Frankly speaking if one follow ayurveda system regularly, one can never fall sick. But when we are not following the guidelines properly, we tend to fall sick.
Whatever we eat food is converted into two parts. One is healthy for body and the other is waste part. The waste part is excreted out of body and when this is somehow not excreted out of body is deposited in the body and resulted as toxins or “Aam Dosha”. Now this “Aam Dosha” is responsible for making us sick either obese, joint pains, skin disorders, heart troubles etc.
