| Chinese Rhubarb |
| Rheum officinale, R. palmatum|
| (Da huang; Turkey rhubarb)
Esteemed for 5000 years as a safe purgative. Action is brisk, healthy and non-constipating. Has marked anti-tumour properties and is one of 4 ingredients in the Essiac® anti-cancer formula. The history of rhubarb has more than a fair share of intrigue and colourful characters. For centuries the true source and identity of medicinal rhubarb was concealed to protect traders supplying the European market. Even today in China the botanical identity of the crude drug sold in the herb markets is usually unclear.
