What are the effects and functions of Alpinia oxyphylla

Alpinia oxyphylla is a pure Chinese medicine. Many people may not have heard of it, but it is widely used in clinical practice. Alpinia oxyphylla has many medicinal effects, is relatively warming and tonic, and has a wide range of effects. You can learn more about it.

1. Warming and strengthening, warming the spleen and stopping diarrhea, strengthening the saliva, warming the kidney and consolidating the essence and reducing urine. It is mainly used to treat spleen and kidney deficiency and cold, abdominal pain and diarrhea; or kidney deficiency and cold, frequent urination, enuresis, spermatorrhea, leukorrhea; or chronic diarrhea caused by spleen and stomach deficiency and cold, and uncontrollable saliva outflow from the mouth

2. Alpinia oxyphylla contains volatile oil, alpinia oxyphylla ketone, vitamin B1, vitamin B2, vitamin C, vitamin E and various amino acids, fatty acids, etc. The decoction of Alpinia oxyphylla has the effects of strengthening the stomach, resisting diuresis and reducing saliva secretion.

3. The water extract and ethanol extract have the effect of inhibiting ileal contraction. In addition, its methanol extract can enhance the contractility of the left atrium, inhibit the contraction of the aorta caused by potassium chloride, and inhibit the activity of prostaglandin synthase.

4. Inhibitory effect on prostaglandin synthesis. Experiments show that the methanol extract of the fruit of the polysaccharide has the effect of inhibiting the activity of prostaglandin synthase. The concentration of polysaccharide ketone A that inhibits prostaglandin synthase by 50% is 0.51umol. Effects on the heart. The methanol extract of Alpinia oxyphylla has the activity of enhancing the contractility of the left atrium of guinea pigs, and its minimum effective dose is 10-6g/ml. The reporter believes that the cardiotonic effect of phenoxyethanol is partly due to its inhibition of the sodium-potassium pump in the myocardium.

5. It has been reported that the compound preparation of Alpinia oxyphylla kernel, "Alpinia oxyphylla syrup", can improve energy metabolism and promote the synthesis of CA substances and cAMP. Animal experiments have shown that this preparation can increase the levels of NE, DA, cAMP in the mouse brain and plasma cAMP, and has the function of increasing memory and enhancing immunity.
