【ANALYSIS OF FORMULA】: This formula is set up for syndrome of both exu­berance of summer-heat and dampness. It is composed of Six-To-One Powder and Poria Powder with Five Herbs (seen in dampness-dispersing formulae) by adding gypsum and calcite. Being the extremely cold nature, gypsum and calcite are to clear away summer-heat; talc to clear away heat and to facilitate diuresis for indu­cing dampness out through urine. They together act as the main herbs. As the as­sistant herbs, poria, agaric and water plantain can facilitate diuresis to remove dampness. Being pungent flavor and hot nature, cinnamon bark is to strengthen the transformative function of the gallbladder-qi; bighead atractylodes rhizome to strengthen the spleen and dry dampness in order to recover the functions of ascending and descending. They act as the adjuvant herbs. Licorice root is the dis­patcher herb to reinforce qi and harmonize the middle and all the components.
