凡病用药得宜未有不效,而痧症竟有得宜不效者,何也?夫痧者,热毒也。热毒用药宜凉不宜温,宜消不宜补,汤
剂入口,必须带冷,冷则直入肠胃,而肌肤血肉之间,虽有良剂,安能得至乎?此治痧者,莫先于刮之放之也。如刮之
放之,而肌肤血肉之毒已除,然后将肠、胃、脾、肝、肾、三阴之毒,用药以驱之,药固未有不效者也。然亦有刮之放
之而药有不效者,是非药不效也。盖其时虽放,而放之或有未尽;虽刮,而刮之或有未到,则是肌肤血肉之毒犹在,故
即用药,而药有不效耳。若刮已到,放已尽,而痧症犹在,则是痧毒惟在肠、胃、脾、肝、肾、三阴经络,非药将何以
治之乎。
痧症危极,昏迷不醒,即扶之不起,呼之不应,虽欲刮放而不可刮放,乃更有用药以救之,而能必其效者,何也?
盖痧症用药,必须带冷,冷虽未能即周于肌肤血肉之间,而昏迷不醒,乃痧之热毒冲于心膈,故心不能自主而昏迷。若
药带冷入口,即从心膈间顺流而下,则热毒之气在心膈间者,随药而消,故昏者复明,迷者复醒。即有不醒者,乃食积、
血、痰所阻,若能攻而下之,未有不醒者矣。此余治痧,所以又用药而必得其效也。
痧气壅遏,未有不阻塞于中,故作痛、作胀,用荆芥、防风之类,从表而散;用青皮、陈皮之类,从中而消;用枳
实、大黄之类,从大便而下;用木通、泽泻之类,从小便而行;用山楂、卜子之类,所以治其食之阻;用金银花、红花
之类,所以治其血之壅;用槟榔、蓬术之类,所以治其积之滞也。
In general, when medication is appropriate for any disease, it is invariably effective. However, in cases of Sha syndrome (an acute condition caused by heat-toxin), even with appropriate medication, there are instances where it fails to take effect. Why is this? Sha refers to heat-toxin. Medications for treating heat-toxin should be cooling rather than warming, and should promote dispersion rather than tonification. When the decoction enters the mouth, it must be cool; a cooling nature allows it to enter the intestines and stomach directly. If it is not cool, although excellent prescriptions are used, how can they reach the skin, muscles, and flesh? Therefore, in treating Sha, nothing takes precedence over scraping (Gua Sha) and bloodletting.
If, after scraping and bloodletting, the toxins in the skin, muscles, and flesh have been eliminated, one then uses medication to drive out the toxins from the intestines, stomach, spleen, liver, kidneys, and the three Yin meridians. In such cases, the medication will certainly be effective. However, there are also situations where, despite scraping and bloodletting, the medication remains ineffective. This is not because the medication itself is ineffective. It is that at the time, although scraping and bloodletting were performed, they may not have been thorough enough, or the scraping may not have reached all areas, meaning the toxins in the skin, muscles, and flesh still remain. Thus, even if medication is administered, it may fail to work. If scraping has indeed reached the necessary extent and bloodletting has been completed thoroughly, yet the symptoms of Sha persist, it indicates that the Sha toxin resides solely within the meridians of the intestines, stomach, spleen, liver, kidneys, and the three Yin channels. Apart from medication, what other method could treat this?
When Sha syndrome becomes critically severe, causing coma and unconsciousness, where the patient cannot be supported upright nor responds to calls, making scraping or bloodletting impossible, there is another method using medication for rescue that guarantees efficacy. Why? Because medication for Sha must be cool. Although cool medicine may not immediately circulate through the skin, muscles, and flesh, coma and unconsciousness occur because the heat-toxin of Sha rushes to the heart and diaphragm area, causing the heart spirit to lose control, resulting in coma. If the medicine enters the mouth while cool, it flows down smoothly from the heart and diaphragm area. Consequently, the heat-toxin qi residing in the heart and diaphragm dissipates along with the medicinal action, so the comatose regain consciousness, and the confused become alert. Even if some do not wake up, it is due to obstruction by food retention, blood stasis, or phlegm. If these can be purged downward via purgation methods, recovery of consciousness is inevitable. This is why, in my treatment of Sha, I achieve guaranteed efficacy by employing medication.
Sha qi stagnation and obstruction invariably block the middle jiao, leading to pain and distension. Use Jingjie (Schizonepetae Herba) and Fangfeng (Saposhnikoviae Radix) to disperse from the exterior; use Qingpi (Aurantii Fructus Immaturus) and Chenpi (Aurantii Pericarpium) to resolve from the middle jiao; use Zhishi (Aurantii Fructus) and Dahuang (Rhei Radix et Rhizoma) to purge downward through the large intestine; use Mutong (Akebiae Caulis) and Zexie (Alismatis Rhizoma) to guide downward through urination; use Shanzha (Crataegi Fructus) and Boluozhi (Radish Seed) to treat obstruction caused by food retention; use Jinyinhua (Lonicerae Japonicae Flos) and Honghua (Carthami Flos) to treat blood stasis; use Binglang (Arecae Semen) and Ezhu (Curcumae Rhizoma) to treat accumulation and stagnation.
