*Shenghui Fang*: For weaned infants and children suffering from rash and smallpox diseases, the initial stage often resembles Taiyang disease (a syndrome caused by pathogenic factors affecting the Taiyang meridian). The complexion and limbs are both red, with high fever, headache, pain in the waist and back, coldness in the feet, and yellow eyes. The pulse is mostly surging and rapid, extremely large and irregular; urine is dark red and scanty, and stool is mostly constipated. As soon as the color of the limbs and the pulse indicate a rash or smallpox disease, but the pathogen has not yet attacked the skin pores to emerge, medication can be administered. Harmonize the Zang-Fu organs, and use methods to unblock and guide downward. If the rash has already formed at the skin pores and seems slightly ready to emerge, do not use unblocking and purging methods. However, if the rash is too abundant or the pustules contain pus and fluid, unblocking and guiding downward may be used.

*Wangshi Shouji*: Those who discuss sores and rashes generally rely on ancient texts, considering it incorrect to use unblocking and guiding methods immediately upon detection. They cite Qian Yi's theory that treating with warm and cool medicines without reckless purging is correct. Thus, they believe that the reason modern children with sores and rashes survive without sudden death is due to Qian Yi's merit. Since children's intestines and stomachs are delicate, reckless purging leads to internal deficiency, causing heat pathogens to retreat inward, which can be fatal. Therefore, deaths caused by the inversion of sores and rashes are attributed to the fault of purging. This view is indeed correct. However, failing to examine the words leads to losing their true meaning. It is unknown that what ancient texts call "unblocking and guiding" means first harmonizing Yin and Yang, regulating Ying and Wei (nutritive and defensive Qi), and then benefiting the Zang-Fu organs, so that heat pathogens gradually resolve. It also states: Infants naturally have excess Yang and deficient Yin. When the Qi of Zang-Fu organs and Yin-Yang becomes rebellious, bowel movements and urination are often blocked. Upon detecting this disease, one should immediately apply unblocking and guiding, resulting in a mild condition. Once the rash or smallpox has emerged, unblocking and guiding should not be used. Does this ever imply using purging when the rash emerges? Moreover, there is a vast difference between unblocking/guiding and purging. Unblocking and guiding uses light and cool herbs to gently promote drainage, such as Qingdai (Indigo Naturalis) and Huanglian (Coptidis Rhizoma); purging uses harsh and fast-acting drugs to forcefully drain downward, such as Badou (Crotonis Fructus) and Mangxiao (Natrii Sulfas); they cannot be compared. Ignorant physicians fail to understand the ancient intent and confuse unblocking/guiding with purging, leading to errors. Did they harmonize Yin and Yang and regulate Ying and Wei before purging? Was the child suffering from blocked urination and defecation? The phrase "upon detection" refers to the time when sores and rashes have not yet appeared. When physicians purge, do they know whether the sores and rashes have emerged or not? Do they know the saying "once the rash emerges, do not unblock or guide"? Often, ignorant physicians see sores and rashes and administer purging, claiming it helps them emerge quickly, thus causing many errors. Qian Yi stated that this is an epidemic disease, treatable only with warm and cool medicines, avoiding reckless purging and attacking/dispersing. Did he ever say such conditions should not be unblocked or guided? Reckless purging is not equivalent to unblocking and guiding. Even Chu Yushi misunderstood the intent, comparing sores and rashes to Taiyang disease and using draining medicines when reaching the Yangming stage, not realizing that for Taiyang disease reaching Yangming, purging is appropriate. Since ignorant physicians do not understand the ancient intent, and even skilled physicians verify these statements without doubting their correctness, I specifically clarify this. At the beginning of sores and rashes, if these symptoms exist, unblocking and guiding are suitable, but purging must be avoided.

*Shenghui Fang* treats children with excessive heat toxicity causing rash and smallpox, detected early in onset. This formula is suitable.
Take Huanglian (Coptidis Rhizoma) one liang, remove roots, crush, and sieve into powder. Take one qian per dose, decoct with one small cup of water until reduced to half a cup, remove dregs. Administer warm, adjusted according to the child's age and size, at any time.

Another formula from *Shenghui Fang*:
Take Boshi Qingdai (Persian Indigo Naturalis) the size of a date pit, mix with water and take orally. (Same as in *Zhen Dou Lun*, mixed with warm knife-sharpening water.)

*Danggui San* from *Zhen Dou Lun*:
Chuan Danggui (Angelicae Sinensis Radix) (one liang), Gancao (Glycyrrhizae Radix et Rhizoma) (one fen).
Grind into fine powder. Take two qian per dose, decoct with one medium cup of water and ten grains of Douchi (Fermented Soybean) until reduced to six-tenths, remove dregs. Dosage depends on the child's age. Stop when gentle drainage occurs. Drink Gancao juice (Licorice Juice) cold daily. Adjust dosage for children aged one to three years.

*Zhen Dou Lun*: For cases where sores have not yet suppurated, with dryness in the heart and diaphragm and restlessness during sleep.
Decoct Heidou (Sojae Semen Nigrum) in water, warm, and drink slowly to relieve symptoms.

*Zhen Dou Lun* again: For epidemic sores and rashes, urgently prepare Dou Tang (Bean Decoction) in advance.
Xiaodou (Adzuki Bean), Heidou (Black Bean), Lüdou (Mung Bean) (each half sheng), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried) (one liang).
Decoct with nine sheng of water until beans are cooked. Drink freely on an empty stomach daily. After seven days, the sores and rashes will likely emerge smoothly.
