Dr. Ohhira’s Propolis Plus. Iichiroh Ohhira, Ph.D., uses high-quality Brazilian green propolis, known for its high levels of antioxidant cinnamic acid. This antioxidant and antibacterial sub- stance is created by bees to protect their hive from pathogens. Brazilian green propolis is es- pecially powerful due to the rare flora in the region and unique Africanized bees, which have adapted to harsh environmental conditions. Only Dr. Ohhira’s Propolis PLUS combines propolis support with vitamin E (a-Tocopherol and Tocotrienol), flax oil, and fermented vegetable ex- tract with concentrated digestive health benefits.
