What is schizandra(Wu Wei Zi)? Actually there are two kinds of schizandra berries that are commonly used medicinally. They are the ripe fruits of Schisandra chinensis (Turcz.) Baill. or Schisandra sphenanthera Rehd. et Wils. Both of them are plant species of family Magnoliaceae. In China the former one is better known as "North schizandra" since it is mainly produced in the Northeast; the latter is better known as "South schizandra" since they are mainly from the southwest and south of the Yangtze River. And the south one is typically believed with better medicinal properties. Other common names include Schisandra Fruit, Schisandra Seed, Five Taste Fruits, Five Flavors Fruit, and more. Medicinally they are collected in fall when the fruits are ripe. And then they are just needed to be dried in the sun. It is normally used raw or steamed with vinegar and honey.

As its name implies, it is a berry that is with 5 kinds of flavors – spicy, sweet, sour, bitter, and salty. This makes it easily stand out from the rest herbs that are usually with 1 or 2 flavors. Thanks for that, it helps play an important role in balancing the relationship of five internal organs.
