Whether you have a loss of appetite due to anorexia or as a side effect of medications or medical conditions, some herbs might act as a appetite stimulant. Herbs like Gentian, Centaury, Scullcap, aka Skullcap, Ginger and Thyme might be taken to improve appetite and digestion. Bitter herbs seem to increase stomach acids and saliva, which may account for their appetite-stimulating effects.
Gentian (Gentiana lutea), also known as feltwort, bitterwort or bitterroot, is used primarily to increase the appetite in people recovering from acute diseases like dyspepsia, or painful digestion. It is a helpful herbal remedy for indigestion, heartburn, anorexia, diabetes, flatulence, distension, intestinal parasites, stomach aches and liver, pancreas and gall bladder problems. It is also good for strengthening the spleen and stimulates urine flow. By purifying the blood Gentian root extracts help to treat liver problems.
Centaury (Centaurium erythraea), is a member of the gentian family. Centaury herbal extract is used for poor appetite and anorexia accompanied by liver weakness. For anorexia, you can combine it with Chamomile and Burdock root, as well. Ginger improves appetite and gives you as much energy as a glass of energy drink. Ginger works for increasing the appetite by calming the stomach and helping with digestion by regulating the flow of stomach bile.
Thyme, Thymus vulgaris, helps to improve digestion and relax the smooth muscles in the digestive tract. You can use the herbal remedy to treat weak stomachs, cramps, diarrhea, indigestion and gas. Thyme acts as a "carminative", meaning it works to relieve the gas in the digestive tract.
Scullcap, also known as Skullcap or Scutellaria lateriflora is indicated in some studies to help for anorexia nervosa (diminished appetite). It has also been used to reduce the pain of tension headaches and to relieve anxiety and other nervous tension states.
Simply combine all herbs to make a fine tea. Equal amounts of Gentian, Centaury, Ginger, Scullcap, and Thyme, Use 1 tsp to 1 cup of hot water.
