Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Black salt, also known as "Kala Namak," has been used traditionally in parts of South Asia for various health purposes, including claims that it can help relieve congestion or sinus issues. This belief is rooted primarily in Ayurvedic and traditional folk medicine, where black salt is thought to have warming, expectorant, and digestive properties. Some traditional remedies suggest inhaling steam infused with black salt or consuming it as part of herbal mixtures to help alleviate symptoms of nasal or sinus congestion.

However, there is minimal scientific evidence supporting the efficacy of black salt specifically for treating or supporting sinus congestion. Most clinical and biomedical research on remedies for sinus congestion focus on saline rinses, decongestants, or established herbal medicines, rather than on black salt. The traditional rationale is that its mineral content (including traces of sulfur compounds) and supposed warming effects may contribute to a subjective feeling of relief. Nevertheless, these mechanisms have not been rigorously studied or validated in peer-reviewed scientific literature.

In summary, while black salt is recommended in traditional practices for sinus congestion, this use is not supported by robust scientific evidence, and the rating of 1 reflects the anecdotal and unverified nature of such claims.
