The seeds contain glycosides derived from the cardenolides tanghinigenin and digitoxigenin, such as cerberin, neriifolin, thevetin B and 2’-O-acetyl-thevetin B. The principal cardenolides contained in the bark and roots are gentiobiosyl-thevetoside and glucosyl-thevetoside along with other thevetosides derived from tanghinigenin. The amount of cardenolides in the leaves varies according to the season. Some of the cardenolides showed antiproliferative activity against human colon cancer, breast cancer, lung cancer and epidermoid carcinoma cell lines, as well as anti-oestrogenic activity. Cerberin acts on plain muscle preparations as a definite stimulant both with regard to tone and peristaltic movements. As such it behaves as a parasympatomimetic poison. It acts on both the rhythm and amplitude of the heart. In moderate doses cerberin has positive inotropic properties, but in high, toxic doses it produces a negative inotropic and chronotropic effect. Phytochemical investigations also revealed the presence of a series of lignans derived from olivil (cerberalignans) and monoterpenoids such as cerberidol. Ethanolic extracts of Cerbera manghas have shown selective activity against vesicular stomatis virus (VSV). Olivil, carinol and cycloolivil showed antioxidant activities.
The wood is lightweight to medium-weight, with the white to pale yellow-brown heartwood not demarcated from the sapwood; grain is straight to slightly interlocked, texture fine and uneven. The shrinkage upon seasoning is moderate, and the wood works easily. It is not durable, highly susceptible to blue-staining fungi, and resistant to preservative treatment under pressure.

Medicinal Uses:
Used much like digitalis.
The seeds of Cerbera manghas are used in traditional medicine in Madagascar to treat cardiac disorders. However they are very poisonous and were used until the middle of the 19th century as ordeal poison. In tropical Asia the seeds are used to treat scabies and itch, to prepare a hair tonic and as fish poison, the bark is used as a laxative and antipyretic and in the treatment of dysuria and ringworm, the flowers to treat haemorrhoids, and roots, bark and leaves to prepare a purgative.

Other Uses:
In Sri Lanka, this wood is used for making masks particularly because it is a light wood. The wood is also used in tropical Asia for mouldings, interior trim, fruit cases, core veneer, matches, shuttering, clogs, plain furniture and carving, and also for charcoal. Cerbera manghas is planted as an ornamental and the fibrous fruits, of which the skin and soft parts have decayed, are used in flower arrangements.

Mythology:.…….Because of its deadly poisonous seeds, the genus name is derived from Cerberus, the hell dog from the Greek mythology, thus
indicating the toxicity of the seeds. In Madagascar, the seeds were used in sentence rituals to poison kings and queens.

Known Hazards: ……Poison….The leaves and the fruits contain the potent cardiac glycoside cerberin, which is extremely poisonous if   ingested.
