Antiarrhythmic effect
Water extract and total coumadin from fructus cnidium have obvious preventive effects on chloroform
induced ventricular fibrillation in mice and calcium chloride induced ventricular fibrillation in rats. Fructus
cnidium and zanthoxylum acetaminophen also have this pharmacological effect and can improve ventricular
electrofibrillation threshold in rabbits. The water extract, total coumarin, cnidium, and phenols of zanthoxylum
had significant inhibitory effects on the flow of sodium ions in the myocardial cell membrane.
Antihypertensive, inhibition of vascular dilatation
Osthol had a dose-dependent negative inotropic effect on the left atrium of isolated guinea pigs and a
negative frequency effect on the left atrium of isolated guinea pigs. In addition to the polarization induced by
norepinephrine, CaCl2 and high K+, the aorta contraction dose-response curve of rabbits was shifted to the
right and the maximum response was decreased, indicating the role of biosynthetic compound in relaxing
vascular smooth muscle. Fructus cnidium has a certain antihypertensive effect.
Effects on respiratory system
Cnidium monnieri total coumarin with relaxation by drugs (histamine and acetylcholine) caused by bronchial
spasms and diastole bronchus role directly, this function can be B - adrenaline receptor blockers block by propranolol,
mice after total coumarin cnidium monnieri, obviously increase the amount of phenol red drain in the body, shows
strong expectoranting action.
Anti-inflammatory effects
Cnidium cnidium and phenolic zanthoxylum could inhibit the ear shell swelling of mice caused by xylene
and the increase of capillary permeability in abdominal cavity caused by acetic acid. Osthol and acetonol had
significant inhibitory effects on foot swelling in rats and rats with bilateral adrenal resection. Osthol could also
reduce the PGE content in the inflammatory tissues of the swollen part of the foot in rats, but osthol did not
affect the PGE content in the inflammatory tissues of the swollen part of the foot in rats.
Effects on the nervous system
The total coumarin of cnidium cnidium has an inhibitory effect on central nervous system. Osthol can
significantly enhance the hypnotic effect of pentobarbital sodium on subthreshold hypnotic dose in mice, and
this hypnotic effect is dose-related. Cnidium cnidium can promote the learning and memory of mice, and
significantly improve the memory acquisition, consolidation and direction discrimination of mice.
Anti - mutagenesis, anti - cancer effect
Cnidium, parsley b, bergamot lactone, isorhein, zanthoxylum acetaminophen and zanthoxylum toxin
have high activity in inhibiting the mutagenesis of aflatoxin B1. Water extract of cnidium could inhibit S130
sarcoma, prolong survival days and inhibit tumor growth.
