观此症，陡有气自脐上冲至胸腔，集于左乳下跳动不休。夫
有气陡起于脐上冲者，此奇经八脉中冲脉发出之气也。冲脉之原，上隶于胃，而胃之大络虚里，贯膈络肺出
于左乳下为动脉。然无病者其动也微，故不觉其动也。乃因此冲气上冲犯胃，且循虚里之大络贯膈络肺，复出
于左乳下与动脉相并，以致动脉因之大动，人即自觉其动而不安矣。当用降冲、敛冲、镇冲、补冲之
药以治病源，则左乳下之动脉，自不觉其动矣。爰拟两方于下∶
生山药（八钱） 生牡蛎（八钱） 生赭石末（四钱） 生芡实（四钱）
清半夏（足四钱中有矾须用温水淘净晒干） 柏子仁（四钱炒捣不去油） 寸麦冬（三钱）
上药七味，磨取铁锈浓水煎药。
又方∶用净黑铅半斤，用铁勺屡次熔化之，取其屡次熔化所余之铅灰若干，研细过罗。再将熔化所余
之铅秤之，若余有四两，复用铁勺熔化之。化后，用硫黄细末两半，撒入勺中，急以铁铲炒拌之，铅经硫黄灼
炼，皆成红色，因炒拌结成砂子。晾冷、轧细，过罗，中有轧之成饼者，系未化透之铅，务皆去净。二药各
用一两，和以炒熟麦面为丸（不宜多掺，以仅可作成丸为度），如桐子大。每服六七丸或至十余丸（以服后觉药
力下行，不至下坠为度），用生山药末五六钱，煮作稀粥送下，一日再服。以上二方单用、同用皆可。
Observing this syndrome, there is a sudden rising of Qi from above the umbilicus to the chest cavity, gathering and beating incessantly below the left breast. This Qi that suddenly rises from above the umbilicus is the Qi emanating from the Chong Mai (Penetrating Vessel) among the Eight Extraordinary Vessels. The origin of the Chong Mai is superiorly affiliated with the Stomach, and the great collateral of the Stomach, Xuli (ST17), penetrates the diaphragm, connects with the Lung, and emerges below the left breast as an arterial pulse. However, in healthy individuals, its movement is subtle, so one does not perceive it. Now, due to the rebellious rising of Chong Qi invading the Stomach, and following the great collateral of Xuli to penetrate the diaphragm and connect with the Lung, it re-emerges below the left breast alongside the arterial pulse, causing the artery to beat vigorously. Consequently, the patient perceives the beating and feels uneasy. One should employ herbs that descend, astringe, anchor, and tonify the Chong Mai to treat the root cause; then, the beating of the artery below the left breast will naturally cease to be perceived. Therefore, two prescriptions are formulated below:
Raw Dioscoreae Rhizoma (Shanyao) (8 qian), Raw Oyster Shell (Muli) (8 qian), Raw Hematitum Powder (Zheishi) (4 qian), Raw Euryales Semen (Qianshi) (4 qian),
Processed Pinelliae Tuber (Banxia) (sufficient 4 qian, if containing alum, wash clean with warm water and dry), Biota Seed (Baiziren) (4 qian, stir-fried, crushed without removing oil), Ophiopogon Radix (Maidong) (3 qian).
Decoct the above seven herbs in concentrated rust water obtained by grinding iron.
Another prescription: Use half a jin of pure black lead. Melt it repeatedly using an iron spoon. Collect the residual lead ash from these repeated meltings, grind it finely, and sieve it. Weigh the remaining lead after melting; if four liang remain, melt it again using an iron spoon. After melting, sprinkle one and a half liang of fine sulfur powder into the spoon, and quickly stir-fry and mix with an iron spatula. The lead, subjected to roasting and refining by sulfur, turns red and forms granules due to stirring. Allow to cool, crush finely, and sieve. Any pieces that form cakes indicate unrefined lead; ensure they are completely removed. Mix one liang of each of the two prepared substances with stir-fried wheat flour to make pills (avoid adding too much flour, just enough to form pills), sized like wu-tong seeds. Take six or seven pills, or up to ten or more per dose (adjust until the patient feels the medicinal action descending without a sensation of sinking). Send down with a thin porridge made from five or six qian of raw Dioscoreae Rhizoma powder. Take twice daily. Either of the above two prescriptions may be used alone or together.
