How It Works
The major constituents in schisandra are lignans (schizandrin, deoxyschizandrin, gomisins, and pregomisin) found in the seeds of the fruit. Modern Chinese research suggests these lignans have a protective effect on the liver and an immunomodulating effect. Two human trials completed in China (one double-blind and the other preliminary) have shown that schisandra may help people with chronic viral hepatitis.11, 12 Schisandra lignans appear to protect the liver by activating the enzymes in liver cells that produce glutathione, an important antioxidant substance.13
Schisandra fruit may also have an adaptogenic action, much like the herb Asian ginseng, but with weaker effects. Laboratory work suggests that schisandra may improve work performance, build strength, and help to reduce fatigue.14
How to Use It
Use of schisandra fruit ranges from 1.5–15 grams per day.15 The tincture, 2–4 ml three times per day, can also be used.
