痈疮中最为凶险恶毒的病症，没有比发背更严重的了。然而，若能辨别其阴阳属性，治疗便不难；若不知辨别阴阳，即使是普通的疮痈也无法取得疗效，更何况是容易治疗的病症呢？
因此，对于痈疮病症，只应当询问它是阴证还是阳证，不应当计较它病情轻重如何。大抵各种痈疽疮症在初发之时，出现疼痛、发冷、发热等症状，多数属于阳证。阳证初起必然红肿高突，患者因疼痛而呼号叫喊，这是不可避免的。若是阴证则不然，虽然也会发冷发热，但疼痛反而觉得较轻。初发之时必定呈现无数小疮头，用以迷惑世人，整体态势平坦而无高突之状，面色必定晦暗，不像阳证那样面红。治疗时稍有不慎，生死就在顷刻之间，怎能不谨慎呢？
阳证的疮，是由于火气有余不能发泄，或因饮用凉水、水浆导致气机拥遏而形成的阳毒。阴证的疮，必定生于富贵之人，或生活繁华且兼有忧郁，或生气恼怒且伴有房劳过度。体内阴液既已干枯，内火自然炽盛，蕴藏的毒邪实在深重，一旦溃发，岂能用细小的轻微药量期望其保全性命呢？这与阳证的治疗方法大不相同。然而，阴阳虽有区别，有毒瓦斯（致病因素）总归没有太大差异。
我现在确立一方，统管阴阳痈疽的各种疮症，无不神效。只是阳证减小剂量，阴证增加药味。方名“阴阳通治丹”。如果是阴证，各药加倍，再加附子一钱即可。其余不可乱加。此方的妙处在于金银花，因为这一味药既是补阴的妙品，又是散邪解毒的圣药。然而如果不大量使用，则药力薄弱而疗效浅显，所以我用到三两之多。
阳证为何适宜使用此方？因为补阴正是为了助益阳气之不足，阳生于阴，原本就有妙用。若是阴证，尤其适宜使用，加倍则药力大而气专，加入附子以通达经络，无经不入，引导当归、甘草等药物同群共济，更容易奏效。倘若世人不听我的劝告，因循守旧延误治疗，必然导致阴证变成坏症，而阳证也转变为阴证，从而不可救治，这就太可怜了。
Among the symptoms of carbuncles and sores, none is more fierce and malignant than "Fa Bei" (Back Carbuncle). However, if one distinguishes between Yin and Yang syndromes, treatment is not difficult; if one fails to distinguish Yin and Yang, even ordinary sores will fail to respond to treatment, let alone those that are easier to treat.
Therefore, regarding carbuncles and sores, one should only inquire whether it is a Yin syndrome or a Yang syndrome, rather than calculating its severity. Generally, when various carbuncles, ulcers, and sores first appear, accompanied by pain, chills, and fever, they are mostly Yang syndromes. At the onset of a Yang syndrome, there is inevitably redness, swelling, and protrusion, and the patient cannot avoid crying out in pain. In contrast, a Yin syndrome is different; although chills and fever may occur, the pain feels relatively lighter. At the initial stage, numerous small pustules must appear to deceive observers, with a generally flat surface lacking protrusion, and the facial complexion must be dark, unlike the red face seen in Yang syndromes. Treatment requires great caution, as life and death can turn on a dime.
A Yang syndrome sore arises from excess Fire that cannot be vented, or from the obstruction caused by drinking cold water or beverages, resulting in Yang Toxin. A Yin syndrome sore typically occurs in wealthy individuals who lead luxurious lives compounded by depression, or those who suffer from anger and excessive sexual activity. Since the internal Yin fluids are depleted, internal Fire blazes fiercely, and the accumulated toxin is profound. Once it erupts, how can one expect survival with minor doses? This differs significantly from the treatment of Yang syndromes. However, although Yin and Yang differ, the pathogenic factors (Toxic Qi) are not vastly different.
I now establish a formula to universally treat all types of carbuncles and sores regardless of Yin or Yang, which proves miraculous. The dosage for Yang syndromes should be reduced, while the number of ingredients for Yin syndromes should be increased. The formula is named "Yin Yang Tong Zhi Dan" (Yin-Yang Universal Treatment Pill). For Yin syndromes, double the amount of each herb and add one qian of Fuzi (Prepared Aconite Root). Do not arbitrarily add other herbs. The efficacy of this formula lies in Jinyinhua (Honeysuckle Flower), as this herb is a marvel for nourishing Yin and a holy medicine for dispersing pathogens and detoxifying. However, without large doses, the power is weak and the effect shallow; therefore, I use up to three liang.
Why is it suitable for Yang syndromes? Because nourishing Yin assists the insufficiency of Yang Qi. Yang is born from Yin, which holds profound utility. For Yin syndromes, it is especially appropriate; doubling the dose makes the power strong and the Qi focused. Adding Fuzi (Prepared Aconite Root) allows it to penetrate the meridians, entering every channel, and guiding herbs like Danggui (Angelica Sinensis Root) and Gancao (Licorice Root) to work together, making success easier to achieve. If people in the world do not heed my words and delay treatment due to inertia, Yin syndromes will inevitably become complicated/ruined syndromes, and Yang syndromes will transform into Yin syndromes, becoming incurable. This is truly pitiable.
