Hot summer is the most annoying season. Only by blowing air conditioning at home and eating cold drinks in your mouth can the body's heat be gradually eliminated. But in ancient times, even the emperor was too hot because there was no advanced refrigeration equipment. In order to solve this problem, Tang Jingzong invented a cold drink "Qing Fan", the purpose of which was to cool himself down and relieve the summer heat. However, he didn't expect this "cool breeze meal" to be a deadly "poison".

Tang Jingzong's development of "Qingfeng Rice" should begin in the summer of his second year of succession. It was particularly hot this summer, which made Tang Jingzong very unhappy. In addition, he had a bad temper, so he was a little unhappy, so he beat and scolded the eunuch to vent his anger.

In order to please Tang Jingzong, Li Fengji, the prime minister, found a way to cool off the summer heat in an ancient book. This kind of food is called "Breeze Rice". Later, the monarch and his subjects began to study cool breeze rice. The specific method is: put a bowl of crystal rice (crystal rice), sprinkle with Longjing powder and Borneolum powder, put it in a long-handled gold cup, then put it in icehouse, and take it out for a few hours to eat.

When Tang Jingzong first ate "Qingfeng Rice", he felt a cold air coming on his face as soon as he tasted it. The heat dissipates most of the time, which is really cool. From then on, "Breeze Rice" became a meal in Tang Jingzong. As long as the weather is hot, you will use the "clean fan" to cool yourself down.

However, there are always two sides to everything. "Breeze rice" is cool and well prepared, which is a good way to relieve summer heat, but it is also a talisman. Why do you say that? Because "Qingfeng rice" is poisonous.

We can look at the recipe of "Qingfeng Rice". There are only three kinds of raw materials, namely rice, a dairy product, and dzi powder and borneol. There is no problem with the small formula of dairy products and rice. The key is the following two prescriptions: dzi powder and borneol. In fact, these two materials are similar to the traditional Chinese medicine of borneol.

Borneolum Syntheticum is crystallized by steam distillation from the stems and leaves of Artemisia and Cinnamomum camphora. It is the essence of natural plants. Chinese medicine often uses borneol as medicine to treat red eye, swelling and pain, laryngeal joint pain and aphtha. There are many records about borneol in Chinese medical classics, such as Tang Herbal Medicine: borneol tastes bitter and cold. It is also recorded in "herbs". It tastes bitter, spicy, mild and non-toxic.
