| Oregon's Wild Harvest aims to provide
herbs "as nature intended" without chemical processing
and has been focusing on standardizing our growing and manufacturing
processes to bring consistency and quality.
What exactly is a standardized herb and how does it differ from
the historical whole herb?
There is a common misconception that standardization to a marker
compound is always scientific and guarantees an effective product.
This is not always true. For example, hypericin is the marker compound
which is “standardized” in St.
John's wort products. The hypericin, however, accounts for only
0.3% of the standardized herb. What do we know about the other 99.7%
of the extract?
There are thousands of naturally occurring compounds in St. John's
wort. Although herbs have been used for thousands of years, modern
scientific research of herbs is a relatively new phenomenon. In
the race to market standardized herbal products, many herbalists
have found that when we standardize to only one marker compound,
that compound may not be the only bioavailable constituent. In regard
to St. John's wort, there are other flavonoids and a compound called
hyperforin, which has contributed to this herb's medicinal properties.
Historical Perspective
Modern medicine originated with whole herbs. Through technology,
we were able to extract and isolate plant compounds to create tinctures
and pharmacologically pure substances. For example, the opium poppy
became redundant as the whole herb was replaced with a pure white
powder. The drug in this case, is an extremely potent chemical that
has a pharmacological activity in the body.
This philosophy has recently been applied to herbs in the attempt
to make a "standardized herbal drug” by modern European
pharmaceutical companies. This standardization process allows drug
companies to patent manufacturing processes, allowing companies
to use their standardized products in clinical trials. Unfortunately,
because of these standardized products, we have almost lost the
art of healing with whole herbs. We are constantly bombarded by
drug companies and “quick-fixes” made with poorly made
standardized extracts.
Many herbalists believe that herbs are not "magic bullets"
and they should not be treated as such. Many herbs do not target
specific illnesses and chemical pathways, they simply nourish and
balance the body, providing treatment for the body as a whole (the
holistic approach).
What about the need for consistency?
The consumer has more confidence in a product which provides a
measured quantity of a specific compound. Fortunately, the standardized
herbal industry has driven the need for consistent analytical methods,
which can be shared by many laboratories. The importance of this
consistency should be applied to whole herbs, along with the means
to 'fingerprint' and characterize the numerous compounds naturally
present in the whole herb. This type of information can used to
pursue trademarks, and can be used as a way to market a quality
product.
