Bitter greens, ginger and peppermint stimulate the appetite, states HowStuffWorks. These remedies combat against poor appetites caused by anxiety, diseases, prescription and illegal drugs and poor eating habits.
Bitter greens such as collards, kale, arugula, endives, radicchio, dandelions, mizuna and sorrel increase digestion by encouraging the body to create more digestive enzymes and digestive juices, explains HowStuffWorks. It is possible to stimulate the appetite with 1/2 teaspoon of powdered ginger boiled with water to make a tea, or with ginger in the form of ginger ale or gingersnap. Another appetite stimulant is peppermint tea composed of 1 tablespoon peppermint leaves and 1 pint of boiling water. Peppermint sprigs can also be added to lemonade as an effective tea alternative.
