Amygdalin, laetrile, B17, and raw apricot seeds – what’s the difference? Are they the same? Laetrile has been used holistically for cancer since the 1950s. Does it cure cancer? No, but it does fight the disease by targeting malignant cells. It also fortifies the immune system, which is an essential component of any healing protocol.
Amygdalin, Laetrile, B17 and Raw Apricot Seeds
Amygdalin is a natural compound found in apricot kernels, and was first identified by a biochemist, Dr. Ernst Krebs Jr. in 1949. Because it is a naturally-occurring, non-toxic substance, Krebs referred to amygdalin as a vitamin. Hence, the name vitamin B17. In its concentrated form, amygdalin is referred to as laetrile, which is used in integrative oncology therapies.
Unlike chemotherapy, laetrile does not harm normal cells. It targets and kills malignant cells by releasing cyanide. For this reason, laetrile is controversial. Keep in mind, cyanide would have to be given in doses significantly higher than 2,000 mg a day to be toxic.
B17 is found in other foods besides apricot seeds, including raw nuts, certain grains, and the pits of cherries, plums, pears, and apples.
Laetrile and Cancer
The mechanism behind laetrile’s effectiveness lies in a toxic compound called cyanide, and an enzyme called beta glucosidase. Laetrile isn’t selective to just cancer cells, it can be absorbed by non-cancerous cells as well. These healthy cells aren’t harmed, due to an enzyme, rhodanese, which neutralizes the cyanide in laetrile.
Here’s where the magic happens: When laetrile penetrates a cancerous cell, an enzyme, beta glucosidase, breaks up the laetrile molecule, causing it to release cyanide. Cyanide is what kills cancer cells on contact. This process of obliterating cancer cells, while leaving healthy cells untouched, is called “selective toxicity.”

In addition to eradicating cancer cells, laetrile is also an analgesic, which is helpful for reducing pain, and increasing well-being. When laetrile attacks cancer cells, it is transformed into silicate, which is similar to aspirin.
Laetrile is highly effective in treating tumors of the lung, prostate, breast, and colon, along with lymphomas, but is potentially helpful for all types of cancer. However, it is not powerful enough to combat aggressive cancers.
The Best Way To Take Laetrile
Both apricot seeds and laetrile/B17 supplements can be purchased online in the United States, and can be legally consumed as nutritional supplements. Laetrile is safe, with no known toxicity, associated with it.
Here’s what an effective laetrile protocol looks like: one 500 mg capsule, 30 minutes before breakfast, lunch, and dinner, with the last dose given before bed, for a total of 2,000 mg daily. Laetrile can be taken in either capsule or tablet form.
This protocol is used therapeutically for patients with acute and chronic cancer. A large enough dose needs to be taken in order for laetrile to be effective. More is not better, and too high of a dose is ill-advised.
Laetrile is also given intravenously in doses of 12,000 mg. It is used either as direct IV or is diluted with saline, and administered slowly. Those with advanced-stage cancer should consider using IV laetrile.
Laetrile is not an overnight fix for cancer. Rather, it’s used to slow cancer progression, treat pain, boost immunity, and improve quality of life. It is not a stand-alone treatment, but should be used in conjunction with other holistic cancer therapies.
Raw Apricot Seeds
A common question is: “Why can’t I just eat the apricot seeds themselves?” To put this in perspective, you would have to consume one pound of apricot seeds to equal the amount of laetrile in one 500 mg tablet.
The seeds can be used preventatively, but not therapeutically. Approximately 15 apricot kernels are used daily for cancer prevention.
Vitamin B12 is a critical methyl donor, and people who are ill often have low levels of this vital nutrient.
It doesn’t help matters that its absorption is dependent on adequate digestion. More B12 is made in the body when undergoing treatment with laetrile.
This is significant because B12 is a viable treatment for cancer in itself. Vitamin C and minerals are given in conjunction with laetrile, as is vitamin D, to boost immune function. I like making my own liposomal vitamin C.
The Importance Of Enzymes
Pancreatic enzymes are also used alongside laetrile to boost its effectiveness. The outer coating of cancer cells carry an negative electrostatic charge, as do white blood cells. Because like repels like, the white blood cells cannot mount an attack on the cells that are cancerous.
Enzymes are so advantageous because they break down this outer coating, eliminating the negative charge, allowing the cancer cells to be targeted by the immune system. People that are ill, often have inadequate pancreatic function, so supplementing with these powerful enzymes will greatly enhance laetrile’s effectiveness.
Buy Apricot Seeds
IV Laetrile is illegal in the United States, but there are clinics in Mexico that administer this treatment. Supplements can be found online, but should not be distributed across state lines. Apricots seeds, however are legal and can be purchased in health food stores and online.
Check out the book Apricot Seeds – Cancer Cure with Vitamin B17? for a guide on how Vitamin B17 works. Or The Little Cyanide Cookbook for tips and tricks on how to cook delicious meals with foods containing natural sources of cyanide.
Laetrile, also referred to as B17 or amygdalin, is a key player in the integrative cancer world. Identified in the 1949, by Dr. Ernst Krebs Jr., it exerts its anti-cancer effect via an enzyme called beta glucosidase, and a potentially-toxic substance, cyanide. B17 doesn’t affect healthy cells because they lack the beta glucosidase enzyme, and are protected by the enzyme Rhodanese.
Laetrile is also used to increase immune function, and as an analgesic to reduce pain. It can be taken orally via capsules or tablets, or administered intravenously. Apricot seeds can be eaten to prevent cancer, but are not potent enough to be used therapeutically.
