Peppermint Essential Oil and Digestive Upsets

"Peppermint is best known as a remedy for digestive upsets and has a beneficial action on the stomach, liver and intestines.  It is valuable in colic, diarrhoea, indegistion, vomiting and stomach pain because of its antispasmodic action which will relieve the smooth muscles of the stomach and gut.  Use it, well diluted, to massage the stomach and abdomen in a clockwise direction.  Drinking Peppermint tea augments the effects of massage."
Davis, P. Aromatherapy an A-Z, (2000), p. 233
