Chen Shigong, a master of Chinese medicine surgery in Ming Dynasty, paid attention to the maintenance of spleen and stomach all his life, and his life span reached over 80 years old. He left the recipe of Bazhen cake, praising "serving for a hundred days, being suitable for the elderly, helping Yuanyang and nourishing the spleen and stomach".
Doctors in the Qing Dynasty presented this prescription to Emperor Qianlong. After taking it, he not only said yes, but also insisted on taking it. According to China Historical Archives "With Reference Books", Gan Long often eats Bazhen cake. If not, he personally asked the eunuchs to do it quickly, which shows that he attaches great importance to it.
Luo Dalun, a doctor at Beijing University of Chinese Medicine and a postdoctoral fellow at the Chinese Academy of Traditional Chinese Medicine, said that Bazhen cake is the first cake for health preservation for thousands of years. Luo Dalun said in the book: So, is this Bazhen cake effective? It should be said that the effect is amazing. Many children often catch a cold, and parents take various measures to no avail. After eating Bazhen cake, the spleen and stomach are better, the righteousness is more sufficient, and there are few colds. Bazhen cake is not only good for children, but also good for the elderly.
