We have found about 40% our patients exhibit a positive test (to at least one of the 4 substances :caffeine which is metabolized into theobromine, paraxanthine and theophylline.
Avoid coffee, tea, yerba mate, chocolate, guarana, and cola Because caffeine is metabolized into theobromine, paraxanthine and theophylline, any problem with any of the substances would implicate all of the plants as possible sources.
