Elder is
sometimes referred to as black
elder, black elderberry,
or by its Latin binomial,
Sambucus nigra. Elderberry
has several historical applications; among
them are uses as a laxative,
diuretic, diaphoretic (induces
opening of the pores and sweating),
nerve pain (sciatica and neuralgia),
and treatments for rhinitis and sinusitis. A more
modern application of elderberry is
use for viral influenza.
In addition
to its use as a medicinal plant,
elderberry is also used in wine
production and as a flavoring agent.
Persons often confuse elder with another
plant known as American elder (Sambucus
canadensis). The
Non-American elder has a long
history of use, dating as far back
as the Stone
Age. Interestingly, Egyptians used the flowers for
improving complexion and for
applications of soft tissue trauma
(i.e.
burns). American Indian tribes used
elderberry in teas; while 17th
century Englishmen made wine and
cordials from the fruit, which was a
popular remedy for the common cold. [1]
Elder is
associated with a rich history of
superstition as well. In the middle
ages, it was believed that elder
trees were home to witches, and
by cutting them down, one would
incur the wrath of these "evil doers." However, the English and
Russians thought of elder tress as
good luck, and planting one near
home could ward off evil spirits. Sicilians
even believed that sticks made of
elder could kill serpents and drive
away thieves.
Parts Used
The most widely
utilized part of the plant is its
fruit. Elderberries contain
chemicals known as flavonoids.
Among
the primary flavonoids are a sub
grouping known as anthocyanidins. Other constituents include, rutin,
isoquertin, and hyperoside. [2,
3]
Elderberry
also contains many essential oils and
a 3%
concentration of tannins; these constituents add to
the pleasing taste of elderberry
wine. [4]
If consumed raw, and in large
quantities, elderberries have been
reported to cause
nausea. The unripe berries are
considered toxic. However,
when ripened and cooked, the berries have no adverse effects.
Historically, the leaves, flowers,
bark, and berries have all been used
for medicinal purposes. It is
important to note that all
parts of the plant (with the
exception of the berries) contain
poisonous alkaloid chemicals and
cannot be used internally. [5]
Elder Uses
Historic uses of
elder flowers include
application as a mild skin
astringent and wash. This was
thought to improve the complexion
and to relieve skin conditions such as
eczema, acne, and psoriasis. Flowers
were also soaked in water and used
as a gargle in sore throats. When
strained, the flower/water remnant
was used as an eyewash for
conjunctivitis. Additionally, the
flowers and leaves were often
pulverized and combined as
main ingredients for a variety of ointments and
poultices. These topically
applied delivery forms were populare
in reating burns, cuts,
scrapes, and occasional swelling.
Its historical uses offer a prelude to
modern scientific validation for its
effectiveness in treating the common
cold and flu.
The immune-boosting
and anti-inflammatory effects
of elderberry are thought to
be derived from its anthocyanidin
constituents; elder was shown to be
a "cost effective and safe influenza
treatment" in a recent study. [6] Elderberry extract has specific
effects on viruses, inhibiting viral replication
in multiple strains of influenza A
and B. One particular study
has demonstrated
significant improvements in persons taking an elderberry preparation in
comparison to those receiving placebo. [7]
Elderberry
appears to be most effective when
taken within 48 hours of symptom
onset (e.g. cold and flu symptoms). Overall,
elderberry appears to reduce flu
symptoms by roughly 56% in those
using it for a standard treatment
option. [8]
Approximate dosing
for treatment of influenza is
typically 1 tablespoon of elderberry
extract, 4 times per day, for a
minimal duration of 3 - 5
days. In children, one tablespoon
extract, twice per day is
often recommended.

Elder Toxicities & Interactions |
Elder Side
effects
When taken during the
onset of flu symptoms, elderberry
appears to be well tolerated. There
have been no adverse effects
reported in adults or children
taking the extract. [9]
However, this is not to say that
side effects have not occurred.
As mentioned
previously, raw or unripend fruit
may cause nausea, vomiting, and/or
diarrhea. [10]
Elderberry
juice
has been known to cause weakness, dizziness,
stupor, and numbness following
its ingestion. [11]

Due to the status of
elderberry as an immunostimulant,

plant. The more commonly

corticosteroid variety. If using such
medications, consult with a
knowledgeable physician.
