Terminalia chebula (Haritaki): The “King of Medicines” for Gut, Brain, and Longevity
Terminalia chebula, widely known as Haritaki, is one of the most esteemed herbs in Ayurvedic medicine, referred to as the “King of Medicines” (Kayastha). Celebrated for its potent rejuvenating, digestive, and detoxifying properties, Haritaki supports a wide spectrum of body functions, from regulating bowels and nourishing the nervous system to promoting longevity and clarity of mind.
It is one of the three constituents of Triphala, along with Amalaki and Bibhitaki, and holds a special place in Rasayana therapy for its holistic actions on all three doshas, Vata, Pitta, and Kapha.
What is Haritaki?
Haritaki is a medium-to-large deciduous tree that produces oval, greenish-yellow fruits, which are collected, dried, and used for their medicinal benefits. The dried fruit is highly revered in Ayurveda, Siddha, Unani, and Tibetan medicine as a restorative and longevity-promoting agent.
Haritaki is classified as Rasa Panchaka, having five out of six tastes (all except salty), a unique quality in Ayurveda. It balances all doshas, but is especially effective in Vata-related disorders, digestive sluggishness, and neurological fatigue.
