Preparations made from parts of this tree are used to control coughs and leprosy, stimulate weight gain, alleviate indigestion, treat eye and ear ailments, promote urinary flow, resolve liver and intestinal problems, and eliminate bad breath.
Sap: Applied topically to make the body feel light and agile.
Wood: Grated and used in various preparations, both external and internal, especially for illness during and after childbirth, but also to treat rheumatism, smallpox, abdominal illnesses, and other body pains; additionally, used as a cosmetic. The scented wood is employed as a stimulant, tonic, and carminative. It is also a constituent of medicine for heart palpitation, and other illnesses. Inner wood is made into a paste which is inhaled, or burned to produce fumes for inhaling as a remedy for excessive dizziness; applied topically or ingested to cure vomiting, stop bleeding, and alleviate swollen joints; and applied at frequent intervals as a remedy for skin disorders and conditions arising from lack of hygiene. The paste, mixed with the root bark from kyet-hsu (Ricinus communis), is applied topically to alleviate stomachaches; ingested to treat asthma and vomiting; made from the wood of the black akyaw variety, is mixed with oil and applied topically to cure shooting stomach pains. The wood powder- mixed with honey, and ingested by licking, is considered a cure for heart disease and long-lasting fevers; rolled in thanat-pet (Cordia dichotama) leaves and smoked like a cigarette or in a pipe, is used to strengthen the heart and stomach. To stimulate proper healing, a mixture of the wood and sap from Oh-htane-pin (the scientific name of this plant could not be ascertained per Thi Thi Ta, personal communication) is placed on embers to produce smoke directed toward sores that have not healed, infected sores, and sores infested with maggots.
