Award winning microbiologist, lichiroh Ohhira, Ph.D, uses high-quality Brazilian green propolis, known for its high levels of antioxidant cinnamic acid. This antioxidant and antibacterial substance is created by bees to protect their hive. Brazilian green propolis is especially 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 complete Tocotrienol from palm oil), flax oil, and a fermented vegetable extract with concentrated digestive health benefits. Dr. Ohhira's Propolis PLUS contains only select Brazilian green propolis (carefully removed from honey bee hives using a water soluble extraction method), blended with Dr. Ohhira's nutritious fermented vegetable extract, highly absorbent astaxanthin extracted from valuable Haematococcus seaweed, antioxidant vitamin E, and flax seed oil, one of nature's richest source of Omega-3 fatty acids.
