Arecanut: India’s popular masticatory —history, chemistry and utilization

  • V. Raghavan
  • H. K. Baruah


To the Indians, Malayans, or the Indonesians, betel-nut chewing is as familiar as chewing gum to the Americans. In India the use of arecanut and its cultivation constitute a distinct agricultural practice scarcely less important than that of other economic crops, but little attention has been given to a proper assessment of the fruit either in India or elsewhere.
