Description of Cyperus scariosus:
A delicate, slender sedge. The plant produces deep brown tubers
with aromatic odor.
Steam distillation of the tubers yields 0.075-0.080% of an
essential oil (Basu, loc. cit.).
Intravenous administration of hydro-methanolic extract of
C.scariosus (3-10mg/kg) produced hypotensive and
bradycardiac effects. These effects remained unaltered in
atropinized animals indicating that cardiovascular effects of
the plant extract are not mediated through activation of
muscarinic receptors. In the in vitro studies, it
suppressed the spontaneous contractions of guinea-pig paired
atria, rat uterus and rabbit jejunum in a
concentration-dependent (0.1-1mg/ml) manner. It also inhibited
histamine or acetylcholine-induced contractions of guinea-pig
ileum indicating non-specific spasmolytic action. In rabbit
aorta, it inhibited norepinephrine (10 micro M) as well as K+
(80mN)-induced contractions at similar concentrations
(0.1-1mg/ml). C.scariosus has been reported to contain
Ca2+ channelblocker-like constituent(s), which explained
hypotensive effect observed in vivo and the general spasmolytic
activity of plant explains its folkloric use in diarrhea.
The oil of C.scariosus roots was found to have potent
anti-inflammatory activity in a dose of 100mg/kg
intraperitonially in rats against carrageenan-induced edema,
adjuvant arthritis and cotton pellet-induced inflammation. The
activity of the extract was comparable with phenylbutazone
100mg/kg orally and hydrocortisone acetate 5mg/kg,
intraperitonially. The activity was found to be comparable to
that of hydrocortisone acetate.
The tubers are credited with astringent, diaphoretic, diuretic,
dessicant, cordial and stomachic properties. A decoction of the
tuber is used for washing hair, treating gonorrhea and syphilis.
It is also given in diarrhea and for general weakness.
