1. Origin and description

Jiaogulan is the dried whole herb of Gynostemma pentaphyllum, a climbing plant in the Cucurbitaceae family. It grows naturally and is also cultivated in cool, highland regions of Vietnam such as Hoa Binh, Lao Cai, Ha Giang, and Cao Bang. Outside Vietnam, the plant is also found in China, Japan, and other parts of Asia.

The plant has slender climbing stems with tendrils and palmately compound leaves, often with five leaflets. This explains the Vietnamese name “Ngũ diệp sâm,” meaning five-leaf ginseng.

The stems and leaves are commonly harvested and dried. Good-quality material has a natural dark green color, a mild aroma, and a Bitter first taste followed by a Sweet aftertaste.

The nickname “southern ginseng” or “five-leaf ginseng” does not mean that this plant is true ginseng. It belongs to a different botanical family and should not be considered interchangeable with Panax ginseng.
