Description: Rhizoma polygonati, or known as Polygonatum and Huang Jing in mandarin, has long been considered as an amazing Chinese herb that is good at prolonging life. No wonder Taoists claim that long-term consumption of this herb can make a person become immortal. Myths aside, it is still one of miracle herbs that can be edible on daily basis. As a matter of fact, today it is still frequently used as a qi tonic by soaked in wine or stewed with chicken. As you know, generally tonics may more or less spoil your appetite but Polygonatum is one of the exceptions thanks to its relatively mild nature. That’s to say, its tonic power won’t release all at one but steadily and slowly and it won’t dull your appetite like other tonics. That’s the reason why it has an extensive medicinal uses and so many popular dish recipes. Most importantly, unlike the aloft Cordyceps Sinensis (Dong Chong Xia Cao) and Ren Shen (Ginseng), it is so inexpensive that all can afford it.
Modern biochemical research shows that Huangjing contains a complex array of sugars, starches, vitamins, minerals and antioxidants. At the same time, it has been identified as one of the most effective antifungal agents within the Chinese materia medica.

The flavor of fresh and unprocessed Huangjing is pungent and will irritate the throat when imbibed directly. Only when steamed/dried thoroughly and repeatedly will the herb develop the desired affect of nourishing and tonifying the kidney. The best harvest time is in spring and autumn. After the digging, remove the fibrous roots, wash with water, put in boiling water to scald slightly or steam thoroughly, dry, and then cut into thick slices. Dragon Tea House sources its Huangjing in the remote mountains that separate the provinces of Shaanxi and Sichuan in SW China. Roots are wild-crafted by selectively harvesting plants that are at least 5 years old. Before extraction, traditional paozhi techniques are applied by steaming the large roots nine times. The flavor of prepared Huangjing is sweet and its consistency is thick and sticky.
