What is it

Clematis armandii (chuan mu tong in Chinese) is a climbing plant whose dried stem is used in traditional Chinese medicine for urinary and lactation support. It replaced aristolochic-acid-containing Aristolochia species in many traditional formulas.

How it works

Clematis armandii contains saponins, flavonoids, and triterpene glycosides. Traditional uses target urinary heat, lactation, and joint discomfort. Modern pharmacological characterization is limited. Importantly, this species is generally considered free of aristolochic acid, which is present in true Aristolochia species (formerly called mu tong in some older Chinese medicine texts). However, species confusion in the supply chain remains a real risk and lab testing for aristolochic acid is advisable.

Dosage

Traditional decoction doses range from 3 to 6 g per day. There is no established research-based intake recommendation.

When and how to take it

Traditional decoctions are typically taken between meals. Follow product label guidance for modern extracts.
