水臌、气臌之外,又有所谓血臌者,其证较水臌、气臌尤为难治。然其证甚稀少,医者或临证数十年不
一遇,即或遇之,亦止认为水臌、气臌,而不知为血臌。是以方书鲜有论此证者,诚以此证之肿胀形状,与
水臌、气臌几无以辨,所可辨者,其周身之回血管紫纹外现耳。
血臌之由,多因努力过甚,激动气血,或因暴怒动气,血随
气升,以致血不归经,而又未即吐出泻出,遂留于脏腑,阻塞经络,周身之气化因之不通,三焦之水饮因
之不行,所以血臌之证初起,多兼水与气也。迨至瘀血渐积渐满,周身之血管皆为瘀血充塞,其回血管
肤浅易见,遂呈紫色,且由呈紫色之处,而细纹旁达,初则两三处,浸至遍身皆是紫纹。若于回血
管紫色初见时,其身体犹可支持者,宜先用《金匮》下瘀血汤加野台参数钱下之。其腹中之瘀血下后,可再
用药消其血管中之瘀血,而辅以利水理气之品。程功一月,庶可奏效。若至遍身回血管多现紫色,病候至此,
其身体必羸弱已甚,即投以下瘀血汤,恐瘀血下后转不能支持,可用拙拟化瘀通经散,再酌加三七末服之,
或用利水理气之药煎汤送服,久之亦可奏效。若腹中瘀血已下,而周身之紫纹未消者,可用丹参、三七末各一
钱,再用山楂四钱煎汤,冲红糖水送服,日两次,久自能消。
《金匮》下瘀血汤∶大黄三两(当为今之九钱),桃仁三十个, 虫二十枚去足熬(炒也)。上三味末
之,炼蜜和为四丸,以酒一升(约四两强)煮一丸,取八合顿服之,瘀血下如豚肝。按∶此方必先为丸而后
作汤服者,是不但服药汁,实兼服药渣也。盖如此服法,能使药之力缓而且大,其腹中瘀久之血,可一服尽
下。有用此方者,必按此服法方效。又杏仁之皮有毒,桃仁之皮无毒,其皮色红,活血之力尤大,此方桃仁,
似宜带皮生用。然果用带皮生桃仁时,须审辨其确为桃仁,勿令其以带皮之杏仁误充。
究之,病血臌者,其身体犹稍壮实,如法服药,原可治愈。若至身体羸弱者,即能将其瘀治净,而
转有危险,此又不可不知。临证时务将此事言明,若病家恳求,再为治之未晚也。
除了水臌(以腹水积聚为主要表现的鼓胀病)和气臌(以气机阻滞、腹部胀满为主要表现的鼓胀病)之外,还有一种被称为血臌的病证,其病情比水臌和气臌更加难以治疗。然而这种病证非常稀少,医生即使行医数十年也可能一次都遇不到;即便遇到,也往往将其误认为是水臌或气臌,而不知道这是血臌。因此,方书医籍中很少有关于此证的论述,确实是因为这种病证的肿胀形态与水臌、气臌几乎无法区分,唯一可以辨别的地方,在于患者周身静脉血管出现紫色的纹路并显露于体表。
血臌的成因,多是因为过度用力,导致气血激荡;或者因为突然发怒导致气机上逆,血液随气上升,致使血液不能正常循行于经脉之中,而又没有立即通过呕吐或腹泻排出体外,于是血液滞留于脏腑之间,阻塞经络,使得周身的气化功能因此不通畅,三焦的水液代谢也因此无法正常进行。所以,血臌在初起阶段,往往兼有水湿和气滞的症状。等到瘀血逐渐积聚充盈,全身的血管都被瘀血堵塞,位于皮下的静脉血管变得浅显易见,呈现出紫色,并且从呈现紫色的部位向周围延伸出细小的纹路,起初只有两三处,随后逐渐蔓延至全身都是紫纹。如果在静脉血管刚出现紫色时,患者的身体尚能支撑,适宜先用《金匮要略》中的下瘀血汤加入野台参(即党参)数钱来攻下瘀血。待腹中的瘀血排出后,可以再用药消除血管中的瘀血,并辅以利水和理气的药物。坚持治疗一个月,或许可以见效。如果发展到全身静脉血管多处呈现紫色,病情至此,患者的身体必定已经极度虚弱,此时即使投用下瘀血汤,恐怕瘀血排出后患者反而无法支撑,可以使用我拟定的化瘀通经散,再酌情加入三七粉服用,或者用利水理气的药物煎汤送服,久而久之也能见效。如果腹中的瘀血已经排出,但全身的紫纹尚未消退,可以用丹参、三七粉各一钱,再用山楂四钱煎汤,冲红糖水送服,每天两次,时间久了自然能消散。
《金匮要略》中的下瘀血汤:大黄三两(相当于现在的九钱),桃仁三十个,䗪虫二十枚(去足后熬制/炒制)。以上三味药研成粉末,用炼蜜调和制成四丸,用酒一升(约四两多一点)煮一丸,取八合一次性服用,排出的瘀血像猪肝一样。按语:这个方子必须先做成丸剂然后作为汤药服用,这不仅仅是喝药汁,实际上是连同药渣一起服用。因为这样的服用方法,能使药力缓和且作用强大,腹中久留的瘀血可以一服药就全部排出。使用此方的人,必须按照这种服用方法才有效。另外,杏仁的皮有毒,桃仁的皮无毒,其皮色红,活血的力量尤其大,此方中的桃仁,似乎适宜带皮生用。但如果确实使用带皮生桃仁时,必须仔细辨别确认其为桃仁,不要让它被带皮的杏仁误充。
总之,患有血臌的病人,如果身体还稍微壮实,按照上述方法服药,原本是可以治愈的。如果到了身体虚弱的程度,即使能将瘀血彻底清除,也会有危险,这一点又不可不知道。临证时必须将此事向患者说明清楚,如果病人恳切请求治疗,再进行治疗也不迟。
In addition to Shuigu (Ascites with fluid accumulation) and Qigu (Abdominal distension due to Qi stagnation), there is another condition known as Xuegu (Abdominal distension due to blood stasis), which is even more difficult to treat than Shuigu or Qigu. However, this condition is very rare; a physician might practice for decades without encountering it once. Even if encountered, it is often mistaken for Shuigu or Qigu, and the practitioner may not realize it is Xuegu. Therefore, medical texts rarely discuss this condition, truly because the swelling morphology of this condition is almost indistinguishable from that of Shuigu and Qigu. The only distinguishable feature is the appearance of purple reticular patterns on the superficial veins throughout the body.
The etiology of Xuegu is mostly due to excessive physical exertion, which agitates Qi and Blood, or due to sudden anger causing Qi to rise upward, leading Blood to ascend with Qi. This results in Blood failing to return to its proper meridians. If this Blood is not immediately expelled through vomiting or diarrhea, it remains stagnant in the Zang-Fu organs, blocking the meridians. Consequently, the Qi transformation throughout the body becomes obstructed, and the water metabolism of the Sanjiao (Triple Burner) fails to function normally. Thus, at the onset of Xuegu, symptoms of Water retention and Qi stagnation are often present. As the blood stasis gradually accumulates and fills up, the blood vessels throughout the body become blocked by stasis. The superficial veins become visible and turn purple, with fine reticular patterns extending outward from these purple areas. Initially, there may be only two or three such areas, but eventually, purple reticles cover the entire body. If, when the purple color first appears in the superficial veins, the patient's constitution is still supportive, it is appropriate to first use Xia Yuxue Tang (Downward-Purging Decoction for Blood Stasis) from the *Jingui Yaolue* (*Essential Prescriptions of the Golden Cabinet*), added with Ye Taishen (Codonopsis Radix, Dangshen) for a few qian, to purge the stasis. After the abdominal stasis is purged, medication can be used again to resolve the stasis within the blood vessels, supplemented by herbs that promote diuresis and regulate Qi. Persisting in treatment for one month may yield results. If the condition progresses to the point where multiple superficial veins throughout the body show purple discoloration, the patient's body must have become extremely emaciated and weak. At this stage, even administering Xia Yuxue Tang might risk the patient's inability to withstand the purgation after the stasis is expelled. In such cases, one may use my formulated Huayu Tongjing San (Blood-Resolving and Meridian-Unblocking Powder), optionally mixed with Sanqi powder (Notoginseng Radix et Rhizoma), or taken with a decoction of herbs that promote diuresis and regulate Qi. Over time, this too can be effective. If the abdominal stasis has been purged but the purple reticles on the body have not yet disappeared, one can use Dan Shen powder (Salvia Miltiorrhiza Radix et Rhizoma) and Sanqi powder, each 1 qian, along with a decoction of Shan Zha (Crataegus Pinnatifida Fructus) 4 qian, taken with brown sugar water, twice daily. With prolonged use, they will naturally dissipate.
Xia Yuxue Tang (Downward-Purging Decoction for Blood Stasis) from *Jingui Yaolue*: Dahuang (Rhei Radix et Rhizoma) 3 liang (equivalent to 9 qian today), Taoren (Persicae Semen) 30 pieces, E chong (Eupolyphaga seu Steleophaga, ground beetle) 20 pieces (feet removed and roasted/fried). The above three ingredients are powdered, mixed with refined honey to form four pills. One pill is boiled in 1 sheng of wine (approximately 4+ liang), yielding 8 ge, taken in one dose. The discharged stasis resembles pig liver. Note: This formula must be prepared as pills and then administered as a decoction. This method involves consuming not only the liquid but also the dregs. Such administration ensures that the medicinal power is both gentle and potent, allowing long-standing abdominal stasis to be completely purged with a single dose. Those using this formula must adhere to this method for efficacy. Furthermore, the skin of Xingren (Armeniacae Semen Amarum, bitter apricot seed) is toxic, whereas the skin of Taoren is non-toxic. Its red skin possesses particularly strong blood-invigorating properties. Thus, the Taoren in this formula seems suitable for raw use with the skin intact. However, if raw Taoren with skin is indeed used, careful identification is required to ensure it is genuine Taoren and not mistakenly substituted with Xingren with skin.
Ultimately, patients with Xuegu whose constitutions are still relatively robust can be cured if treated according to the aforementioned methods. If the patient has become emaciated and weak, even if the stasis is thoroughly cleared, there remains a risk of danger. This is an important point to recognize. During clinical practice, this matter must be clearly explained to the patient. If the patient earnestly requests treatment, it is not too late to proceed.
