Black pepper (Piper nigrum) has a long history of use in traditional medicine systems such as Ayurveda and Traditional Chinese Medicine (TCM) for managing respiratory ailments, including congestion. In these traditions, black pepper is valued for its warming properties and its ability to stimulate circulation and mucus flow. It is commonly used in home remedies for colds and coughs, often combined with honey or other herbs, to help clear nasal passages and relieve chest congestion.

From a scientific perspective, the primary active compound in black pepper, piperine, has demonstrated some anti-inflammatory and expectorant properties in laboratory studies. Some research suggests that piperine may stimulate the respiratory tract and help break down mucus, potentially aiding in the relief of mild congestion. However, these effects have mostly been observed in animal models or in vitro studies, and well-designed human clinical trials are lacking.

Overall, while there is a strong traditional foundation for using black pepper to support relief from congestion, scientific evidence is limited and not robust. The remedy is generally considered safe in culinary amounts, but may cause irritation in sensitive individuals. As such, black pepper may be used as a complementary approach for mild congestion, but should not replace medical treatment for serious respiratory conditions.
