It is a powerful antiseptic. As an external application to rheumatic joints it has achieved marked results. A solution of equal parts of *Ichthyol and water is warmed and applied to the affected joint on calico and covered with heated cloths, outside of which is an impervious fabric to prevent evaporation. Pure *Ichthyol or an ointment of *Lanoline and *Ichthyol may be used instead.
