In order to determine the effect of Oryeongsan reputed to have diuretic action since Han Dynasty and possible synergetic action of Dianthi Semen, Polygonum avicularis Herba, Kochiae Fructus and Akebiae Lignum, herbs with similar reputation, when added to the above prescription, their decoction powders were solved into distilled water and injected into rabbits through the ear vein. Upon the treatment, the excretion of sodium, potassium and chloride ion together with urine volume was kinetically determined. At the same time the clearance of plasma creatinine and sodium ion was determined and the following results were obtained. Every experimental group demonstrated diuretic action, though feable, of relatively long duration. The diuretic mechanism in the case of Oryeongsan made up by mixing the seperate extracts of individual components and Oryeongsan(A) plus Dianthi Semen was found to be inhibitory effect of renal tubular reabsorption in contrast to the case of Oryeongsan(A) plus Polygonum avicularis Herba, Kochiae Fructus or Akebiae Lignum in which case the diuretic mechanism was found to be glomerular vascular dilatation. The urinary excretion of potassium ion was increased in the case of Oryeongsan(A) plus Dianthi Semen, Kochiae Fructus of Akebiae Lignum whereas in the other cases no similar change was registered. The diuretic action was most remarkable in the case of Oryeongsan(A) plus Polygonum avicularis Herba followed by Oryeongsan(A) plus Kochiae Fructus, Oryeongsan(A) plus Dianthi Semen, extract mixture of individual component of Oryeongsan, Oryeongsan(A) and Oryeongsan(A) plus Akebiae Lignum decreasing order. The duration of diuretic action was found to be 90 minutes in the case of Oryeongsan and mixture of individual component of Oryeongsan, and 60 minutes in the case of Oryeongsan(A) plus Dianthi Semen, Kochiae Fructus or Akebiae Lignum in contrast to the case of Oryeongsan(A) plus Polygonum avicularis Herba which lasted up to 120 minutes.

In "Sanghanlon(傷寒論)", there are several articles to explain about Oryeongsan's syndrome. Most important articles of them are No. 72 and No. 75. Oryeongsan is explained by many doctors as a prescription to control exterior and interior, because they considered that symptoms of 72 and 75 articles were caused by exterior and interior's syndrome. Accordingly, they explained that RAMULUS CINNAMOMI(桂枝) and warm water remove exterior pathogens, and PORIA(茯笭) and others remove interior fluid retention. But considering the origin of a fluid retention, RAMULUS CINNAMOMI's effects are rather activating Yang(通陽) and warming Yang(溫陽) than removing exterior pathogens. The fluid retention is cauesd by insufficiency of Yang energy, because body fluid's spreading depends on Ynag energy. RAMULUS CINNAMOMI's effects of activating Yang and warming Yang improve the fluid retention and spread body fluid to the whole body. Some doctors use CORTEX CINNAMOMI(肉桂) instead of RAMULUS CINNAMOMI, because CORTEX CINNAMOMI's effects of activating Yang and warming Yang are better than RAMULUS CINNAMOMI's. There are many opinions about what is the main symptom of Oryeongsan's syndrome, but the difficulty in urination is understood by most doctors as the main symptom of Oryeongsan's syndrome. From the viewpoint of that, they understand that Oryeongsan's main effect is the induce diuresis. But the induce diuresis does not only mean a urination. The induce diuresis must be understood as the removing fluid retention by sweat and urine through the spreading body fluid.

Objectives : The purpose of this study was to report two cases which suggest Oryeongsan as a pharmacological treatement option for cancer-induced secondary lymphedema. Methods : The cases were two female patients with peripheral edema. The first was diagnosed with cervical cancer with paraaortic lymph node metastasis and suffered from bilateral edema of the lower extremities. The second was a breast cancer patient with right arm lymphedema, which was aggravated after a weekly regimen of chemotherapy. Oryeongsan was orally administered for 3-4 days to both patients. Results : The symptoms in lower extremities and body weight of the cervical cancer patient decreased. The breast cancer patient did not lose body weight, but pain in upper extremities was reduced. Conclusions : Oryeongsan may potentially be an option for secondary lymphedemas, including cancer-induced lymphedema.

Oryeongsan (ORS), a formula composed of five herbal medicines, has long been used to treat impairments of the regulation of body fluid homeostasis. The purpose of this study was to determine the antihypertensive and renal protective effects of ORS in rats with hypertension. Spontaneously hypertensive rats (SHR) were divided into two groups with similar mean baseline systolic blood pressure (SBP). Then, 1 mL/kg of vehicle (distilled water) or 1.5, 3 g/kg of ORS extract were administered orally once a day for 4 weeks. SBP and diastolic blood pressure (DBP) were measured at weeks 1, 2, 3 and 4. At the end of the experiment, blood was collected, and heart were removed for histology. By the 2 weeks after initiation of treatment, the ORS treated group had significantly lower SBP than SHR rats. The ORS treatment significantly improved blood pressure and echocardiogram parameters compared to hypertensive rats. Additionally, the left ventricular (LV) remodeling and LV dysfunction were significantly improved in ORS treated group hypertensive rats. Furthermore, an increase in fibrotic area has been observed in SHR rats compared with Wistar-Kyoto rats (WKY). Furthermore, administration of ORS significantly attenuated cardiac fibrosis in hypertensive rats. Therefore, these findings suggest that ORS has a protective effect on heart failure by alleviating hypertensive heart disease and cardiovascular dysfunction in SHR.

Ureteral obstruction can be causes of renal dysfunction and renal injury at late period of kidney pathology. The purpose of this study was to determine the protective effects of Oryeongsan (ORS), Geumgwe-sinkihwan (GSH), and Jwagwieum (JGE) in rats with unilateral ureteral obstruction (UUO). The animal models were divided into five groups randomly at the age of 5 weeks; Control group: SD male rats (n=10), UUO group: SD male rats with UUO surgery (n=10), ORS group: SD male rats with UUO surgery + ORS 200 mg/kg/day (n=10), GSH group: SD male rats with UUO surgery + GSH 200 mg/kg/day (n=10), JGE group: SD male rats with UUO surgery + JGE 200 mg/kg/day (n=10). Treatment with ORS, GSH, and JGE significantly ameliorate creatinine clearance(Ccr). The present results also showed that ORS, GSH, and JGE improved the morphological aspects of renal tissues. These prescriptions also reduced the expression levels of cytokines such as TNF-α, IL-1β, and IL-6. In Kidney, UUO increased the expression levels of inflamasome markers such as NLRP3, ASC, and Caspase-1. However, ORS, GSH, and JGE suppressed these levele. Treatment with these prescriptions reduced kidney inflammation markers such as Neutrophil Gelatinase Associated Lipocalin (NGAL) and kidney injury molecule -1 (KIM-1). Therefore, these findings suggest that ORS, GSH, and JGE has a protective effect on renal injury by alleviating renal inflammation and improving renal function in rats with UUO.
