Looking for it for two years, I can't find the document. The reason is that Notes on Materia Medica was written in 74 1 year, that is, in the 29th year of Tang Kaiyuan. The original book has long been lost.
But most of its contents can be seen from Zheng Ben Cao. In the various materia medica cited in Compendium of Materia Medica, the drugs contained in this book are also cited. When I got the book, I didn't see the effect of "tea" from the sweet clover. This makes me question the record that tea is a cure-all medicine. What made this sentence spread for so long?
Tea farmers who have raised tea trees for more than ten years know that unlike ordinary fruit trees, tea trees will die of old age without the direct influence of environmental changes such as human destruction and soil erosion. Although the trunk of some tea trees is dry, new branches and leaves will soon grow on the head of the tree after sawing off the dead branches. The growth period of tea trees is indeed much longer than that of humans.
More than 4,000 monographs on "tea anti-cancer" published by authoritative departments prove that EGCG, the main component of tea polyphenols, is the bane of almost all cancers. Researchers at Medical Pharmaceutical University found that 1300 diabetic patients drank cold boiled water tea. After half a year, the symptoms of 82% diabetic patients were obviously relieved, and the blood sugar level of about 9% diabetic patients completely returned to normal.
