Synopsis

Rating (out of 5): 2

Black salt, also known as "Kala Namak," has a long history of use in traditional Ayurvedic and South Asian medicine, particularly for digestive health, including the management of overacidity (acid reflux, heartburn, or dyspepsia). Ayurveda considers black salt as a cooling agent with alkaline properties. It is believed to counteract excess stomach acid and stimulate bile production, thus aiding digestion. The sulfur compounds in black salt are thought to contribute to its digestive effects and its characteristic flavor. However, the scientific evidence supporting these claims is limited. While anecdotal and traditional reports suggest benefits, there are few rigorous clinical studies directly investigating black salt’s efficacy in treating overacidity. Most modern research on salt and digestion focuses on sodium chloride (table salt), not black salt specifically. Some in vitro studies suggest that alkaline substances can help neutralize gastric acid, but these results cannot be directly extrapolated to black salt without further research. In summary, the use of black salt for overacidity is primarily justified by traditional practices rather than strong scientific validation. Individuals considering its use should be aware of the lack of robust clinical evidence and consult healthcare professionals for persistent or severe symptoms.
