Ambrette seeds come from a tropical hibiscus. The seeds contain an oil with a fatty-musky, slightly ambery odour. It's most important odoriferous components are the macrocyclic musks 5(Z)-tetradecen-14-olide and 7(Z)-hexadecen-16-olide, also called ambrettolide [6]. The oil was formerly highly appreciated in perfumery, but has now been largely replaced by synthetic musks.The seeds have a strong aroma of musk, and have been known as grani moschi. Relaxing and stimulating powers are attributed to them; and some cases, apparently authentic, have been recorded, in which they seemed to have a decided influence in casting out the poison of snakes. Possibly a further and more careful investigation of their properties, would show them to be an agreeable and useful article in cases where mild nervous prostration required a diffusible stimulant and relaxant. At present, they seem to be used for nothing beyond giving flavor to the coffee of the Arabs.
