What is the cause and pathogenesis of functional uterine bleeding according to traditional Chinese medicine?

"Lan Feng is sick." This sentence from colleague Xiao Tang immediately attracted the attention of other colleagues in the office. "What's wrong? What's wrong with Lan Feng?" Everyone asked Xiao Tang in unison.

"I heard it was functional uterine bleeding?" Xiao Tang answered vaguely.

"Dysfunctional uterine bleeding? What are the symptoms of this disease? How is it caused?" asked my colleague Lan Lan in confusion. "Oh, it seems to be menstrual disorder, and the amount of bleeding is very heavy--" my colleague Xiao Dong seemed to know something about this disease.

"That's right. It is said that Lan Feng suffered from anemia due to frequent heavy bleeding. As for what caused it, I searched the Internet for a long time but still couldn't figure it out." Xiao Tang quickly added.

"Then what medicine can cure it?" asked my colleague Xiaotong. "It seems like he's seeing a Chinese doctor and taking Chinese medicine." Xiao Tang replied.

"Oh, do you know what Chinese medicine doctors think causes this disease?" Xiaoping, who had been silent all this time, suddenly asked a question, making everyone look at each other in confusion, not knowing how to answer.

According to TCM etiology and pathogenesis, the occurrence of this disease is mainly due to damage to the Chong and Ren meridians. Blood heat, kidney deficiency, spleen deficiency, blood stasis, etc. caused by various reasons can damage the Chong and Ren meridians. When the Chong and Ren meridians are damaged, they cannot control the menstrual blood, so the blood flows out of the uterus at an untimely time. "The kidney governs reproduction", "the kidney is the source of life", "the menstruation originates from the kidney", and dysfunctional uterine bleeding is often closely related to the kidney, and is also related to the liver, spleen, and blood stasis.
