A method for producing a fermented and aged placenta solution according to the present invention comprises adding yeast cells having a fermentation activity to a porcine, sheep or horse placenta solution and then fermenting and aging the placenta, wherein brown sugar is added in an amount of 6 to 15% by weight relative to the weight of the placenta solution to the placenta solution to ferment the placenta solution, and the solution is aged after the fermentation. Thus, it becomes possible to provide a method for producing a fermented and aged placenta solution, in which the absorbability of the placenta solution can be improved and the amount of an effective ingredient in the solution can be increased.本發明之課題係提供使胎盤溶液的吸收性或有用成分增加之發酵熟成胎盤溶液的製造方法。本發明之發酵熟成胎盤溶液的製造方法係在豬、羊或馬的胎盤溶液中，加入具有發酵作用之酵母菌而使胎盤發酵及熟成之發酵熟成胎盤溶液的製造方法，其特徵為將相對於胎盤溶液而言以重量比計6~15%的黑糖添加至胎盤溶液中並使其發酵，並在發酵後使其熟成。
