There is a saying: "Everything that is bitter to the mouth is medicine for the intestinal tract, liver, bile."
Bitter-tasting substances, drinks, herbs and vegetables increase the production and secretion of digestive juices, enzymes and bile in the stomach and intestinal tract.
Those who have regular abdominal complaints, such as bloating, are advised to take herbal teas and supplements made from: artichoke, yarrow, dandelion, fumitory, chicory, bile acids.
