Elderberry is a famous flu remedy from traditional medicine, its recorded medical uses going back at least to the time of the Romans. Unfortunately it has been pigeonholed by modern herbalists as a diaphoretic or diuretic, overlooking its broader potential as an immune-enhancer or “blood cleanser.” See the accompanying article on “bad blood” for a discussion of this term. A recent clinical trial in Israel showed that a preparation not only ended cases of the flu within three days, but increased antibody production. The accompanying Table shows some of its traditional medical uses, including those where immune-stimulating effects appear to be at work. Notice the similarity of this list to that in the accompanying article [See Alteratives: Bad Blood in therapeutics volume] Although this herb is not nearly as well-researched as echinacea, it also appears to have immune-stimulating properties.
Some traditional uses of elderberry
blood purifier gout
bronchitis nasal catarrh
chronic skin ulcers rheumatoid arthritis
diaphoretic sore throats
diuretic spring tonic
The two most frequently-used species of elderberry are the European black elder (Sambucus nigra) and American elder (Sambucus canadensis). The bark and leaves are laxative and can be toxic, as can all parts of other sambucus species with red berries.
elderberry flowers have been traditionally used
to make teas for colds
and sore throats, taken hot before bed. A cup
will usually induce perspiration.
Grieve says: “Refreshing sleep will follow, and
the patient will wake up
well on the way to recovery and the cold or
influenza will probably be
banished within thirty-six hours” (Grieve 1931).
The tea, taken cold daily
was historically considered a spring medicine
and a blood purifier. In
more traditional times, before the advent of
and the industrialization of food, peoples diets
changed radically between
summer and winter. In winter, they ate mainly
meat and stored grains without
fresh fruits or vegetables. Life also tended to
become more sedentary during
the cold weather, with farm work at low ebb.
Thus by spring, people were
sluggish and toxic from the heavy diet, and were
more prone to illness.
Spring tonics, or blood cleansers are a common
traditional remedy in such
societies. Elder was such a tonic in 19th
century Britain. German physician
R.F. Weiss attested to this “spring tonic”
action and says that “the resistance-enhancing
action does indeed comes into play.” He lists
elderberry in his medical
textbook as a treatment for colds and flu (Weiss
Elderberry was an official medicine in the U.S. Pharmacopoeia from the year of its founding in 1820 until 1890, when, along with many other herbal remedies, it was dropped. In North American naturopathic medicine, it has been used as a blood purifier. A naturopathic textbook from the 1950s says that the cold infusion “is an excellent alterative and diuretic in many dermal manifestations of metabolic toxicosis” (Kuts-Chereaux 1952). This, translated, means that it will help detoxify the extracellular fluid. The naturopaths used it both internally and externally for eczema, and applied it externally to “indolent ulcers” and persistent skin inflammations (Kuts-Chereaux 1952)
From these traditional indications, it is clear that elder, among other things, builds up the resistance of the immune system.
Recent research from Israel and Panama has demonstrated that elderberry juice (Sambucus nigra) not only stimulates the immune system, but also directly inhibits the influenza virus (Zakay-Rones et al 1995; Mumcuoglu 1995). The trials used the juice of the berries, made into a syrup — in another traditional form of the elderberry plant. It has less tendency to induce sweating, but is considered effective in most of the same conditions as the tea of the flowers (Grieve 1931). The syrup of the berries will cause nausea if taken in large doses.
Israeli researcher Madeleine Mumcuoglu, Ph.D. of the Hadassah-Hebrew university Medical Center in Ein Karem, Israel, performed the initial research, and found that elder seems to be designed as a specific weapon against the flu virus. The influenza virus forms tiny spikes, called hemagglutinins, which are laced with an enzymes called neuraminidase. The enzyme helps the virus to penetrate the cell walls of a healthy organism. The virus then sets up shop in the cell, reproducing more viruses. The active ingredients that Mumcuoglu discovered disarm the neuraminidase enzyme within 24-48 hours, halting the spread of the virus.
In clinical trials, patients who took the elderberry juice syrup reported fast termination of symptoms. Twenty percent reported significant improvement within 24 hours, 70% by 48 hours, and 90% claimed a complete cure after three days. Patients receiving the placebo required six days for recovery. As proof that elder has more to it than the enzyme-neutralizing constituents, researchers found that the patients who took it also had higher levels of antibodies against the flu virus.
has been proven effective against eight
different influenza viruses. This
may solve the perennial problem of the “mutating
flu.” Viruses have the
ability to alter their genetics and create new
strains. This makes a problem
for creating vaccines against viral diseases,
such as flu or AIDS, because
the vaccine can only be developed against known
strains. The host remains
unprotected against newly evolved forms of the
virus. With the flu virus,
the new evolving forms can sometimes be deadly
as especially virulent strains
develop periodically. We haven’t had an outbreak
of deadly flu in recent
decades, so many people do not realize how
serious the illness can be.
One strain killed more than 100,000,000 people
worldwide in the second
decade of this century — that’s more than have
died in all the 20th century
wars put together. Some epidemiologists have
pointed out in recent years
that we are overdue for another deadly flu
epidemic, which reoccur, like
earthquakes, at regular but not necessarily
predictable intervals. Vaccines
will be of no use against a new strain, at least
when it initially appears.
Elder may thus be able to literally save lives,
because most strains of
the virus use the same enzyme mechanism to
penetrate cells. Elder preparations
may be superior to flu shots for another reason:
50% of people who get
the vaccines report side effects (Zakay-Rones
1995; Mumcuoglu 1995).
Use the tea or the juice rather than the tincture. A syrup of the juice — the same one used in the israeli clinical trial — is available in health foods stores as Sambucol(r).
