Cannabina

Cannabina is a small genus of flowering plants within the family Cannabaceae. It is closely related to the well‑known genus Cannabis, and the two genera share a number of morphological similarities such as the presence of trichomes and a dioecious reproductive strategy. Four species have been described, the most widely recognized being Cannabina indica and Cannabina sativa, which occur in various parts of the Himalayas and Southeast Asia. The plants generally grow as herbaceous perennials or shrubs with fibrous, branching stems covered in fine hairs. Leaves are alternate, with a palmate or ternate arrangement and often exhibit a slightly glaucous surface.

Cannabina species are commonly found in disturbed habitats such as roadsides, grasslands, and forest edges, thriving in moderate elevation ranges. Although they produce resinous glands similar to Cannabis, their phytochemical profile is distinct; the dominant cannabinoids are usually present in trace amounts, and the plants are not known to possess significant psychoactive properties. Traditional uses of certain species include local medicinal practices, where decoctions or extracts are applied for their anti-inflammatory and antimicrobial effects, though scientific validation remains limited.

The taxonomy of Cannabina has been subject to revision, with molecular phylogenetic studies indicating a close relationship to the genera Humulus and Urtica. Despite its ecological presence, Cannabina has not been extensively studied for pharmacological applications. Current research focuses on its potential horticultural value as a hardy, low‑maintenance ornamental species and its role in ecosystem restoration and soil stabilization.
