Breath
Breath, Offensive. This is due, as a rule, to some local mischief in the mouth, throat or nasal passages. If the last-named be at fault, the condition is called Ozaena (q.v.). If the breath exhaled from the mouth itself be offensive, the teeth and throat should fall under suspicion. Digestive troubles, too, may exist, and cause the mischief; and in exceptional cases the source of trouble may be in the lungs.
