Kaner, which is often referred to as Indian Oleander and is a member of the Apocynaceae family, is a genus of plants. Kaner is a tiny, evergreen tree that can reach a height of 5 meters. The leaves are whorled, long, linear-lance-shaped, and have horizontal nerves. Like flowers, leaves are also lovely.

Oleander is used to manufacture medication from its seeds and leaves. Medical applications of oleander include treating cancer, unpleasant menstrual cycles, leprosy, malaria, ringworm, dyspepsia, and venereal diseases.
