What is special about this herbal remedy called "more precious than ginseng" that many people brew and drink daily, becoming healthier?

What is Gynostemma pentaphyllum and what are its characteristics?

Gynostemma pentaphyllum is also known as the immortality herb (China), fukuyinso (Japan), southern ginseng, five-leaf ginseng, etc. Its scientific name is Gynostemma pentaphyllum, a plant in the gourd family (Cucurbitaceae).

According to research, Gynostemma pentaphyllum (jiaogulan) is a plant that grows wild in sparse forests with low humidity and cool climates, such as in Korea, Japan, and China. In Vietnam, it is widely found in the Fansipan mountain region of Sa Pa and the limestone mountains of Hoa Binh province.

Although this medicinal herb has long been popular in countries like China and Japan with specialized remedies and miraculous benefits, discoveries, harvesting, and research in Vietnam have shown that the quality of Jiaogulan found in our country is comparable to the two species found in China and Japan.

Gynostemma pentaphyllum is a herbaceous climbing vine with simple tendrils in leaf axils for climbing. Its leaves are palmately compound, spreading out like fingers on a hand. Each stem bears 5 to 7 leaves, or sometimes 9. The leaf surface is rough, with a dark green upper side and a lighter underside.

Gynostemma pentaphyllum flowers grow in panicle-like clusters, consisting of numerous small white flowers whose petals spread out separately in a star shape, with 3 styles on the ovary. The fruit is spherical, about 5–9 mm in diameter, turning black when ripe.

Gynostemma pentaphyllum is divided into 3 types based on leaf characteristics:

3-leaf type: 3-leaf Jiaogulan usually has 3 leaflets at the largest part of the vine; it is rarely used, has a bland taste, and is less fragrant than the other types.

5-leaf type: 5-leaf Jiaogulan is the most widely used because it has the best efficacy. This type has a mild aroma; when dried and brewed, it tastes bitter initially, followed by a pleasant sweet aftertaste.

7-leaf type: 7-leaf Jiaogulan is quite similar to the 3-leaf type, but tastes more bitter and is harder to drink.

According to traditional medicine, Jiaogulan has a bitter, slightly sweet taste and a cool nature; it enters the lung, spleen, and kidney meridians. This medicinal herb clears heat, detoxifies, tonifies qi, strengthens the spleen, nourishes yin, and resolves phlegm to relieve coughs. As a result, Jiaogulan is often used to support the treatment of conditions such as hepatitis, dyslipidemia, chronic gastroenteritis, chronic bronchitis, general weakness, and cough with phlegm...
