Lotus Seeds (lian zi, 莲子), also known as Lian Zi, are the mature seeds of the Lotus Plant, which is found in Middle East and Asia. These plants inhabit ponds and lakes, and its seeds are harvested in the Autumn. Lotus Seed is usually collected in August and September, after being dried in the sun and having its skin removed. Lotus Seed is usually small, round, and white or off-white in colour.

In Traditional Chinese Medicine (TCM), Lotus Seed falls under the category of ‘Herbs that stabilize and bind’. Such herbs can help to treat abnormal discharges and displacement from organs, which include conditions such as diarrhea, discharges from the vagina, penis or rectum, as well as prolapse of the uterus or rectum. Neutral in nature, Lotus Seed does not affect the yin-yang balance in the human body.

Lotus Seed also has a tonic effect on the human body as it can replenish one’s qi and blood. In particular, this herb is thought to target the Heart, the Kidneys and the Spleen.
