Apricot kernels (laetrile, amygdalin, Vitamin B17) as an Alternative Cancer
Laetrile, also known as amygdalin or Vitamin B17, has
promoted as an alternative cancer treatment.
Laetrile is a substance found in the
kernels/seeds of many fruits, such
as apricots, apple, and in raw nuts. But the richest source is the bitter apricot kernels, which make certain people just eat
them to obtain the vitamin B17 in its natural form. But to fully understand this alternative cancer
treatment, it is important that we consider its story.
In the1940s, Dr. Ernst T.
Krebs, Sr. and his son Dr. ET Krebs, Jr.
published a document entitled “The Unitarian or
thesis of cancer
“in the Medical Review, New York.
In the years that followed, the team
of father and son did some
research on the co-enzymes and the
possibility that cancer could be caused by
a vitamin deficiency. In the
early 1950s, they hypothesized that
cancer is caused by the lack of an
essential food compound called Vitamin B17
missing in the modern diet.
research, they found out the existence of the kingdom of
Hunza, in the Himalayan
Mountains to the north of
Pakistan, where those people never have cancer. The Hunzakuts consume between 100-200 times more B17 in their diet than the average American, mainly because eating apricot seeds, and also a lot of millet.
But Doctors Krebs and his Son
did not believe at first that the fruit contains substances that can fight
against cancer until they
learn that Hunzakuts also
eat the seeds in apricot kernels,
which are rich in nitrilosides, which will be Vitamin B17
later. The nitrilosides are
particularly prevalent in apricots, peaches, apples,
millet, bean sprouts, buckwheat, and also
in other fruits and nuts seeds, including
bitter almonds. The researchers extracted some glycosides of the plants which contain nitrolosides.
They applied for a patent for the method in order to produce the metabolite
formed by these glycosides,
for clinical use. The team called it "Laetrile".
the Cancer Industry has denied these claims, making it be illegal to
sell B17. They base on the fact that vitamin B17 contains quantities of cyanide,
which is 'deadly'. However, advocates of laetrile say that this is scientifically false; studies show that vitamin B17 is poisonous to cancer cells only, but harmless to healthy tissue.
The people who advocate for vitamin B17 explain that each molecule of B17 contains one unit of hydrogen
cyanide, a unit of benzaldehyde and two units of
glucose (sugar) securely locked
together. For hydrogen cyanide
becomes dangerous, the consumer must
first unlock the molecule necessarily to free it, a trick that
can only be performed by an enzyme
called beta-glucosidase, which is present
throughout the human body, only in
trace amounts in healthy cells, but in large quantities
in cancer cells.
Thus hydrogen cyanide is
unlocked at the site of the malignant tumor (cancer), resulting in radical Cytotoxic (poisonous)
effects to cancer cells, as the unit is unlocked at the same time as benzaldehyde. Cancer
cells get a double whammy, both cyanide and benzaldeyhde! Benzaldehyde
is a deadly poison in itself, but when it
teamed with cyanide, the result is actually a
poison 100 times more deadly than
when acting alone. Cancer cells are literally obliterated, while healthy cells remain intact.
In addition, another mitochondrial enzyme, rhodanese, which
detoxifies cyanide by converting it to thiocyanate, is always present
in much larger quantities than the
enzyme beta-glucosidase released
in healthy tissue has the ability to completely
degrade both cyanide and benzaldehyde in thiocyanate (an harmless substance) and salicylate (which is a pain
killer similar to aspirin).
Interestingly, malignant cancer cells contain no rhodanese at all, leaving them completely without protection from the two deadly poisons. This whole process is known as
selective toxicity, since only
the cancer cells are specifically targeted and destroyed.
Ever since, hundreds of clinical studies have been conducted
by many competent physicians around the
world, including studies run by Dr.
Ernesto Contreras at the Oasis
of Hope Hospital (an Alternative cancer
treatment center in Mexico), have claimed with confidence
that the treatment with therapy B17
is harmless to normal cells. Therefore, apricot
seeds are safe to be consumed by cancer patients. It is much cheaper and safer than
chemotherapy and radiotherapy.
National Cancer Institute (NCI) Version
The National Cancer Institute (NCI) team, from their
side, has conducted two clinical trials on laetrile
in the late 1970s and early
1980s. It was a phase I trial.
The researchers tried to find a dose
laetrile that is safe in six
adult patients with cancer. They also
studied how and when to give laetrile. This trial showed that there were
few side effects, but two patients
who also ate almonds during
treatment developed cyanide poisoning.
A Phase II trial was
held in 1982. During that phase, researchers examined
the effect of laetrile on various types
of cancer. The study included 178
adult patients, most of whom had breast
cancer, colon cancer or lung cancer. During the study, some
patients have reported that their cancer symptoms
were mitigated and their daily
functioning had improved. In about 54% patients,
the cancer had progressed before the end
of trial. Seven months after the end of
treatment, the cancer had progressed in 175 patients, and symptomatic
improvement did not last.
The researchers also reported that adverse effects reported for
laetrile in various studies are similar
to symptoms of cyanide poisoning: nausea, vomiting, dizziness,
cyanosis (skin turning blue because
the blood does not get enough oxygen), nerve
damage, liver damage , low blood pressure, fever, confusion, coma and even death.
Given all these damaging effects, the researchers of
the NCI decided that no further research on laetrile
was necessary after the phase II
However, a great majority of scientists have doubt on the
NCI studies. Alternative Cancer Treatment have approaches been always disregarded by the medical elite.
Therefore, cancer patients need to their own conclusion, go on YouTube to do some research by watching
“A World Without Cancer” by G. Edward Griffin, or
patients who talk about their own experience with apricot seeds, vitamin B17, amygdalin,
