Because White tea is the least processed of all the camellia family teas, it has the highest level of anti-oxidants which positively affect the immune system.
A Pace University study proved that White Tea Extract was more effective than green tea at retarding bacterial growth that caused Staphylococcus and Streptococcus infections, pneumonia and dental caries. Results obtained from the model also suggest that it may have anti-viral effects and additional studies indicated that it has anti-fungal properties. According to Milton Schiffenbauer, Ph.D., a microbiologist and professor in the Dept. of Biology at Pace University, Research shows white tea can actually destroy in vitro the organisms that cause disease.
