Recently capsicum in powder, extract, or tincture, has been recommended
internally in the treatment of incipient hemorrhoids. The dose is
.50 to 3 grams of the powder in pills or capsules; watery extract,
0.30-0.60; tincture, 10-30 drops.
The _C. annuum_, L., and other varieties of red pepper serve the same
uses as the above.
Botanical Description.--Stem 4-angled. Leaves opposite,
ovate-lanceolate, entire. Petioles short. Flowers greenish-white
in little clusters, drooping. Corolla wheel-shaped. Fruit straight,
conical, slender, scarcely 1' long.
Habitat.--Universally common in the islands. Blooms at all times.
_Datura alba_, Nees. (_D. Metel_, Roxb. and Blanco.)
Nom. Vulg.--_Talamponay_, Tag., Pam.; _Takbibung_, Vis.; _Dhatura_,
Indo-Eng.
Uses.--The applications of this species are identical with those of
_D. Stramonium_ and it is official in the Pharmacopoeia of India. It
is antispasmodic, narcotic and toxic, and is used quite commonly with
criminal intent in India and Indo-China. The cooked and bruised leaves
make an efficient poultice in articular rheumatism.
The symptoms of poisoning by "dhatura" are: dilatation of the pupil,
general malaise, dryness of the fauces and skin, hallucinations,
rapid pulse, coma and death or permanent mania.
The dry leaf is smoked to abort asthma, and though its action is
uncertain, it is one of the many remedies that should be tried,
which though ineffective in one case may in another afford positive
relief in this distressing disease. Not more than 1.50 grams should
be smoked in one day and their use should be discontinued if any
symptom of intoxication supervenes. The Pharmacopoeia of India
contains a tincture made from 75 grams of the ground seeds and 500
grams of alcohol. Dr. Waring states that 20 drops of this tincture
are equivalent to 6 centigrams of opium and that in some cases it has
given him better narcotic results than the opium. The extract is made
from 500 grams of the powdered seeds, 500 cc. ether, 500 cc. alcohol
and 500 cc. water. Dose, 5-20 centigrams a day in 4 doses.
The _D. fastuosa_, L., known in Manila by the common name of
_Talamponay na itim_, Tag., possesses the same properties as the
above. The Filipino physician, Sr. Zamora, successfully employed
a poultice of bruised leaves cooked in vinegar and applied to the
forehead and backs of the hands to reduce the fever of tuberculous
patients.
Neither the leaves nor seeds of these two varieties of _Datura_ have
been studied from a chemical standpoint, but there is little doubt
that the active principle is the _daturine_ (atropine and hyoscyamine)
that exists so abundantly in _D. Stramonium_.
