Hello, eat areca is harmful to human body. Areca catechu is a kind of plant, and its fruit can be used to make areca catechu powder, which is very popular in Southeast Asia, but it also has some side effects. Betel nut powder contains fentanyl, which is an anesthetic and can make people have a calming and relaxing effect. However, long-term consumption of betel nut powder will lead to the abuse of fentanyl, resulting in some side effects, such as headache, nausea and dyspnea. In addition, betel nut powder also contains some toxic substances, such as lead and zinc, which may cause harm to human nervous system. Therefore, I suggest you avoid eat areca powder as much as possible, so as not to do harm to your health.
