What are the morphological characteristics of this plant?
Tecoma stans has woody, perennial stems that reach heights of up to 6 meters and bear pinnately compound leaves consisting of 5 to 9 leaflets. The leaflets are ovate or lanceolate in shape with serrated margins and a bright green color. Its inflorescence features clusters of bright yellow, trumpet-shaped flowers that hang from the branch tips. These flowers possess long, tubular corollas that serve to attract various pollinators like bees and hummingbirds. The plant also produces small, woody, three-valved capsules that contain numerous flat, winged seeds for wind dispersal.
What is the geographical distribution of this plant?
This plant is native to the tropical regions of Central and South America, specifically ranging from Mexico through the Caribbean and down to parts of Brazil. It thrives primarily in humid, lowland environments where warm temperatures and consistent moisture are present. Many populations are found growing in coastal areas or near river basins where the soil remains damp. Its distribution is closely tied to tropical rainforest ecosystems that support its specific growth requirements. In certain climates, it has also been introduced to other tropical zones outside of its original habitat.
How is this plant cultivated?
This plant, Tecoma stans, requires full sun exposure and well-draining soil to thrive in subtropical or tropical climates.
It grows best when planted in locations that receive at least six to eight hours of direct sunlight daily. Regular watering is necessary during the initial establishment phase, but the mature shrub is highly drought-tolerant once its root system is established. Pruning the plant in late winter or early spring helps maintain a manageable size and encourages more prolific flowering.
Because it can spread rapidly, providing ample space during planting prevents it from overcrowding surrounding vegetation.

According to a study published by "Journal of ethnopharmacology", Tecoma stans is traditionally used to treat diabetes and displays a high level of pancreatic lipase inhibitory activity. The most active fraction, TsC2F6B, consisted of a mixture of 96% Chrysoeriol and 4% Apigenin which displayed 85% inhibition when evaluated at 0.25mg/mL. Luteolin and chrysoeriol produced noncompetitive and mixed inhibition with IC50 values of 63 and 158µM respectively. The content of chrysoeriol was quantified in the hydroalcoholic extract as 1% and in the organic fraction as 7%. These results suggest that the plant could be used as a phytopharmaceutical drug standardized in luteolin, chrysoeriol, and apiigenin for Type 2 Diabetes mellitus.

What are the herbal preparations of this plant?
This plant is Tecoma stans, and its medicinal preparations include Tecoma stans infusion, hydroalcoholic extracts, aqueous extract, powders, and seed oil. The infusion and aqueous extracts are commonly prepared by steeping the leaves or flowers in hot water to release soluble bioactive compounds. Hydroalcoholic extracts utilize a mixture of alcohol and water to capture a broader spectrum of phytochemicals for therapeutic use. Dried plant parts can be processed into fine powders for topical applications or easy integration into dietary supplements. Additionally, the seed oil is extracted for its concentrated fatty acids and specific medicinal properties.
According to a study published by "Journal of ethnopharmacology", the intravenous administration of Tecoma stans infusion in normal dogs produces an early hyperglycemic response and arterial hypotension followed by a slow decrease of glucose blood values with a concomitant hypertriglyceridemia. No important changes in immunoreactive insulin were detected during the process. Heart frequency was gradually increased after the first 60 min of drug administration and persisted for several hours. The effects observed on blood parameters seem to be related to hepatic glycogen metabolism involving an activation of glycogenolysis. The late hypoglycemic effect of Tecoma stans infusion could be considered secondary to the observed hepatic glucose output.
