, thus flowers on a female plant will only produce fruit when fertilized with pollen from a male plant. However, there is a hybrid selection titled "Eastern Prince" which has perfect flowers and is self-fertile. Gardeners should beware that seedlings of "Eastern Prince" are sometimes sold under the same name but are typically single-sex plants.

Etymology

Its Chinese name comes from the fact that its berries possess all five basic flavors: salty, sweet, sour, pungent (spicy), and bitter. Sometimes it is more specifically called běi wǔ wèi zi (; literally "northern five flavor berry") to distinguish it from another traditionally medicinal schisandraceous plant Kadsura japonica

Traditional uses in Russia

The great interest in Limonnik (Schisandra chinensis) in Russia arises from results of ethnopharmacological investigations of Russian scientists in the Far East regions where the berries and seeds were used by Nanai (Goldes or Samagir) hunters to improve night vision, as a tonic and to reduce hunger, thirst and exhaustion since “it gives forces to follow a sable all the day without food”

Medicinal Uses

"Pharmacological studies on animals have shown that Schizandra increases physical working capacity and affords a stress-protective effect against a broad spectrum of harmful factors including heat shock, skin burn, cooling, frostbite, immobilisation, swimming under load in an atmosphere with decreased air pressure, aseptic inflammation, irradiation, and heavy metal intoxication.
The phytoadaptogen exerts an effect on the central nervous, sympathetic, endocrine, immune, respiratory, cardiovascular, gastrointestinal systems, on the development of experimental atherosclerosis, on blood sugar and acid-base balance, and on uterus myotonic activity."

Chemistry

Schizandrin is one of the main dibenzocyclooctadiene lignans present in the fruit of Schisandra Chinensis. Biological activities including hepatoprotective, antiviral and neuroprotective effects of schizandrin and other dibenzocyclooctadiene lignans have been reported.

Recent studies have demonstrated that schisandrin exhibits anti-oxidative effects in vivo.
