Tell me about the health benefits of eat areca. Personally, I think it is a substitute for chewing gum.

Areca catechu originated in Hainan. Areca nut can be used as medicine. During the Qianlong period 300 years ago, a serious plague broke out in Xiangtan, Hunan Province. At that time, there was no cure, and a large number of people died. Gan met a famous doctor in Guangdong. He used betel nut as medicine for patients and cured the plague. Since then, betel nut has become a tribute of people there. Until now, people in Xiangtan have the habit of chewing betel nuts, but the method of making betel nuts in Xiangtan is different from that in Hainan and Taiwan Province provinces. The betel nut in Xiangtan is made of secret brine, so it tastes good. The most famous betel nut in Xiangtan is the old Xiangtan produced by Bin Zhilang, and 70 yuan is a bit expensive, while the practice in Taiwan Province Province is to process raw betel nuts. I have tasted Taiwan Province betel nut, and I don't like the taste. But it is not good to eat too much betel nut, which is easy to get oral cancer and make your cheeks bigger. If you eat it for the first time, you will have symptoms such as blushing, chest tightness and dizziness. Indeed, rejecting betel nut is far more harmful than chewing gum.
