Rehmannia root or Chinese foxglove root
Ingredient Name: Rehmannia root, Chinese foxglove root, Sheng di huang, Radix Rehmanniae
Chinese Name: 生地 (Shēng dì)
A very interesting and scary looking Chinese medicine. My herbalist recommended this to me for my “cooling” tea to rid me of my “fiery” condition of sore throat and heaty body. I had to ask him a few times what it is and then spell it for me in the simplest of Chinese terms, but I managed to come to a good understanding of this ingredient. This will make any water, soup, tea, drink BLACK – so beware. It’s not a bad thing, but sometimes black and dark things aren’t the most pleasant things to drink – well, except for black coffee for some people and cola. But in Chinese medicine, black is usually associated with bitter.
