ADVERTISMENT  By Rachel Baxter 14 OCT 2019, 16:30 Tea has likely been around for thousands of years, thought to have first been drunk by the Shen Nong Dynasty of China as a medicinal drink. Over time, it spread around Asia and across the world, with the Brits first getting their hands on a cuppa in the 17th century. Tea is purported to have all sorts of health benefits, from weight loss to improving mental wellbeing, although much of the evidence is weak. Now, a small study published in Aging suggests that a nice hot brew might have a beneficial effect on the structure of our brains.
