Tecoma stans (L.) Juss. ex Kunth (= Tecomella stans Seem)

Names.

Myanmar: sein-takyu. English: trumpet-bush, yellow-bells, yellow-elder, yellow trumpet-bush.

Range.

New World tropics.

Uses.

Bark: Utilized as an antisyphilitic and as an antidote in alcohol poisoning. Leaf: Used for hypoglycemic properties.

Notes.

Reported uses of the species include stomachache, alcoholism, atony, biliousness, diabetes, diuretic, dysentery, gastritis, inappetence, indigestion, intoxicant, pain, stomachic, syphilis, tonic, and vermifuge ( Duke 2009). In India the root is used to treat scorpion sting; also snake and rat bite ( Jain and DeFilipps 1991).

Pods of T. stans have been shown to contain tecomine and tecostanine, which have the effect of lowering blood sugar levels ( Lan et al. 1998). Research has provided evidence that the main antidiabetic effect of the aqueous extract is due to intestinal a-glucosidase inhibition by decreasing the postprandial hyper-glycaemia peak. Additionally, the aqueous extract sub-chronic administration was found to reduce triglycerides and cholesterol without modifying fasting glucose ( Anguilar-Santamaría et al. 2009).
