the root is the medicinal portion pyrethri radix^ in the form of
cylindrical, wrinkled pieces, of the size of the little finger, hard
and brittle, which, when dried, have little or no odor. Exter-
nally, it is of an ash-brown color, within white, and possesses an
extremely acrid taste, with a burning and tingling sensation over
the whole mouth and throat, which continues for some time, and
excites a copious flow of saliva.
Medical Properties and Action.—Pyrethrum root is an irritant
and sialogogue, and when it is rubbed on the skin it causes much
irritation, and may even excite inflammation.
Its activity depends upon an acrid oil and a compound resin
called pyrethrin. It is rarely used internally, and only as a
masticatory.
Therapeutic Uses.—Pyrethrum has been employed as an exci-
tant in paralysis of the tongue and muscles of the throat, relaxed
sore throat, spontaneous salivation, certain forms of headache -,
for such purposes being chewed, or employed in the form of a
gargle, in tincture or decoction.
Dose.—Of pyrethrum as a masticatory, gr. xv to 5j- Tinctura
Pyrethri^ Tincture Pyrethrum, is composed of pyrethrum Siv,
rectified spirit Oj.
Dental Uses.—Pyrethrum has been employed in dental practice
for neuralgic affections of the face, for which it is chewed ; for
the relief of odontalgia, in the form of the tincture applied to
the irritable pulp on a pellet of cotton ; as a stimulant to the
gums and mucous membrane of the mouth in relaxed conditions
for obtunding sensitive dentine, in the form of a strong alcoholic
extract. The ethereal oil of pyrethrum is recommended as a
pleasant and efficacious remedy in odontalgia, applied in the same
manner as the tincture ; the fluid extract is also employed as an
ingredient for local anaesthetic preparations, combined with chloro-
form, ether and lavender, etc. (See Chloroform.)
