The efficacy and function of senna leaves

Senna

In recent years, it has been mainly used at home and abroad for intestinal cleansing preparation before various abdominal and intestinal imaging examinations or before surgery. It is mainly used to treat various constipation, especially senile and stubborn constipation; it also promotes the recovery of intestinal function after abdominal surgery. It can also be used for upper gastrointestinal bleeding, cholecystitis, and acute pancreatitis. It is the most widely used cathartic agent in the world. But its adverse reactions are also increasing.

1. Pharmacological action

Step 1: Laxative effect.

Senna leaves contain anthrone derivatives, which have a stronger laxative effect and irritation than other laxatives containing anthraquinones, so diarrhea may be accompanied by abdominal pain. Its active ingredients are mainly sennoside A and B, which are absorbed by the stomach and small intestine and decomposed in the liver. The decomposition products circulate through the blood and excite the medullary disc ganglia to contract the large intestine, causing diarrhea. The effect of senna is wide and strong, and

It is considered more suitable for acute constipation than chronic constipation.

Step 2: Antibacterial.

Senna plants can produce many economically valuable compounds. In addition to the laxative effect, some senna leaves also have antibacterial, antibiotic and detoxification effects. The aqueous extract of senna leaves has an inhibitory effect on skin fungi such as Trichophyton audouinii and Nocardia stellate in test tubes.

The alcohol extract of Senna obovata has an antibacterial effect on a variety of bacteria (Staphylococcus, diphtheria, Salmonella typhi, Salmonella paratyphi, and Escherichia coli). Its water extract is only effective against Salmonella typhi. The seeds of Senna auricularia auricularia can lower fasting blood sugar in dogs, and the whole plant also contains cardiac glycosides.

Step 3: Hemostasis.

Effective for gastric and duodenal bleeding. Use the aqueous extract of this product to spray on the bleeding area of ​​the stomach under a gastroscope, and direct observation will show an immediate hemostatic effect. Intraperitoneal injection of 200 mg/kg senna glycosides can significantly shorten the bleeding time of mice. Oral administration of senna leaves can increase the platelet count and fibrinogen content, and shorten the coagulation time, thromboplastin time, plasma recalcification time, and clot contraction time. In addition, the protective effect of this product on gastric mucosal damage in rats induced by hydrochloric acid and indomethacin is also beneficial for the prevention and treatment of gastric and duodenal bleeding.

Step 4: Muscle relaxation.

It can block the transmission of impulses at the nerve-muscle junction and relax skeletal muscles. Senna can counteract the smooth muscle spasm caused by acetylcholine and gradually restore normal peristalsis of the intestine.

Step 5 is about cleaning the intestines.

Radiology departments like to use senna leaves to cleanse the intestines before abdominal plain films, colon and pyelography, and surgical abdominal operations, and patients also find it convenient. Even if the cleaning is not ideal, you can still perform a cleansing enema. After more than 80 years of practice, it has gradually been promoted.
