Laetrile Alternative Cancer Treatment Comparison

Other names for Laetrile: amygdalin and B17. This page contains the details that support its ratings on the Comparison table*. Laetrile is best known for its ability to prevent metastases.

Centuries ago our food was rich in Laetrile. However, as our diets have changed Laetrile has been removed. As the quantity of Laetrile decreases in our diet, the rate of cancer has increased proportionately. The Hunza people, who live in isolation in the Himalayan's never contract cancer. However, their diet is exceptionally high in Laetrile. If they start on a modern diet, their cancer rate becomes the same as ours.

Thoughtful gifts for cancer patients: hypnosis CDs, and humor the best medicine.

Foods Rich in Laetrile

When people talk about diet, they use the term "nitriloside" which is basically the same as vitamin B-17, amygdaline, or Laetrile. Nitrilosides are found in over 800 plants, many of which are edible. Apricot Kernels (the seed inside the pit) are the richest source of nitrilosides. Nitrilosides found in most all fruit seeds including apple, peach, cherry, orange, and nectarine. It is also found in millet, wheat grass (not in wheat), lima beans and mung beans. I personally enjoy mung bean noodles which can be obtained at most Asian markets. One mung bean noodle that is made in Taiwan is imported by L&W Group, PO Box 14663 Fremont CA 94539. Of course taking a little Laetrile pill is the easy way to get your Laetrile.

These Treatments are Different

You cannot pick an alternative cancer treatment the same way you pick your other medications. Despite the enthusiastic claims of well meaning people:

A person's unique body chemistry seems to be the most important consideration in selecting an alternative cancer treatment. Only energy medicine offers a selection method that takes body chemistry into account.

What to Do

Consider the cocktail approach to preventing cancer cells from becoming drug resistant. Smart cancer patients are taking three or four treatments each of which were selected by different means such as:

After you have used a treatment for a while, drug resistance can prevent the treatment from continuing to be effective.  Successful cancer patients prevent drug restive cells from developing by using three or more alternative cancer treatments, the cocktail.


During 1950 after many years of research, a dedicated biochemist by the name of Dr. Ernst T. Krebs, Jr., isolated a new vitamin that he numbered B17 and called 'Laetrile'.

When Laetrile interacts with an enzyme called beta-glucosidase, Laetrile breaks down into:

A simple equation: beta-glucosidase + laetrile = toxic cyanide

Cancer cells contain thousands of times more of this beta-glucosidase than noncancerous cells. Benzaldehyde, a known analgesic, is also released at tumor sites by this reaction.

The Laetrile or Trophoblast Theory of Cancer

This section was made into its own web page: Trophoblast Theory of Cancer**


Laetrile seems to work on all types of cancers. It is effective in reducing tumor related pain in more than half of the cancer patients in the study cited below. It also increased survivability of critical patients. It is best known for its ability to prevent metastases. Additional human studies are not yet completed however, there is a great deal of anecdotal evidence that suggests that Laetrile is highly effective on a wide range of Cancers.

A large paper on Laetrile, "Amygdalin Monographic Analysis" contains information on:

McNaughton Foundation Study

In a study sponsored by the McNaughton Foundation in San Ysidro, California, Laetrile was injected into laboratory animals intraperitoneally in dosages of 500 mg/kg. The mean survival time of the Laetrile-treated animals was 70 percent longer than that of the controls. This research was reported at Senate subcommittee hearings on Laetrile in July 1977. (21) In addition, studies conducted at the Pasteur Institute in Paris, using a mouse model with adenocarcinoma, showed that Laetrile-treated mice survived over twice as long as the control group.

NCI Again

NCI decided to proceed with prospective clinical trials, which were conducted by the Mayo Clinic. After a Phase I trial examining dosage and toxicity, a Phase II trial, involving 178 patients with advanced cancers, was conducted. This study, published in the New England Journal of Medicine in 1982, claimed that Laetrile was ineffective as a treatment for cancer. However, Laetrile advocates pointed out that many of the patients selected for the trial (66 percent) had already been subjected to toxic chemotherapy. Another important question involved the quality of the Laetrile being used in the study. In an effort to ensure a proper trial, one of the clinics using Laetrile offered to provide free Laetrile of known quality for the study. This offer was refused. Dr. James Cason of the University of California at Berkeley reportedly tested the substance used in the NCI study and found that it did not contain any amygdalin (Laetrile).


In the 1970s Dr. Kanematsu Sugiura, a highly respected cancer research scientist at Sloan-Kettering, tested Laetrile. Dr. Sugiura's research showed that Laetrile helped prevent the growth of secondary tumors (metastases) in mice, although it did not destroy the primary tumors. He also reported that some of his studies showed that Laetrile can produce a 60-percent reduction in lung metastases. The Laetrile-treated mice appeared healthier and more active than the saline-treated controls. This would support some of the claims that Laetrile can improve the quality of a patient's life.

Laetrile and Emulsified Vitamin A

Combination therapy using Laetrile and vitamin A is based in part on the following 1978 study conducted by Harold Manner Ph.D., chairman of the biology department of Loyola University, Chicago. He used a combination of emulsified vitamin A (A-mulsin, produced by the Mugos Company) the same company's Wobe Mugos enzymes and B-17. The results were reported in his book the Death of Cancer: After six to eight days an ulceration appeared at the tumor site. Within the ulceration was a pus like fluid. An examination of this fluid revealed dead malignant cells… The tumors gradually underwent complete regression in 75 of the experimental animals. This represented 89% of the total group. The remaining 9 animals showed partial regression.

When Manner repeated the experiment he tried different combinations of vitamins, enzymes, and Laetrile. His results: Laetrile alone had no appreciable effect, but combinations of enzymes and or vitamin A with Laetrile was significantly more effective that just enzymes and/or vitamin A.

What Enzymes?

Wobe Mugos enzymes are available in the USA as Wobenzym which contains Pancreatin and other enzymes not included in Wobe Mugos. Pancreatin has been recognized for many years as playing an important part in the Laetrile theory of cancer.

Wobe Mugos contains the follow per tablet:


Wobenzym contains the follow per tablet:


New Product from Wobe Mugos

There seems to have been a recent change in contents. Wobenzym is now listing ingredients as (FIP-unit is the measurement of enzyme activity):

Pancreatin 56,000 USP-units
protease (pancreas) Sus Scrofa 300 mg
Papain 492 FIP-unit Carica papaya 180 mg
Bromelain 675 FIP-unit Ananus comosus 135 mg
Trypsin 2160 FIP-unit (pancreas) Sus Scrofa 72 mg
Chymotrypsin 900 FIP-unit (pancreas) Bos taurus 3 mg
Rutosid 3 H20 (Rutin) Sophara japonica 150 mg

Protein Timing

Dr Kelley developed a very successful approach to treating cancer based on supporting the pancreas with emzymes smilar to Wobenzym and a diet based on the patients metabolic type. From Dr. Kelley's Metabolic Cancer Cure Diet on the web site:

"It is not only imperative that the correct kind and quantity of protein be eaten, but of equal importance, it must be taken at a specific time. We have found that regular proteins should be taken at breakfast and lunch only. When this is strictly observed the pancreatic enzymes, used in digestion of protein, are used only about 6 hours. This leaves 18 hours for production of pancreatic enzymes to digest cancer tissue."

Visit the above link for more on Dr Kelley's diet. Dr Kelley is the doctor that cured Steve McQueen (the actor) of cancer. The media incorrectly reported that McQueen died of cancer while taking Laetrile. He did not die of cancer. The tumors in McQueen's body were dead and completely encapsulated; they were of no threat. McQueen insisted that they be removed. The fact that the tumors were dead and encapsulated was proven during the surgery when the liver tumor fell out of Mcqueen's body. Mcqueen died after the surgery for no apparent reason; the surgery was a success. It is note worthy that Mcqueen's vowed to expose the "cancer racket" because he felt that Dr Kelley's approach was the cure for cancer and Kelley was being persecuted to hush-up this cure

Quantity of Papers

In his book "The Cancer Industry" Ralph Moss PhD, states, "Although spokespersons for orthodox medicine continue to deny that there have been any animal study data in favor of Laetrile, this is contradicted by a number of studies, including—but not limited to—those at Sloan-Kettering." Dr. Moss worked at Sloan-Kettering during the Laetrile tests and was responsible for writing press releases regarding these tests.

Conclusiveness of Papers

Dr. Manner announced the results of his Laetrile research publicly instead of in a scientific journal to save time. Peer-reviewed journal publication can often take a year and a half. Dr. Manner felt that this information too important to wait. However, this reduces the acceptability of his results.

Standalone Ability

Although Laetrile was originally considered as a standalone cancer treatment. It has been used more as a treatment to prevent metastases while patients take a different treatment as the primary cancer fighting treatment.

When Laetrile is used as the primary treatment these additional supplements are often used:

Dosage and Ease of Use

If a person wishes to use Laetrile as the primary cancer treatment, the amount required would dictate injectable Laetrile. See the "Dosage" subsection below. If a person is to use Laetrile for metastases prevention, a lower dose is used which can be administered orally.

People who change their eating habits greatly increase the effectiveness of the supplements they take. Consider reading the "General Diet" section of the Cancer Diet page *.


The following dosage information is from "World Without Cancer" by Griffin. There are two goals of Laetrile administration: metastases control and primary cancer treatment.

Metastases Control (oral dosage)

Laetrile can be taken orally for metastases control. As such many people add oral Laetrile to your cancer regiment. However, this approach is not likely to rid a body of established tumors. 

Some bacteria in a person's intestines can cause small amounts of cyanide to be released. For this reason, it is usually suggested that oral doses be limited to 3 grams per day.

Primary Cancer Treatment (IV dosage)

If Laetrile is to be used to remove established tumors the usual dose is 6 to 9 grams, intravenous once a day, usually given for three weeks. Intravenous drip is preferred over an injection because Laetrile is a bit painful if injected unless done so very slowly. LR (Lactated Ringers solution) can be used for dilution when using an IV.

Putting too much liquid into the blood can cause edema so most people just put enough Ringers solution to reduce any burning sensation. 

Precautions used when a patient may not be very strong include running blood chem 8 metabolic panels to check for liver and kidney function or CBC to check H&H and for elevated white count. The waste material caused by using Laetrile can overload liver function.

Also from "World Without Cancer" by Griffin: 1974, Laetrile was being used intravenously at levels of six to nine grams daily. Generally, it takes an accumulation of fifty to seventy grams over a period of about a week or ten days before the patient can report tangible improvement."

From "World Without Cancer" by Griffin, "Dr. Krebs has suggested a minimum level of fifty milligrams of Laetrile per day for normal, healthy adult. Naturally, one who is pre-disposed to cancer would require more, and one who already was afflicted with the disease would need much more. The average apricot seed grown in the United States contains approximately four or five milligrams of Laetrile. But this is an average figure and can vary by as much as a factor of six." I, the webmaster of take one or two of the little 100 milligram Laetrile pills every day. I also take one or two Pancreatin pills every day.

Regardless of treatment, recovery is much more likely if the emotional component
is addressed. Visit the Tapping DVD page to learn about the simplest and
most effective method to remove emotional bocks to your healing.

Side Effects

Dr. Ernst Krebs dramatically showed that Laetrile is generally safe. He injected himself with a mega-dose of Laetrile. Dr. Krebs reported no ill effects. Laetrile is safe because each molecule of Laetrile contains cyanide tightly locked up with benzaldehyde and glucose. Only beta-glucosidase can unlock it. Therefore, cyanide is only released at cancer cells because only cancer cells contain beta-glucosidase. Normal cells do not contain beta-glucosidase. The brilliance of Laetrile is that it also releases benzaldehyde at the same time. Benzaldehyde is a deadly poison that acts synergistically with cyanide to produce an an extremely poisonous environment for cancer cells.


There are some reports of muscular weakness and respiratory difficulties in patients taking Laetrile. Usually these side effects are seen in patients who self-administer excessively high doses or who consume large amounts of apricot kernels, which can be quite toxic.

Other side effect indications include dizziness, nausea, vomiting, diarrhea, and fever. It is believed that these symptoms are related to the patient's impaired ability to dispose of the toxic products, as a result of tumor breakdown. In any case, no one should take Laetrile without appropriate supervision and monitoring.

Oral Laetrile is converted to cyanide in the intestines by bacteria. Intravenous Laetrile, in the most common form of administration, appears not to lead to the uncommon side effect of cyanide toxicity.


There have been reports of death and illness in children who took Laetrile tablets accidentally. However, these incidents are not the result of therapeutic administration of the drug.


Taking Laetrile with high strength probiotics may increase the amount of free hydrogen cyanide and thus could create adverse side effects.

Laetrile has not shown any other compatibility issues.

Year Available

Laetrile use became popular in the 1970s.

Cost per Month

If a person is to use Laetrile for metastases prevention, a lower dose is required which could be taken orally. A recommend dose of 3 grams a day would cost about $160 a month. However, if a person wishes to use B-17 as the primary cancer treatment, injectable Laetrile is usually chosen. Each 10 cc (10ml) ampoule contains 3 grams of Laetrile and costs about $8. The usual dose is 6 grams or $16 a day. The course usually runs 21 days for a total of $336.
