What You Need to Know About Standardized Echinacea

In general, standardization ensures that a certain amount of an
active ingredient exists in each herb dose. Uncertainty remains
regarding which of echinacea’s constituents should be standardized,
or even which constituents boost immunity. Also, putative key
ingredients exist in varying amounts, depending upon the species.
Probably several constituents act in concert.

When asked about the value of standardization, Steven Foster
quoted Rudi Bauer, Ph.D. While speaking at the 1999 International
Echinacea Symposium, Bauer said that judging the quality of an
echinacea product based on phenolic content is like basing a
decision on buying a car on iron content. (Products are usually
based on a group of chemicals called phenolics.) Foster himself
believes that “standardization is irrelevant to the biologic
activity for the intended benefit [which is immune support].”

The bottom line: a body of research supports the use of
fresh-expressed juice of Echinacea purpurea and root tinctures of
all three species (E. purpurea, E. angustifolia, and E. pallida).
One study supports the use of a particular tea (Traditional
Medicinals’ Echinacea Plus). What about tablets and capsules made
of chopped or ground echinacea? Foster dismisses such products as
“junk.” One problem is that a chopped herb can quickly lose its
potency; another is that no research backs up the use of such

Echinacea Dosages

Francis Brinker, N.D., offers the following dosage guidelines
for using echinacea. These are general guidelines—be sure to check
with your health-care practitioner to determine the right dose for

Root tincture: 2 droppersful (about sixty drops) every 2 hours
while awake for the first day of symptoms, then reduce to 2 to 3
droppersful three to four times a day for ten days or until
symptoms resolve.

Juice: 20 drops every 2 hours for the first day, then 20 drops
three times a day for up to ten days. (Or about 8 to 9 ml—11/2 to
almost 2 teaspoons—the first day; then 3 ml—just over 1/2

Tea: Either add 4 teaspoons of chopped root per 2 cups of boiled
water and simmer for 20 minutes, or steep 2 teaspoons of the dried,
chopped herb per cup of boiled water for five to ten minutes.
Strain and drink 3 to 6 cups a day.
