[4] "And paints terrestrial constellations with varied flowers."
Among the Indians, who have the most present cures for every disease of their own nation, there is small regard of compound medicines, and less of foreign drugs, because they neither know them nor can use them, but work wonders even with their own simples. With them also the difference of the clime doth show her full effect. For, whereas they will heal one another in short time with application of one simple, etc., if a Spaniard or Englishman stand in need of their help, they are driven to have a longer space in their cures, and now and then also to use some addition of two or three simples at the most, whose forces unto them are thoroughly known, because their exercise is only in their own, as men that never sought or heard what virtue was in those that came from other countries. And even so did Marcus Cato, the learned Roman, endeavour to deal in his cures of sundry diseases, wherein he not only used such simples as were to be had in his own country, but also examined and learned the forces of each of them, wherewith he dealt so diligently that in all his lifetime he could attain to the exact knowledge but of a few, and thereto wrote of those most learnedly, as would easily be seen if those his books were extant. For the space also of six hundred years the colewort only was a medicine in Rome for all diseases, so that his virtues were thoroughly known in those parts. * *
For my part, I doubt not if the use of outlandish drugs had not blinded our physicians of England in times past, but that the virtues of our simples here at home would have been far better known, and so well unto us as those of India are to the practitioners of those parts, and thereunto be found more profitable for us than the foreign either are or may be. This also will I add, that even those which are most common by reason of their plenty, and most vile because of their abundance, are not without some universal and special efficacy, if it were known, for our benefit: sith God in nature hath so disposed his creatures that the most needful are the most plentiful and serving for such general diseases as our constitution most commonly is affected withal. Great thanks therefore be given unto the physicians of our age and country, who not only endeavour to search out the use of such simples as our soil doth yield and bring forth, but also to procure such as grow elsewhere, upon purpose so to acquaint them with our clime that they in time, through some alteration received from the nature of the earth, may likewise turn to our benefit and commodity and be used as our own.
