Relieve Migraine the natural way. Improper diet and lifestyle causes aggravation of Pitta (Ayurvedic term representing acid) in the body. In an aggravated state, Pitta impairs digestion, leading to production of digestive impurities (known as ama). This ama gets stored in the manovahi strotas (mind channels), thereby becoming the cause for pains in migraine. This smoothie works on Pitta and Ama.
