1. The Story Behind White Hyacinth Bean Extract
White Hyacinth Bean (Lablab purpureus), known as “Bai Bian Dou” in Chinese, has been used in traditional Chinese medicine (TCM) for centuries as a mild yet effective tonic.
It was first recorded in Shennong Ben Cao Jing as a “superior herb that strengthens the spleen and resolves dampness.” During the Ming Dynasty, Li Shizhen described it in the Compendium of Materia Medica as “sweet, mild, and non-toxic, suitable for long-term consumption.”
Historically, White Hyacinth Bean was both a food and medicine — added to congee or soups to aid digestion and prevent summer heat illnesses. Today, its extract is recognized for gut health, immune balance, and gentle energy restoration.
2. The Botanical Characteristics of White Hyacinth Bean
