The question is, what are the differences between OregaBiotic and the Oreganol P73? Oregabiotic is the gradual release form of spice oils made with multiple wild spice extracts, including the Oreganol P73. This formula is also designed for people with sensitive systems and for those with difficult circumstances, when compromised health is an issue. The combination of oils in the formula brings added benefit and synergy to the individual, more than with Oreganol P73 alone. The powerful antioxidants contained in these spices provide another beneficial attribute of this spice blend, far greater than vitamins C and E combined. Cumin and sage, for instance, are powerful antioxidants when it comes to food spoilage, extending the shelf life of food tremendously-much longer than with synthetic preservatives. Black seed oil is rich in a wide range of fatty acids, particularly the all-important essential fatty acid linolenic acid, and is exceptionally high in phytosterols. Bay leaf, which completes the formula, is extremely high in terpenes and tannic acids, making this one of North American Herb & Spice’s most powerful and unique supplements.
