《素问》云∶人有所坠堕，恶血留内，腹中满胀，不得前后，先饮利药。此上伤厥阴
之脉，下伤少阴之络，刺足内踝之下，然骨之前，血脉出血。刺足跗上动脉，不已；刺
三毛上各一 ，见血则已，左刺右，右刺左。善悲惊不乐，刺如右方。（缪刺论） 《灵枢》云∶
有所堕坠，恶血留内，有所大怒，气上而不行下，积于胁下，则伤肝。又中风及有所击
仆，若醉入房，汗出当风，则伤脾。又头痛不可取于 者，有所击堕，恶血在内，若肉
伤，痛未已，可侧刺不可远取之也。（邪气脏腑及厥病篇）
东垣《医学发明》论曰∶夫从高坠下，恶血留于内，不分十二经络，医人俱作中风肝
经，留于胁下，以中风疗之。血者皆肝之所主，恶血必归于肝，不问何经之伤，必留于
胁下，盖肝主血故也，痛甚则必有自汗，但人人有汗出，皆属风证，诸风皆属于肝木，况
败血凝泣，逆其所属入于肝也，从高坠下，逆其上行之血气，非肝而何？非伤寒无汗。既
曰∶汗必自风化之也，故以破血行经药治之。

The *Suwen* states: When a person falls from a height, evil blood remains inside, causing abdominal fullness and distension, and inability to pass stool or urine. One should first drink purgative medicines. This injury damages the Jueyin meridian above and the Shaoyin collateral below. Acupuncture should be performed at the area below the medial malleolus of the foot, anterior to Ran Gu (BL64), to bleed the vessels. If needling the arterial pulse on the dorsum of the foot is ineffective, needle each of the three hairs on the big toe (near Yinbai SP1), one pricking per site, until bleeding occurs. Treat left-sided symptoms by needling the right side, and right-sided symptoms by needling the left. For symptoms of sadness, fright, and unhappiness, follow the same needling method. (From *Miao Ci Lun*)
The *Lingshu* states: Falling causes evil blood to remain inside. Great anger causes Qi to rise but not descend, accumulating under the hypochondrium, thereby injuring the Liver. Additionally, wind-stroke, being struck or fallen, or having intercourse while drunk with sweat exposed to wind, injures the Spleen. Regarding headache where acupuncture at a specific point is contraindicated due to being struck or fallen, with evil blood remaining inside, if muscle injury causes persistent pain, lateral needling should be used rather than distant points. (From *Xieqi Zangfu Bingxing Pian* and *Juebing Pian*)
Li Dongyuan discusses in *Yixue Faming*: When falling from a height, evil blood remains inside. Regardless of which of the twelve meridians is injured, physicians often treat it as a Wind-stroke affecting the Liver meridian, assuming blood accumulates under the hypochondrium and treating it as Wind-stroke. Blood is governed by the Liver; evil blood inevitably returns to the Liver. Regardless of the initial meridian injury, evil blood must accumulate under the hypochondrium because the Liver governs blood. Severe pain leads to spontaneous sweating. Since everyone sweats, these symptoms are attributed to Wind patterns, and all Wind patterns belong to Liver Wood. Moreover, congealed bad blood reverses its flow and enters the Liver. Falling from a height reverses the ascending Qi and Blood; who else but the Liver? This differs from Cold Damage where there is no sweating. Since it is stated that "sweat is transformed by Wind," therefore, blood-breaking and meridian-moving herbs are used for treatment.
