Suruhanas were traditional healers on Guam who were highly respected. They used herbal medicines and spiritual techniques to treat illnesses, believing that diseases could be caused by spiritual or natural causes. Some key herbal medicines mentioned include extracts from the nunu tree to stop bleeding, and teas made from hagon leaves, hale roots, and lasas bark to treat fevers. Suruhanas would also use techniques like herbal ointments, mystical ashes, and the urine of firstborn males in their healing practices. The role of modern suruhanas is to promote traditional medicines and customs.
