This is the opinion of Galen and Avicenna.

And as the hot and thick wind muddies and makes the wine sour, so the said poisonous vapor muddies The hot and thick wind makes the wine sour. and sours first the spirits, then the humors around the heart, which, once putrefied, boil over; and this boiling is the fever which thence spreads through everything. And more than other fevers, it makes a boil or swelling because it is such poisonous matter that nature strives immediately to remove it as much as it can from the principal members. The said vapor can stain any humor, but especially the blood. Second, the choler. Third, phlegm. Fourth, melancholy.
