What is Prepared Rehmannia Root?

Prepared rehmannia root, also known as Shu Di Huang in Chinese, is a traditional Chinese medicine ingredient that is derived from the root of the rehmannia plant. This plant is native to China and has been used for medicinal purposes for over 2,000 years.

Prepared rehmannia root is commonly used in TCM to nourish the blood, improve energy levels, and support overall health. It is also used to help treat conditions such as anemia, fatigue, and hair loss.

How Can Prepared Rehmannia Root Help Treat Hair Loss?

TCM believes that hair loss is often caused by a deficiency in blood and Qi (energy), which can be caused by stress, poor diet, or other health conditions. Prepared rehmannia root is believed to help nourish the blood and Qi, which can improve the health of the hair and promote hair growth.

One study published in the Journal of Traditional Chinese Medicine found that a combination of prepared rehmannia root and other TCM ingredients, such as polygonum multiflorum and angelica sinensis, improved hair growth in individuals with hair loss.

Another study published in the Journal of Ethnopharmacology found that a topical preparation of prepared rehmannia root, when applied to the scalp, increased the number of hair follicles and the thickness of the hair in individuals with alopecia.

Prepared Rehmannia Root can be taken as a supplement or used as a topical treatment. It is also commonly combined with other TCM ingredients to create a more potent formula for treating hair loss.

Precautions and Side-effects

Prepared rehmannia root is generally considered safe when taken as directed. However, it is not recommended for women who are pregnant or breastfeeding. It is also not recommended for those who are taking blood-thinning medications or have a bleeding disorder, as it may increase the risk of bleeding.

It is always important to speak with a qualified healthcare professional before taking any new supplement or starting a new treatment, particularly if you have any underlying health conditions or are taking any medications.


Prepared rehmannia root is a traditional Chinese medicine ingredient that has been used for centuries to treat hair loss and promote hair growth. Studies have suggested that it may be effective in nourishing the blood and Qi, which can improve the health of the hair and promote hair growth.

It is important to note that more research is needed to fully understand the potential benefits of prepared rehmannia root for hair loss treatment. And as always, it is best to consult with a qualified healthcare professional before starting any new treatment.
