, toxins are known as ama. It is the undigested food that is fermented and collected in the stomach, as per Ashtanga Hrudaya
Ama creates intestinal fermentation and imbalances the Tridoshas and is the main cause of all disease. It is in the form of Kapha, which is sticky, heavy, viscous, slimy, unctuous, wet, cold, sweet, causing blockage of the channels, and stagnation.
