Impaired digestion at the tissue level produces excess waste products or Ama (toxic remains in the body due to improper digestion). This causes accumulation of bad cholesterol and blockage in the blood vessels. Kalonj and its oil helps to improve Agni (digestive fire) and reduce Ama. This is due to its Deepan (appetizer) and Pachan (digestive) properties.
