This article is an examination of and personal reflection on the advan
tages and disadvantages of providing medical care to the Peruvian Cash
inahua during my 84 months of fieldwork. Although providing medical ca
re to the Cashinahua contributed to my gaining rapport with them, it a
lso created tensions and some hostility from their medical specialists
until we established a working relationship wherein I ''treated the s
ymptoms'' and they ''treated the causes.'' In the process there was a
mutual exchange of knowledge. However, providing medical services cons
umed vast amounts of time and energy. Failure in treatment resulted in
tension, hostility, and on one occasion, the threat of death.
