Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Black Pepper (Piper nigrum) and White Pepper have been used in various traditional medicine systems, such as Ayurveda and Traditional Chinese Medicine, to help support and treat symptoms of cough, including dry cough. The rationale behind their use is largely based on their warming properties and their ability to stimulate mucus flow, which can help relieve throat irritation. In Ayurveda, black pepper is a common ingredient in formulations like “Trikatu,” which is used for respiratory ailments. The pungent compounds, especially piperine, are believed to enhance circulation and promote expectoration.

However, there is limited scientific evidence to directly support the effectiveness of black or white pepper specifically for dry cough. Most available studies focus on the general anti-inflammatory, antimicrobial, and bioavailability-enhancing properties of piperine, rather than clinical effects on cough symptoms. Some anecdotal or small-scale studies suggest mild benefit, often in combination with honey or other herbs, but rigorous clinical trials are lacking. Thus, while black and white pepper have a strong basis in traditional use for cough, particularly in herbal or home remedies, scientific validation for their efficacy in treating dry cough specifically remains limited.
