Biota Seed (Platycladus orientalis/Bai Zi Ren) is not to be confused with Biota Leef (Ce Bai Ye). The seeds are known for their calming and sedating properties while the leaves are known for Cooling the Blood and Stopping Bleeding. In TCM (Traditional Chinese Medicine), the seeds are also said to Open the Heart.

The most common varieties of biota trees are American Arborvitae (Thuja occidentalis), Japanese Thuja (Thuja standishii), and Chinese Arborvitae (Platycladus orientalis). It is the Chinese variety that is used medicinally.

The common name, “Arborvitae” is from the Latin, meaning “Tree of Life” and is based on the plant’s association with long life and vitality in Buddhist thought. The tree is famous for its unchanging evergreen nature in cold dry climates of Northwest China and for living to be thousands of years old.

In TCM, the seeds are often combined with Wild Asparagus Root (Tian Men Dong) and Reishi (Ling Zhi) further supporting their ability to calm and aid digestion.

In China, the tree is associated with long life and vitality. The wood is used in Buddhist temples both for construction work and as incense for burning during ceremonies.

Like Bonsai, the trees are commonly grown along walkways in shapes and designs or as a privacy fence. In the wild, they can grow to be 45 feet tall.

The difference between biota seed and other commonly used sedating herbs, such as Sour Jujube Seed (Suan Zao Ren) Ziziphi spinosae and Senega Root (Yuan Zhi) Polygala senega is that biota seed emphasizes Nourishing the Heart, while sour jujube seed focuses on Tonifying the Liver, and biota seed Moisten Dryness in the Intestines, while senega root is said to Astringe Yin and Promote Fluid production for quenching thirst
