The difference between Colla Corii Asini Cake and Colla Corii Asini Solid Cream is mainly that the excipients are different.

The main ingredients of Colla Corii Asini Gelatin Cake are sesame seeds, walnuts, rock sugar and yellow wine in addition to Colla Corii Asini. If you've ever bought Colla Corii Asini, you'll realize that the sesame seeds and walnuts inside the Colla Corii Asini cake are in pieces and not ground into a fine powder; because the solid cream is more inclined to nourishing and healing, so in addition to the Colla Corii Asini, sesame seeds, rock sugar, walnuts, and yellow wine, it also adds goji berries and red dates.
