Look to rural medicine or medical treatments in under-developed areas, mainly for minor ailments/treatments. Some of treatments we have used in Ecuador are materials/supplies the locals can obtain or have on hand:

Use of yogurt (locally produced having active cultures), papaya or ginger for intestinal ailments

A hard-boiled egg daily for vitamin deficiencies

Vinegar mixed with a little alcohol for ear hygiene

Boiled rice (mushy) mixed with a little diluted milk or yogurt, sugar and a dash of salt following bouts of vomiting or diarrhea
