Soaked in wine and baked for use. Used with Rehmanniae Radix (Shu Di Huang, 熟地黄) as a guiding herb; contraindicated with Polyporus Umbellatus (Leishen, 雷丸).
Pungent, bitter, slightly warm, non-toxic. Regulates tendon and bone fractures and injuries; treats metrorrhagia (abnormal uterine bleeding) and leukorrhea with dripping blood. Breaks up blood stasis to relieve lower back pain; warms the uterus to reduce urinary frequency.
[Indications] Fetal restlessness causing vaginal bleeding (Lou Tai).
Conditions of spermatorrhea, intestinal wind with bloody dysentery, and bloody diarrhea. It is an essential medicine for obstetric and gynecological disorders and also a good remedy for surgery.
It grows in valleys everywhere. The stem has four edges, resembling Boehmeria nivea (Ramie), with leaves growing opposite each other. It flowers in April, resembling Leonurus japonicus (Motherwort) flowers, and its root resembles Cirsium japonicum (Da Ji). Since the Han Dynasty, people have mistakenly used Cirsium japonicum (Da Ji) as Dipsaci Radix (Xu Duan), an error that has persisted for a long time. Furthermore, those that are reddish in color, slender, and emit dust-like powder when broken are considered superior; those produced in Sichuan are the best.
