Does caffeine have any therapeutic uses?

Many therapeutic applications of taurine have been investigated. Some conditions that taurine might be useful in treating include: cardiovascular diseases, hypercholesterolemia, epilepsy and other seizure disorders, macular degeneration, Alzheimer's disease, hepatic disorders, alcoholism, and cystic fibrosis. Recent studies show that taurine supplements taken by mice on a high-fat diet reduced their overall weight. Studies have yet to be done on the effect of taurine on obesity in humans.. Recent studies have also shown that taurine can influence(and possibly reverse) nerve blood flow, motor nerve conduction velocity, and nerve sensory threshhold defects in experimental diabetic neuropathic rats (PMID: 16624563 & PMID: P11259114 Pubmed id's).
