It is recognized that rhubarb not only exercises a digestive action but it operates directly as a conveyer of bile salts. It can therefore be classed as a hepatic stimulant. Rhubarb performs its first digestive operation in the mouth by stimulating the taste buds with its pleasantly bitter flavor which gives a sense of cleansing out the oral cavity, preparing it to taste the coming food. When it reaches the stomach its digestive effects come into full play, causing an increase of the flow of gastric juice and inducing their movement, thus favoring the processing of the contents of the stomach. Besides stimulating the secretions from the liver which convey the bile salts, it assists the intestine in regulating the absorption of fats.
