CHAP. XVII. Of Chilblaines and their cures.

YOu shall vnderstand, that Chilblaines (as we terme them) are caused of no other thing, then of humors dried, and restrained in our bodies. For in the winter, when it is cold, the pores do shut so close together, that the hu∣mor cannot passe, or come forth, neither by sweat, nor other exhalation or expiration. For that cause, the humors in a young man (who is hote of complexion) may not be kept in; for then nature (which would ease her selfe) sendeth that

exhalation, vnto the extreme parts of the bodie, that is vn∣to the handes and feete; where remaining there is caused that alteration: and in processe of time, the skinne doth o∣pen, and the humor goeth forth; but cannot heale, till the spring, when warme weather commeth in. Howbeit I haue found out a secret to cure them quicklie, and with great ease. First let them bloud, then giue them a dose of our Electuario Angelica: after that let them take our Syrupo solu∣tiuo, six or seuen dayes together not keeping any straight diet or rule. After this annoint them with Oleum philoso∣phorum de cera & terebinthina, at night when they go to bed: and do thus one weeke at the least, and then no doubt thou shalt cure them as I haue often proued. Also the oyle and water of franckinsence, will do the like.
