Safety Overview
1.Arni — Essential Profile
Clerodendrum phlomidis, commonly known as Arni or Agnimantha, is a significant medicinal plant traditionally valued across tropical and subtropical Asia, particularly in India and Sri Lanka. This resilient species thrives in arid and semi-arid environments, typically presenting as a deciduous to semi-evergreen shrub, though it can mature into a small tree, reaching heights of 1 to 5 meters.
Its classification within the Lamiaceae family, a reclassification from its historical placement in Verbenaceae, highlights its botanical relationships. The Sanskrit name 'Agnimantha' profoundly translates to 'churner of fire,' symbolizing its traditional role in igniting 'digestive fire' (Agni) and stimulating metabolic functions, alongside its historical utility in fire generation through friction.
Morphologically, Arni features woody stems with pale, often furrowed bark that develops more texture with age. Its leaves are simple, opposite, ovate to elliptic-ovate, characterized by serrated margins and a distinct venation pattern, often exhibiting slight pubescence on the underside. This adaptation aids its survival in drier climates.
The plant's robust, fibrous root system efficiently extracts moisture and nutrients from challenging soils. Arni produces distinctive, often fragrant white flowers arranged in terminal or axillary cymes. These bilabiate flowers, characteristic of the Lamiaceae family, possess prominent stamens that attract various pollinators, including butterflies and bees.
Post-pollination, the flowers yield small, globose drupes that mature from green to a dark, typically black, color, containing minute seeds. The genus Clerodendrum is extensive, encompassing approximately 500 species globally, with a strong presence in tropical Africa and southern Asia.
