These flowers possess a large standard petal and a distinct keel, which are essential for attracting pollinators. The plant also features sharp stipular spines located at the base of the leaf stalks.
What is the geographical distribution of this plant?
This plant is native to the tropical regions of South and Southeast Asia, specifically ranging from India and Sri Lanka through Indochina to the Malay Peninsula. It thrives in warm, humid climates where it is frequently found in lowland areas and coastal zones. In many parts of its natural range, it has become naturalized in other tropical environments due to human introduction. It is also commonly cultivated in various subtropical and tropical gardens across the world for its ornamental value. This widespread presence is facilitated by its ability to adapt to diverse tropical soil types.
How is this plant cultivated?
This plant Erythrina variegata requires full sunlight and well-draining, loamy soil to thrive in tropical or subtropical climates.
It is typically propagated through seeds or stem cuttings during the active growing season. Because it is sensitive to frost, growers must provide protection or choose warmer regions to prevent damage to its delicate foliage. Regular watering is essential during the establishment phase, though the mature tree is relatively drought-tolerant once its root system is deep.
Pruning helps maintain its shape and encourages the production of vibrant coral-red flowers.
What parts of this plant are used medicinally?
This plant Erythrina variegata is used medicinally through its bark, roots, seeds, and wood. The bark is often prepared to treat various ailments including inflammation and fever.

It serves as an ingredient in the Mahanintangthong remedy for antipyretic purposes and the Lomammapruek remedy for analgesic and anti-inflammatory uses. The bark was extracted using 95% ethanol to study its properties. The ethanolic extract demonstrated an IC50 value of 9.27±0.72 μg/ml for inhibiting prostaglandins production through the COX-2 enzyme. Additionally, it showed an inhibitory activity against lipopolysaccharide induced nitric oxide production in RAW 264.7 cell lines with an IC50 value of 47.1±0.21 μg/ml.
