Subjects : We tried to analysis dermatosurgical prescriptions including 477 WonBang(元方) prescriptions for SangJungHaTong(上中下統) introduced by HwangDoYeon(黃道淵). Methods : Prescriptions in BangYakHapPyun(方藥合編) is generally categorized into SangTong(上統), JungTong(中統), HaTong(下統) which are called PoJe(補劑), HwaJe(和劑), KongJe(功劑) respectively. This study classified and analyzed major diseases and symptoms appeared in dermatosurgical prescription and composition of medicine, as well as in BangYakHapPyun(方藥合編). Results and conclusions : The results of examining dermatosurgical prescriptions in WonBang(元方) of SangJungHaTong(上中下統) in BangYakHapPyun(方藥合編) are as follows; 1. The proportion of dematosurgical prescriptions was SangTong(上統) $\frac{10}{126}$(7.9$\%$). JungTong(中統) $\frac{22}{181}$(12.1$\%$), and HaTong(下統) $\frac{16}{163}$(9.8$\%$), which means that JungTong(中統)(HwaJe 和劑) takes up relatively the largest portion. 2. As for SangTong(上統), upper level herbs used in medicine are Glycyrrhiza uralensis(甘草), Paeonia japonica(白芍藥), Angelica gigas(當歸). Astragalus membranaceus(황기). Ginseng(人蔘), Poria cocos(복령), Atractylodis macrocephalae rhizoma(白朮). Cinnamon(肉桂), Rehmaniniae radix preparat(熱地黃). And these herbs are the components of Sipjundaebo-tang(十全大補湯), one of the most well-known medicine for weak energy and blood(補氣血). 3. As for JungTong(中統), in addition to medicine for weak energy and blood. Ledebouriella seseloides(防風) that removes ill elements on skin surface and Pung(風) called "wind". Limonium tetragonum(桔梗) that eliminates discharges and sputum, Angelica dahurica(白芷) that removes discharge and suppress tumor are applied. Other herbs are Ostericum koreanum(羌活). Skullcap(황령),Schizonepeta tenuifolia(荊芥), Aurantii fructus(地殼), Cimicifuga heracleifolia(升麻), Bupleurum falcatum(柴胡), Lonicerae flos(金銀花). These herbs are more effective for wind-calming treatment. cooling down fever, clearing skin irritation, detoxication. removal of tumor and discharge than replenishing energy and blood. 4. As for HaTong(下統), Angelica gigas(當歸) and Ledebouriella seseloides(防風), the two major herbs for SangTong(上統) and JungTong(中統), are mostly used. In addition, Skullcap(黃芩), Gardenia jasminoides(梔子), Eisenia bicyclis(大黃) are other major components and their key efficacy is to lower fever and KongHa(功下). 5. Herbs applied for SangTong(上統), JungTong(中統), and HaTong(下統) in large quantity are Glycyrrhiza uralensis(甘草) that harmoniously combine different herbal elements and Poria cocos(복령) that discharges humidity and watery elements out of body, removes humid and hot elements, and strengthen gastrointestinal system. Based on this, it is inferred that prescriptions for this study focus largely on treatment of humid and hot elements. In the composition of this prescription, Angelica gigas(當歸), Paeonia japonica(白芍藥), and Cnidium officinale(川芎) are taking up relatively large proportion, which are basic herbs for Samul-tang(四物湯). Therefore, it is incurred here that the concept of "replenishing blood" bears importance in dermatosurgical treatment. 6. As for herb medicines used for more than two types of prescriptions of SangTong(上統), JungTong(中統), and HaTong(下統), most of them are simultaneously used for SangTong(上統) and JungTong(中統), or for JungTong(中統), and HaTong(下統) except for Atractylodis macrocephalae rhizoma(白朮) and Gleditsia sinensis(조각자). This finding implies that prescription or treatment that are simultaneously applied are replenishing and harmonizing, or harmonizing and attacking while replenishing and attacking never go together.
