pain killer

so they say saliva is a potent pain killer 3 times stronger than morphine if I remember correctly.
is it possible to turn your spit into a pill or salve?
my idea is to spit into a container and let it evaporate and scrap up what's left into a powder.
Has anyone done this?
if anyone has knowledge/experience could you give me any tips or ideas?
