Laetrile is a partly man made synthetic form of the natural substance amygdalin. Amygdalin is a plant substance found in raw nuts and the pips of many fruits, particularly apricot pips or kernels, b17 and cancer. It is also found in plants like lima beans, clover and sorghum. In the s, laetrile was widely promoted as an anti cancer agent either on its own or as part of a programme with a particular diet, high dose b17 and cancer supplements and pancreatic enzymes.
But there is no scientific evidence that laetrile or amygdalin can treat cancer or any other illness. Despite this, it is still promoted as an alternative cancer treatment. Alternative treatment means that people use it instead of conventional cancer treatments such as cancer drugs or radiotherapy, b17 and cancer. We do not recommend that you replace your conventional cancer treatment with baclofen and migraine type of alternative cancer therapy, such as laetrile, b17 and cancer.
There is no evidence that laetrile can help with cancer, but some people use it because they believe it might:. Taking laetrile as tablets has more side effects than having it as an injection, b17 and cancer. This is because our digestive bacteria and the enzymes in the food we eat break down the laetrile and release cyanide. They usually also suggest that you take high doses of vitamins and follow a special diet. So it can be quite a rigid and complex treatment to stick to, b17 and cancer.
Laetrile contains cyanide, which is a type of poison. So the side effects of laetrile are the same as those of cyanide. It is estimated that eating approximately 50 to 60 apricot kernels, or 50g of laetrile, can cause death. If you take laetrile as tablets, it is very important that you avoid eating other foods that contain amygdalin such as:. It is also important for anyone with liver problems to know that laetrile may cause further damage to their liver.
Most of the websites or magazines promoting laetrile base their claims on unsupported opinions and anecdotal evidence. One animal study claimed that amygdalin slowed the growth of cancer in animals and helped stop tumours spreading to the lungs.
In two laboratory studies, amygdalin has shown anti cancer activity when given with particular enzymes called glucosidase, b17 and cancer. This is probably because the enzymes made the amygdalin release cyanide which killed the cancer cells grown in the lab. But in the body, the cyanide would also damage healthy cells.
Another study claimed that amygdalin might make cancer cells more sensitive to radiation. Cancer cells b17 and cancer the centre of tumours have less oxygen than cells nearer the outside. Lack of oxygen makes the central cells more resistant to radiotherapy.
Apparently, during one study, amygdalin made cells in a laboratory dish absorb more oxygen, b17 and cancer. This research was difference between malignant and benign cancer reported in and has not been confirmed by any other research. They sponsored two published studies in the late b17 and cancer and early s. The first study involved only 6 people and was to test what levels of laetrile were safe.
Only 1 person had any apparent response to laetrile and this only lasted for 10 weeks. The Cochrane Library published a systematic review in It said that the claimed benefits of laetrile are not supported by controlled clinical trials. No one is allowed to sell laetrile in the European Union because there is no evidence that it works, and because of its serious side effects.
Some hospitals and clinics in Mexico offer laetrile. They may use a different type of laetrile than the one available from websites. Some websites encourage people with cancer to travel to the Mexican clinics for treatment. Be careful when reading any websites that promote the use of laetrile or recommend treatment in overseas clinics. Only you can decide whether or not to use an alternative cancer therapy such as laetrile. But stopping cancer treatment such as chemotherapy or radiotherapy for an unproven treatment could be very harmful to your health, b17 and cancer.
We do not recommend that you replace your conventional cancer treatment with any type of alternative cancer therapy. But no reputable scientific cancer organisations support any of these claims. Our advice is b17 and cancer be very cautious about believing this type of information or paying for any alternative cancer therapy over the internet, b17 and cancer.
