Sweet, cold, non-toxic. It stops various types of bleeding such as hematemesis (vomiting blood) and epistaxis (nosebleed), and eliminates damp-heat in strangury (dysuria). It treats jaundice and edema, and cures hiccups, vomiting, and urgent asthma. It promotes urination and stops Xiao Ke (wasting-thirst syndrome). Mugwort root (Imperatae Rhizoma) is found everywhere. In spring, shoots emerge, spreading on the ground like needles. In summer, white flowers appear, withering in autumn. Its roots are pure white, harvested in the sixth lunar month. The poem says: "Dew on the Imperata grass." If bamboo or wood splinters enter the flesh, burn the root to ash, mix with lard, and apply topically. It is also effective for swelling. (Verified Formula 1.)
For epistaxis, grind into powder and take with rice wash water. (2.)
For persistent hematemesis, decoct in water and take. (3.)

For mountain retreats involving fasting (Bigu), take clean roots, dry them on stones, grind into powder, and swallow with water; one will not feel hungry all day. (10.)

It addresses stagnation of cold and heat between bones, pathogenic factors of fright and epilepsy in the Liver, protrusion of red eyes and caruncles, and fire of hot dysentery and mania. It dissipates abscesses, treats sores and scabies, alleviates painful swelling of tinea pedis (Hong Kong foot), stops sore throat, eliminates night sweats, and clears irritability and heat in the Stomach. Overuse damages the Stomach Qi.
It grows in valleys of Qiqu and Yanzhou. Harvested in the second, eighth, eleventh, and twelfth lunar months. Currently produced near roadsides, with those from Wuxing being superior.
