Schizandrin B--one of the hottest products in November

Plant source:the seeds of Schisandra chinensis (Turcz.) Baill

Schisandra chinensis (common name: magnolia-vine, Chinese magnolia-vine, schisandra), whose fruit is called magnolia berry or five-flavor-fruit, (from Chinese wu weizi) is a deciduous woody vine native to forests of Northern China and the Russian Far East. It is hardy in USDA Zone 4. The plant likes some shade with moist, well-drained soil. The species itself is dioecious, thus flowers on a female plant will only produce fruit when fertilized with pollen from a male plant. However, a hybrid selection titled 'Eastern Prince' has perfect flowers and is self-fertile. Seedlings of 'Eastern Prince' are sometimes sold under the same name, but are typically single-sex plants.
