Vincetoxicum hirsutum (formerly Tylophora ovata) is a climbing shrub known for its long stems, which can reach up to 5 metres (16 ft) and twine around other plants for support. It's used in traditional medicine, particularly in Asia, for treating respiratory conditions like asthma and bronchitis. However, scientific research on its medicinal properties is limited, and caution should be exercised. Sustainable harvesting practices should be encouraged if they are gathered from the wild.

Description

Vincetoxicum hirsutum is a climbing vine native to Eastern and Southern Asia, extending its reach across diverse habitats such as forests, mixed woods, and thickets, particularly flourishing at elevations between 200 and 1,000 metres (660 and 3,280 ft) in regions like southern China. This perennial plant, which grows up to 5 metres (16 ft) in height, showcases its botanical versatility in various soil types ranging from light sandy to heavy clay, and it thrives in both semi-shaded woodland areas and sunnier spots. With its hermaphroditic nature, Vincetoxicum hirsutum blooms from May to August, gracing its surroundings with petite star-shaped flowers in hues of yellow, pink, green, and red. The vine's evergreen leaves serve as a vital sustenance for caterpillars of the Ceylon blue glassy tiger butterfly (Ideopsis vulgaris), making it an essential component of local ecosystems.

Though primarily renowned for its medicinal properties, including antitussive, carminative, emetic, and expectorant qualities, Vincetoxicum hirsutum holds cultural significance for its therapeutic uses. Traditionally, its roots have been employed in decoctions to combat ailments such as leukaemia, asthma, coughing, traumatic injuries, rheumatoid backaches, and abdominal pains. Moreover, it has been utilized as an antidote for venomous snakebites, underscoring its role in traditional pharmacopoeias.

While its exact cultivation practices remain unknown, its contribution to traditional medicine underscores its importance in local communities. However, its status as a wild plant highlights the need for sustainable harvesting practices to ensure its continued availability.
