Tannins are natural phenolic compounds that are widespread and almost ubiquitous in the vegetal world. They can be found in fruit, wood and bark of trees, and many types of wild herbs and plants or from sustainable agriculture and forestry. Their traditional use for leather has been doubled for centuries in the popular medical and pharmacological lore by their use to cure or alleviate a variety of infections and diseases. This has indicated to modern researchers that these materials possess a great potential for the use in modern medicine and pharmacy. This review, after an introduction on tannins their structures and their basic chemistry describe what modern researchers have been able to glean and demonstrate of their real, identified and quantified effects on various diseases, from their bactericidal, anticancer and antinflammatory actions to the many other effects that putsnow in more close focus in pharmacology.

单宁是一种天然酚类化合物，在植物界广泛存在且几乎无处不在。它们可以在水果、木材和树皮以及多种野生药草和植物中找到，也可以从可持续农业和林业中找到。几个世纪以来，在流行的医学和药理学知识中，它们用于皮革的传统用途已经翻了一番，因为它们用于治疗或缓解各种感染和疾病。这向现代研究人员表明，这些材料在现代医学和药学中具有巨大的应用潜力。这篇综述在介绍了单宁的结构和基本化学后，描述了现代研究人员能够收集和证明它们对各种疾病的真实、确定和量化的影响，包括杀菌、
