Cowage seed, also known as Mucuna pruriens, has a long history of use in traditional medicine systems such as Ayurveda and Traditional Chinese Medicine (TCM). In TCM, cowage seed (often referred to as "niudou") is sometimes incorporated into formulas addressing coughs that are classified as "damp," a symptom pattern involving phlegm and internal moisture. The traditional rationale is based on the seed's reputed ability to disperse phlegm, regulate Qi, and support lung function. However, the primary uses of Mucuna pruriens in traditional medicine are more commonly related to neurological conditions and as an aphrodisiac, rather than respiratory health.

There is very little scientific evidence to support the use of cowage seed for treating cough, especially coughs associated with dampness or phlegm. Most modern research on Mucuna pruriens focuses on its L-DOPA content and the potential effects on Parkinson's disease and dopamine-related conditions. There are no clinical trials or robust pharmacological studies that specifically evaluate its efficacy in treating cough or damp-type respiratory symptoms. Thus, while cowage seed may appear in some traditional herbal formulas for cough, its use is not strongly supported by historical texts, and there is virtually no scientific validation for this indication. Its reputation for cough treatment relies primarily on traditional, anecdotal use rather than empirical evidence.
