Dosa is a type of thin, savory crepe made from fermented rice and lentil batter that is popular in South Indian cuisine. It is typically served with a variety of accompaniments, such as chutneys or sambar (a type of lentil-based stew). Dosa can be filled with a variety of ingredients, such as spiced potatoes, onions, or other vegetables. Vata is one of the three main doshas in Ayurveda, a system of traditional medicine that originated in India. It is believed to be associated with the elements of air and space, and is thought to be responsible for movement and communication in the body. In Ayurveda, imbalances in vata can be thought of as being caused by an excess of air and space, and can be treated with lifestyle modifications and herbal remedies. It is not clear how dosa and vata are related.
