Synopsis

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

Pepper, particularly black pepper (Piper nigrum) and sometimes cayenne (Capsicum spp.), has a long history of traditional use for relieving cold symptoms, especially as a decongestant. In various traditional medicine systems, including Ayurveda and traditional Chinese medicine, pepper is believed to help clear nasal passages and support respiratory health. This effect is often attributed to the pungent compounds found in pepper, such as piperine in black pepper and capsaicin in chili peppers, which can irritate mucous membranes and trigger a temporary increase in mucus flow or sneezing, potentially clearing nasal congestion.

However, scientific validation of pepper's efficacy as a decongestant is limited. Studies on capsaicin (primarily from chili peppers) have shown some benefit when applied intranasally for non-allergic rhinitis, but evidence for oral consumption of black pepper or its use as a remedy for common cold congestion is sparse and not robust. Most claims are based on anecdotal reports or traditional practices rather than controlled clinical trials. The warming or stimulating sensation from consuming pepper may provide subjective relief, but this has not been rigorously quantified. Therefore, while pepper continues to be used traditionally for cold symptoms, scientific support remains minimal, justifying a low evidence score.
