Recently, I spotted a pack of rooibos tea on sale in one of the health food stores around me. It was then I remembered the post-graduation thesis topic of my friend.

Nowadays, rooibos tea is becoming popular in the Western countries as well due to its peculiar fruity taste and enormous medicinal properties. Let us move further to see the positive health effects of this splendid drink.
Antioxidant Activity of Rooibos Tea
In recent years, a lot of research has been focused on free radical chemistry. First, let us see what free radicals are and how they affect our health? In our day to day life, oxygen mediates several essential chemical reactions in the body. However, some amount of oxygen creates cell-damaging molecules called free radicals. Think of these free radicals as “toxic by-products” of oxygen-mediated reactions in the body. These free radicals attack healthy cells, leading to various diseases and accelerated aging. Antioxidants, on the other hand, are protective substances that tend to neutralize these toxins. Therefore, a proper balance between free radicals and antioxidants is required for normal health and aging 9)http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3249911/.
Rooibos tea contains a natural powerhouse of antioxidants called “polyphenols”. These polyphenols protect our body from the cell damage caused by free radicals and help us ward off deteriorating diseases like Parkinson’s disease and certain types of cancers 10)http://www.naturalnews.com/041982_rooibos_tea_health_benefits_herbal_medicine.html.
Research also claims that processing rooibos tea by methods of fermentation, sun drying, steam pasteurization, and sieving causes reduction in the total phenolic content of the product 11)http://pubs.acs.org/doi/abs/10.1021/jf000802d. Hence, it is advised to have organic unprocessed rooibos tea gives the optimum health results.

Anti-Diabetic Effects of Rooibos Tea
Aspalathin, a rare antioxidant found in rooibos tea, has an exclusive quality of balancing our blood glucose level, thus improving insulin resistance and boosting insulin secretion from the pancreas.

Another animal study in 2012 17)http://www.sciencedirect.com/science/article/pii/S0944711312003200?np=y showed that the aspalathin content of rooibos has glucose-lowering potential.
