Green tea is a commonly consumed beverage in the world and it is a rich source of polyphenolic compounds, which are known as the tea flavonoids. Polyphenolic compounds are effective against oxidative damage in various pathological conditions. Many herbal medicines are used in traditional medicine for their protective and therapeutic properties against various diseases. Among their bioactive components, tea catechins have been found to be active against all kind of diseases including cancer. Extensive report is available that green tea displays a wide range of healthy properties, such as antioxidative, anti-inflammatory, anti-apoptotic and chemopreventors against reactive oxygen and nitrogen species. This review aims to critically analyze the available literature regarding the effects of green tea or tea catechins with special emphasis on its phytoremediation against various health disorders elicited by different chemical compounds. Overall, data in literature show tea catechins appear to be a promising elixir to recover the illness of human beings.

Fluoride (F) is released into the environment through a combination of natural and anthropogenic processes include the weathering from volcanoes, geothermal activity, and marine aerosols. Chronic fluoride exposure has been linked with amyriad of human diseases such as skeletal and dental fluorosis, diabetes, atherosclerosis, cardiovascular diseases, and hyperkeratosis. Since fluoride targets ubiquitous enzyme reactions, it affects nearly all organ systems in animals and humans. Apart from synthetic chemical chelators, studies have been carried out to explore natural antioxidants against F toxicity. Natural products contain substances that inhibit the theoxidation of substrate(s). Antioxidant molecules are thought to play a crucial role in counteracting free-radical-induced damage to macromolecules. In this book chapter literature survey of the different phytoremediation strategy is presented. The results show that natural antioxidants exhibit promising antidote against fluoride-induced toxicity in different mammal systems.
