Abstract
Herb teas, Arabian jasmine, Balsam pear, Barley grass, Guava, Hardy rubber tree, Japanese persimmon, Jobs tears, Oolong tea, Puerh tea and Wolofberry have been consumed as beverages for health in Asia. Oxidative stress induces various diseases. Some of them, Arabian jasmine, Guava, Hardy rubber tree, Japanese per-simmon, Oolong tea and Puerh tea, have high total polyphenol content and antioxidant activities. Herbs and herbal polyphenols pay in controlling oxidation and prevent the damage by oxidation. These results showed that some of them, Arabian jasmine, Guava, Hardy rubber tree, Japanese persimmon, Oolong tea and Puerh tea, have high total polyphenol content and antioxidant activities. It has been demonstrated that high total polyphenol content in the herb teas provides high antioxidant activities.

Summary
Reactive oxygen species and free radicals induce oxidative stress. Oxidative stress is related to acute lung injury, acute respiratory distress syndrome and hyperoxia, aging, cardiovascular diseases as hypertension and myocardial infarction, cancer, diabetes, eye disease as age-related macular degeneration, immune diseases as inflammation and autoimmune disease, kidney disease, liver disease, neurological diseases as Alzheimer’s disease, Hungtington’s disease and Parkinson’s disease, and pancreatitis [1,2,3].The antioxidant pays in controlling oxidation and prevents the oxidation induced damage. Herbs have been consumed for food and medicinal purposes They have a wide variety of active phytochemicals, including allicin, anthocyanin, biochanin A, carotenoids, coumarins, curcumins, ellagic acid, epigallocatechin-3-O-gallate, flavonoids, lignans, phthalides, phytic acid, plant sterols, polyphenols, saponins, sulfides and terpenoids. They contain potent antioxidant compounds, prevent odidative stress and provide significant protection against chronic diseases [5,6]
