General principles: In spring and summer, it is appropriate to induce sweating.
When inducing sweating, it is desirable for the sweat to be evenly distributed over the hands and feet; profuse sweating throughout the body is better, but excessive dripping sweat should be avoided. If the disease does not resolve, sweating may be induced again. However, excessive sweating leads to Yang deficiency; if Yang is deficient, repeated sweating must not be performed.
When inducing sweating, stop once the pathogen is addressed (Zhongbing); there is no need to consume the entire dose.
In Taiyang disease (Disease of the Taiyang Channel), if the pulse is floating and rapid, inducing sweating is appropriate.
In Taiyang disease, if the pulse is floating, large, and rapid, inducing sweating is appropriate.
In Yangming disease (Disease of the Yangming Channel), if the pulse is slow, there is abundant sweating, and slight aversion to cold, indicating that the exterior syndrome has not resolved, inducing sweating is appropriate.
In Yangming disease, if the pulse is floating and rapid, inducing sweating is appropriate. [Note: Textual anomaly in source]. In Taiyang disease, where there is constant slight sweating, inducing sweating is more appropriate.
Generally, if the pulse is floating and tight, floating indicates Wind, and tight indicates Cold; inducing sweating is appropriate.
In Taiyang disease, if mild wheezing occurs after purgation, the exterior syndrome has not resolved, and inducing sweating is appropriate.
In Taiyang disease, if there is fever, sweating, and aversion to cold, inducing sweating is appropriate.
Generally, if the pulse is deep and rapid, indicating an interior disease, sweating must not be induced due to the lack of Yang (insufficient Yang energy/fluids to generate sweat).
Generally, if the Chi position (cun-kou pulse at the wrist) pulse is slow, sweating must not be induced due to insufficiency of Ying and Wei (Nutritive and Defensive Qi) and blood deficiency.
Generally, if the pulse is soft and weak, sweating must not be induced.
Generally, if there is obstruction in the throat, sweating must not be induced.
Generally, if there is "Qi movement" (abdominal pulsation/mass) on the left or right sides of the abdomen, sweating must not be induced.
Generally, if there is Qi movement above, sweating must not be induced; inducing sweating causes Qi to rush upward and lodge at the heart tip.
Generally, if there is Qi movement below, sweating must not be induced; inducing sweating causes severe mental restlessness, dizziness, aversion to cold, and vomiting after eating.
Generally, if there is any Qi movement with a weak pulse, sweating must not be induced; inducing sweating leads to difficult urination, dryness of the bladder, and restlessness.
Generally, if the throat is dry, sweating must not be induced.
Generally, if there has been blood loss, sweating must not be induced; inducing sweating will inevitably lead to mental confusion and restlessness.
Generally, if accumulated heat resides in the Zang organs, sweating is not suitable; inducing sweating will inevitably cause vomiting, mouth ulcers, and sores.
Generally, in cases of dysentery with undigested food and water, attacking the exterior is contraindicated; inducing sweating will inevitably cause abdominal distension and coughing. If urination is free, attacking the exterior is contraindicated; inducing sweating will lead to rebellious Qi.
For those who vomit after taking decoctions, stop once the pathogen is addressed; there is no need to finish the entire dose.
General principle: In spring and summer, it is appropriate to induce vomiting. For diseases where the head does not have severe pain, the Cun Kou (radial artery) pulse is floating, there is chest fullness and oppression, Qi rushes up to the throat, and breathing is obstructed, this indicates Phlegm-Fluid retention, and emesis is appropriate.
If there is chest and epigastric fullness and solidity,郁 (depression) and pain in the chest, inability to eat, excessive saliva, diarrhea, a slow pulse that is paradoxically reversed, and a rapid Cun Kou pulse, emesis is appropriate.
If the patient has cold hands and feet, a knotted pulse (Jie Mai), irritability in the lower chest/epigastrium, hunger but inability to eat, and the disease is located in the chest, emesis is appropriate.
For Shanghan (Cold Damage) presenting with chest fullness, rebellious Phlegm-Qi, dry retching, hot cough, and Lung congestion with purulent sputum, emesis is appropriate.
For retained food stagnating in the stomach tube, emesis is appropriate.
