Gentian is a bitter gastric stimulant. It was used for conditions such as anorexia, lack of appetite, and Stomach Upset. It was also very useful in malnourished individuals in the elderly population.
Gentian is one of the bitterest substances known to man and begins to work as soon as it is absorbed in the mouth. It stimulates the taste buds and the stomach to produce saliva and gastric juices. This stimulates the appetite. Gentian also causes the stomach to empty faster and improves gastric muscle tone. This allows food to be more easily digested.
