既不信余药，请余何为？”病家不得已，购药一剂，俾煎汤两盅，作两次服下。而热势益炽，病家疑药不对证。
余曰∶“此非药不对证，乃药轻不胜病耳。”遂俾将两剂并作一剂，煎汤一大碗，徐徐温饮下。移时汗出便通，
病若失。
（附∶人参形状考）
人参之种类不一，古所用之人参，方书皆谓出于上党，即今之党参是也。考《神农本草经》载，人参味甘，
未尝言苦，今党参味
甘，辽人参则甘而微苦，古之人参其为今之党参无疑也。特是，党参之性，虽不如辽人参之热，而其性实温而
不凉，乃因《神农本草经》谓其微寒，后世之笃信《神农本草经》者，亦多以人参之性果然微寒，即释古方之
用人参者，亦本微寒之意以为诠解，其用意可谓尊经矣。然古之笃信《神农本草经》而尊奉之者莫如陶弘景，
观其所着《名医别录》，以补《神农本草经》所未备，谓人参能疗肠胃中冷，已不遵《神农本草经》以人参为
微寒可知。因此，疑年湮代远，古经字句或有差讹，吾人生今之世，当实事求是，与古为新。今试即党参实验
之，若与玄参等分并用，可使药性无凉热，即此可以测其热力矣（此即台党参而言，若潞党参其热稍差）。然
辽东亦有此参，与辽人参之种类迥别，为其形状性味与党参无异，故药行名之为东党参，其功效亦与党参同。
至于辽人参，其补力、热力皆倍于党参，而其性大约与党参相似，东人谓过服之可使脑有充血之病，其性补而
上升可知。方书谓人参，不但补气，若以补血药辅之亦善补血。愚则谓，若辅以凉润之药即能气血双补，盖平
其热性不使耗阴，气盛自能生血也。至《神农本草经》谓其主补五脏、安精神、定魂魄、止惊悸、除邪气、明
目、开心、益智，无非因气血充足，脏腑官骸各得其养，自有种种诸效也。
既然您不相信我开的药，那还要请我来做什么呢？”病人家属无可奈何，买回一剂药，让我煎成两碗汤，分两次服用。然而病情发热更加严重，病人家属怀疑药不对症。
我说：“这不是药不对症，而是药力太轻，压不住病邪。”于是让他们将两剂药合并为一剂，煎成一大碗汤，慢慢温热着喝下去。过了一会儿，汗出大便通畅，病就好了。
（附：关于人参形态的考证）
人参的种类不一，古代所用的人参，医方书籍都说出自上党，就是现在的党参。考证《神农本草经》记载，人参味甘，从未说过味苦，现在党参味甘，辽人参则甘而微苦，古代的人参毫无疑问就是现在的党参。只是党参的药性，虽然不如辽人参之热，但其性质确实是温而不凉。这是因为《神农本草经》说它微寒，后世笃信《神农本草经》的人，也多认为人参的性质果然微寒，即使解释古方中使用人参的用意，也是基于微寒的意思来诠释，这种用意可以说是尊崇经典了。然而古代笃信《神农本草经》并尊奉它的人没有比陶弘景更多的了，看他所著的《名医别录》，用来补充《神农本草经》所未完备的内容，说人参能治疗肠胃中的冷证，这就不遵循《神农本草经》以人参为微寒的说法了，由此可知。因此，怀疑年代久远，古经的字句或许有差错讹误，我们生活在当今时代，应当实事求是，与古人创新。现在试着用党参做实验，如果与玄参等量并用，可以使药性不凉不热，由此可以推测其热力了（这里说的是台党参，如果是潞党参，其热力稍差）。然而辽东也有这种参，与辽人参的种类截然不同，因为它的形状、性味与党参无异，所以药材行里叫它东党参，其功效也与党参相同。至于辽人参，其补益之力、热力都加倍于党参，而其性质大约与党参相似，日本人说过量服用会导致脑部充血疾病，可见其性质是补益且上升的。医方书籍说人参，不但补气，如果用补血药辅助它也能善于补血。我却认为，如果用凉润的药物辅助它就能气血双补，大概是因为平抑了其热性，不使阴液耗损，气盛自然能生血。至于《神农本草经》说它主要补益五脏、安定精神、定魂魄、止惊悸、除邪气、明目、开心窍、益智，无非是因为气血充足，脏腑肢体各得其滋养，自然会有种种功效。
Since you do not believe in my herbs, why did you ask me to come?" Reluctantly, the patient's family purchased one dose of medicine and instructed me to decoct it into two bowls of soup, to be taken in two divided doses. However, the fever intensified, leading the family to suspect that the prescription was inappropriate for the syndrome.
I said, "This is not due to an inappropriate prescription, but rather because the dosage is too light to overcome the disease." I then instructed them to combine two doses into one, decoct it into a large bowl of soup, and drink it slowly while warm. After some time, sweating occurred and bowel movements were unblocked, and the illness seemed to vanish.
(Attachment: An Examination of the Morphology of Ren Shen)
There are various types of Ren Shen (Ginseng Radix et Rhizoma). The Ren Shen used in ancient times, as stated in medical formularies, originated from Shangdang, which corresponds to the current Dang Shen (Codonopsis Radix). According to an examination of the *Shennong Bencao Jing* (Divine Farmer's Materia Medica), Ren Shen has a sweet taste, and bitterness is never mentioned. Currently, Dang Shen tastes sweet, whereas Liaoren Shen (Liaoning Ginseng) is sweet with a slight bitterness. Therefore, the ancient Ren Shen was undoubtedly what we now call Dang Shen. However, although the nature of Dang Shen is not as hot as that of Liaoren Shen, its nature is truly warm and not cool. This misconception arises because the *Shennong Bencao Jing* describes it as slightly cold. Later generations who firmly believed in this text assumed that Ren Shen is indeed slightly cold. Even when interpreting the use of Ren Shen in ancient prescriptions, they based their explanations on the notion of slight coldness, showing great respect for the classic. Nevertheless, no one in ancient times believed in and revered the *Shennong Bencao Jing* more than Tao Hongjing. In his work *Mingyi Bielu* (Record of Famous Physicians), written to supplement the *Shennong Bencao Jing*, he stated that Ren Shen can treat coldness in the intestines and stomach. This indicates that he did not follow the *Shennong Bencao Jing*'s classification of Ren Shen as slightly cold. Thus, one may suspect that due to the passage of time, there might be errors or corruptions in the characters and sentences of ancient classics. Living in the present era, we should seek truth from facts and innovate upon the past. Let us experiment with Dang Shen: if used in equal proportions with Xuan Shen (Scrophulariae Radix), it neutralizes the cooling or heating properties, allowing us to infer its warming power (this refers to Tai Dang Shen; Lu Dang Shen has slightly less warming power). Furthermore, there is a type of ginseng in Liaodong that is distinct from Liaoren Shen in species. Because its morphology and taste are identical to Dang Shen, the herbal trade calls it Dong Dang Shen (Eastern Codonopsis), and its efficacy is also the same as Dang Shen. As for Liaoren Shen, its tonifying power and warming heat are double those of Dang Shen, and its nature is roughly similar to Dang Shen. Japanese sources state that excessive consumption can cause cerebral congestion, indicating that its nature is tonifying and ascending. Medical formularies state that Ren Shen not only tonifies Qi, but when assisted by blood-tonifying herbs, it is also effective in tonifying Blood. I, however, believe that when assisted by cooling and moistening herbs, it can tonify both Qi and Blood. This is because by moderating its heat, Yin fluids are not consumed, and abundant Qi naturally generates Blood. Regarding the statement in the *Shennong Bencao Jing* that it primarily tonifies the five Zang organs, calms the spirit, stabilizes the Hun and Po, stops palpitations, eliminates pathogenic factors, brightens the eyes, opens the mind, and enhances intelligence, these effects are all due to sufficient Qi and Blood nourishing the Zang organs and limbs, thereby producing various benefits.
