Yellow-water sore (impetigo): If it spreads from the mouth to the limbs, it can be treated; if it spreads from the limbs to the mouth, it cannot be treated.

bubble_chart Note:

The term "yellow-water sore (impetigo)" refers to a condition where the sores spread continuously and persistently. When it spreads from the mouth to the limbs, it is considered mild because it moves from the inside outward, hence it is said to be treatable. When it spreads from the limbs to the mouth, it is considered severe because it moves from the outside inward, hence it is said to be untreatable. "Spreading continuously" here is akin to what is now referred to as pestilent qi or similar conditions.
