• Wind edema has a floating pulse, with external symptoms of joint pain and aversion to wind;
• skin edema also has a floating pulse, with external symptoms of swelling in the limbs that leaves an indentation when pressed, no aversion to wind, a distended abdomen like a drum, no thirst, and should be treated by inducing sweating.
• Typical edema has a deep and slow pulse, with external symptoms of spontaneous panting;
• stony edema has a naturally deep pulse, with external symptoms of abdominal distension and fullness but no panting.
• Yellow sweat has a deep and slow pulse, body fever, chest fullness, swelling of the limbs, head, and face, and if it does not heal for a long time, it will inevitably lead to abscesses and pus.
