Sprawled across the undulating eastern foothills of the Uva province near Bibile, Nilgala (The Blue Rock Forest) is one of the most remarkable botanical landscapes in Asia. In regional Hela chronicles, Nilgala is revered as the southeastern landing zone of the Himalayan Sanjeevani mountain—an impact that seeded an entire open forest of supreme Ayurvedic medicinal trees.
The Triphala Wonder of Nilgala
Unlike typical tropical rain forests, Nilgala is a pristine damana (talawa savanna grassland) naturally dominated by the holy triad of Ayurvedic rejuvenation: Aralu (Terminalia chebula), Bulu (Terminalia bellirica), and Nelli (Phyllanthus emblica). These three fruits form the foundational formula of *Triphala*, the supreme cleansing tonic prescribed in King Ravana's medical texts (*Arka Prakasha*).
Forest monks and local Vedda tribes attest that the wild medicinal honey collected by forest bees in Nilgala contains unique restorative properties due to the exclusive nectar of flowering Sanjeevani and Aralu blossoms.

King Buddhadasa's Royal Herbal Sanatorium
Historical stone inscriptions confirm that King Buddhadasa (4th Century CE)—famed physician king of ancient Sri Lanka who performed neurosurgery and treated animals—designated Nilgala as the royal pharmacy and medical sanctuary of the realm. Indigenous physicians were stationed here to harvest herbal bark, roots, and oils for the island's hospital network.
Massive granite boulders jutting from the savanna grasslands, known as Nilgala (Blue Rocks), display ancient meditation caves with Brahmi inscriptions overlooking the Senanayake Samudraya reservoir basin.
