Laetrile is a powerful anti-tumor agent found naturally in over 1,200 plants. It is best known for its ability to prevent metastases without damaging healthy normal cells.


Apricot seeds contain laetrile

The substance is present in a highly concentrated form in the stones and seeds of fruits such as apricots, plums, peaches and apples. It is a diglucoside, a compound with two molecules of glucose, and contains a cyanide radical that is highly “bio-accessible”, meaning it is able to penetrate through the cellular membrane and reach high intra-cellular concentrations.

Laetrile serves as glucose to healthy cells that provide energy when metabolized. Normal healthy cells contain an enzyme called rhodenase, which “neutralizes” the laetrile by stopping it from releasing cyanide. Malignant cells do not contain this rhodenase enzyme, therefore cyanide radical is released in malignant cells when laetrile is activated, resulting in tumor destruction.

Apple seeds also contain the substance

Laetrile has been scientifically proven to be non-toxic; our own experience with thousands of patients gives us complete confidence that this natural agent poses no danger in treatment.

Cancer cells contain thousands of times more beta-glucosidase enzymes than noncancerous cells.

When Laetrile interacts with beta-glucosidase, it breaks back down into its component structures:

• Two molecules of glucose, a sugar

• One molecule of benzaldehyde, an analgesic (pain-relieving drug)

• One molecule of hydrocyanic acid, a poison

The pharmacological equation could be expressed like this: beta-glucosidase + laetrile = toxic cyanide that is isolated to cancerous cells. The Laetrile/beta-glucosidase reaction also triggers the release of Benzaldehyde, a known painkiller.

Laetrile is very effective in late stage cancers

Effective in reducing tumor related pain, Laetrile increases the survival of late stage cancer patients.

Laetrile was being used intravenously from 1974 onwards at levels of six to nine thousand milligrams daily). An accumulation of fifty to seventy grams of Laetrile over a period of seven to ten days is necessary before patients experience marked improvements.

After treating thousands of patients, the Angeles Functional Oncology team has identified that the most effective method of Laetrile treatment is six grams, intravenously delivered once per day over a period of three weeks. Although Laetrile can be taken orally, the common presence of intestinal bacteria can result in small amounts of cyanide production, meaning oral doses should be limited to three grams or less per day (and therefore a longer program of accumulating treatment is needed).


Laetrile is used in the Angeles hospital program, alongside many other methods. For more information please get in touch through completion of the form on the right.
