The ovate leaves are up to 7.3 cm (3 in) centimeters long and are usually coated with short hairs. Solitary flowers occur at the branch tips.

Uses

Traditional
Leaves
Dried Codonopsis pilosula root

The roots of C. pilosula are used in traditional Chinese medicine. They are carrot-shaped or cylindrical, sometimes branched, and up to 30 cm (12 in) long by 3 cm (1.2 in) wide.[1] They are a constituent of Radix Codonopsis, a mixture used in herbal medicine.[2]

Medicinal

The traditional medicinal use of Dangshen has inspired medical studies investigating the root's capabilities to treat cardiovascular, pulmonary and digestive conditions. Research into the effect of Condonopsis pilosula extract on gastric ulcers in rats showed a reduction in gastric acid production and severity of stress induced ulcers. [3]
