The best method of application is by rubbing in a small quantity of the aconitine ointment until numbness is felt, but the costliness of this preparation causes the use of the aconite liniment to be commonly resorted to.
From the root of Aconitum Napellus are prepared a liniment and a tincture.
The British Pharmacopoeia contains a watery solution - the Aqua Chloroformi - which is useful in disguising the taste of nauseous drugs; a liniment which consists of equal parts of camphor liniment and chloroform, and is a useful counter-irritant; the Spiritus Chloroformi (erroneously known as "chloric ether"), which is a useful anodyne in doses of from five to forty drops; and the Tinctura Chloroformi et Morphinae Composita, which is the equivalent of a proprietary drug called chlorodyne.
The external uses of the drug are mainly analgesic. The liniment or plaster of belladonna will relieve many forms of local pain.
