Guanzhong is the root of an ancient fern originally recorded in the Shen Nong bencao jing. It grows in the damp environment of the wild rainforests of China’s Northeast. As such, it naturally belongs to the class of cold and bitter medicinals, but most notably exhibits a broad spectrum anti-toxin effect.
Guanzhong is the root of an ancient fern originally recorded in the Shen Nong bencao jing. It grows in the damp environment of the wild rainforests of China’s Northeast. As such, it naturally belongs to the class of cold and bitter medicinals, but most notably exhibits a broad spectrum anti-toxin effect.  While it is described as “mildly toxic” in the ancient materia medica, it is our experience that as long as the correct species of Mianma Guanzhong (Dryopteris) is used, Guanzhong is generally an herb exhibiting high alchemical stability (suitable for long-term use) for patients suffering from Gu syndrome and various toxic acumulations. In addition, it is generally a superior choice in cases of external wind invasion with heat and toxicity when compared to Banlangen (Isatis root), the conventional anti-virus herb of modern Chinese herbalism.
Classical Pearls’ Guanzhong is sourced close to the Siberian border from wild-crafted Mianma Guanzhong in the pristine forests of Heilongjiang Province.
