When we are sick, we lose our sense of taste and our appetite. Taste, appetite, and power of digestion are related. Lack of taste indicates fever, disease, low agni, and high ama. To improve agni and eliminate disease, it is necessary to improve our sense of taste. This is why spices are such important ayurvedic herbs. Desire for tasty food indicates hungry agni or disease. The problem is that we have perverted our sense of taste with artificial substances.
