What is White Peony Root (Bai Shao)?

White Peony Root (bai shao, 白芍), also known as Semen Ziziphi Spinosae, are the peeled roots of the plant Paeonia lactiflora. This herb is obtained by digging the roots of a three to four years old Paeonia lactiflora in the summer or autumn, which is then washed, cooked in warm water and dried under the sun. The word ‘Peony’ is derived from the Greek name ‘Paeon’, referring to the physician of the Gods, reputed to have discovered the medicinal properties of plants in this genus.  

White Peony Root has been cultivated since 900 BC, and is widely grown in China provinces such as Zhejiang, Anhui and Sichuan. In the West, Peony petals can be dried and used in potpourri or to scent baths with. On the other hand, in China, White Peony petals are parboiled and sweetened for use as a tea-time delicacy, topping in summer salads, jams, or as a garnish in drinks. In Chinese culture, it is said that ladies who consume White Peony Root tea on a regular basis will become as radiant and beautiful as the flower itself.

In Traditional Chinese Medicine (TCM), Bai Shao falls under the category of ‘Tonic herbs for Blood Deficiency’. Such herbs are used for patterns of Deficiency to replenish one’s ‘Four Treasures’ (qi, blood, yin, yang). Neutral in nature, Bai Shao does not affect the yin-yang balance in your body.
