Pheasant and root
Pheasant and root
(Chinese Herbal Medicine News)
[source] it is the root and rhizome of Potentilla raspberry. See "chiziyan" for plant morphology.
[collection] it can be collected all year round, washed and dried in the sun.
[chemical constituents] it contains d-catechin.
[pharmacological action] d-catechin has vitamin P-like effect. It can reduce the permeability and fragility of capillaries, and enhance their resistance to trauma; that is, it has a certain role in maintaining the function of normal capillaries. In guinea pigs, d-catechin (1 mg / 300 g body weight by intraperitoneal injection or 5 mg / 800 g body weight by oral administration) has stronger capillary enhancing effect than flavonoids such as rutin, and has two peaks, which may not only delay the oxidation of epinephrine in vivo, but also have vitamin C-like effect. In vitro, d-catechin has stronger inhibitory effect on histidine decarboxylase than flavonoids, so it may have anti anaphylactic shock effect. In addition, it seems to have some excitatory effects on isolated guinea pig uterus. The toxicity to mice is very small (intravenous injection 1-1.5 g / kg, no toxic reaction). The median lethal dose of the alcohol extract from the root of pheasant was 4.2 g / kg.
