By applying the methods of inter—element meter andmean line,decoction solution of 110 recipes were anal-ysed for the characteristics of distribution of inorganicelements.In those recipes containing more warm-heat drugs,the contents of most elements were higherthan the line of average value,while those with morecool—cold drugs,lower than the mean line,suggest-ing that the distribution value of inorganic elementsmay be a determining factor responsible for the cold-heat quality of a recipe.
