Bajhen Yimu Pill is a Chinese preparation composed of Radix Rehmanniae, Radix Angelicae Sinensis, Radix Codonopsis Pilosulae and Rhizoma Atractylodis Macrocephalae. Its main action is to tonify Qi and nourish Blood to regulate menstruation, and its therapeutic effect can vary greatly due to different causes of amenorrhea. If a woman is suffering from amenorrhea due to environmental changes or stress, the effect of taking Bajhen Yi Mu Wan is better. However, if a woman has amenorrhea due to polycystic ovary syndrome, which causes no ovulation, the effect of taking Bajhen Yi Mu Wan is usually poor and may not have any effect. If a woman is suffering from amenorrhea due to endometrial adhesions caused by abortion, she does not need to take Bajhen Yi Mu Wan, which is not effective at all.
