Dang Shen: The TCM Herb for Boosting Energy and Health

Known for boosting energy and supporting digestion, it has been trusted by doctors and patients for centuries.

Later texts, like Li Shizhen’s Compendium of Materia Medica, highlighted its role in energizing the body, improving digestion, and promoting longevity. This article explores Dang Shen’s origins, plant features, varieties, benefits, modern uses, and precautions.

Plant Characteristics of Dang Shen

Dang Shen, scientifically known as Codonopsis pilosula, belongs to the Campanulaceae family. Its rhizome is long, cylindrical, and slightly curved, with a yellowish-white or grayish-yellow surface marked by grooves. The plant’s slender stem bears alternate, oval-shaped leaves with serrated edges. From July to September, it produces bell-shaped, light yellow flowers with purple spots. By September to October, these develop into capsule fruits that split open when ripe.

Dang Shen grows in Northeast, North, and Northwest China, particularly in Shanxi, Shaanxi, and Gansu, at altitudes of 1,000–3,000 meters. It thrives in warm, humid climates, often found on mountains, hills, forest edges, or shrublands. The herb is cold- and drought-resistant, adapting well to various environments.
