1. Taxonomic Insights

Species: Andrographis echioides (L.) Nees

Family: Acanthaceae

The Acanthaceae family, commonly known as the acanthus family, is a large and diverse group of flowering plants, primarily distributed in tropical and subtropical regions. This family is known for its square stems, simple opposite leaves, and showy flowers with often colourful bracts. Many members of this family, including the genus Andrographis, are valued in traditional medicine for their potent bitter principles and therapeutic properties . The genus Andrographis comprises about 40 species, most of which are native to Asia, and is characterised by its medicinal potential, particularly for liver and immune support .

Taxonomic Note: Andrographis echioides was first described by Carl Linnaeus as Justicia echioides in 1753, and later reclassified into the genus Andrographis by Nees in 1832 . The specific epithet echioides is derived from the Greek echis, meaning "viper", and the suffix -oides, meaning "like" or "resembling". This refers to the plant's superficial resemblance to species in the genus Echium (viper's bugloss), and interestingly, also hints at its long-standing traditional use as an antidote for snake and scorpion bites . The plant is an erect, branched herb with a quadrangular stem that is clothed in spreading hairs. It is distinguished from its close relative, A. paniculata, by its hairy stems and leaves, and its heteromorphic (variously shaped) leaves, which are narrower and more oblong .
