Consonantly whereunto he also tells Us (and Vouches the famous Platerus, for having candidly given the same Advertisement to his Auditors,) that some things have greater vertues, and better suited to our humane nature, when unprepar’d, than when they have past the Chymists Fire; as we see, sayes my Author, in Pepper; of which some grains swallowed perform more towards the relief of a Distempered stomack, than a great quantity of the Oyle of the same spice.
