“…Zhao et al [45], for example, found significant toxicity in Cytophaga columnaris fish species. Goel et al [46] studied the hepatotoxic effects of TA in two teleost fish, Varanka et al [47] assessed the toxic effects in Cyprinus carpio fish, and Xie et al [48] examined the same effects in zebrafish and Saha et al [49] in Oreochromis mossambicus fish, as well as chronic effects after 90 days' exposure. Although limited, some literature is available about the toxicity of TA in soil biomarkers, for example, on legumes [50].…”

Tannic acid (TA) is a key tannin extensively used in the leather industry, contributing to around 90% of global leather production. This practice leads to the generation of highly polluting effluents, causing environmental harm to aquatic ecosystems. Additionally, tannins like TA degrade slowly under natural conditions. Despite efforts to reduce pollutant effluents, limited attention has been devoted to the direct environmental impact of tannins. Moreover, TA has garnered increased attention mainly due to its applications as an antibacterial agent and anti-carcinogenic compound. However, our understanding of its ecotoxicological effects remains incomplete. This study addresses this knowledge gap by assessing the ecotoxicity of TA on non-target indicator organisms in both water (Vibrio fischeri, Daphnia magna) and soil environments (Eisenia foetida, Allium cepa), as well as natural fluvial and edaphic communities, including periphyton. Our findings offer valuable insights into TA’s ecotoxicological impact across various trophic levels, underscoring the need for more comprehensive investigations in complex ecosystems. Our results demonstrate that TA exhibits ecotoxicity towards specific non-target aquatic organisms, particularly V. fischeri and D. magna, and phytotoxicity on A. cepa. The severity of these effects varies, with V. fischeri being the most sensitive, followed by D. magna and A. cepa. However, the soil-dwelling invertebrate E. foetida shows resistance to the tested TA concentrations. Furthermore, our research reveals that substantial TA concentrations are required to reduce the growth of river microbial communities. Metabolic changes, particularly in amino acid and amine metabolism, are observed at lower concentrations. Notably, the photosynthetic yield of river periphyton remains unaffected, even at higher concentrations. In contrast, soil microbial communities exhibit greater sensitivity, with significant alterations in population growth and metabolic profiles at a very low concentration of 0.2 mg/L for all metabolites. In summary, this study offers valuable insights into the ecotoxicological effects of TA on both aquatic and terrestrial environments. It underscores the importance of considering a variety of non-target organisms and complex communities when assessing the environmental implications of this compound.

By reviewing the literature on the efficacy of tannins in traditional Chinese medicine in the last decade or so, we have classified the anti-tumor mechanism of tannins in conjunction with the latest mechanism exploration in the field of oncology. Tannins, a class of multi-phenolic compounds widely present in the diet, have been studied by scholars worldwide in recent years because of their relatively outstanding pharmacological activities. The mechanisms of anti-tumor action of tannins can be summarized as follows: the arrest of the cell cycle, arrest of tumor migration, enhancement of immune competence, induction of apoptosis, and antioxidant effects.
