Vitamin b17 (also referred to as amygdalin or laetrile) is a natural substance that has been used for decades by cancer patients to fight cancer. When taken in by the body, b17 creates a type of cyanide which directly harms cancer cells.
Due to a report about cyanide toxicity, the vitamin was banned for use in this regard in the US. Despite this, some patients still use it as part of their home protocol as it is still available (mainly through the consumption of seeds of fruits such as peaches and bitter almonds.)
Some alternative healthcare practitioners administer Vitamin b17 orally as a pill or in IV form as “there is also no evidence that purified amygdalin, administered in “therapeutic” dosage, causes toxicity.” (2016).
The History of B17 and Why it Was Banned for Use in the US
Originally, amygdalin was a very popular cancer treatment in the USA. This treatment was supported by many case studies that described the anti-tumor effects of amygdalin.
For example, Benzaldehyde, which is one of laetrile’s breakdown products, was tested for anticancer activity in patients with advanced cancer for whom standard therapy had failed. The findings of the research were extremely positive, resulting in an overall objective response rate for 55% of patients (in either complete or partial remission). An additional 37% of patients remained stable, and only 7% of patients showed a progression of the disease.
It is also important to note that no toxicity was associated with the treatment whatsoever, and it was reported that the responses persisted as long as treatment was continued.
Despite these findings, amygdalin was banned for use in many American states in the 1980’s and was deemed ineffective and potentially poisonous.
Recent Supporting Evidence for B17
Even though the ban on the usage of Vitamin b17 has been in effect for many years, it has recently resurfaced, coming to the attention of both scientists and patients. The results of recent in-vitro studies are promising and positive results are beginning to pile up.
The following examples were all published during 2019:
Cancer and Amygdalin:
- Our findings suggest that amygdalin might have an anti-cancer effect due to the various gene expressions in A549, MCF7, and AGS human cancer cells, showing its potential as a natural therapeutic anticancer drug.
- “The results suggest that amygdalin may be a valuable candidate for the treatment of breast cancer, especially in HER2 positive cells”
- “These data support a mechanism of amygdalin antitumor action against breast cancer cells”
Prostate Cancer and Amygdalin:
- “Exposing certain prostate cancer cells to amygdalin might inhibit metastatic spread promoted by this particular integrin”
Oral Cancer and Amygdalin:
- “Extracts of amygdalin from almonds and apricots were effective as an antiproliferative agent which caused apoptosis in oral cancer cell line”
Over the years several reports referred to the possible toxic side effects that vitamin b17 could allegedly cause. Toxicity was only noticed when b17 was administered orally. Some recorded symptoms such as dizziness, headache, nausea and vomiting, are similar to that of cyanide poisoning.
The route of administration of vitamin b17 appears to be associated with the toxic side effects. When administered intravenously, vitamin b17 does not show toxicity: “There is also no evidence that purified amygdalin, administered in “therapeutic” dosage, causes toxicity.” (2016).
Other Reported Benefits of Vitamin B17
- * Serves as an antioxidant, working alongside vitamins A, C, and E to dispose of toxic cells.
- * Alleviates pain caused by arthritis and other kinds of inflammatory diseases.
- * Improves the immune system due to its ability to boost the level of white blood cells in the body.
- * Reduces high blood pressure, thus preventing hypertension.
What Foods Are High in B17?
- * Pits of fruits such as pears, apples, cherries, and plums.
- * Raw nuts – specifically, raw almonds.
- * Seeds of buckwheat, flaxseeds.
- * Vegetables such as lima beans, carrots, beans sprouts.
