Many people in Hunan and Taiwan Province provinces like eat areca. I heard that eat areca is addicted. What are the advantages and disadvantages of eating it? I heard that girls eat badly.

Betel nut chewing is very popular in Southeast Asia, India, South China and Taiwan Province Province. Although epidemiological studies have found that betel nut chewing is closely related to the occurrence of oral cancer, there are about 200 million people in eat areca, and the number is increasing. There are about two million people in Taiwan Province province. And the proportion is higher in a certain class. The reason may be related to diners claiming that it has the functions of refreshing, quenching thirst, improving vitality, keeping out the cold and being happy.

Composition of Taiwan Province betel nut chewing tablets

Taiwan Province betel nut chewing tablets contain betel nuts, old vines or leaves, lime, licorice honey and spices.

The main components of areca catechu are arecoline, polyphenols, crude fiber, fat and sugar. Arecoline mainly includes arecoline, arecoline, guava and arecoline, among which arecoline is the highest content, followed by arecoline.

Flowers or fruits of betel leaves contain xanthol and eugenol, among which xanthol is the main source of odor when chewing betel nut.

Betel leaves contain clove oil, tannin fiber, fat, sugar and transition metals, but no safrole.

Pharmacology and clinical function

Arecoline is a parasympathetic stimulant, which acts on muscarinic and nicotinic receptors, while arecoline has a weak parasympathetic effect, both of which inhibit GABA in the central nervous system.

Eat areca mainly affects the central and autonomic nerves. In the central aspect, the changes of brain waves and the reaction speed during eat areca were recorded. The experimental results show that eat areca can improve his alertness and make his reaction more sensitive and calm. The periphery is mainly autonomic nervous system. Eat areca will increase the heartbeat, but the blood pressure will increase slightly, and only the first attempt will increase significantly. Based on the change of heartbeat interval, the role of parasympathetic nerve god is discussed. It was found that only by taking more than 3 or 4 tablets in a row can the parasympathetic nerve function appear. The concentrations of adrenaline, norepinephrine and dopamine in blood were measured during eat areca blockade time, and it was found that the former two were significantly increased, while the latter was not significant, which told us that the main function of eat areca was to excite sympathetic nerves.

toxic effect

From 1988 1 month to1month, there were 10 poisoning cases in Taipei Rongzong Poison Center, among which the most common symptoms were dizziness (4 people), hypotension, palpitation and sweating (3 people), vomiting and asthma. Four patients developed symptoms after eating only one upside-down food. There is no difference between the inverted appearance and the common areca nut, but the areca nut with the opposite growth direction contains twice as many alkaloids as the common areca nut, but there is no significant difference in the total phenolic compounds and tannins between them, but the types and contents of polyphenols are different, and this difference.

Recently, Rongzong Poison Center admitted two cases, both of which were caused by drinking alcohol and betel nut at the same time. One of them developed ventricular fibrillation and died, while the other developed ventricular arrhythmia (PSVT) and recovered after treatment. Why can it cause arrhythmia? Is it related to the effect of alcohol on betel nut? In addition, the ratio of alcohol consumption to concentration and whether long-term drinking affects the toxicity of betel nut need further discussion.

conclusion

Betel nut has been labeled as "chewing gum in Taiwan Province Province", which has become the focus of controversy. The different poisoning symptoms caused by eat areca mainly affect the central and autonomic nervous system. Foreign studies have pointed out that asthma patients are prone to asthma attacks because of chewing betel nut, so chewing betel nut may be one of the control and serious factors affecting asthma, but there is no research report on this in China. Does it mean that the different maturity or composition of betel nut leads to different clinical manifestations? Although anticholinergic drugs may be helpful, the most important thing is to treat symptoms in time, and most symptoms can be relieved quickly.
