Reducing the Genotoxic Damage in the Oral Mucosa of Betel Quid/Tobacco Chewers

  • Hans F. Stich
Part of the Basic Life Sciences book series (BLSC, volume 39)


Many millions around the world chew areca nuts (several Asiatic countries, South Pacific islands), sun-dried (Khaini tobacco; Bihar) or fermented tobacco leaves (snuff/chewing tobacco; Europe, North America), miang leaves (Thailand), khat (Yemen, Somalia), and coca leaves (South America). These plant products are frequently mixed with slaked lime, as in the case of betel quids (India, Taiwan, Papua, New Guinea), Khaini tobacco, nass or naswar (Uzbekistan, Iran, Afghanistan), or coca leaves (Peru). Some of these oral habits, in particular, the chewing of tobacco-containing betel quids, are causally involved in the etiology of oral carcinomas (7).
