Black pepper (Piper nigrum) has been used traditionally in various cultures, particularly in Ayurveda and traditional Chinese medicine, to help manage coughs, including dry coughs. The rationale in these traditional systems is that black pepper is thought to stimulate circulation, increase mucus flow, and act as an irritant that can help loosen phlegm, thereby easing cough symptoms. In Ayurveda, formulations such as "Trikatu" (a mix of black pepper, long pepper, and ginger) are prescribed for respiratory conditions, including coughs.

However, scientific evidence supporting the use of black pepper specifically for dry cough is limited. While piperine, the primary active compound in black pepper, has demonstrated anti-inflammatory and antimicrobial properties in laboratory studies, clinical trials examining its efficacy for cough relief are lacking. Most of the available evidence is anecdotal or based on traditional usage. Some home remedies combine black pepper with honey to help soothe a dry throat and potentially reduce coughing, but these are not substantiated by rigorous scientific research.

In summary, the use of black pepper for dry cough is primarily rooted in traditional medicine, with only weak or indirect support from scientific investigations. Individuals interested in trying black pepper for cough relief should consult with a healthcare provider, particularly if symptoms persist or worsen.
