i found it in early cpn forum posts

"Caffeine appears to work in a different way and instead of inducing Cpn into a replicating state, it may induce it into the elementary body state. This may cause it to lose its resistance mechanism and thereby become susceptible to antimicrobial agents again. Most of the substances people take to feel better have one of these two effects, either inducing Cpn into a replicating state or an elementary body state. In either event there is symptomatic relief as Cpn quit producing inflammatory proteins in their persistent state that stimulate the immune system. It is my opinion that inducing them into the EBi state is the better alternative and so far that seems to be the case with a small number of people in an uncontrolled setting."

does anybody used or uses caffein for treatment ?
