From Wikipedia, the free encyclopedia
Babbler's Bill, Thunbergia laurifolia, the laurel clockvine[1] or blue trumpet vine, is native to India[2] and the Indomalaya ecozone, the species occurs from Indochina to Malaysia.[3] It is locally known as kar tuau in Malaysia and rang chuet (รางจืด) in Thailand.[4]
Description[edit]
Thunbergia laurifolia leaves are opposite, heart-shaped with serrated leaf margin and taper to a pointed tip. Flowers are not scented and borne on pendulous inflorescences. The hermaphrodite flower is trumpet-shaped with a short broad tube, white outside and yellowish inside. The corolla is pale blue in colour with 5–7 petals, one larger than the others.
The plant flowers almost continuously throughout the year with flowers opening early in the morning and aborting in the evening of the same day. Carpenter bees are frequent visitors, creeping into the flowers for pollen and nectar while black ants are present probably as nectar scavengers. The plant develops a very tuberous root system.[5]
Uses[edit]
Cultivation[edit]
Thunbergia laurifolia is a popular ornamental plant in tropical gardens. It is a long-blooming vine in cultivation. Propagation is from stem cuttings or shoots from the tuberous roots. It is a fast-growing perennial herbaceous climber. It has become an exotic weed in many tropical countries.
Teas and medicinal[edit]
In Malaysia, juice from crushed leaves of T. laurifolia are taken for menorrhagia, placed into the ear for deafness, and applied for poulticing cuts and boils.[6] In Thailand, leaves are used as an antipyretic, as well as for detoxifying poisons.[7] Several Thai herbal companies have started producing and exporting rang jeud tea.[4]
Chemistry[edit]
Iridoid glucosides have been isolated from T. laurifolia.[7] Microwave-dried leaves displayed stronger antioxidant properties than fresh leaves.[4] The antioxidant properties of the infusion from microwave-dried leaves is higher than the commercial rang jeud tea from Thailand.[citation needed]
Invasive species[edit]
Thunbergia laurifolia can become an invasive species where escaping from ornamental garden uses into native habitats in supportive climates. Because it is a fast-growing perennial plant it has become an escaped exotic and noxious weed in many tropical countries The plant has become a weed found in the Cerrado vegetation of Brazil and in tropical areas of Australia.
