Schisandra chinensis is a woody vine berry from traditional Chinese medicine. The dried berries and extracts supply schisandrins and lignans that help the body handle stress.
Many take it to boost physical endurance, sharpen focus, and keep stress in balance. It also aids liver function and immunity. Powdered extract, tincture, and capsule forms are common.
Take it with food to prevent stomach upset. Begin with a low dose and increase slowly. Pregnant or nursing women should not use it. If you take prescription drugs, talk to your doctor before use.
