Carminative

A carminative is an herb or preparation that either prevents formation of gas in the gastrointestinal tract, or facilitates the expulsion of said gas, thereby combating flatulence.

Carminatives are often mixtures of essential oils and herbal spices with a tradition in folk medicine for this use. Examples: Anise seed (pati saunf), basil (tulsi), cardamom (elaichi), cumin (zeera), ginger (lahsun), peppermint, rosemary, thyme (hasha), etc.
