Dr. Shigeaki Sakai of Japan: "Administered to cancer patients, Laetrile has proven to be quite free from any harmful side-effects, and I would say that no anti-cancer drug could make a cancerous patient improve faster than Laetrile. It goes without saying that Laetrile controls cancer and is quite effective wherever it is located."

Canada: Dr N R Bouziane, former Director of Research Laboratories at St Jeanne D’Arc Hospital in Montreal. Dean of the American Association of Bio-Analysts. He also received a doctorate in science from the University of Montreal and St Joseph’s University, an affiliate of Oxford University in New Brunswick. Dr Bouziane’s repeated successes in treating cancers with laetrile were written up in the Cancer News Journal, Jan/April 1971, p.20 under the article heading "The Laetrile Story".

In 1962, Dr. John Morrone reported his results from using Laetrile with 10 patients suffering from "inoperable cancer." The treatments ranged from 4 to 43 weeks in length, and a range of 9 to 133 gms Laetrile was given through intravenous injections. Morrone concluded his report: "The use of Laetrile... in 10 cases of inoperable cancer, all with metastases, provided dramatic relief of pain, discontinuance of narcotics, control of fetor [stench from a tumor], improved appetite, and reduction of adenopathy [swollen lymph nodes]. The results suggest regression of the malignant lesion.... No other side effects [other than transient episodes of low blood pressure] were noted except slight itching and a sensation of heat in the affected areas, which was transitory in all cases."

Dr. Michael Schachter, who has used Laetrile for 20 years with cancer patients, remarks that "As part of a comprehensive health-enhancing program, amygdalin is a useful natural; substance for fighting cancer." Dr. Schachter recommends using cysteine (N-acetyl cysteine is a better-absorbed form of cysteine) along with amygdalin, to maximize the body's ability to detoxify any cyanide released from the Laetrile.

Dr. Douglas Brodie also uses Laetrile to treat his cancer patients. "After years of observing patients using amygdalin, we can say with complete assurance that it is neither toxic nor worthless.... Nor do we find it to be a cure or panacea for cancer. The experience of our clinic... is that amygdalin has the ability to improve the patient's sense of well-being, relieve the pain of cancer, and reduce the requirement for pain medicine."

Dr. Atkins.,M.D.: "Amygdalin (laetrile) is another key component for keeping cancer from growing and should be considered a standard, entirely safe treatment for all cancer patients."

Dr Kearns, DVM. (Dr Kearns uses 50mg of laetrile orally until the leukemia is under control.) "You get cats in with high fevers, 105-108 degrees.  There is nothing you can give them that will bring down that high a fever--except laetrile."


There have been various animal studies that suggest an anti-cancer effect from Laetrile. The SCIND Laboratories in California conducted several experiments [with Laetrile]. In their second study on carcinoma of rats (Walker 256), with amygdalin in doses of 500 milligrams per kilogram injected intraperitoneally on days one, three and six after [transplanted] tumor take, the following results were found:

DAYS SURVIVAL TIME (number of days)
Controls: 19,19,19,19,20,20,22,22,22,22,24,24,24,25,25,26,26, 26,26
Treated: 27,28,28,28,29,29,29,30,30,30,30,30.31,32,32,32,60, 60,60,60

The mean survival time of the control rats was thus 23 days. With the amygdalin-treated rats, mean survival time was 38 days, i.e. a 70% increase over the controls. The survival time of every Laetrile-treated animal was greater than that of every control animal.

" a test by Dr. Paul Reitnauer, chief biochemist of the Manfred von Ardenne Institute, Dresden (East Germany), 20 of 40 H-strain mice were given bitter almonds in addition to their standard diet. Bitter almonds contain relatively high levels of Laetrile. Fifteen days after initiation of this regimen, all 40 mice were inoculated with 1 million Ehriich ascites [cancer] cells. The 20 control mice lived an average of 21.9 days following this injection. The 20 mice receiving the bitter almond supplement lived an average of 25.8 days, which was statistically significant...."

" In 1977, Dr. Vern L. van Breeman of Salisbury State College, Maryland, reported that the addition of apricot kernels [rich in Laetrile] to standard food in pilot experiments with special strains of mice bred to develop breast cancer and leukemia showed impressive differences both in terns of developing the disease and increased survival times between the animals that [ate] the kernels and those that did not. When he reported his early findings... seven of the animals in the leukemia control group and five in the breast cancer [control] group had died, while none of the mice on the kernels had. Ultimately only one of the mammary cancer mice developed a slow-growing tumor, and, while the leukemia results were less impressive in terms of total symptoms, leukemia-prone mice that ate apricot kernels enjoyed life extensions up to 50% over what would normally be expected."

Veteran cancer researcher Kanematsu Sugiura (who had a 4-volume set of his collected scientific papers published in 1965) performed three sets of experiments between September 1972 and June 1973 "to determine the effects of amygdalin...upon mice with spontaneous mammary tumors." In an internal report to his colleagues at Sloan-Kettering Institute, he said that "The results clearly show that amygdalin significantly inhibits the appearance of lung metastases in mice bearing spontaneous mammary tumors and increases significantly the inhibition of the growth of the primary tumor over the appearance of inhibition in the untreated animals."

These are just some of the Laetrile animal studies yielding positive results, while they hardly prove Laetrile to be a "cure" for cancer (which scientific Laetrile proponents have never claimed it to be), they clearly evidence some anti-cancer effect.
