The Story behind Biota Seed Extract
Semen Biotae, also known as Biota Seed or Bai Zi Ren, is classified as a superior herb in the Shennong Ben Cao Jing, one of the oldest and most revered texts in Traditional Chinese Medicine (TCM). Historically used for calming the mind and lubricating the intestines, it offers a rare “dual-regulation” effect on both the nervous and digestive systems.
As early as the Eastern Han Dynasty, it was included in classic formulas from the Treatise on Cold Damage (Shang Han Lun) for treating insomnia, forgetfulness, restlessness, and dry constipation. Its name comes from the plant it is derived from — the Chinese Arborvitae (Platycladus orientalis). The kernels are smooth, aromatic, and considered part of both the medicine and food continuum.
