Rehmannia root or Chinese foxglove root

Submitted by on March 23, 2011 – 9:37 pm5 Comments | 17,844 views

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.

What is this?
  • The root of the Chinese foxglove plant
  • The root is harvested in the spring or autumn, dried in the sun and sliced into usable portions
  • This plant is most commonly found in China and the root is a common Chinese medicine ingredient
  • It is known as a “cooling” ingredient with sweet and bitter properties
  • The root is almost black in color and will certainly make your soup or tea black
  • Found in various forms such as dried (as picture above) or powdered

How do I prepare it?

  • Rinse in warm water before usage

Where can I buy this?

  • Most herbalists will carry this ingredient
  • Chinese medicine stores

What is the cost?

  • Relatively affordable
  • As pictured above, 2 pieces I purchase cost me $3 HKD

Any benefits?

  • Helps remove heatiness in the body and cool the blood
  • Relieves sore throats, dry mouths and helps cool the body to eliminate thick, green mucous caused by heatiness
  • Can help reduce a low-grade fever
  • Can help eliminate and reduce cold sores in the mouth and tongue
  • Nourishes the “yin”

Any precautions?

  • As it is cooling, it should be avoided by pregnant women in their first trimester (or even throughout a pregnancy) as it stimulates menstruation (it is also known to be used to prevent or terminate pregnancies)
  • Avoid if you’re lactating (breastfeeding)
  • Avoid using or consuming this ingredient if you have spleen problems, diarrhea or lack of appetite
  • Limit exposure and use for children

    Hi soup lady,

    I think I may be pregnant. I just drank half a bowl of soup with the chinese foxglove root in, and forgot that it is a ‘cool’ type of soup. Will this do a lot of harm?? Is there anything I can do to reverse it?! I am very worried!

    Thanks for your advice!

  • LadyTong says:

    Dear Debbie, no worries. There isn’t much you can do after drinking it as sometimes the hot doesn’t offset the cool, but there are many cases people drink/eat cool stuff when they didn’t realize they were pregnant either. Everyone’s body is different and this is just a general guideline, but I wouldn’t worry too much about it. Besides, half a bowl is mild with some foxglove root, I’ve had ginseng and chicken soup in my early days of pregnancies and watermelon! Just take it easy from here on forward and good luck! Lisa

    how do i prepare this? I just got the root and I dont know how to consume it?

  • LadyTong says:

    Dear Brittany, these are mainly used in herbal teas. See https://www.thechinesesouplady.com/heat-clearing-herbal-tea/. Hope this helps!

    This is the great info about Rehmannia. Because it is Chinese herbs it is difficult to find in the USA. I have found one Rehmannia Supplement hope it will work.
