The decocting method of herbal medicines is various with a prescription or herbal medicine's characteristics. But it has common principles by which effective elements can be easily extracted with synergistic actions of herbs and which the therapeutic effect of a medicine is amplified. When decocting a herbal medicine, the volume of water is an important factor. Fire for decocting drugs and decocting time are also important factors. The excessive water and unproper decocting time and temperature can reduce the effect of the decoction. Besides a better decoction can be obtained by squeeze. According to herbal medicine's characteristics and prescription, there are herbs that should be treated after a specific method. For example, decoct first and decoct later. It also affects the therapeutic if a right taking method is not carried out. Methods of taking drugs include both the time and the method. We can confirm these decocting and taking methods in the ancient medical literatures of herbal medicine. This article deals with these things in detail.

This is a study on the methods of decocting prescriptions in SANGHANRON (傷寒論), and after this, numbers of results have been obtained. SANGHANRON was written by Chang-Ki (張機) in the 2nd century, so it reflexes the usage of prescriptions of previous age indirectly. And gave affects on the methods of decocting prescriptions to the oriental medicine doctors of next generation.Berore Han-DYnasty(漢代), there were not so many publications connected with Oriental Medicine. Besides, some books couldn't hand down to next generation due to the gap of time and space. As time goes by, letters in medical books changed little by little, so contents connected with decocting methods changed too. The effects of decoction and herb tea can be changed by the flexibility of methods of decocting medicines, so we have to decide what kinds of decocting methods should be taken and adapted to patients by the most effective way.In SANGHANRON, there are many kiny kinds of boiling methods, so DHAMG-Ki selected the most appropriate method considering deree and position of disease and condition of patient. But nowadays, due to inconvenient procedure of boiling and taking medicines, some methos are not in common in clinical medicin. So this study was started to look back upon the changes of decocting prescriptions and gave deffort to find out the propriety of variation of boiling prescriptions.The common method of decocting prescriptions in SANGHANRON is boiling down all the herbs at the same time. Except the commom method, there are some kinds of other methods - boiling down twice the prescription, boiling down some special herbs earlier of later than other herbs, complicated or special boiling methods of extract, etc. These kinds of decoting methods simplified as time pass by, but this expected therapeutic value. So we have to distinguish the methods -though complicated and troublesome- in clinical medicine to make perfection more perfect in treating patients, and further studies have to be followed to prove the propriety of these complicated methods.

Objectives : To broaden understanding of "Shanghanlun", this paper analyzes and interprets its Post-formula instructions(方後注文). Methods : From the contents of Post-formula instructions that follow formulas in "Shanghanlun", the effects, administration instructions, decocting methods are examined specifically. Based on annotators's interpretations, the author provides his understanding. Conclusions & Results : The treatment principle of sweat inducive formulas is 'to induce subtle sweating(微似汗)'. Meanwhile, in the case of Inner water and fluid retention(水飮內停), 'sweating(汗出)' is expressive of healing. Among the emetic formulas in the "Shanghanlun", the meaning of 'vomiting(得吐者)' in the descriptions of Zhizichitang(梔子豉湯), is that the stagnated heat in the chest area has been relieved, letting the Qi communicate upwards. In terms of formula administration, besides the usual 2~3 times a day method, there is '頓服法' for immediate effects; three times within six hours application method in cases where the exterior symptoms are extremely severe or the stagnation of exterior pathogen is severe; 6 times a day or continuous application day and night regardless of frequency. In terms of decocting methods, there is '再煎法' to have the formula's effects not be biased or too strong; the decocting method of Dahuanghuanglianxiexīntang where the formula is brewed momentarily in order to cool the immaterial pathogenic heat. Moreover, when there is disease in the chest, Dahuang is brewed first to soften its effects. When there is disease in the abdomen area, Dahuang is added later to quicken its effects. In the case of Guizhirenshentang, to maximize the effect of Guizhi, it was suggested that Guizhi is added later.

Two kinds of ginseng extracts were prepared and their brown color and radical scavenging activity were evaluated. The extract prepared by decoction after steaming exhibited deeper brown color and stronger radical scavenging activity than the extract prepared by decoction only. The difference in color and radical scavenging activity was greater in white ginseng than in fresh ginseng. Steaming white ginseng for 3 h was equivalent to 45 h of decoction in its brown color and radical scavenging activity. Consequently, we believe steaming process is better method than decoction to increase the biological activity of ginseng.

Eum Yang Kwak, the aerial part of Epimedium koreanum, is widely used as a folk medicine for stimulant in man, tonic, and hypotensive purpose. The plant contains icariin (a specific flavonoid), magnoflorine (an alkaloid) and tannin, but their contents are not known until now. In this paper, a quantitative analysis method for them was developed. Determination of icariin and magnoflorine was successfully achived by high performance liquid chromatography equipped with a UV detector in the ranges of $0.1{\sim}0.4\;mg$ and $0.002{\sim}0.1\;mg\;per\;ml$ sample, respectively. Extraction of the plant was carried out with water or 50% ethanol using different decocting temperatures and times. Icariin was well extracted either by water ($100^{\circ}C$, 3hr) or 50% ethanol ($85^{\circ}C$, 1hr), and its content in the plant was measured to be 0.94%. On the other hand, magnoflorine was fully extracted by 50% ethanol ($85^{\circ}C$, 1hr), and its content was determined to be 0.16%. Therefore, decoction of the medicinal plant with water at $100^{\circ}C$ for 3hr turned out to be recommendable for the best extraction.
