herbs containing a volatile oil used to excite intestinal peristalsis and to produce an expulsion of flatus (gas).

Medicines that expel flatus from the gastro-intestinal tract and thus relieve pain produced by pressure.

The carminatives are rich in volatile oils and by their action stimulate the peristalsis of the digestive system and relax the stomach, thereby supporting the digestion and helping avoid gas in the digestive tract.
