Joint and musculoskeletal complaints (traditional use)

Mixed Evidence

Long traditional use in Chinese medicine for joint complaints. Direct controlled human evidence is limited.

How it works

Clematis species contain saponins (clematosides), triterpenes, and ranunculoside (a glycoside that liberates protoanemonin, an irritant). Animal and laboratory studies show anti-inflammatory effects on joint tissues. Fresh or improperly processed plant material contains protoanemonin, which is irritating to skin and mucous membranes. Properly dried and prepared material has reduced toxicity.

Dosage

Traditional decoction doses are 6-12 g of dried stem per day. Standardized extracts vary; follow product label.

When and how to take it

Traditional decoctions are taken between meals two to three times daily. Follow practitioner guidance.
