Cassia Seed
Named for its vision-clarifying power — Cassia Seed cools Liver heat, brightens the eyes, and gently moves the bowels for a clear, vital, and unobstructed body.
What Is Cassia Seed?
Cassia Seed (Jue Ming Zi, 决明子) is one of the most beloved vision-supporting herbs in Traditional Chinese Medicine. The small, shiny seeds of Senna obtusifolia have been used for over 2,000 years specifically for their affinity with the eyes and the Liver — the organ most intimately connected with vision in TCM.
Bitter, sweet, and slightly cold in nature, Cassia Seed enters the Liver, Large Intestine, and Kidney channels. Its bitter-cold nature clears Liver heat that rises to disturb the eyes, while its sweet quality gently nourishes. A secondary action on the Large Intestine makes it effective for heat-type constipation. Today it is one of the most popular herbs in wellness teas and daily tonic preparations across East Asia.
History & Origin
Cassia Seed has been a cornerstone of eye-care herbal medicine in China since the Han Dynasty, remaining one of the most used herbs for eye health and Liver fire in TCM practice today.
