Canthium inerme, commonly known as “Woolly Canthium” or “Canthium,” is a deciduous shrub that belongs to the Rubiaceae family. This family is extensive and includes many other well-known plants, such as coffee and quinine.
Canthium inerme is valued not only for its medicinal properties but also for its ornamental value. Canthium inerme typically grows to a height of about 1 to 3 meters, though it can sometimes reach up to 5 meters.
The leaves of Canthium inerme are simple, opposite, and exude a distinctive woolly texture. They are elliptical or obovate in shape and usually measure about 4 to 12 centimeters in length. The upper surface of the leaves is green and smooth, while the undersides are covered with a dense layer of fine hairs, giving them a woolly appearance.
The small, fragrant flowers of Canthium inerme are arranged in terminal or axillary clusters. They have white or cream-coloured petals and are typically around 5 millimeters in diameter. These flowers are a source of nectar for various pollinators.
The stems of Canthium inerme are slender, branching, and covered in a layer of fine hairs. As the plant matures, the stems may become woody and develop a grayish-brown bark.
The fruit of Canthium inerme is a small, spherical drupe that starts green and matures to a purplish-black colour. Each drupe contains a single seed. These fruits are enjoyed by birds, contributing to seed dispersal.
Canthium inerme is native to various tropical and subtropical regions. It can be found in diverse habitats, including woodlands, grasslands, and savannas. It’s often seen growing along roadsides, in disturbed areas, and near water bodies.
Apart from its ornamental value, Canthium inerme has a long history of traditional medicinal use. Its leaves, bark, and other parts are employed in folk remedies for their anti-inflammatory, wound-healing, and antimicrobial properties.
The conservation status of Canthium inerme varies based on its specific geographical location. In some areas, it might be considered of least concern, while in others, it could be facing threats due to habitat loss and other environmental factors.
