Key TCM concepts behind clematis roots (Wei Ling Xian)'s properties

In Traditional Chinese Medicine (TCM), clematis roots are plants that belong to the 'Herbs that dispel Wind and Dampness' category. These herbs typically help treat what's called 'bi pain' (i.e. painful obstruction) in TCM. This roughly corresponds to arthritic and rheumatic conditions with pain, stiffness and numbness of the bones, joints and muscles.

Furthermore clematis roots are plants that are Warm in nature. This means that clematis roots tend to help people who have too much "cold" in their body, although with less effect than a plant that would be Hot in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much cold in their body are said to either have a Yin excess (because Yin is Cold in nature) or a Yang deficiency (Yang is Hot in Nature). Depending on your condition clematis roots can help restore a harmonious balance between Yin and Yang.

Clematis roots also taste Pungent and Salty. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Pungent ingredients like clematis roots tend to promote the circulations of Qi and body fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food. On the other hand Salty ingredients tend to have a draining effect in the body because they clear accumulations, remove phlegm and soften hard lumps.

The tastes of ingredients in TCM also determine what organs and meridians they target. As such clematis roots are thought to target the Bladder. In TCM the impure water collected by the Kidneys that cannot be used by the body is sent to the Bladder for storage and excretion as urine.

Research on clematis roots (Wei Ling Xian)

Clematis chinensis Osbeck root is effective in ameliorating joint destruction and cartilage erosion in MIA‐induced osteoarthritic in rats, and the mechanisms of action for protecting articular cartilage are through preventing extracellular matrix degradation and chondrocyte injury.1
