White Mustard Seed and a Chronic Cough: Does it Work?

White mustard seeds, known as (Semen Sinapis Alba, derived from Brassica alba), have been used in traditional medicine to alleviate respiratory ailments. They are valued for their expectorant properties, anti-inflammatory effects, and potential to soothe hypersensitive nerves that trigger neurogenic cough. Mustard seeds are small, round seeds widely used as a spice, condiment, and medicinal ingredient. Known for their pungent flavor, they are valued for their culinary applications and potential health benefits.

White mustard seeds contain glucosinolates and myrosinase. However, unlike black or brown mustard seeds, they predominantly contain a specific glucosinolate called sinalbin. When white mustard seeds are crushed and mixed with water, sinalbin interacts with the enzyme myrosinase to produce a compound called p-hydroxybenzyl isothiocyanate, rather than allyl isothiocyanate, which is characteristic of black and brown mustard seeds.

Thus, while white mustard seeds share similar enzymatic activity with black and brown mustard seeds, they yield a different isothiocyanate compound.
