As a member of the xanthine family, it bears structural and pharmacological similarity to theobromine and caffeine, and is readily found in nature, being present in tea (Camellia sinensis) and cocoa (Theobroma cacao).
A small amount of theophylline is one of the products of caffeine metabolic processing in the liver.
