论述说：《内经》记载有口苦的病，称为胆瘅。胆是中正之官，清净之腑，十一脏的功能发挥都取决于胆，咽部是胆气运行的通道。如果多次谋虑而不能决断，就会导致胆虚，胆气上溢，从而引起口苦。胆主藏精气而不妄泻。如今多次谋虑而犹豫不决，使得原本清净的胆气变得浑浊并受到扰乱。因此胆气上溢，其症状表现为口苦。经书所说的“是动则病口苦”，就是因为胆气发生变动所致。

It is stated in the discussion: The *Neijing* (Classic of Internal Medicine) records that a disease manifesting as bitter taste in the mouth is called Dan Dan (Gallbladder Heat). The Gallbladder is the official of justice and integrity, a pure and clear organ, from which the functions of the eleven zang-fu organs depend. The pharynx serves as its pathway. If one frequently deliberates but fails to make decisions, it leads to Gallbladder deficiency with Qi overflowing upwards, resulting in a bitter taste in the mouth. The Gallbladder stores essence and does not discharge recklessly. Now, frequent deliberation without resolution causes the pure and clear state to become turbid and disturbed. Therefore, Qi overflows upwards, and the symptom manifests as a bitter taste in the mouth. The classic states "when the channel is moved, there is disease of bitter taste in the mouth," because this is due to the movement of Qi.
