What happened to the lepers of Tracadie?
We don't know the outcome of individual cases, but on October 31, 1901, Dr. Smith reported: "The general health improved; ulcers on the limbs healed rapidly, tubercles disappeared, and swollen faces and hands became reduced to a nearly normal condition. In the cases of those who used the remedies only intermittingly, but little improvement was noticeable."
Chaulmoogra oil seemed to reduce symptoms or slow the progress of leprosy, especially for people in the early stages of the disease. It remained the standard treatment until the 1940s, when it was superseded by new drugs.
