Tea is one of the most widely consumed non-alcoholic beverages in the world next to water. It is classified as Camellia sinensis and non-Camellia sinensis (herbal teas). The common bioactive compounds found mainly in green teas are flavan-3-ols (catechins) (also called flavanols), proanthocyanidins (tannins) and flavonols. Black tea contains theaflavins and thearubigins and white tea contains l-theanine and gamma-aminobutyric acid (GABA), while herbal teas contain diverse polyphenols. Phytochemicals in tea exhibit antimicrobial, anti-diabetic and anti-cancer activities that are perceived to be helpful in managing chronic diseases linked to lifestyle. Many of these phytochemicals are reported to be biologically active when combined. Knowledge of the synergistic interactions of tea with other teas or herbs in terms of biological activities will be of benefit for therapeutic enhancement. There is evidence that various types of teas act synergistically in exhibiting health benefits to humans, improving consumer acceptance and economic value. Similar observations have been made when teas and herbs or medicinal drugs were combined. The aim of this review is to highlight potential beneficial synergies between combinations of different types of teas, tea and herbs, and tea and medicinal drugs. © 2017 Society of Chemical Industry.
茶是世界上除水之外消费最为广泛的非酒精饮料之一。它分为茶树茶和非茶树茶（花草茶）。主要在绿茶中发现的常见生物活性化合物有黄烷-3-醇（儿茶素）（也称为黄烷醇）、原花青素（单宁）和黄酮醇。红茶含有茶黄素和茶红素，白茶含有L-茶氨酸和γ-氨基丁酸（GABA），而花草茶含有多种多酚。茶中的植物化学物质具有抗菌、抗糖尿病和抗癌活性，被认为有助于管理与生活方式相关的慢性病。据报道，这些植物化学物质中的许多在组合时具有生物活性。了解茶与其他茶或草药在生物活性方面的协同相互作用将有助于提高治疗效果。有证据表明，各类茶在对人类展现健康益处、提高消费者接受度和经济价值方面具有协同作用。当茶与草药或药物组合时也有类似的发现。本综述的目的是强调不同类型的茶、茶与草药以及茶与药物组合之间潜在的有益协同作用。© 2017化学工业协会。
