Hedford, “Enquiries for Suratte, &c.,” p. 96, Whether the Betele hath such a contrariety to the Durion, that a few Leaves of that, put to a whole Shopful of Durions, will make them all rot suddenly; and whether those that have surfeited on Durions, and thereby over-heated themselves, do, by laying a Leaf or two of Betele upon their Breasts or Stomachs, immediately cure the Inflammations, and Recover.
