Phellodendron
is actually a tree native to China,
Manchuria, and Japan. The herb
phellodendron should not be
confused with the houseplant
philodendron, as they are completely
unrelated. Phellodendron
has been used by the Chinese medical
system for thousands of years, and
continues to be a common ingredient in
various Chinese
herbal combinations. Phellodendron
was found mainly in formulas that
were directed at treating stomach
problems and diarrhea; other uses
were for inflammatory issues and as
an antibacterial. [1]
While this herb has had extensive
use in Chinese medicine, when based on
modern scientific investigation, the
therapeutic properties of this
'herb' remain relatively
ignored.

Parts Used
Bark is taken from
the tree and comprises the key medicinal
substance, or component. Phellodendron
contains several alkaloid
constituents, the main ones being
berberine, palmitine, and
phellodendrine. Berberine is,
in all probability, the most active ingredient
phellodendron, as it is well known for its
antifungal,
antiparasitic, and antiinflammatory
effects. [2]
Phellodendron
Uses
Phellodendron has
been employed for several conditions
in addition to those previously
mentioned. These include; diabetes,
meningitis, pneumonia, tuberculosis,
infections of the eye, and liver
cirrhosis. Applied topically,
phellodendron has been shown to
exhibit certain antibacterial and anti-inflammatory
effects.
As an antifungal
agent, phellodendron has
been studied for its effectiveness in
treating various strains of candida,
or yeast. Phellodendron shows
remarkable effectiveness against
many different types of candida. [3]
Investigators attribute the strong
antifungal effect of the herb to the
berberine and palmitine
constituents.
Phellodendron
may also have useful
immunosuppressive effects; when
given to laboratory animals that
underwent transplantation, those
treated with phellodendron had fewer
organ rejection reactions. [4]
In another similar study,
phellodendron was thought to work in
a different way on the immune system
when compared to standard
immunosuppressive drugs, making it a
useful adjunctive treatment in this
regard. [5]
Phellodendrom is
perhaps best known as an effective anti-inflammatory
agent. Several
studies have been conducted that
support such effects. The main constituent
of phellodendron,
berberine, is thought to prevent
the production cyclooxygenase
(COX)-2 enzymes, which are potent
initiators of inflammatory processes
in the body. [6]
Despite these findings, other
studies have shown that the herb has
anti-inflammatory properties when it
has had the berberine removed from
the preparation. [7]
When applied as a topical treatment
for tissue swelling, phellodendron
was able to effectively reduce
several agents that are responsible
for swelling in the skin. [8]
As an anti-ulcer
treatment (which phellodendron
has been used for hundreds of
years), researchers have highlighted
the herb's effectiveness in treating
ulcers. [7]
Other studies investigating
phellodendron's effectiveness in
diabetes treatment showed that the
herb was able to decrease the amount
of damage done to the eyes and
kidneys as a direct result of
disease progression. [9-10]
There is no accurate
dosing information available for
phellodendron at this time.
Typically, it is available as part
of combination herbal formulas.

Phellodendron Side effects
Side effects of phellodendron
are not known
at this time. However, such
instances may be attributable to
its most active constituent,
berberine. Known side
effects of berberine include
lowering of blood pressure and
general malaise. [11]

and any other supplement, herb,
food, or lab test.
Phellodendron Drug interactions

and any pharmaceutical drugs.
Phellodendron Disease conditions
There is concern that
berberine can adversely
affect the heart and circulatory
system; therefore phellodendron (and
berberine) should be avoided by
people with cardiovascular
conditions. [12]
