David Werner's 1977 book called "Where There is No Doctor: A Village Health Care" was widely available-- with Nepali translation during the late 70's. It was called "Doctor Nabhayema". It was a fantastic book. You might want to have a copy of it, but I'm not sure if it is still available. My father used to use that book big time, because he believes in natural herbal or "ayurvedic" medicine.
