Great Green Tea: Half from West Lake, Half from Thousand Island Lake

 When people think of China’s finest green tea, they picture West Lake in Hangzhou—the villages of Longjing and Meijiawu, Emperor Qianlong’s legendary “Eighteen Imperial Tea Bushes,” and a cup of flat, jade-green leaves releasing delicate chestnut notes. And they’re not wrong. West Lake Longjing is indeed one of China’s most iconic teas. But few know that 150 kilometers southwest of Hangzhou, amid the emerald waters of Thousand Island Lake, lies another chapter of tea history—one far older, equally profound, and unjustly overlooked. Here, during the Tang Dynasty (618–907 CE), tribute tea known as Jiukeng Maojian was sent to the imperial court. Lu Yu, the Sage of Tea, recorded its origin in his Classic of Tea (Cha Jing). Centuries later, seeds from this very land would travel to Japan, Kenya, and beyond, shaping green tea across continents. Today, protected as a Class-I national water source, this region bans chemical pesticides entirely—yielding tea of unmatched purity and freshnes...

Tea and the Relationship with Cardiovascular Disease

  Cardiovascular disease is a leading cause of death worldwide, and tea is one of the most widely consumed beverages globally, as well as a primary source of caffeine for adults. The habit of drinking tea originated in China thousands of years ago, but since then, it has spread worldwide. Evidence from observational and  randomized controlled studies  suggests that  green tea  has many potential benefits in reducing the risk of cardiovascular disease, including reducing the risk of  major cardiovascular events , lowering blood pressure, lowering low-density lipoprotein cholesterol (LDL-C) levels, and aiding in weight loss. At the same time, the  physiological mechanisms  by which tea provides cardiovascular benefits are continually being investigated. Many studies have found that the main component of tea that provides cardiovascular protection is tea polyphenols, primarily catechins. Clinical evidence shows that drinking tea can reduce the risk o...
