[pharmacological action]

1: antibacterial and antiviral antibacterial effect widely, but the protein can be inactivated in the body. In vitro experiments showed that the antiviral activity of adenovirus and vaccinia, strong inhibition, followed by poliovirus type I and type III parainfluenza virus

2 anti venom: caffeic acid at a dose of 3 micrograms can completely inhibit 20 micrograms of rattlesnake venom phosphodiesterase, used as anti snake poison

3 other effects: oral or intraperitoneal injection, caffeic acid can improve the rat's central nervous system excitability; orally, can increase the secretion of hydrochloric acid in the stomach, and can make the pulse slow; can strengthen the uterine tension, this effect could be antagonized by atropine and papaverine, cannot affect the increase of rats; the secretion of bile. Elevated white blood cells, hemostasis and inactivation effect. Vitamin B1 can inhibit the formation of lipid peroxide in brain tissue homogenate. Shorten the bleeding time and blood coagulation function

4 toxicity: intraperitoneal injection of LD50 1583mg/kg; after intravenous injection 14mg/kg/ day for ten consecutive days, heart, liver, kidney function and anatomical examination showed no pathological changes

[use] antibacterial, antiviral, central excitement, detoxification, blood coagulation

[shelf life] 2 years

Store in a cool, dry place

[packing] 25 kg / cardboard barrels, lined with double plastic bags
