Treatment method: Based on the principles of fortifying the spleen and securing the kidneys acne laser treatment cost buy acnetane 40 mg cheap, warming and supplementing the life-gate skin care doctors orono order acnetane pills in toronto, containing the spring and reducing urination acne 5 purchase discount acnetane on line, all members of this study received the following Chinese medicinals: Huang Qi (Radix Astragali), 40g Dang Shen (Radix Codonopsitis), 20g Yi Zhi Ren (Fructus Alpiniae Oxyphyllae), 10g Fu Pen Zi (Fructus Rubi), 10g Sang Piao Xiao (Ootheca Mantidis), 10g One packet of these medicinals was decocted in water and administered per day. Study outcomes: Cure was defined as disappearance of both enuresis and frequent urination as well as all accompanying signs and symptoms. In addition, the child had a normal spirit and their appetite increased. The longest course of treatment was nine days and the shortest length of treatment was three days. In three cases, the enuresis returned but was cured when the treatment was resumed. Discussion: According to the Chinese authors, Huang Qi and Dang Shen with- in this formula supplement the center and boost the qi. Yi Zhi Ren, Fu Pen Zi, and Sang Piao Xiao all secure the kidney qi and Chinese Research on the Treatment of Pediatric Enuresis 95 warm the life-gate. If the kidney qi is full and the life-gate is exu- berant, then they are able to warm the latter heaven spleen. In gener- al, the medicinals which are warm in nature easily damage the flu- ids and humors, especially if there is frequent urination. Therefore, this formula should not be taken long-term but should be discontinued as soon as the dis- ease is cured for fear that it may eliminate the old disease but engender a new one. From the Treatment of Pediatric Enuresis by the Methods of Lifting the Pot & Uncovering the Canopy, Opening the Orifices & Arousing the Spirit by Wu De-guang & Zhao Ying-feng, Zhong Yi Yao Yan Jiu (Chinese Medicinal Research), 1995, #2, p. The course of dis- ease was as long as six months and as short as 20 days. In most cases, the condition devel- oped in the autumn and winter seasons. Three cases had slimy, yellow tongue fur indicating damp heat, and the remaining children had a pale tongue with a thin, white fur. Mild cases had enuresis one time every 2-4 days, and severe cases had enuresis daily or even sometimes more than two times each evening. In general, the nutritional develop- ment, the essence spirit, and spirit mind were all normal in all members of the treatment group. If there was damp heat, five grams of Long Dan Cao (Radix Gentianae) were added. One packet of these medicinals was decocted in water and administered per day. If the patient was less than seven years old, they used the above dosages. If the child was more than seven years old, they used one and a half times these doses. In addition, the family had to make sure the child refrained from playing excessively in order to prevent their essence spirit from being provoked. At supper, the child was instructed to drink little water and to urinate one time before sleep. Twenty-three cases were cured after taking six packets, while three cases were cured after taking nine packets. In four cases, the enuresis returned after one month, but, after resuming the treatment, the condition was cured again. Discussion: Based on their clinical observations over a long period of time and their reading of the literature, Drs. Wu and Zhao believe that pedi- atric enuresis is basically caused by the lungs not diffusing and downbearing and phlegm turbidity clouding the orifices.
