Introduction
Cassia seed (jue ming zi) has been used in Traditional Chinese Medicine for over 1,500 years primarily for eye-health applications including 'liver heat' patterns associated with red eyes and blurred vision. The seeds are also consumed as a roasted tea throughout China and Korea.
Industrial production proceeds by hot-water or hydroalcoholic extraction of dried cassia seeds, followed by concentration and spray-drying. Roasting prior to extraction is common for tea-style applications and reduces the bitter principle.
Recognized as both food and medicine (homologous) under the Chinese regulatory framework. Approved for traditional medicine and food uses in most Asian markets; sold as a dietary supplement ingredient in the U.S. and many other jurisdictions.
The anthraquinone glycoside profile supports the traditional eye-health and liver-cooling positioning. At higher doses the anthraquinones provide mild laxative activity, which informs dosing recommendations in traditional practice.
Strategic positioning is dominated by traditional medicine and functional tea applications in Asia, with growing supplement-format uses in eye-health and liver-support categories globally.
