Synopsis

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

Black pepper and white pepper have traditionally been used in various cultures, especially in South Asian medicine such as Ayurveda and traditional Chinese medicine, as remedies to help with symptoms of colds, particularly as decongestants. The warming and pungent properties of pepper are believed to stimulate circulation and help clear nasal congestion. Piperine, the main active compound in black and white pepper, is sometimes credited with mild expectorant effects, though these are not robustly substantiated in clinical trials.

Despite their long-standing traditional use, the scientific evidence supporting the effectiveness of black or white pepper as decongestants is limited. Human clinical trials evaluating their direct impact on cold symptoms or nasal congestion are lacking. Most available evidence is anecdotal or based on theoretical mechanisms, such as the irritation of mucous membranes promoting mucus clearance. Some in vitro and animal studies suggest mild anti-inflammatory or antimicrobial activity, but these findings do not directly translate into clinical benefits for treating colds in humans.

In summary, while black and white pepper have a rich history of use as supportive remedies for colds, especially as decongestants, the evidence is primarily traditional, with minimal scientific validation at this time.
