According to the U.S. Food and Drug Administration (FDA), a spice is an “aromatic vegetable substance in the whole, broken, or ground form, the significant function of which in food is seasoning rather than nutrition” and from which “no portion of any volatile oil or other flavouring principle has been removed” (Gottardi et al., 2016).

Besides using spices, they are also used as colourants or dyes in cotton textiles, tobacco industries, bakery products, condiments, meat, and fish products. Even now, their usage in the preparation of Ayurvedic medicines is remarkable.
