Schizandra Berry is believed in Traditional Chinese Medicine to be the most complete herb, possessing all five natural flavours, sour, sweet, salty, bitter and spicy. Chinese Medicine professes that all foods have one or several of the five flavours, each which have their own benefit to the body. Schizandra contains all five flavours. Schizandra Berries have been used for thousands of years to promote the health of the skin, cleanse the liver, improve cognitive function and reduce stress. In Traditional Chinese Medicine, it is said that Schizandra can "calm the heart and quieten the spirit". This Schizandra is a 10:1 concentrate from the North Of China, in the high altitude mountains. Over 10 pounds of Schizandra Berries are collected and concentrated into one pound of extract for you to consume immediately.
