Pharmacological effects Experiments on the effects of the digestive system showed that: Galangal decoction gavage the dog can make gastric acid excretion significantly higher than the control group, but no significant effect on gastric protein activity. Giving the mice gavage can significantly inhibit the gastrointestinal propulsive rate of ink against atropine, and can counteract the diarrhea caused by senna, but it can not counteract the purgative effect of castor oil. Senna to stimulate colonic laxatives, and castor oil to stimulate intestinal laxatives, most of the warm drugs to stimulate colon diarrhea have antidiarrheal effect. Reports indicate that Gaoliangjiang decoction has excitatory effects on ex vivo rabbit intestine movements, small doses can fight hexahydrocarbachlor and atropine, and higher doses can combat adrenergic and propranolol inhibiting jejunal activity in isolated rabbits. Lamin can't fight it. It is suggested that the excitatory activity of Galangal may not be related to cholinergic nerves and M-receptors but may be related to histamine-like and anti-adrenergic effects. Antibacterial effect in vitro, Galangal has inhibitory effects on human Mycobacterium tuberculosis. In vitro experiments showed that: Galangal decoction (100%) is against Bacillus anthracis, alpha-hemolytic streptococcus, beta-hemolytic streptococcus, diphtheria, diphtheria pharyngid, pneumococci, staphylococcus aureus, staphylococcus saturensis Staphylococcus aureus, Bacillus subtilis, etc. have different degrees of antibacterial effect. Other effects Galangal water extract or volatile oil to gavage rats, have anti-thrombotic effect; can make part of kaolin clay plasminogenase time significantly longer, but the plasma prothrombin time, prothrombin time, thrombin time , V factor, VII factor, etc. have no significant effect, indicating that they participate in the endogenous coagulation system and have a certain anticoagulant effect. Water extract can significantly inhibit ADP or collagen-induced platelet aggregation in rabbits. Gaoliang ginger decoction can significantly delay the time of the hyperalgesia (hot plate) reaction in mice. Its analgesic effect may be related to its inhibition of prostaglandin synthase and phosphatase. Galangin extract and water extract can significantly prolong the duration of opening mouth mice and the survival time of potassium cyanide poisoning mice, but have no effect on the survival time of sodium nitrite poisoning mice. The ether extract can prolong the survival time of oxygen-deficient mice in normobaric confined and slow the oxygen consumption rate of the organism; the water extract has no prolonging effect on the survival time of the mice under normobaric confined hypoxia, but can increase the mice's hypoxic conditions. Under the use of oxygen. FFP2 5 Ply Disposable Face Mask
