We often use the phrase "liver and gallbladder illuminate each other" to describe two people who are intimate and support each other. Whenever we mention this term, we can't help but sincerely admire the wisdom of the ancients. From a medical perspective, the liver and gallbladder are indeed a pair of "sharing weal and woe" organs.
In Western medicine, the blood vessels and nerves of the gallbladder all come from the branches of the liver. The gallbladder is also a good helper to the liver, as the bile secreted by the liver is stored in the gallbladder. Once we start eating, the gallbladder begins to contract, allowing bile to flow into the intestines to aid in the digestion of fats.
According to traditional Chinese medicine theory, the liver and gallbladder are interrelated, and their physiological relationship is also very close. In TCM, there is the concept of "five zang-organs and six fu-organs." The liver belongs to the sequence of the "five zang-organs," and the corresponding "fu-organ" is the gallbladder.
