Revered across South and Southeast Asia for its bold, spicy, and clove-like flavor with a distinct peppery bite that is more intense than both sweet and Thai basil. It is the star of Thailand's beloved pad kra pao (Thai basil stir-fry with meat and chilies), and is widely used in Ayurvedic medicine as a powerful adaptogen. Brew fresh leaves into a calming herbal tea or add to curries and stir-fries for an aromatic, medicinal depth. Holy basil has been extensively studied for its adaptogenic, anti-stress, antimicrobial, and immune-boosting properties, and is rich in vitamins A, C, and K.
