From ancient remedies to global spice rack
The plant's wild ancestors evolved across the tropical lowlands of East Africa, the Arabian Peninsula, and the Indian subcontinent. Indigenous peoples in these regions were among the first to recognize its culinary and medicinal properties.
In the Indian subcontinent, the plant was incorporated into the ancient systems of Ayurveda and Siddha medicine. Known as Karpuravalli in Tamil, it was used to treat respiratory ailments, digestive complaints, and skin conditions.
European colonizers and traders carried the plant along maritime routes from India and Southeast Asia to the Americas. It arrived in the Caribbean, Central America, and Mexico.
João de Loureiro formally described the species as Kalabo in Flora Cochinchinensis.
The plant appeared in herbal texts across Europe, the British Raj, and the Americas. George Bentham later transferred it to Plectranthus.
Modern phytochemical and pharmacological studies have validated many traditional uses. The plant is now the subject of hundreds of published papers.
