Bay rum

Bay rum ({not transcribed})

A fragrant liquid, used for cosmetic and medicinal purposes.

The original bay rum, from the West Indies, is prepared, it is believed, by distillation from the leaves of the bayberry (Myrcia acris). The bay rum of the Pharmacopoia (spirit of myrcia) is prepared from oil of myrcia (bayberry), oil of orange peel, oil of pimento, alcohol, and water.
