傅廉该观察清河时，其弟南安，寄来慎修（修园又号慎修）医书两卷、《东皋四书》文八卷，披阅不倦。题句云∶“东
皋制艺慎修医书，万顷汪洋孰望涯？”辛酉，余到直候补，叨识于牡牝元黄之外，此一时之盛事也，亦彼时之仅事也。
日者奉委赴热河，禀辞甫出，又传入署。曰∶雅着数种，俱经抄录，详加评点，但集中阙妇人阴挺一症，此症北方最多，
亦最除逆而难治，必不可阙。若到热河办公，公余当续补之。余答以近日医过两人获效之故，差次繁冗之中，尚恐立论
弗详，不如即于寓中，走笔书之。书成呈阅，一阅一击节。又问曰∶闻二十年前患此者少，自此地种产甘薯，妇人食之，
多生此疮，盖以疮形与甘薯相仿也。余曰∶此一想当然语，其实不然。甘薯始自闽省，俗名地瓜，性同山药，而甘味过
之。闽自福清以南及漳、泉二府滨海外，以此作饭，终身不生他病。《本草从新》谓其∶“补脾胃，驱湿热，养气血，长
肌肉”。海滨人多寿，皆食此物之故。《金薯谱》极赞其功。闽人治下痢，以白蜜同煎，食之甚效；妇人患赤白带，用此
法亦效；可知其利湿热之功尤巨也。鄙意以甘薯堪为阴挺证之专药。盖以阴挺之本，不离于湿，而此为探本之治；阴挺
之形突出如瓜，而此为象形之治。患此者，令其如法服药敷药之外，又以此物代饭，其效当必更速。观察曰∶善！请附
于前着之后，以补千古之阙，并折一时之疑，洵大方便之一事。
傅廉该观察在担任清河知县时，他的弟弟南安，寄来了慎修（即吴谦，号慎修）的医书两卷、《东皋四书》文章八卷，我翻阅起来不知疲倦。题诗写道：“东皋制艺慎修医书，万顷汪洋孰望涯？”辛酉年，我来到直隶候补任职，有幸在牡牝元黄（指阴阳或男女之理，此处借指高深医学理论之外）的境界中结识了他，这是当时的一件盛事，也是彼时少有的事情。
有一天，我奉命前往热河，刚禀告辞行出来，又被传回署衙。他说：“你雅致的著作几种，我都已经抄录下来，详细加以评点，但集中缺少‘妇人阴挺’这一病症，此症在北方最多，也是最逆乱难治的，绝对不能缺失。如果你到热河办公，公事之余应当续补它。”我回答说：“近日医治过两个人获得疗效的缘故，是在差事繁杂冗乱之中，还担心立论不够详尽，不如就在寓所中，挥笔写成。书写完成后呈给您审阅，您看后连连击节赞赏。”又问道：“听说二十年前患此病的人很少，自从此地种植并产出甘薯后，妇女食用它，多生此疮，大概是因为疮的形状与甘薯相仿吧。”我说：“这是一种想当然的说法，其实并非如此。甘薯最初来自福建省，俗称地瓜，药性同山药相似，而甘甜味道胜过它。福建从福清以南及漳州、泉州两府沿海地区，以此作饭吃，终身不生其他疾病。《本草从新》说它：‘补脾胃，驱湿热，养气血，长肌肉’。海边人长寿，都是吃这种物的缘故。《金薯谱》极力称赞它的功效。福建人治疗下痢，用白蜜同煎，食用非常有效；妇女患赤白带下，用这种方法也有效；可知它利湿热的功效尤其巨大。我的意见认为甘薯可以作为阴挺证的专药。因为阴挺的根本原因，离不开湿邪，而甘薯能探本求源地治疗；阴挺的形态突出如瓜，而甘薯是象形对应治疗。患此病的人，让他们依法服药敷药之外，又用此物代替米饭食用，疗效应当必定更快。观察说：‘好！请附在前著之后，以补充千古的缺失，并折服一时的疑惑，这确实是一件大方便的事。’”
When Fu Lian-gai, the Inspector, served as the Magistrate of Qinghe, his younger brother Nan'an sent him two volumes of medical books by Shenxiu (Wu Qian, courtesy name Shuxiu) and eight volumes of essays from *Donggao Six Books*, which he read with unflagging interest. He inscribed a poem: "The essays of Donggao and the medical books of Shenxiu are like vast waters; who can fathom their depths?" In the Xinyou year, I arrived in Zhili to await appointment, and had the honor of meeting him beyond the realms of Yin-Yang and male-female distinctions; this was a grand event of that time, and also a rare occurrence.
One day, having been commissioned to go to Rehe, I had just reported my departure when I was summoned back to the yamen. He said, "Your elegant works have been copied and carefully annotated, but your collection lacks the syndrome of 'uterine prolapse in women' (Furen Yinting). This syndrome is most common in the North, yet it is also among the most difficult and adverse to treat; it cannot be omitted. When you arrive at Rehe for official duties, please supplement it during your spare time." I replied, "The reason for the recent efficacy in treating two patients lies in the fact that amidst complex and tedious official tasks, I fear my theoretical exposition may not be detailed enough. It would be better if I were to write it down immediately in my residence." After completing the manuscript and presenting it for review, he read it and applauded repeatedly. He then asked, "I heard that twenty years ago, few people suffered from this disease. Since sweet potatoes began to be cultivated and produced here, many women who eat them develop this sore, presumably because the shape of the sore resembles that of a sweet potato." I said, "This is a presumptuous assumption, and actually incorrect. Sweet potatoes originated in Fujian Province, commonly known as 'Di Gua'. Their nature is similar to Chinese Yam (*Dioscorea opposita*), but their sweetness exceeds it. In the coastal areas south of Fuqing and in Zhangzhou and Quanzhou Prefectures of Fujian, people consume it as staple food and rarely suffer from other diseases. *Bencao Congxin* states that it: 'Tonifies the Spleen and Stomach, expels damp-heat, nourishes Qi and Blood, and promotes muscle growth.' The longevity of people along the coast is attributed to consuming this food. *Jinshu Pu* highly praises its merits. Fujianese people treat dysentery by decocting it with white honey, which is very effective; women suffering from leukorrhea (red and white discharge) also find this method effective; thus, its ability to promote the drainage of damp-heat is particularly significant. My opinion is that sweet potatoes can serve as a specific medicine for uterine prolapse. The root cause of uterine prolapse is inseparable from Dampness, and this food treats the root; the protruding shape of uterine prolapse resembles a melon or gourd, and this food corresponds by form. For patients suffering from this, besides taking medication and applying external treatments according to standard methods, using this food as a rice substitute should yield even faster results." The Inspector said, "Excellent! Please append this to your previous works to fill a千古 (ancient/long-standing) gap and resolve contemporary doubts; this is indeed a great convenience."
