Pao Pereira is a tree from the Amazonian rain forest and its bark is traditionally used for boosting the immune system. Pao Pereira might be effective in suppressing the proliferation of virulent viruses and help eliminate or neutralize undesirable cells. It seems able to reduce PSA levels and therefore could be useful for prostate health. By opposing the interference of pollutants, Pao Pereira seems to help support the body’s own immune and detoxification systems. It was Dr. Mirko Beljanski who was among the first to formally research the therapeutic action of Pao Pereira bark when he was at the Pasteur Institute (France).
