Amboinicus

Amboinicus, also known as Indian borage, Cuban oregano, or Mexican mint, is a perennial herb in the mint family, Lamiaceae. It is native to the Indian Ocean region, particularly the island of Ambon (Ambonese), hence the name amboinicus, and is widely cultivated for culinary and traditional medicinal uses. It is commonly grown in tropical and subtropical gardens worldwide.

Description: The plant forms a bushy, fleshy shrub with opposite, hairy, fragrant leaves that are thick and oval to oblong, typically 4–8 cm long, sometimes larger. Stems are square and produce a dense clump up to 60 cm tall and wide. The aroma resembles oregano or thyme.

Taxonomy: The species has been placed in different genera, including Coleus amboinicus and Plectranthus amboinicus; current accepted name varies by taxonomic authority.

Cultivation and uses: It prefers warm climates, full sun to light shade, and well-drained soil; drought-tolerant once established; propagated by stem cuttings or layering. Leaves are used fresh or dried to season meats, stews, soups, and sauces; in Caribbean and Indian cuisines it serves as a flavoring similar to oregano. In traditional medicine, infusions and extracts are used for coughs, bronchitis, and stomach upset; essential oil contains compounds such as thymol and carvacrol.

Notes: In suitable climates it can naturalize beyond cultivation and may spread if not contained.
