What is Notopterygium incisum (Qiang Huo)?

Notopterygium incisum (qiang huo, 羌活), also known as Notopterygium Root, is the rhizome and root of Notopterygium incisum or Notopterygium franchetii, which is a perennial herb belonging to the family Umbelliferae. 

In spring and autumn, people will gather the roots and rhizomes of these plants, remove their fibrous roots and slit, dry them under the sun, and cut them into slices for medicinal usage. 

This herb first appeared in The Divine Farmer’s Materia Medica (Shen Nong Ben Cao Jing, 神农本草经) in the late Western Han Dynasty, where it was thought to be the same herb as Doubletooth Pubescent Angelica Root (Du Huo) till Tang Dynasty. Today, Qiang Huo is considered to be stronger in its properties and have a stronger flavour than Du Huo, making it the more suitable choice in the treatment of fevers, spinal diseases, and pain in the upper body and the back of the head. Comparatively, Du Huo has a stronger descending quality, making it better for the treatment of rheumatism in the lower body, and joint pain in the foot, lower back, legs and shin.

In Traditional Chinese Medicine (TCM), Qiang Huo falls under the category of ‘Warm/Acrid herbs that release the exterior’. Such herbs aim to treat the early stages of diseases that affect the upper respiratory tract, eyes, ears, nose, throat or skin. These herbs can induce sweating by increasing the flow of sweat to our capillary pores, which then expel external diseases from the body and prevent them from invading further.

Warm in nature, Qiang Huo can help individuals with too much Cold in their body, such as those experiencing a yin excess or a yang deficiency, to restore a harmonious yin-yang balance. Bitter and pungent in taste, Qiang Huo can cleanse the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. Also, Qiang Huo can promote the circulations of qi and body fluids. In particular, Qiang Huo targets the bladder and the Kidneys.

This herb is often indicated for cases with more severe syndromes of external Wind-Cold, manifested as symptoms such as aversion to cold, chills, fever, absence of sweat, headache, painful and stiff nape, body ache, and pain in the limbs. Qiang Huo is very effective in treating the above symptoms, especially when they are accompanied by Dampness with joint pain, a general feeling of heaviness, sleepiness and occipital pain.

Qiang Huo can also direct qi to the Tai Yang channel and Governing vessels, and hence can act as a guide herb for other herbs. The herb can also treat symptoms such as acid reflux caused by Qi Deficiency.
