Maurice Mességué (born 14 December 1921) is a French herbalist and author of several best-selling books on herbal medicine and cooking with herbs. In his autobiography he claims to have treated, among others, Winston Churchill, Chancellor Adenauer of Germany, and the future Pope John XXIII.
He was born in Colayrac-Saint-Cirq (Lot-et-Garonne).
In 1971, he was elected the Mayor of the town of Fleurance.
Mességué practices a form of herbalism passed down through his family. Some of the practices involve, among other things, soaking the patient's feet in a strong decoction of locally gathered herbs.
