Safety Overview
1.Clerodendrum — Essential Profile
Clerodendrum serratum (L.) Moon, widely recognized as Bharangi in various traditional Indian medical systems, is a robust perennial shrub belonging to the Lamiaceae family, though historically it was classified under Verbenaceae. This species typically grows to a height of 0.5 to 1.5 meters, occasionally exceeding this in optimal conditions. Its morphology is distinctly appealing, featuring ovate to elliptic-oblong leaves that range from 10 to 20 cm in length and 4 to 10 cm in width. The leaves exhibit a lustrous, dark green upper surface and a paler underside, with prominent serrated margins and a clearly visible reticulate venation pattern, contributing to its unique texture.
The plant's striking inflorescence consists of terminal or axillary panicles adorned with tubular flowers. These blossoms typically display delicate hues of white, pale blue, or lavender, characterized by a campanulate (bell-shaped) calyx and a corolla divided into five distinct lobes. The prominent stamens and pistil often extend elegantly beyond the corolla, attracting a variety of pollinators like bees and butterflies, essential for its reproduction. The stem of Clerodendrum serratum is initially green and slightly hairy, gradually maturing into a more woody, fibrous, and often quadrangular structure.
Its extensive fibrous root system is crucial for anchoring the plant and nutrient absorption, and is a primary source of its medicinal compounds. Post-pollination, the plant produces small, globose drupes that transition from green to a deep blue or black upon ripening, typically containing one to four seeds. This species thrives in tropical and subtropical regions, particularly across Africa, Southern Asia, Malaysia, and is widely distributed in the forests of India and Sri Lanka, preferring moist, well-drained soils.
