Physical systems such as weakened digestion, leading to excess abdominal gas, persistent indigestion, and poor appetite can be relieved due to the stimulatory effect of gentain on the digestive system. The active absorption of nutrients in the stomach is also increased by this improvement in the secretion of the stomach - a general improvement in digestion is induced by the herb. A stimulatory effect on the gallbladder and liver is also observed when gentian is used. Older people are often advised to take gentian as a digestive tonic. Gentain is the preferred herb for use in cases of iron-deficiency anemia - which is almost always a result of heavy bleeding due to other problems. Women affected by heavy and excessive menstrual bleeding are often given gentian along with their other prescriptions for this reason.
