Schisandra is a plant. The fruit is used as food and also to make medicine.
Schisandra is used as an "adaptogen" for increasing resistance to disease and stress, increasing energy, and increasing physical performance and endurance.
Schisandra is also used for preventing early aging and increasing lifespan, normalizing blood sugar and blood pressure, stimulating the immune system, and speeding recovery after surgery.
It is also used for treating liver disease (hepatitis) and protecting the liver from poisons. The Chinese have developed a liver-protecting drug called DBD that is made from schizandrin, one of the chemicals in schisandra.
Other uses for schisandra include treatment of high cholesterol, pneumonia, coughs, asthma, sleep problems (insomnia), tiredness and irritability associated with emotional disturbance (neurasthenia), premenstrual syndrome (PMS), chronic diarrhea, dysentery, night sweats, spontaneous sweating, involuntary discharge of semen, thirst, erectile dysfunction (ED), physical exhaustion, excessive urination, depression, irritability, and memory loss. It is also used in children to reduce the frequency and severity of attacks of fever associated with an inherited disease called familial Mediterranean fever.
Some people use schisandra for improving vision ad muscular activity, protecting against radiation, preventing motion sickness, preventing infection, boosting energy at the cellular level, and improving the health of the adrenal glands.
Schisandra fruit is eaten as a food.
The chemicals in schisandra improve liver function by stimulating enzymes (proteins that speed up biochemical reactions) in the liver and promoting liver cell growth.
