‘Uko na dawa neupe?’ (Do you have a white drug?). Penicillin in the form of Penstrep (penicillin and streptomycine) is commonly referred to as ‘white drug’ here in the Maasai land. It is antibiotic but most people use it for completely different purpose. People believe that it is an aphrodisiac due to physical appearance of the drug. Well, solution is white and viscous. They say it looks like semen. People inject penstrep just before bull is about to mount a cow. Yes, it is white viscous solution, but that has nothing to do with libido what so ever. ‘Please don’t inject penstrep to a bull before mating!!!’, I once again exclaim.
