Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Hyacinth bean (Lablab purpureus) has a history of use in traditional medicine systems, particularly in Chinese herbal medicine, where it is known as "Bai Bian Dou." In traditional Chinese medicine (TCM), hyacinth bean is sometimes included in herbal formulas intended to address symptoms such as cough, especially when related to dampness or digestive weakness. However, while its traditional uses are well-documented for digestive ailments, there is limited direct historical evidence supporting its use specifically for cough as a primary indication. Most references to its use for cough are indirect, stemming from its general role in strengthening the spleen and eliminating dampness, which, according to TCM theory, could secondarily help resolve coughs associated with these imbalances.

On the scientific side, there is little to no modern clinical research evaluating the efficacy of hyacinth bean in treating cough. The available scientific studies focus mostly on its nutritional content, antioxidant properties, and other potential health benefits, but not on respiratory symptoms or cough relief. Thus, its rating is low due to a lack of direct supporting evidence, and its use for cough remains primarily rooted in traditional practice rather than robust scientific validation.
