Du Huo (独活): What Is It, Benefits, Uses, and Risks

Du huo(独活), also known as Doubleteeth Angelicae Root or Angelicae Pubescentis Radix, is a traditional Chinese herb with a long history of use in medicine. Let’s dive into the world of this fascinating plant and explore its potential benefits, uses, and risks.

What is Du Huo?

Du huo is the dried root of Angelica pubescens Maxim. f. biserrata Shan et Yuan, a perennial herb belonging to the Umbelliferae family. It’s primarily cultivated in the Chinese provinces of Sichuan, Hubei, and Anhui¹.

Fun fact: In ancient times, du huo and qiang huo (another Chinese herb) were often confused. It wasn’t until the famous herbalist Tao Hongjing pointed out their differences that people started using them separately.

According to traditional Chinese medicine (TCM), It has the following properties²:

• Taste: Pungent and bitter
• Nature: Slightly warm
• Meridians: Liver and Bladder

These properties give du huo its unique effects on the body. But what exactly can it do for us?
