Bai Niuxi (Achyranthes Bidentata Root, White Variety), also known as Taiji Cao (Taiji Grass), Gou Ru Zi, Gou Ru Zi, and Gou Duo Zi. It tastes bitter and sour, and its nature is warm. It tonifies the Liver (Zang organ governing storage of blood and ensuring smooth flow of Qi), promotes blood circulation, breaks up blood stasis masses, and clears heat from the blood level. It treats amenorrhea (absence of menstruation), abdominal pain, postpartum fever, deficiency-type labor fever (low-grade fever due to postpartum debility), retrograde menstruation in unmarried women, epistaxis (nosebleed) and hematemesis (vomiting blood), red leukorrhea and white leukorrhea, urgent and dribbling urination, excess cold-dampness, pain in bones and tendons, strengthens tendons and bones, treats carbuncles and sores with hot-toxic redness and swelling, parotitis and tonsillitis, male bloody stranguria (hematuria), turbid urine with red and white discharge, and female red and white leukorrhea. However, it has an abortifacient effect; pregnant women should avoid taking it. Water and wine are used as guides for administration.
It is also indicated for abdominal distension, loss of appetite, pain caused by Liver Qi stagnation, continuous lochia, and postpartum deficiency syndromes.
Formula: Bai Niuxi Pi (Cortex of Achyranthes Bidentata Root, 1 qian), Yin Chai Hu (Radix Stellariae Dichotomae, 1 qian), Huang Qin (Scutellariae Radix, 1 qian), Bai Fu Ling (Poria, 1 qian). Decoct in water and take mixed with Tong Bian (urine of a healthy young boy). This formula also treats five types of deficiency-heat in women, irregular menstruation, bleeding during menstruation or erratic menstrual flow, leakage of white leukorrhea, dribbling urination, heat in the palms, aversion to cold in the afternoon, night fever with irritability and thirst, sweating with cessation of fever at dawn, dizziness, tinnitus, palpitations, soreness and weakness of the four limbs, tasteless food, and diminished spirit upon waking early. If these deficiency signs appear, modify this formula accordingly. For irritability and thirst, add Mai Dong (Ophiopogonis Radix) and Dan Zhu Ye (Lophatheri Herba); for diarrhea, add Zhun Yao (Dioscoreae Hypoglaucae Rhizoma), Lian Zi (Nelumbinis Semen), and one spoonful of Nuo Mi (Oryza Sativa Glutinosa); for cough, add Tian Dong (Asparagi Radix), Chen Pi (Citri Reticulatae Pericarpium), and Bai He (Lilii Bulbus); for wheezing, add Xing Ren (Armeniacae Semen Amarum), Dou Ling (Stemonae Radix), Su Zi (Perillae Fructus), Gua Lou Ren (Trichosanthis Semen), and Chen Pi; for hemoptysis, add Mao Gen (Imperatae Rhizoma), Bian Bo (Platycladi Cacumen), and Ku Ma Cai Zhi (juice of Crotalaria Mucronata); if coughing with blood streaks accompanied by dizziness and tinnitus, add Jing Jie Sui (Schizonepetae Spica); for palpitations and insomnia, add Zao Ren (Ziziphi Spinosae Semen), Long Yan Rou (Longan Arillus), Bai Zi Ren (Platycladi Semen), and Yuan Zhi (Polygalae Radix); for chest and diaphragm distension, add Shen Qu (Massa Medicata Fermentata), Hou Po (Magnoliae Officinalis Cortex), and Sha Ren (Amomi Fructus); for loss of appetite, add Lian Zi and Shen Qu.

For women who have been unable to conceive for a long time due to deficiency of the Ren and Du vessels leading to infertility, as well as for leukorrhea, the treatment method is to take it once or twice after menstruation ends to achieve pregnancy.
Formula: Bai Niuxi (2 qian), Di Gu Pi (Lycii Cortex, 2 qian). Decoct in water and take mixed with Tong Bian and Shui Jiu (water and wine).

Formula: Bai Niuxi (3 qian), Xiao Gong Ji (One small rooster, eviscerated). Place the herbs inside the chicken cavity, optionally adding salt, roast until soft and tender, and take on an empty stomach. Take once after each menstrual period to induce pregnancy. If the patient does not eat chicken, using Bai Niuxi alone (3 qian) decocted in water and taken with Shui Jiu is also effective.
(Attached Case History) In the past, a maiden surnamed Wang suffered Liver injury from depression and anger, compounded by wind-cold invasion. After a long duration, she developed tidal fever and aversion to cold, gradually progressing to amenorrhea, emaciation, and a chronic deficiency-consumption syndrome.
