What is Ashitaba?
Ashitaba is a lush green plant that has its origins
on the Island of Hachijo where the warm tropical
currents pass by on their way North to meet the cold
Arctic waters of the Pacific. Its name means
“tomorrow’s leaf,” aptly termed due to its ability to
reproduce its green stem and leaf almost on a daily
basis.
Extending Your Life Span
Ashitaba’s scientific name,
Angelica keiskei Koidzumi, comes from the Latin name for
“angel,” most likely due to its “heavenly”, well known
health benefits that have given it such notoriety. The
inhabitants of Hachijo Island are well known for their
longevity, having some of the longest life spans on earth
(i.e. many commonly live well into their 90’s in good health). Ashitaba has been an integral part of their diet for hundreds
of years.
When all aspects of their life style were analyzed, the researchers
found that the consumption of ashitaba was a
heavy contribution to their healthy, extended lives. Even
the local residents of the island refer to ashitaba
as the “longevity herb”. As more research has been
conducted on this special strain of angelica, ashitaba has
been attracting more and more attention from the scientific
community.
A Well Guarded Secret
The oldest written record of
the benefits of ashitaba appear to be more than 2,000 years old. Of the many thousands of known plants, |
ashitaba belongs
to the elite 1% category called “medicinal plants.” In
China, ashitaba has had a long history of use to purify the
blood, detoxify the liver, cleanse the colon, improve lung
function, enhance blood circulation, improve nerve dysfunction,
and relieve muscle and joint pain.
From the Ming Dynasty to the Shogun warriors, the ashitaba
plant traveled from China to Japan and was a well guarded
secret of strength and longevity for hundreds of years among
the elite classes of society.
Ashitaba’s Benefits
In traditional Chinese medicine,
ashitaba is considered a superior, strengthening yin tonic. It
has a wide range of known, health-promoting benefits. It
provides immune system stimulation, promotes healthy function of the stomach and intestines, demonstrates
specific anti-viral and anti-bacterial activity and reduces
inflammation.
Other studies show it helps cleanse the blood, regulate blood
sugar levels (anti-diabetic action), promote healthy
cholesterol levels (decreasing unhealthy LDL cholesterol),
stimulates the production of Nerve Growth Factor (NGF) for
excellent nerve function, suppresses cell growth abnormalities
such as tumors (as seen in cancer), helps decrease high
blood pressure, remove toxic wastes from the body, aids natural sleep cycles, improves visual acuity and rovides
peri-menopausal relief. An interesting side benefit many
users of ashitaba have reported their skin feels smoother and
much healthier.

New Research
Why is ashitaba such a giant Super Star among
plants? New research showed the astonishing results that ashitaba
out-performed all other herbs that were tested for their antioxidant
potential based on the ORAC guide (Oxygen Radical Absorbance
Capacity) (in Nutraceuticals World, Sept, 2002). Ashitaba’s phenolic
compounds possess various key properties: antioxidant, anti-inflammatory,
anti-tumorigenic (i.e. stops tumors from growing), anti-carcinogenic
(i.e. stops cancer), antimicrobial (i.e. stops infection),
nerve cell growth enhancer and a detoxifier. What an amazing list of
benefits!
A Unique Super Food
Ashitaba is a true functional Super Food, containing a vast spectrum
of beneficial properties and a unique array of phytonutrients, including
11 vitamins, 13 minerals, chlorophyll, enzymes, carotene, germanium,
saponins, proteins, plant fibers, glycosides, courmarins, and a
potent, rare class of flavonoids called chalcones.
Ashitaba’s rich chlorophyll content helps purify the blood, detoxify
the organs and alkalinize the body. Chlorophyll is also called “green
blood” because its structure is very similar to human blood. Ashitaba’s
natural content of organic germanium promotes the body’s production
of interferon, a key defense substance against harmful viruses
and bacteria. Germanium also helps purify the blood by increasing
oxygen, creating an alkaline pH and activating blood cell replacements.
Chalcones
As scientists began to analyze the reason for the unusual
longevity of the Hachijo Island residents, they discovered that
Ashitaba is the only plant known to contain chalcones, a class of
potent flavonoid compounds.
The chalcones in ashitaba include xanthoangeol, xanthoangelol E and
4-hydroxyderricin. Clinical trials performed on chalcones confirm that
they are potent antioxidants which help to protect the organs from
destructive free radical damage and slow the aging process on a cellular
level. Extensive research has shown chalcones are also antiinfective,
working to prevent pathogens from entering the cells.
Chalcones have been proven to work on the mucus membrane of the
stomach and suppress excessive secretion of gastric juice. They give
rise to ashitaba’s use as a natural diuretic, laxative and a superb aid to
healthy metabolism. Chalcones were also found to inhibit general
inflammatory processes in the body which is true of all flavonoids.
Other Compounds in Ashitaba
Ashitaba also contains numerous other health-boosting
phytonutrients.
Nerve Growth Factor Stimulation. Researchers have found
that the certain compounds in ashitaba can stimulate the production
in vivo [inside the body] of Nerve Growth Factor (NGF). NGF
is an important biological substance that is essential for the development
and survival of neurons in both the central and peripheral
nervous systems.
In one study, those who took ashitaba had a
20% increase in NGF after only 4 days. The nerve growth support
factors in ashitaba can mean critical maximum support for those
with poor or damaged nerve development or nerve injuries.

Coumarins. Ashitaba also contains coumarins (including psoralen,
imperatorin, columbianagin, isorhazelpitin, rhazelpiton, selinidin),
a class of widely occurring phenolic compounds, such as found in
citrus fruits. Coumarins are being studied for their potential
anticarcinogenic properties and preclinical studies show promising
effects against skin tumorigenesis. (Cai, Y, Kleiner H, Johnston
D, Dubowski A, Bostic S, IVie W, DiGiovanni J. “Effect of naturally occurring
coumarins on the formation of DNA adducts and tumors induced
by benzo[a]pyrene and 7,12- dimethylbenz[a]anthracene in skin," Carcinogenesis
18:1521-1527, 1997)
4-hydrodexydelisin glycosides: Ashitaba contains unique glycosides
called isoquercitin, ruteorin, angelic acid and bergapten.
Melatonin. Ashitaba contains a significant amount of melatonin,
a well known antioxidant with benefits of calming the body, stress
reduction, anti-aging and anti-carcinogenic properties.
Natural Vitamins & Minerals: Ashitaba contains a wealth of
naturally occurring vitamins and minerals, including beta-carotene,
vitamin C, calcium, iron and potassium. Ashitaba also contains
vitamin B12, not typically produced in plants. Vitamin B12 has been
recognized for its ability to promote the production of blood cells,
increase attention span and concentration, increase the production
of growth hormone and promote the integrity of the immune
system.
Beware of “Junk” Ashitaba
However, like all nutritional products,
beware of your source of ashitaba. The original, full powered
source of ashitaba is grown on the pristine Hachijo Island contains
the complete range of phytonutrients in full ideal cellular resonance.
Sources that were tested that were grown elsewhere (especially in
the U.S., grown with polluted water in poor soil, etc.) have been like
shadows of the real thing – with extremely deficient cellular resonance
(often chaotic values). It is best to avoid these sources altogether.
The Ashitaba Super Star
Once a well guarded secret of the elite of ancient societies, now we
can all benefit from this medicinal plant Super Star, grown from the
original pristine source — Hachijo Island. Hippocrates, the Father of
Medicine, once said: “Let your food be your medicine.”
And so, we may all envision a time when this incredible Super Food
becomes a household word with every mother asking her children
before they go off to school: “Have you had your ashitaba today?”
To regain and maintain our own ideal health, we must all return to
grass roots of true nutrition – for real, sustaining nourishment of the
body. And by the way, have you had YOUR ashitaba today?
