What side effects this plant can have?
This plant can cause severe health issues such as oral leukoplakia, oral submucous fibrosis, teeth discoloration, cancer, and physical addiction. Regular chewing leads to white patches on the inner cheeks and a progressive tightening of the oral tissues that restricts mouth opening. The chemical components also stain the teeth a dark color and significantly increase the risk of developing oral cancers. Furthermore, the stimulant properties of the leaves frequently result in a strong psychological and physiological addiction. These cumulative effects pose a serious threat to long-term dental and systemic health.
According to a study published by "Journal of oral pathology & medicine : official publication of the International Association of Oral Pathologists and the American Academy of Oral Pathology", inflorescence piper betle (IPB) extracts are associated with the pathogenesis of oral mucosal lesions related to betel quid chewing. These IPB extracts exerted an inhibitory effect on the growth of human gingival keratinocytes (GK). Specifically, IPB extract at concentrations of 200-400 microg/ml decreased cell numbers by 20-40% over 5 days of incubation. Additionally, IPB extract at a concentration range of 200-1600 microg/ml inhibited the total DNA synthesis (TDS) and unscheduled DNA synthesis (UDS) of GK. Simultaneous exposure to IPB extract for 1 to 5 days led to degrees of cytotoxicity that were dose- and time-dependent.
