Cerbera odollam Gaertn

MEDICINAL PROPERTIES
The fruit, when still green, looks like a small mango, with a green fibrous shell enclosing an ovoid kernel measuring approximately 2 cm × 1.5 cm and consisting of two cross-matching white fleshy halves. On exposure to air, the white kernel turns violet, then dark grey, and ultimately brown, or black. The plant as a whole yields a milky, white latex. Cerbera odollam bears a close resemblance to the Oleander bush, another highly toxic plant from the same family.
The fruits are used for manufacturing bioinsecticides and deodorants. Investigations have also been made into the feasibility of converting the seeds into biodiesel.
All parts of the plant are poisonous. The Bark, Leaves, Fruits, Latex of the Othalam is used for rabies, skin diseases and ringworm.
