锗是一种金属元素,与碳、硅同属一族,早在一百多年前人们已经发现了它的存在,并广泛地应用于电子工业。近年来,锗在治疗某些疾病方面,显示出了令人惊奇的效果。西欧某地曾发现一股山泉水使不少癌症患者的病情得到缓解,经化学分析发现,泉水中含有丰富的锗;日本学者也发现,一些抗癌效果较好的中药,其锗的含量也较高,如人参含锗高达250—320PPm,枸杞子124PPm,大蒜、灵芝等的含锗量也很高。过去一直认为,锗是一种有害的重金属,但在1987年11月在北京召开的自然医学会议上,日本、葡萄牙学者的研究报告指出:锗并非毒性物质,它具有多方面的生理功能,可治疗包括癌症在内的多种疾病。由于植物中含锗量不稳定,天然锗又不溶于水,所以在70年代中期日本学者成功地合成出可为人体吸收的有机锗化合物“二羧乙基锗三氧化物”。
Germanium is a metal element that belongs to the same family as carbon and silicon. It has been discovered for over 100 years ago and widely used in the electronics industry. In recent years, germanium has shown surprising results in the treatment of certain diseases. A mountain spring in western Europe has found a mountain of spring water to alleviate many cancer patients. The chemical analysis shows that the spring water contains abundant germanium. Japanese scholars also found that some traditional Chinese medicines with good anti-cancer effect have a germanium content Higher, such as ginseng containing germanium up to 250-320PPm, medlar 124PPm, garlic, Ganoderma lucidum and other germanium content is also high. Historically, germanium was believed to be a harmful heavy metal, but at the Natural Medicine Conference in Beijing in November 1987, a study by Japanese and Portuguese scholars found that germanium is not a toxic substance and that it has a wide range of physiological functions that may Treat a variety of diseases including cancer. Due to the unstable amount of germanium contained in the plants and the fact that natural germanium is insoluble in water, Japanese scholar succeeded in synthesizing the organic germanium compound “dicarboxyethylgermanium trioxide” which can be absorbed by human body in the mid 1970s.
