"Mints", smells and traditional uses in Thessaloniki (Greece) and other Mediterranean countries 总被引:1,自引:0,他引:1
The herbs of the "mint" group traded in the herbal market of Thessaloniki include eight taxa, members of two genera, Acinos (two species) and Mentha (four species and two hybrids). The essential oil content of 72 samples examined ranged from traces up to 1.69ml/100g of dry weight. Besides three almost scentless samples, the different "mints" are distinguished according to their prominent smell differences, i.e. samples with a pungent, musty and sweet type of smell. As a result, the commercial names attributed to them correspond to a particular type of smell and not to a particular taxon. A number of 29 medicinal uses were recorded in total. In most cases uses were not associated with particular taxa but were rather determined by plant smells. A literature survey has shown that the "mints" traded in Thessaloniki are also used as herbal medicines all over the Mediterranean area, with 67 different therapeutic uses. Among them the 22 uses, already mentioned by Dioscurides, show that the utilization of "mints" as herbal medicines in the Mediterranean countries has a long tradition. 相似文献

Thirty three patients and nine volunteers were observed. 18 out of 33 patients felt PSC and Qi reaching to face induced by needle points. The QiRA rate was 80% in patients with face diseases. During acupuncture "Hegu" (LI 4) points, most of the patients felt PSC reaching to their faces and sensed heat in face. The infrared thermal image demonstrated that the temperature of face skin increase and the hyperthermal areas coincided basically with the pathway of "Yangming" channels. Those effects were more than the effects of the other objects who didn't feel PSC or sensed Qi reaching to face induced by needle "Hegu" (LI 4) or "Daling" (P 7) Points. The difference between the two groups was statistical significant. The temperature rising responses induced by needle points were not the results of natural fluctuation. The above results indicate that the PSC and QiRA is objective existence. 相似文献

借超分子“印迹模板”的自主作用解开金(山)银花纷争 总被引:2,自引:0,他引:2
自2005年版《中国药典》将金(山)银花分列后,纷争便不断上演,且愈演愈烈。尽管《中国药典》将"双花"分列,却没有给出两者在中药药性、功效主治、用法用量的差异以及具体解决办法,难以使中药行业人员信服。众所周知,在漫长的中药入药史上,一药多种,一种多药的现象俯首可拾;到底能合能分应该由临床等效情况确定。透过2015年版《中国药典》,仍可看出金(山)银花之纷争仍未找到科学的解决办法,这可能欠缺对中医临床治病的"异病同治"、"同病异治"与"同证多方"、"一方多证"的用药规律全面分析;更没有深邃分析中药多成分与经络脏腑作用超分子"印迹模板"自主作用规律;也没有关注中药复方多成分的有效性与安全性评价技术的进步;仍然受到了"一药一构一效"唯成分论用药模式影响;再加上中药临床前与临床中的生物等效性研究方法贫匮,终使问题得不到解决。金(山)银花分合列之争表象是地域经济、药物有效性与安全性的生物等效性之争,实际上却是中医药学科临床辨证施治治病的原理之争;更确切地说是中西医治病用药的药物观念之争。该文将梳理金(山)银花研究现状,结合中医临床治病的整体辨证施治与遣药组方治病的"异病同治"、"同病异治"与"同证多方"、"一方多证"的规律;运用超分子"印迹模板"自主作用规律阐明金(山)银花的"异质等效"的中药药理特有规律;并提出金(山)银花生物等效性的研究方法,为解决金(山)花的分合问题,促进中药材产业的发展奠定基础。 相似文献

传统中医常“泄泻”并称,指泄泻病证,但在中医典籍中“泄”“泻”两字基本是独立使用,各有所指。“泄”除了主要表示便泄外,另有五义,其基本义是排出,如“炅则气泄”,另还指“以苦泄之”的药食法和“满者泄之”的针刺法等。而“泻”字则有四义,除了一义与“泄”相近指腹泻病证外,主要用于“实则泻之”的补泻法,此外还指“藏而不泻”的输泻功能和泽泻药名。泄、泻两字音同义异,中医典籍译家以及中医术语标准中或有用一词翻译多义的,或有将两字混为一译的,对于这两种一概而译和交叉混译的倾向须进一步辨明两字差异,以求在译文中体现其中医内涵。 相似文献

Objective
To explore the clinical effects of electroacupuncture (EA) at Zusanli (ST 36) and Fenglong (ST 40) in treating senile dementia.Methods
A total of 74 patients were randomly divided into an EA group and a medication group based upon the random digital table, 37 cases in each group. EA at Zusanli (ST 36) and Fenglong (ST 40) was given in the EA group, once every day, for six treatments per week. Donepezil Hydrochloride Tablets were given to the medication group, 5 mg per time and once a day in the former four weeks, 10 mg per time and once a day after 4 weeks, oral administration before sleep at night. The courses of the treatment were 12 weeks in both groups. The scores of mini-mental state examination (MMSE) and Barthel index (BI) were observed before and after the treatment, for processing the comparative analysis of the clinical effects after the course of the treatment.Results
The total effective rate was 86.5% in the EA group and 70.3% in the medication group. The therapeutic effect was better in the EA group than that in the medication group, and the difference between the two groups was statistically significant (P<0.05). MMSE and BI scores after the treatment in the two groups were all elevated than those of the same groups before the treatment (P<0.05, P<0.01). The improving situation was obviously better in the EA group than that in the medication group, and the difference between the two groups was statistically significant (P<0.05).Conclusion
EA at Zusanli (ST 36) and Fenglong (ST 40) is affirmative in the therapeutic effect for senile dementia and can also improve the cognitive function and enhance the patients’ quality of life.18.
The hepatotoxic-protective effects of "San-fang-feng" (the root of E. grijisii) and "Lou-lu" (the root of E. latifolius) on CCl4 induced hepatotoxicity have been proposed in our previous paper (Lin et al, 1990). The anti-inflammatory effects of these two crude drugs were investigated in this experiment. The results indicated that both of them displayed pronounced anti-inflammatory activities against carrageenan-induced edema. Furthermore, in order to isolated the main active components of E. grijisii, fractions obtained from the methanolic extract of E. grijisii were investigated in mice for their 24-h LD50 and 95% confidence limits, which could be used as a guiding for further animal experiments. Our findings demonstrated that n-hexane (100,300 mg/kg), chloroform (30,100, 300 mg/kg) and ethyl acetate (30,100, 300 mg/kg) fractions could markedly inhibit the carrageenan-induced inflammation, and the main active principle was found to be concentrated in the chloroform fraction, which possessed significant inhibitory activities even more than does indomethacin. 相似文献
