Galangal, also known as wind ginger, small galangal, galangal ginger, galangal, etc., is the dried rhizome of the ginger family. It is excavated in late summer and early autumn, and the fibrous roots and residual scales are removed, washed, cut into sections, and sun-dried. It can be used as medicine, and can also be used as a flavoring agent and in cooking.
Pharmacological effects of galangal powder
(1) Effects on the digestive system
Regulate gastric function
Its water decoction can strongly inhibit gastrointestinal propulsion, but can also promote gastric emptying. The 1:1 mixture of Galangal and Evodia has anti-stress ulcer in rats, inhibits gastric motility, reduces gastric tension, reduces contraction amplitude, and inhibits gastric acid secretion.
Regulate bowel function
Its water decoction has the effect of stimulating the intestinal tract, and can resist the intestinal activity caused by atropine and adrenaline, and its role is to stimulate the intestinal tract through histamine-like and anti-adrenaline-like effects. Galangal also contains substances that inhibit intestinal contraction caused by histamine, which can significantly inhibit the intestinal tension and contraction amplitude of rabbits, showing a similar effect to atropine.
Anti-stomach ulcer
Its water extract can obviously resist water immersion stress ulcer and prevent acute gastric mucosal damage caused by necrotic substances.
Promote gastric secretion
The leachate gavage can stimulate the increase of gastric acid excretion. Within 3 hours after perfusion, the total acid excretion was 3 times that of the control group. At the same time, the animals vomited and the gastric mucus increased.
Anti-diarrhea
Its water extract has obvious antagonistic effect on diarrhea caused by castor oil and senna.
Gallbladder
Its water extract has obvious choleretic effect when administered in duodenum.
(2) Influence on the circulatory system
Promote microcirculation
Rapid pain relief for angina pectoris. It can significantly delay the microvascular contraction time caused by epinephrine in mice, and the expansion of blood vessel diameter is significantly earlier than that of Chuanxiong.
Anticoagulant, antithrombotic, antipolymerization
Its water extract has anticoagulant effect, can delay the formation of experimental thrombus, and has obvious inhibitory effect on rabbit platelet aggregation.
cardioprotection
Its water extract has a certain protective effect on platelet aggregation and myocardial injury caused by stress. Galangal can significantly reduce serum and intrahepatic triglyceride levels.
(3) Anti-inflammatory and analgesic
Anti-inflammatory
Its water extract can inhibit the swelling of the auricle, the swelling of the foot and the increase of the capillary permeability in mice.
Pain relief
Its water extract can inhibit the writhing response and prolong the response to thermal pain stimuli when administered to mice. Its anti-inflammatory and analgesic effects may be related to inhibiting the release of prostatic synthesis.
(4) Others
Improve hypoxia tolerance
Its water extract can prolong the survival time of KCN poisoned mice, improve the oxygen utilization ability of mice under hypoxic conditions, and slow down the consumption rate.
Antitumor
Its ethanol extract has obvious inhibitory effect on mouse S180. The seven compounds contained in piperonol and eugenol have anticancer effects. The contained 1-acetoxy piperonyl acetate and related compounds have killing effect on human tumor cells.
Antibacterial, antifungal
Its decoction has different degrees of antibacterial effect on 1 kinds of gram-positive bacteria. Three piperonol derivatives have strong inhibitory effect on fungi.
It can also treat diarrhea
The water extract of galangal can also promote the digestion and absorption of the digestive tract, and it is reasonable to resist the diarrhea caused by castor oil. In addition, it can also work on the diarrhea caused by senna leaf, and can cure diarrhea and abdominal pain caused by food poisoning or poor diet.
At the same time, adjusting the blood circulation system of galangal has the actual effect of relieving severe pain in the heart, and has a delayed effect on the termination or slowing of the micro-arteriovenous flow caused by the adrenal hormone caused by mild severe pain.
