Does Tea Increase Immunity?

Tea is a beverage prepared by boiling the leaves of the Camellia sinensis bush. The health benefits of tea have become a prominent subject of research in recent times. Several varieties of tea such as Darjeeling tea, Sencha, Assam Black tea have been studied extensively in clinical research for their effect of human health.

Owing to the bitter-sweet flavours of tea and the effect of tea on mental alertness, places where tea is widely consumed not only include China, Japan, Germany, India, but all over the World. The chemical composition of tea, especially Darjeeling tea, consists of many antioxidant polyphenols, as well as L-theanine and theophylline.

According to citation, Antioxidant polyphenols could promote immunity by forming receptors that allow the binding of free radicals and initiate immune response.  L-theanine and theophylline in tea have been studied to promote alertness and increase efficiency, while also keeping one calmer than having consumed coffee. 

Compared to black tea, green tea and white tea are even less processed and filled with antioxidant polyphenols, making them an even healthier alternative to the normal black tea, or black tea with milk and sugar.

Recently, flavoured teas and herbal tisanes, such as chamomile tea, turmeric tea, and lavender tea have gained prominence because of their scented aromas and additional health benefits such as anti-inflammatory properties of turmeric, and relaxing effects of chamomile tea and lavender tea.
