For a long time, Bazhen cake, as the secret recipe of strengthening the spleen for the imperial court, was highly praised by Qianlong and Cixi. Emperor Qianlong, 89 years old, ranks first among the feudal emperors in China and is known as the "ancient emperor". After 60 years in office, he is still healthy and sober after abdication. According to records, the oldest emperor in history personally formulated a dessert formula called Bazhen cake. In his later years, Gan Long often ate Bazhen cake, which has the functions of invigorating stomach and qi, tonifying kidney and strengthening spleen. Bazhen cake is also Cixi's favorite food. No matter whether she is sick or not, she always asks the chef to cook "eight-treasure cakes" for her to eat. 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". 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. From this point of view, Babao cake will definitely have a good effect on gastrointestinal indigestion.
