Camellia Sinensis (Cha) Use in Traditional Chinese Medicine, Part Two: TCM Herbal Cha Decoctions
By Brenton Harvey, LAc, CH and Hong Ji
Traditional Chinese medicine (TCM) herbal decoctions using cha date back to the San Guo dynasty (also known as the Shi Dai dynasty), which occurred between 25 AD and 220 AD.
The classic text Guang Ya was written by Zhang.
This book discusses tea picking, tea cakes (tea pressed into bricks), drinking tea, and using tea as a topical skin treatment. The use of cha with fresh ginger and green onions to cure drunkenness was referenced.
Traditionally, it was common and very practical to sun-dry the herbs, then grind them into a powder to be added to boiled water. This is referred to as a "draft" in TCM. Many of the early cha herbal formulas were prepared and taken in this manner.
