The liver is the most important organ after the heart. The liver stores and regulates the blood and is responsible for nourishing every cell in our body. Every part of the body depends on blood from the liver for nourishment and sustenance. Since estrogen and androgen are both cell division stimulators, elevation of their levels in the blood due to the liver's failure to remove them efficiently can cause their accumulation in tissue. This in turn may lead to abnormal growths such as uterine fibroids, ovarian cysts, endometriosis, breast cysts and breast cancer, prostate enlargement or prostate cancer.
Excessive estrogen is also the most common cause of painful menstruations.
The liver also regulates body functions which affect emotional and mental activities. In a diseased condition, the liver's blood storage and regulatory functions are affected, and bleeding or clots can result. When liver blood is deficient, nourishment to tendons and blood vessels is curtailed, the joints become stiff, and muscles become spasmodic and numb. Blood deficiency in the liver may even lead to stroke, dizziness, headaches, tinnitus, deafness, fainting or convulsion. If the liver is affected by stress or unhappy feelings, its vitality may be repressed and the sides hurt, and hiccups or hernia may develop.
