Codonopsis pilosula, also known as Dangshen (Chinese: 党参; pinyin: Dǎngshēn), is a perennial species of flowering plant in the bellflower family.

The ovate leaves are up to 7.3 cm (3 in) centimeters long and are usually coated with short hairs.

The bell-shaped flower is about 2 cm (0.8 in) long and wide and is yellow-green with purple spots inside.

[2] 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.
