止血后，此药补之。
大人参（二两，去芦）
上每服水二盏，枣五枚，煎一盏细呷之。服后熟睡一觉，后服诸药除根。
功建三才得令名，阴阳血脱可回生，人参二两五枚枣，服后方知气力宏。
潘按∶世之用参者，或以些少姑试之，或加他味以监制之，其权不重，力不专，人何赖
以生？
古人多用于大汗大下之后，及吐血、血崩、血晕诸症，惟咳嗽去之。
凡失血后，不免精气怯弱，神思散乱。前方虽有止血之功，而无补益之力。故有形者之
阴，
自注云∶宜熟睡一觉，使神安气和，则烦除而自静。盖人之精神由静而生，亦由静而复也。
奈何今之医者，遇吐血家，乃视参如毒耶！
陈修园按∶《神农本草经》云∶人参气味甘微寒无毒，主补五脏，安精神，定魂魄，止
惊悸
以五脏属阴也，精神不安，惊悸不止，目不明，心智不足，皆阴虚为亢阳所扰也。今五脏得
甘寒之助，则安之定之，止之明之，开之益之之效矣。曰邪气者，非指外邪而言，乃阴虚而
壮火食气，火即邪气也，今五脏得甘寒之助，则邪气除矣。细味经文，无一字言及温补回阳
，何后人信从宋元无稽之说，而反疑开天明道之圣经耶？此症用至二两，以失血之后，脏阴
太虚，阴虚则不能维阳，阳亦随脱，故用二两，任专力大，可以顷刻奏功。但人参虽有补虚
之功，而咳嗽者忌之。乘此大血甫止之际，咳嗽未作，急急饮之。若得熟睡一夜，则血从心

之品，未免囿于俗见。然人参补阴与地黄龟板之一于补阴者不同，按其字义，参者，参也，
其功与天地人并立为三，且能入肺，肺为一身之橐龠，谓为益气，却亦近道，程山龄谓贫

After hemostasis, this medicine is used for tonification.
Ginseng Radix et Rhizoma (Ren Shen) (2 liang, remove the rhizome head)
For each dose, use two cups of water and five dates. Decoct until one cup remains, and sip slowly. After taking the medicine, sleep soundly; thereafter, take other medicines to eradicate the root cause.
Its efficacy establishes it among the Three Powers (Heaven, Earth, Human), earning its renowned name; when Yin and Yang or blood collapse, it can restore life. With two liang of Ginseng Radix et Rhizoma (Ren Shen) and five dates, one will know after ingestion that Qi and strength are magnificent.
Pan’s Commentary: In contemporary practice, those who use Ginseng Radix et Rhizoma (Ren Shen) either try it in small amounts tentatively or add other herbs to restrain its action. Its authority is not heavy, and its force is not concentrated. How can people rely on it for survival?
Ancients mostly used it after profuse sweating or severe purgation, as well as in conditions such as hematemesis (vomiting blood), metrorrhagia (uterine bleeding), and syncope due to blood loss. It was contraindicated only in cases of cough.
Following any hemorrhage, there is inevitably a weakness of Essence and Qi, and a scattering of mental thoughts. Although the preceding formula has the effect of stopping bleeding, it lacks the power of tonification. Thus, the tangible Yin...
Self-annotation: It is advisable to sleep soundly, so that Spirit is calm and Qi is harmonious; then irritability will disappear and tranquility will return naturally. Generally, human Spirit arises from stillness and recovers through stillness.
Why do modern physicians, upon encountering patients with hematemesis, regard Ginseng Radix et Rhizoma (Ren Shen) as poison!
Chen Xiuyuan’s Commentary: The *Shennong Bencao Jing* states: "Ginseng Radix et Rhizoma (Ren Shen) has a sweet, slightly cold taste and is non-toxic. It primarily tonifies the Five Zang organs, calms the Spirit, stabilizes the Hun and Po, and stops palpitations."
Since the Five Zang organs belong to Yin, an unsettled Spirit, unceasing palpitations, blurred vision, and insufficient mental capacity are all caused by Yin deficiency being disturbed by hyperactive Yang. Now, with the assistance of sweet-cold properties, the Five Zang organs achieve the effects of calming, stabilizing, stopping, clarifying, opening, and benefiting them. The term "pathogenic factor" mentioned does not refer to external pathogens, but rather to the fact that Yin deficiency leads to vigorous fire consuming Qi; this fire is the pathogenic factor. Now, with the assistance of sweet-cold properties, the pathogenic factors are eliminated. Carefully savoring the classic text, not a single word mentions warming and tonifying to restore Yang. Why do later generations believe in the baseless theories of the Song and Yuan dynasties and instead doubt the sacred classics that opened heaven and illuminated the Way? This condition requires up to two liang of Ginseng Radix et Rhizoma (Ren Shen) because after massive blood loss, the Zang Yin is extremely deficient. When Yin is deficient, it cannot sustain Yang, and Yang also collapses outwardly. Therefore, two liang are used, possessing concentrated authority and great power, capable of achieving results instantly. However, although Ginseng Radix et Rhizoma (Ren Shen) has the function of tonifying deficiency, it is contraindicated in coughs. Take advantage of the moment just after major bleeding has stopped, before coughing begins, and drink it urgently. If one sleeps soundly for a night, blood will be generated from the Heart, abundant and unstoppable. Even if liters or dou of blood were lost, replenishing it within a week would leave surplus. If awakened before sleep is sufficient, blood generation will cease. If taken only one or two days after bleeding stops, it will be not only ineffective but harmful. Zhou’s old commentary is also outstanding, but regarding Ginseng Radix et Rhizoma (Ren Shen) merely as a Qi-tonifying herb is somewhat limited by common views. However, Ginseng Radix et Rhizoma (Ren Shen)’s ability to tonify Yin differs from Rehmanniae Radix (Di Huang) and Testudinis Carapax et Plastrum (Gui Ban), which focus solely on tonifying Yin. Etymologically, "Shen" implies participation; its efficacy stands alongside Heaven and Earth and Humanity as the Three Powers. Furthermore, it enters the Lung meridian. The Lung is the bellows of the body. To say it benefits Qi is indeed close to the truth. Cheng Shanling said that for the poor...
