Many of the missionaries provided health care to the freedmen. Burchell moved for his own health to Mount Carey, in the hills above Montego Bay. He established a dispensary, administering to thousands of freedmen annually. He trained local people to assist in dressing of wounds and other procedures. He began to mix his own preparations, based on studies of chemistry in college, in order to be able to care for his people, as he could not afford to import all supplies.
