向余荆人，年近四旬，于八月终初寒之时，偶因豪雨后中阴寒痧毒之气，忽于二鼓时，
上为呕恶，下为胸腹搅痛，势不可当挡时值暮夜，药饵不及，因以盐汤探吐之，痛不为减，
遂连吐数次，其气愈升，则其痛愈剧，因而上塞喉嗌，甚至声不能出，水药毫不可入，危在
顷刻间矣。余忽忆先年曾得秘传刮痧法，乃择一光滑细口瓷碗，别用热汤一钟，入香油一二
匙，却将碗口蘸油汤内，令其暖而且滑，乃两手覆托其碗，于病者背心轻轻向下刮之，以渐
加重，碗干而寒，则再浸再刮。良久，觉胸中胀滞渐有下行之间，稍见宽舒，始能出声。顷
之，忽腹中大响，遂大泻如倾，其痛遂减，幸而得活，泻后得睡一饭顷，复通身瘙痒之极，
随发出疙瘩风饼如钱大者，不计其数，至四鼓而退。愈后，细穷其义。盖以五脏之系咸附于
背，故向下刮之，则邪气亦随而降。凡毒瓦斯上行则逆，下行则顺，改逆为顺，所以得愈。虽
近有两臂刮痧之法，亦能治痛，然毒深病急者，非治背不可也！至若风饼疙瘩之由，正以寒
毒之气，充塞表里，经脏俱闭，故致危剧。今其脏毒既解，然后经气得行，而表里俱散也。
可见寒邪外感之毒，凡脏气未调，则表亦不解，表邪未散，则脏必不和，此其表里相关，义
自如此。故治分缓急，权衡在人矣。继后数日，一魏姓者，亦于二鼓忽患此症，治不得法，
竟至五鼓痛极而毙，遇与不遇，此其所以为命也。
我的妻子，年龄接近四十岁，在八月底初寒的时候，偶然因为大雨之后侵入了阴寒痧毒之气，忽然在二更天时，向上出现呕吐恶心，向下出现胸腹部绞痛，病势猛烈无法阻挡。当时正值夜晚，药物来不及准备，于是用盐汤催吐，疼痛没有减轻，接着连续呕吐几次，气机更加上逆，那么疼痛就更加剧烈，因此向上堵塞咽喉，甚至声音发不出，水和药完全不能进入，生命危在旦夕。我突然想起早年曾得到秘传的刮痧法，于是挑选一个光滑细口的瓷碗，另外用热汤一杯，加入香油一两匙，将碗口蘸入油汤中，让它既温暖又滑润，然后双手托住碗底，在病人背部轻轻向下刮拭，逐渐加重力度，碗变干变冷时，就再浸泡再刮。过了很久，觉得胸中的胀滞感渐渐有下行的趋势，稍微感到宽舒，才能发出声音。过了一会儿，忽然腹中大声响动，于是大便大量排出如倾泻一般，疼痛随之减轻，侥幸得以存活。泻后睡了一顿饭的工夫，随后全身瘙痒至极，随即发出像铜钱大小的疙瘩风疹，数量不计其数，到四更天时消退。痊愈后，仔细推究其中的道理。大概是因为五脏的联系都附着于背部，所以向下刮拭，邪气也随着下降。凡是毒瓦斯上行则逆乱，下行则顺遂，改变逆乱为顺遂，所以能够痊愈。虽然近来也有两臂刮痧的方法，也能治疗疼痛，但是毒深病急的情况，不刮背部是不行的！至于风疹疙瘩的由来，正是因为寒毒之气充塞表里，经络脏腑全部闭塞，所以导致病情危重剧烈。现在脏毒既然解除，然后经气得以运行，表里之邪都消散了。可见外感寒邪之毒，凡是脏气没有调和，则表邪也不解；表邪没有散除，则脏腑必然不和，这是表里相关的关系，道理自然如此。所以治疗要分缓急，权衡在于医者。此后几天，有一位姓魏的人，也在二更天忽然患此症，治疗不得法，竟然在五更天因疼痛极度而死亡。遇到或不遇到（正确的治疗方法），这就是所谓的命运啊。
My wife, nearing forty years of age, at the end of August when the cold first set in, accidentally contracted Yin-cold Sha-toxin Qi after a heavy rain. Suddenly, during the second watch (9:00 PM - 11:00 PM), she experienced upward vomiting and nausea, and downward twisting pain in the chest and abdomen, with a momentum that was unstoppable. At that time, it was night, and medicines were not readily available, so I used salt water to induce vomiting. The pain did not subside; instead, after several more episodes of vomiting, the Qi rose further, causing the pain to intensify. Consequently, the obstruction blocked her throat, rendering her unable to speak or take any food or medicine, placing her life in imminent danger.
I suddenly recalled a secret scraping method (Gua Sha) I had obtained years prior. I selected a porcelain bowl with a smooth, narrow rim, took a cup of hot water, added one or two spoons of sesame oil, and dipped the rim of the bowl into the warm oily water to make it both warm and slippery. Holding the bowl with both hands, I gently scraped downwards along the patient's back, gradually increasing the pressure. When the bowl became dry and cold, I would re-dip and scrape again. After a while, she felt the distension and stagnation in her chest gradually moving downward, experiencing slight relief, which allowed her to produce sounds. Shortly after, there was a loud rumbling in her abdomen, followed by a profuse diarrhea, after which the pain subsided. She fortunately survived. After the purgation, she slept for the duration of a meal. Subsequently, her entire body became extremely itchy, and numerous wheals resembling coins erupted all over her skin, disappearing by the fourth watch (1:00 AM - 3:00 AM).
After recovery, I carefully analyzed the underlying principle. It is because the connections of the Five Zang Organs are attached to the back; therefore, scraping downwards causes the pathogenic factors to descend as well. Generally, if toxic vapors ascend, they cause rebellion; if they descend, they follow the natural order. Changing rebellion to compliance is why healing occurred. Although there is a recent method of scraping the arms, which can also relieve pain, in cases of deep-seated toxins and acute illness, scraping the back is indispensable. As for the origin of the wheals and bumps, it is precisely because the cold-toxic Qi filled the exterior and interior, closing the meridians and organs, leading to critical severity. Now that the internal toxin has been resolved, the Qi of the meridians can circulate, and the pathogens in both the exterior and interior dissipate. This demonstrates that for external cold-toxic invasion, if the Zang Qi is not harmonized, the exterior will not be released; if the exterior pathogens are not scattered, the Zang organs will inevitably be disharmonious. This interrelationship between the exterior and interior follows this inherent logic. Thus, treatment must distinguish between urgency and non-urgency, relying on the physician's judgment.
A few days later, a man surnamed Wei suffered from the same condition suddenly during the second watch. Due to improper treatment, he died at the fifth watch (3:00 AM - 5:00 AM) from extreme pain. Whether one encounters the correct treatment or not is what we call destiny.
