limited and results for stress and performance have been mixed.
Bottom line: Traditional adaptogen with preliminary, mixed evidence for fatigue and stress.

Frequently asked questions
Why is schisandra called the 'five-flavor berry'?⌄
The Chinese name 'wu wei zi' refers to traditional Chinese medicine's concept that schisandra berries express all five primary tastes: sweet, sour, bitter, salty, and pungent. This unusual flavor complexity is part of its traditional significance.
Can schisandra help my liver?⌄
Some trials in chronic hepatitis suggest modest improvements in liver enzyme markers. Schisandra is not a substitute for evaluated liver disease treatment, and people with liver disease should use it only under medical supervision.
Is schisandra a stimulant?⌄
Schisandra is not a strong stimulant in the way caffeine is. It is classified as an adaptogen and may modestly affect energy and stress tolerance over weeks of use rather than producing acute stimulation.
How long until I notice effects?⌄
For adaptogen or liver effects, daily use over 4 to 12 weeks is typical before judging effects.
Is schisandra safe in pregnancy?⌄
No. Avoid schisandra in pregnancy due to potential uterine-stimulating effects and traditional cautions.
