What causes liver deficiency and gallbladder fever?

The main causes of liver deficiency and gallbladder heat include emotional failure, improper diet, yin deficiency, etc., specifically as follows:

TCM believes that emotional failure, depression and fire will seriously damage the liver, resulting in liver weakness, resulting in excessive heat, and because the liver and gallbladder are adjacent to each other, most of the liver fire will preferentially affect the gallbladder, and then form liver deficiency and gallbladder heat. Secondly, liver fire can also be caused by stomach fire, and stomach fire is more common cause is improper diet. In addition, a small number of people suffering from yin deficiency, because yang qi can not be restrained, so excess yang qi will form internal fire, while gradually affecting the functions of liver, gallbladder and other organs.
