千百年来,人们长期使用一种长得酷似仙人掌的植物——芦荟来治疗疾病,因为它具有可以愈合伤口的神奇功效。但是至今仍没有人能够完全解释,这种北非土产的植物是如何发挥神奇功效的,因此芦荟——百合科的一种多汁植物,一直得不到科学界的认可。现在,科学家们在观察中得知,从肥厚的芦荟叶中获得的液体,可以用来治疗伤口,而且只要稍稍抹上一点就够了。每个从事芦荟研究的科学家,对芦荟为何能够疗伤这一问题,仍持有各自不同的看法。有人认为,叶子中的凝胶可以减轻炎症,因此能促进伤口愈合。而有的人却说,这是因为这种植物中含有丰富的维生素和矿物质。此外还有人认为,芦荟所起的是湿润伤口的作用,因为伤口的愈合需要在一个相对潮湿的环境中进行。
For thousands of years, people have long used a plant that looks like a cactus, aloe vera, to treat diseases because it has the magical effect of healing wounds. However, no one has yet fully explained how this indigenous plant in North Africa can exert its magical effects. Therefore, aloe, a succulent plant of the family Liliaceae, has never been recognized by the scientific community. Now, scientists have learned from observation that liquids obtained from the leaves of hypertrophic aloe can be used to treat wounds, and it is sufficient to apply only a little. Every scientist engaged in the study of aloe vera still holds different views on why Aloe Vera can heal this problem. Some people think that the gel in the leaves can reduce inflammation and therefore can promote wound healing. Some people say that this is because this plant is rich in vitamins and minerals. In addition, some people think that the effect of aloe vera is to moisten the wound, because the healing of the wound needs to be performed in a relatively humid environment.
