Weevil Cough

Tiny mites that live in hay, wheat and flour stores cause this hacking cough. Spending too much time around infested areas will produce a thick, phlegmy cough, shortness of breath and a distinctive throaty rattle to the voice. Quacks often claim inhaling the vapours of various concoctions—many of them highly addictive—can cure it. It can last to upward of 3 days.
