Agni : Your Digestive Fire


Agni in Sanskrit means fire. In Ayurveda principles, Agni is the digestive and metabolic "fire" produced by the doshas that grabs the essence of nourishment from nutrition (food), emotions, and thoughts and transforms it into a form your body can utilise.

Agni helps various tissues of the body produce secretions, metabolic reactions, and other processes needed to create energy, maintain and repair the body.

Agni is also responsible for the immune system since its heat destroys harmful organisms and toxins which may otherwise affect our health. The activity of agni varies throughout the day and maintaining the strength and natural ebb and flow of your digestive fires is needed for good digestion, good immune function, and resistance to disease.

When agni is healthy there is excellent digestion, normal elimination of wastes, proper tissue formation, good circulation of nutrition, high energy, strong immunity, and good mental and physical health. When agni is unhealthy, digestion is inefficient and incomplete and all the essential functions of body are disturbed. Most importantly, when agni is disturbed, incompletely digested food form an internal toxin known as ama. Ama can further putrefy within the intestinal tract and can spread throughout the body to cause diseases. Thus Agni is most important in keeping a person fit and healthy.

There are thirteen forms of agni, the most important of which are:
  • jatharagni, (regulates and contributes a part of itself to the other agnis). Sometimes jatharagni is referred to as kosthagni (Kostha=digestive tract) or pachakagni (Pachana=cooking). The main function of jatharagni is to cook the ingested food and separate the sara (nutrients) from the kitta (waste). The sara is also known as ahara rasa which is the substrate for the first bodily tissue, rasadhatu.
The other twelve agnis:
  • are the dhatagnis (7) and the bhutagnis (5), which are related to the body tissues and the five elusive elements, respectively. The dhatagnis regulate the physiological processes in each of the seven tissues, while the bhutagnis regulate the further digestion and assimilation of the pancha mahabhuta contained in the ingested foods.
Factors which disrupt agni:
The Ayurvedic writings by our ancient pious people (sadhus, rishis, & munis) classify the factors which may disrupt agni. These factors include:

  • eating at inappropriate times
  • overeating
  • undereating
  • eating devitalized foods
  • eating before the previous meal has been digested
  • excessive sleep
  • anger
  • grief
  • immoral behavior
  • consumption of excess fluids
  • frequent changes in dietary habits.
