Marayoor Sandalwood is an evergreen tree, growing up to 4-9 m tall. The trees have a long life, and may live up to one hundred years of age. The tree is variable in habit, usually upright to sprawling, and may intertwine with other species. The oval leaves are thin, oppositely arranged. It is highly valuable and becoming endangered species. Sandalwood plays an important role in the religious life of Indians.
Sandalwood oil was used traditionally to treat skin diseases, acne, dysentery, gonorrhea, and a number of other conditions. The essential oil obtained from this wood has occupied significant place in perfumery industries/market.
