Camphorated Spirit of Wine.
Dissolve an ounce of camphor in a pint of rectified spirits.
This solution is chiefly employed as an embrocation in bruises, palsies, the chronic rheumatism, and for preventing gangrenes.
The above quantity of camphor, dissolved in half a pound of the volatile aromatic spirit, makes Ward's Essence.
