The efficacy and function of Pheasant root

Pheasant root has a long history, and until now, pheasant root has more and more uses. I wonder if you friends know about its other effects. Let us introduce it in detail below, hoping to be helpful to you friends.

[Source] It is the root and rhizome of Potentilla tataricum, a plant of the Rosaceae family. It can be harvested throughout the year, washed and dried.

[Original morphology] The plant morphology is detailed in the entry for "Pheasant Banquet".

【Chemical composition】 Contains the main active ingredient 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 plays a certain role in maintaining the normal function of 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 a stronger effect on strengthening capillaries than flavonoids such as rutin, and has two peaks of action. It may not only delay the oxidation of adrenaline in the body, but also have a vitamin C-like effect. In test tubes, d-catechin has a stronger inhibitory effect on histidine decarboxylase than commonly used flavonoids, so it may have an anti-allergic shock effect. In addition, it seems to have some stimulant effect on the isolated guinea pig uterus. It has low toxicity to mice (no toxic reaction was observed after intravenous injection of 1-1.5 g/kg). The alcohol extract of Pheasant's nest (root) was orally administered to mice, with a median lethal dose of 4.2 g/kg.

【Functions and indications】Oral administration for hemostasis.

[Clinical application] Treatment of various bleeding: Use the alcohol extract of pheasant root to make tablets (1 gram of raw medicine/tablet), take 3 times a day, 2 to 4 tablets each time. According to more than 400 case reports, among which: 1. 353 cases of general gynecological bleeding (including 15 types of bleeding such as functional uterine bleeding, uterine fibroid bleeding, simple menorrhagia, menorrhagia due to chronic pelvic inflammatory disease, and postpartum lochia), the effective rate was 86.3% and the marked effective rate was 58.7%. ㈡ 120 cases of gynecological bleeding caused by family planning, with an effective rate of 82.5% and a significant effective rate of 65.8%. ㈢ 14 cases of pulmonary tuberculosis with hemoptysis were treated, 7 were effective and 4 were markedly effective. The above-mentioned effective means that the effect is slow after taking the medicine or the amount of bleeding is reduced by half; marked effect means that the amount of bleeding is reduced by more than half or stops within 1 to 3 days. No obvious side effects were found clinically. Some patients experienced poor appetite, abdominal distension, dizziness, etc., which disappeared after stopping the medication.
