寄生虫通常会造成伤害，但它们也有一些有益的方面，但仍有待发现。重要的是要认识到寄生虫的有害和有益的方面。人们发现它们对不愈合伤口、手术伤口、肥胖、葡萄糖代谢紊乱、神经修复、癌症治疗和生育能力具有积极作用。研究表明，蠕虫、原生动物和节肢动物能够通过利用寄生虫本身、其分子甚至卵来纠正、预防和治疗某些疾病。本文包括关于寄生虫有益方面的研究。然而，还需要进一步的研究来充分了解寄生虫刺激或影响免疫系统的机制以及如何将其用于治疗。

Parasites are commonly associated with harm, but they also have beneficial aspects that are still being discovered. It is important to acknowledge both the harmful and beneficial aspects of parasites. They have been found to have positive effects on non-healing wounds, surgical wounds, obesity, glucose metabolism disorders, nerve repair, cancer treatments, and fertility. Research has shown that helminths, protozoa, and arthropods have the ability to correct, prevent, and cure certain disorders through the use of the parasite itself, its molecules, or even its eggs. This article includes studies on the beneficial aspects of parasites. However, further research is needed to fully understand the mechanisms by which parasites stimulate or affect the immune system and how they can be used therapeutically.
