Thottea grandiflora is a species of flowering plant in the family Aristolochiaceae. It is native to Myanmar, Thailand, Peninsular Malaysia, and Singapore, where it occurs in lowland and hill forests.[1][2]
The species is a shrub that may reach about 1.2–2 m in height and is notable for its pendulous, bell-shaped flowers, which are dark claret to purple-red with pale veins and are borne near the base of the stem.[3][2]
In Peninsular Malaysia, the plant has been documented in traditional medicine, particularly the root. Modern studies have investigated its phytochemistry and potential pharmacological activity, but these findings do not establish clinical effectiveness in humans.[4]
Description
Thottea grandiflora is a shrub of lowland and hill forests. The leaves are ovate to oblanceolate, and the flowers are relatively large, pendulous, and bell-shaped with three lobes. The perianth is dark claret with pale outer veins, and the stamens are numerous and arranged in two whorls.[3]
Distribution and Habitat
The species is native to Myanmar, Thailand, Peninsular Malaysia, and Singapore.[1] It occurs in lowland and hill forests, typically up to about 600 m elevation.[2]
Traditional Uses and Research
In Peninsular Malaysia, Thottea grandiflora has been recorded in ethnomedicinal use, particularly the root, for conditions such as fever, asthma, cough, and postpartum recovery.[4] Laboratory and review studies have reported various phytochemical constituents and investigated anti-inflammatory, antimicrobial, antihyperglycemic, and antimycobacterial activity. These findings are preliminary and have not been established as effective medical treatments in humans.[4]
