The plant today

Coleus amboinicus is a species of semi-succulent perennial plant in the family Lamiaceae. It has a pungent oregano-like flavor and odor. Coleus amboinicus is considered to be native to parts of Africa, the Arabian Peninsula, and India, although it is widely cultivated and naturalized elsewhere in the tropics where it is used as a spice and ornamental plant. Common names in English include Indian borage, country borage, French thyme, Indian mint, Mexican mint, Cuban oregano, broad leaf thyme, soup mint, Spanish thyme. The species epithet, amboinicus refers to Ambon Island, in Indonesia.

Uses

The fleshy, aromatic leaves of this plant are bruised and applied locally for the bites of centipedes and scorpions. They are also applied to the temples and forehead for headache, held in place by a bandage. In Cochin China they are used in asthma, chronic bronchitis, epilepsy and other convulsive diseases. The juice of the leaves is a carminative and is given to children suffering with wind colic. Dr. Wight claims to have observed occasional intoxicating effects following its use, but Dymock states that he has never observed such effects. The plant contains a coloring matter, colein (C10H10O3), red, insoluble in ether, soluble in alcohol, slightly soluble in water. On the addition of ammonia the solution changes to purple, then violet, indigo, green, and, finally, greenish-yellow.

Another species, the C. atropurpureus, Benth. (C. grandifolius, Blanco), well known in the Philippines by its common name mayana, is used in the treatment of bruises, the bruised fleshy leaves being the part employed; these leaves are downy and dark violet in color.
