What are the medicinal values ​​of hibiscus flowers

Hibiscus is a very beautiful flower. Many people have seen the beautiful appearance of hibiscus, but few people know that this flower has rich medical value. It has a good effect on the treatment of some diseases. It can also regulate people's physical condition and even enhance people's physique. However, people need to understand the value of hibiscus flowers before using them correctly. So what are the medicinal values ​​of hibiscus flowers?

[Pharmacological action] Hibiscus contains glycosides, which can lower blood pressure in anesthetized dogs. Intravenous injection of 40-80 mg/kg of this glycoside (not pure) can sharply lower blood pressure, which will rise slightly and then fall again, lasting for 1-2 hours. This antihypertensive effect is not affected by atropine and also reduces blood pressure in spinal cord dogs. It has a spasmotogenic effect on smooth muscles (small intestine of rats, rabbits, and guinea pigs, bronchi of rats, dogs, and rabbits, uterus of rabbits, etc.), which can be blocked by atropine. It can contract the frog's rectus abdominis muscle (0.2-1 mg/ml) and can be partially antagonized by tubocurarine (4×10-8). In small intestinal smooth muscle specimens, 0.1-0.3 mg/ml of glycosides can turn to relaxation after causing contraction, and antagonize spasms caused by 5-hydroxytryptamine, acetylcholine, histamine, and barium chloride. The latter has a direct inhibitory effect on smooth muscle and does not seem to be the same substance as the spasm-inducing effect of stimulating cholesterin receptors.
