[clinical application] ① treatment of chronic tracheitis

Folium loquat preparation has obvious antitussive and expectorant effects, and has certain antiasthmatic effect; there are two effective parts, namely volatile oil and ethanol extract. The ketone compounds isolated from volatile oil have antiasthmatic effect, and the flavonoid compounds isolated from ethanol extract have expectorant effect. At present, volatile oil capsules, ethanol extracts, volatile oil emulsions and sugar coated tablets are widely used. The results of clinical trial showed that the effect of volatile oil combined with ethanol extract was better. Usage and curative effect: yivolatile oil capsule, each capsule contains 0.1 ml of volatile oil, 3 times a day, 1-2 capsules each time, the course of treatment is 20 days. 107 cases were observed, 6 cases (5.6%) were controlled and 22 cases (20.6%) were markedly effective. Two times a day, 25 ml each time after meals, the daily amount is equivalent to 4 liang of crude drug, 10 days for a course of treatment. 104 cases were observed, 6 cases (5.8%) were controlled recently, 28 cases (26.9%) were markedly effective. 113 cases were treated with volatile oil capsule 3-6 times a day and ethanol extract 25-50 ml twice a day for 10 days. Results 13 cases (11.6%) were controlled and 35 cases (30.5%) were markedly effective. 132 cases were treated with sugar coated tablets, 2 tablets each time, 4 times a day for 20 days. The daily amount of ethanol extract is equivalent to 2 liang of crude drug and 0.3 ml of volatile oil. Results 19 cases (14.4%) were controlled and 24 cases (18.18%) were markedly effective. According to the impression of hundreds of cases of clinical trial, the curative effect of Xiaoye loquat preparation seems to have a certain relationship with disease type, disease condition and constitution. The patients with simple type, mild condition and strong constitution have better curative effect, while those with wheezing type, severe condition, weak constitution and emphysema have poorer curative effect. Most of the patients had no adverse reactions during the treatment, and some of them had side effects such as diarrhea, stomachache, burning sensation, nausea, dry mouth or dizziness after taking the medicine, which seemed to have no obvious effect on liver function. In addition, loquat can be made into aerosol and inhaled by aerosol, which also has effect.

② Treatment of coronary heart disease

Two pills each time, three times a day, 30 days as a course of treatment. 127 cases were observed, the effective rate of angina pectoris was 31.5%, the total effective rate was 77.1%; the effective rate of ECG was 12.8%, the total effective rate was 39.3%. Some cases after two courses of treatment, the curative effect has been improved. There was no significant change in blood lipid after treatment. Less side effects, more dizziness, disappeared in the course of treatment.
