人体主要是依靠自身的免疫性来抵抗外来的病原体,这种免疫性包括血液淋巴系统的免疫作用和肠道的免疫作用。

The human body mainly relies on its own immunity to resist foreign pathogens, which includes the immune function of blood and lymph system and the immune function of intestinal tract.

血液淋巴系统的免疫作用是通过免疫蛋白体的形成,从而识别入侵人体的病原,再由人体内的白血球和淋巴细胞去消灭这些病原。

The immune function of haemolymph system is to recognize the pathogens invading human body through the formation of immune protein bodies, and then eliminate these pathogens by white blood cells and lymphocytes in the human body.

对于茶叶的现代研究已经表明,多饮茶,可以提高人体内白血球和淋巴细胞的数量及活性。

Modern research on tea has shown that drinking more tea can increase the number and activity of white blood cells and lymphocytes in human body.

另外,研究还证明饮茶可以促进脾脏淋巴中的白细胞间素I的形成。白细胞间素I是一种可以增强人体免疫力的物质,因此它的增加可以相应的提高人体的免疫机能。

In addition, tea drinking can promote the formation of interleukin-I in spleen lymph. Interleukin I is a kind of substance that can enhance human immunity, so its increase can improve the immune function of human body correspondingly.

人体肠道的免疫性是维持肠道健康的根本原因,肠道的免疫力与其中的微生物有很大的关系。一个成年人的消化道中含有大约100兆数量的细菌,种类有100多种,一部分是有益细菌,另一部分则是有害细菌。

The immunity of human intestinal tract is the fundamental reason to maintain the health of intestinal tract. The immunity of intestinal tract is closely related to the microorganisms. An adult’s digestive tract contains about 100 trillion bacteria of more than 100 species, some of which are beneficial and others are harmful.

许多国内的研究都证明茶叶对肠道中的有害细菌具有杀灭的作用,比如霍乱弧菌、金色葡萄球菌、大肠杆菌、肠炎沙门氏菌等等。即使茶汤浓度一般,其中的有效成分也可以抑制有害细菌的生长和繁殖。

Many domestic studies have proved that tea can kill harmful bacteria in the intestine, such as Vibrio cholerae, Staphylococcus aureus, Escherichia coli, Salmonella enteritidis and so on. Even if the concentration of tea soup is general, the active ingredients can inhibit the growth and reproduction of harmful bacteria.

另一方面,肠道中有许多对人体有益的细菌,比如双歧杆菌就特别重要。双歧杆菌的数量会随着年龄的增长而减少。婴儿时期可以占到肠道菌总数的95%,进入青年期下降到15%,到了50岁以上就只有5%左右啦。

On the other hand, there are many beneficial bacteria in the gut, such as bifidobacteria, which are particularly important. The number of bifidobacteria decreases with age. It can account for 95% of the total intestinal bacteria in infancy, 15% in youth, and only 5% in over 50 years old.

有益细菌的减少,会对人体带来不利的影响。研究发现饮茶可以增加双歧杆菌的生长和繁殖。所以,饮茶一方面可以抑制甚至消灭有害细菌,另一方面又可以促进有益细菌的生长和繁殖,能够很好的改善肠道的微生物结构,提高肠道的免疫力,增强人体健康。

The reduction of beneficial bacteria will bring adverse effects on human body. It was found that drinking tea can increase the growth and reproduction of bifidobacteria. Therefore, on the one hand, tea drinking can inhibit or even eliminate harmful bacteria, on the other hand, it can promote the growth and reproduction of beneficial bacteria, which can improve the intestinal microbial structure, improve the intestinal immunity and enhance human health.

目前,茶叶治疗痢疾的功效已经在临床中得到证实。据报道,用绿茶的浓浸出液治疗痢疾的效果优于化学药物,而且持效性时间较长。

At present, the efficacy of tea in the treatment of dysentery has been confirmed in clinical practice. It is reported that the effect of the concentrated extract of green tea on dysentery is better than that of chemical drugs, and the duration of effect is longer.

在试验中,用绿茶治疗痢疾后第2~3天,赤痢菌就受到抑制,第5~10天,患者完全康复。半年后再重新检查,发现患者仍然呈阴性反应,证明持效性是比较长的。

In the experiment, after the treatment of dysentery with green tea, Shigella was inhibited 2-3 days, and the patient recovered completely from 5 to 10 days. Half a year later, re examination found that the patient still showed negative reaction, which proved that the effectiveness was relatively long.

茶叶之所以可以治疗痢疾,是因为其中的儿茶素化合物(尤其是EGC和EGCG)对病原细菌有明显的抑制作用。

The reason why tea can treat dysentery is that catechins (especially EGC and EGCG) have obvious inhibitory effect on pathogenic bacteria.

在前苏联遗留下来的医院中,至今仍然在使用浓的绿茶煎汁供肠道病患者服用,既有治疗效果,同时也有预防效果,可以在长达几个月的时间里抑制有害细菌的繁殖。

In the hospitals left over from the former Soviet Union, strong green tea decoction is still used for patients with intestinal diseases. It has both therapeutic and preventive effects, and can inhibit the proliferation of harmful bacteria for months.

所以,多喝茶,少生病,是因为茶叶中的有效成分可以增强人体的免疫力,有效抵抗外来病原的入侵。同时,茶叶中的各种成分对一些疾病也有较好的治疗和预防作用。

Therefore, drink more tea, less sick, because the effective ingredients in tea can enhance human immunity, effectively resist the invasion of foreign pathogens. At the same time, the various components in tea also have good therapeutic and preventive effects on some diseases.
