About Quassia Wood

Quassia Wood, known in trade as Kavasiya, is prepared from the pale yellow trunk and branch wood of Picrasma excelsa (older synonym: Picraena excelsa), a tree reaching up to 25 metres, native to Jamaica and the wider Caribbean and northern South America.

This is a single-ingredient raw material rather than a finished proprietary medicine — it is typically prepared as a mild water infusion as directed by a Vaidya, with a bill provided on every order.

Traditional Ayurvedic Importance

Unlike classical single herbs described in the Bruhat Trayi and other ancient Samhitas, Quassia Wood is a non-native botanical with no ancient Sanskrit textual lineage. It has been adopted into contemporary Ayurvedic and herbal trade practice functionally, on the basis of its markedly bitter taste — Tikta Rasa — traditionally associated with Pitta-Kapha balancing qualities when used mindfully as part of a digestive-discipline routine.

In parallel, Caribbean and Western folk-herbal traditions have long used Quassia Wood water infusions as a bitter tonic taken before meals, and externally in traditional scalp-cleansing preparations. These are traditional-use descriptions of historical record, not modern medical claims.
