What is Theophylline?

Theophylline is an orally administered xanthine derivative that induces relaxation of smooth muscle in the bronchial tree causing bronchodilation. Theophylline is widely used in therapy of asthma and is not believed to cause liver injury.

It is tonic and skin conditioning. Its cosmetic activity is not clearly or definitively established. It is most often found in anti-cellulite products. Theophylline is in the same family of bio chemicals as caffeine. It is naturally occurring in tea.
