The most common varieties are American Arborvitae (Thuja occidentalis), Japanese Thuja (Thuja standishii) and Chinese arborvitae (Platycladus orientalis).
The common name, “Arborvitae” is from the Latin, meaning “Tree of Life” and is based on the plants 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.
Like Bonsai, the trees are commonly grown along walkways into 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 sedating herbs such as Ziziphi spinosae [Sour Jujube Seed (Suan Zao Ren)] or Polygala senega [Senega Root (Yuan Zhi)] is firstly, biota seed emphasizes nourishing the heart where as sour jujube seed focuses on tonifying the liver. Secondly, biota seeds moisten dryness in the intestines while senega root astringes Yin to promote fluid production for quenching thirst.
Good quality biota seed is full, oily, and yellowish-white.
Biota seeds are used topically to treat hair loss.
