Domestic Encyclopædia (1802)/Supplement/Opodeldoc

OPODELDOC, a well-known liniment, which is prepared by digesting 3 parts of soap in 16 parts of the spirit of rosemary, till the former be dissolved; when one part of camphor should be incorporated with the whole.—This unguent is of great service in bruises, rheumatic affections, and similar painful complaints; but, being very volatile, it ought to be kept in bottles closely stopped, to prevent the access of air.
