Pellitory Root / Aqar Qarha?(???????)?also known as Longwort and Anacyclus Pyrethrum,?is widely used because of its pungent efficacy in relieving toothache and in promoting a free flow of saliva. The Pharmacopoeia directs that it be used as a masticatory, and in the form of lozenges for its reflex action on the salivary glands in dryness of the mouth and throat. The tincture made from the dried root may be applied to relieve the aching of a decayed tooth, applied on cotton wool, or rubbed on the gums, and for this purpose may with advantage be mixed with camphorated chloroform. It forms an addition to many dentifrices.

A gargle of Pellitory infusion is prescribed for relaxed uvula and for partial paralysis of the tongue and lips.

To make a gargle, two or three teaspoonsful of Pellitory should be mixed with a pint of cold water and sweetened with honey if desired. Patients seeking relief from rheumatic or neuralgic affections of the head and face, or for palsy of the tongue, have been advised to chew the root daily for several months.

Being a rubefacient and local irritant, when sliced and applied to the skin, it induces heat, tingling and redness.

The powdered root forms a good snuff to cure chronic catarrh of the head and nostrils and to clear the brain, by exciting a free flow of nasal mucous and tears.
