Agni (अग्नि)

Sanskrit Verse

शान्तेऽग्नौ म्रियते, युक्ते चिरं जीवत्यनामयः। रोगी स्याद्विकृते, मूलमग्निस्तस्मान्निरुच्यते॥

— (Charaka Samhita, Chikitsasthana 15/4)

Explanation

Agni is the biological fire or metabolic energy of the body. It governs all transformation processes, from the digestion of food to cellular metabolism. When Agni is extinguished, one dies. When it is functioning optimally (Yukta), one lives a long, disease-free life. When it is deranged (Vikrute), one becomes a patient. Therefore, Agni is considered the root cause of health and disease. There are 13 types of Agni in total: 1 Jatharagni (main digestive fire), 5 Bhutagnis (elemental fires), and 7 Dhatvagnis (tissue fires).

Clinical Importance

The assessment of Agni is paramount in clinical practice. Most diseases are considered to originate from a dysfunctional Agni (Mandagni), which leads to the formation of Ama (toxins).
