9. Pharmacological research
The decoction and its contained matrine can produce diuretic effects when administered orally or injected into rabbits; The decoction has an inhibitory effect on Mycobacterium tuberculosis at high concentrations in test tubes; Decoction and water infusion have inhibitory effects on certain common skin fungi in vitro; Alcohol extract has anti trichomonas effect in vitro; Matrine was injected into rabbits and central nervous system paralysis was observed, accompanied by spasms, ultimately leading to respiratory arrest and death. Injected into frogs, initially excited, then paralyzed, breathing becomes slow and irregular, and finally spasms occur, resulting in respiratory arrest and death. The onset of spasms may be due to overactive spinal reflexes. The minimum lethal dose for domestic rabbits is 0.4 grams per kilogram. There is a positive inotropic effect, and excessive dosage can cause spontaneous contraction and decreased excitability of the heart; Antiarrhythmic; Anti myocardial ischemia; Expand blood vessels and increase perfusion volume; Can counteract the central excitatory effect of caffeine; Can relieve asthma and prevent allergies; Inhibiting the immune system; Elevated white blood cells; Anti tumor, anti-inflammatory, anti pathogenic microorganisms, enhancing the propulsion function of mouse small intestine, protecting gastric mucosal damage, etc. Toxic.
