As one patient said so perfectly: "You can feel the passion and care that goes into their herbal medicine, and each time I place an order I feel better just having called."  - Dr. Chris D.

Background and Use

The ancient Egyptians regarded the Olive tree as a symbol of heavenly power and were the first to put the Olive Leaf to practical use in the mummification of their kings. It continued to be used throughout history for many folk remedies. By the late 1960's, scientific research at a major American pharmaceutical company, conducted experiments with viruses using one of the constituents of this leaf. The majority of the research has taken place in Europe and it warrants further research. Olive Leaf contains numerous antioxidant flavonoids, but the main focus of research has been on the oleuropein compounds.

What is the value of adding standardized extracts to herbal formulas?

We believe that the combination of both the standardized extract and the whole herb creates a more balanced formulation that combines the best of both traditional herbal knowledge and modern scientific research. We add the standardized extract only when we are assured of efficacy and safety of that specific extract. Each herb is assessed on an individual basis to investigate these two important factors:

  • Efficacy: Most of the current scientific studies on herbal medicines have been done using standardized extracts. There are some standardized extracts for which clinical evidence is not compelling (perhaps because the wrong marker constituent has been chosen). Conversely, there are herbs, such as ginkgo, in which the research results for the standardized extract is impressive. In these cases we have added the extract in our product.
  • Safety and Quality: Since the process of extracting an herb concentrates a certain constituent and reduces the other potentially synergistic constituents, the herb is transformed from an herb to a phytochemical. This results in a supplement which is very different from the traditional herbs that the human body has co-existed with over the millennia. Many herbalists believe that the loss of the synergistic constituents may compromise the safety and quality of the herb. Indeed, many standardized extracts do not have the same shelf life as their whole herb counterparts. We share this concern at Oregon's Wild Harvest and have selected only the standardized extracts that we can be assured are safe and stable as well as efficacious.

It is our mission to study whole herbs scientifically and compare them to standardized extracts. We are conducting studies in local academic and clinical institutions using our whole herb products.
