Schisandra
Uses
Parts Used & Where Grown
Schisandra is a woody vine with numerous clusters of tiny, bright red berries. It is distributed throughout northern and northeast China and the adjacent regions of Russia and Korea.1 The fully ripe, sun-dried fruit is used medicinally. It is purported to have sour, sweet, salty, hot, and bitter tastes. This unusual combination of flavors is reflected in schisandra’s Chinese name wu-wei-zi, meaning “five taste fruit.”
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 StarsReliable and relatively consistent scientific data showing a substantial health benefit.
2 StarsContradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 StarFor an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
| Used for | Why |
|---|---|
2 Stars Menopause Refer to label instructions | In a double-blind trial, supplementation with an extract of Schisandra chinensis improved symptoms related to menopause, compared with a placebo. In a double-blind trial, supplementation with an extract of Schisandra chinensis significantly improved symptoms related to menopause, compared with a placebo. The amount of Schisandra extract used was 196 mg twice a day for 6 weeks. |
1 Star Common Cold and Sore Throat Refer to label instructions | Adaptogens such as schisandra are thought to help keep various body systems—including the immune system—functioning optimally. Herbal supplements can help strengthen the immune system and fight infections. Adaptogens, which include eleuthero, Asian ginseng, astragalus, and , are thought to help keep various body systems—including the immune system—functioning optimally. They have not been systematically evaluated as cold remedies. However, one double-blind trial found that people who were given 100 mg of Asian ginseng extract in combination with a flu vaccine experienced a lower frequency of colds and flu compared with people who received only the flu vaccine. |
1 Star Fatigue Refer to label instructions | Schisandra fruit may have a weak adaptogenic action, and laboratory work suggests that it may improve work performance, build strength, and help to reduce fatigue. 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. |
1 Star Hay Fever (Asiasarum Root, Cassia Bark, Ginger, Licorice, Ma Huang, Peony, Pinellia) Refer to label instructions | The Japanese herbal formula known as sho-seiryu-to has been shown to reduce symptoms, such as sneezing, for people with hay fever. The Japanese herbal formula known as sho-seiryu-to has been shown to reduce symptom, such as sneezing, for people with hay fever. Sho-seiryu-to contains licorice, cassia bark, , ma huang, ginger, peony root, pinellia, and asiasarum root. |
1 Star Hepatitis 420 mg of silymarin per day | Compounds called lignans in schisandra appear to promote regeneration of liver tissue that has been damaged by harmful influences, such as hepatitis viruses or alcohol. Modern Chinese research suggests that compounds called lignans in promote regeneration of liver tissue that has been damaged by harmful influences, such as hepatitis viruses or alcohol. In a controlled trial, Chinese patients with chronic viral hepatitis were given 500 mg schisandra extract three times daily or liver extract and B vitamins. Among those given schisandra, serum glutamic pyruvic transaminase (SGPT) levels declined to normal levels in 68% compared to 44% of the control group. Lower SGPT levels suggest less liver inflammation. There was also a reduction in symptoms such as insomnia, fatigue, loose stools, and abdominal tension in the schisandra group. A preliminary trial in 5,000 people with various types of hepatitis found normalizations in SGPT or related liver enzymes in 75% of cases using an unspecified amount of schisandra. |
1 Star Infection Refer to label instructions | Schisandra supports the immune system and protects against microbes. Herbs that support a person’s immune system in the fight against microbes include the following: American ginseng, andrographis, Asian ginseng, astragalus, coriolus, eleuthero, ligustrum, maitake, picrorhiza, reishi, , and shiitake. |
1 Star Irritable Bowel Syndrome (Bupleurum, Dan Shen, Ginger, Wormwood) Take a Chinese herbal formula containing wormwood under the guidance of a qualified practitioner | A standardized Chinese herbal combination containing extracts from plants including wormwood, ginger, bupleurum, schisandra, and dan shen reduced IBS symptoms in one study. Whole peppermint leaf is often used either alone or in combination with other herbs to treat abdominal discomfort and mild cramping that accompany IBS. The combination of peppermint, caraway seeds, fennel seeds, and wormwood was reported to be an effective treatment for upper abdominal complaints in a double-blind trial. |
1 Star Liver Support Refer to label instructions | Schisandra lignans appear to protect the liver by activating the enzymes in liver cells that produce glutathione, an important antioxidant substance. 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. Schisandra lignans appear to protect the liver by activating the enzymes in liver cells that produce glutathione, an important antioxidant substance. |
Traditional Use (May Not Be Supported by Scientific Studies)
A classical treatise on Chinese herbal medicine, Shen Nung Pen Tsao Ching, describes schisandra as a high-grade herbal drug useful for a wide variety of medical conditions—especially as a kidney tonic and lung astringent. In addition, other textbooks on Traditional Chinese Medicine note that schisandra is useful for coughs, night sweats, insomnia, thirst, and physical exhaustion.2 Adaptogenic herbs, like schisandra, have been used in Traditional Chinese Medicine to improve the ability of the body to respond to stress.
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.3, 4 Schisandra lignans appear to protect the liver by activating the enzymes in liver cells that produce glutathione, an important antioxidant substance.5
How to Use It
Use of schisandra fruit ranges from 1.5–15 grams per day.6 The tincture, 2–4 ml three times per day, can also be used.

Explanation Required
- Acetaminophen
Gomisin A is a constituent found in the Chinese herb schisandra (Schisandra chinensis). In a study of rats given liver-damaging amounts of acetaminophen, gomisin A appeared to protect against some liver damage but did not prevent glutathione depletion (unlike milk thistle, as reported above). Studies have not yet confirmed this action in humans.
- Acetaminophen with Codeine
Gomisin A is a constituent found in the Chinese herb schisandra(Schisandra chinensis). In a study of rats given liver-damaging amounts of acetaminophen, gomisin A appeared to protect against some liver damage but did not prevent glutathione depletion (unlike milk thistle, as reported above). Studies have not yet confirmed this action in humans.
