Panax notoginseng is a pearl in Chinese herbal medicine. It is recorded in Compendium of Materia Medica, a pharmaceutical work in the Qing Dynasty: "Ginseng is the first to tonify qi, and Sanqi is the first to tonify blood, which has the same taste, so it is called Sanqi, which is the most precious of Chinese herbal medicines." The famous Chinese patent medicines "Yunnan Baiyao" and "Pien Tze Huang" are made of notoginseng as the main raw material.
Panax notoginseng is a perennial herb of Araliaceae. It was named Sanqi because it was dug three to seven years after sowing. Each plant has three petioles and each petiole has seven leaves. Its stems, leaves and flowers can be used as medicine.
