Laetrile, also known as amygdalin or Vitamin B17, is a naturally occurring substance found in the seeds of apricots, peaches, and other stone fruits. It is believed to have potential benefits as a cancer treatment, although its effectiveness remains a controversial topic in the medical community.
Proponents of laetrile suggest that it works by targeting cancer cells while leaving healthy cells unharmed. However, critics argue that there is insufficient evidence to support its use as a cancer treatment and that it may even be harmful.
In this informative guide, we will explore the history, mechanism of action, benefits, side effects, controversy, and legal status of laetrile, as well as its place in alternative and conventional cancer treatments. We will also discuss patient experiences and answer frequently asked questions about this controversial substance.
So, what is laetrile? Let’s dive in and find out.
The History of Laetrile
Laetrile, also known as Amygdalin, was first discovered in the early 1800s by chemist Pierre-Jean Robiquet. It is a substance derived from the kernels of apricots, peaches, and other fruits. In 1952, American biochemist Ernst T. Krebs Jr. became interested in the substance’s potential as a cancer treatment and began to study it.
Krebs was convinced that laetrile could selectively target cancer cells due to their high levels of beta-glucosidase, an enzyme that converts laetrile into cyanide in the presence of water. This theory led to widespread interest in laetrile as a cancer treatment in the 1970s.
However, the use of laetrile as a cancer treatment remains highly controversial. The U.S. Food and Drug Administration (FDA) has not approved laetrile as a cancer treatment, citing a lack of evidence of its effectiveness and concerns about its safety.
The Mechanism of Action
Laetrile’s mechanism of action is still debated in the scientific community. The theory behind its potential cancer-fighting properties is based on the fact that cancer cells have a higher rate of glucose metabolism than normal cells. This leads to increased levels of beta-glucosidase in cancer cells, which, in theory, could selectively release cyanide and destroy the cancer cell while leaving healthy cells unharmed.
However, opponents of laetrile argue that the mechanism is not specific to cancer cells and that the cyanide produced could harm healthy cells as well. Additionally, studies have shown that laetrile is not always converted into cyanide in cancer cells, further calling into question its mechanism of action.
The Controversy and Research
Laetrile has long been a controversial subject in the medical community. Proponents of laetrile argue that it is a safe and effective cancer treatment that has been suppressed by the medical establishment. However, opponents argue that laetrile is an unproven and potentially dangerous treatment that gives false hope to cancer patients.
Most clinical studies have found little to no evidence of laetrile’s effectiveness as a cancer treatment. A review of clinical trials published in 2015 in the Cochrane Database of Systematic Reviews concluded that there was no reliable evidence for or against the use of laetrile in treating cancer.
Despite this lack of evidence, some alternative medicine practitioners continue to recommend and administer laetrile as a cancer treatment. However, the use of laetrile is illegal in the United States, and the FDA has taken action against those who promote or sell the substance.
In conclusion, the use of laetrile as a cancer treatment remains controversial and unsupported by scientific evidence. Cancer patients should speak with their healthcare providers about proven and effective treatments.
How Laetrile Works
Laetrile, also known as amygdalin, is a compound found in the pits of fruits such as apricots, peaches, and plums. It is believed to work as a potential cancer treatment due to its purported ability to target and kill cancer cells while leaving healthy cells unharmed.
The theory behind laetrile’s mechanism of action is that cancer cells contain an enzyme called beta-glucosidase, which breaks down laetrile into cyanide and other compounds. In healthy cells, this enzyme is not present, so laetrile remains intact and does not release cyanide.
The theory further suggests that the cyanide released from laetrile in cancer cells contributes to killing the cancer cells, although this is still a topic of debate. Some researchers argue that the amount of cyanide released from laetrile is not sufficient to harm healthy cells, while others contend that the cyanide could pose a risk to the patient if not administered properly.
Overall, the proposed mechanism of action of laetrile is still a subject of controversy, and further research is necessary to fully understand its potential as a cancer treatment.
Laetrile Treatment
Laetrile, also known as amygdalin or Vitamin B17, is a controversial alternative cancer treatment. It is typically administered orally in pill or injection form. The recommended daily dosage of laetrile for cancer patients varies depending on the severity of the cancer, with dosages ranging from 9 to 75 grams per day.
It is important to note that laetrile is not approved by the Food and Drug Administration (FDA) as a cancer treatment. Therefore, it is not covered by insurance and can be expensive for patients who choose to pursue this alternative therapy.
| Administration | Dosage | Timing |
|---|---|---|
| Pills | 500-1,000 mg | 3 times per day |
| Injections | 2-3 grams | Once a day |
Laetrile treatment can have potential side effects, including nausea, vomiting, headache, and dizziness. These side effects are typically short-term and dissipate once treatment is stopped.
In rare cases, long-term use of laetrile can result in cyanide poisoning. This can lead to symptoms such as fever, confusion, seizures, and even death. It is crucial to follow the recommended dosage and speak with a healthcare professional before starting laetrile therapy.
Laetrile Benefits
Laetrile has been touted by some as a natural and alternative cancer treatment with potential benefits. While it is not approved by the FDA, some people report positive experiences with the use of laetrile as part of their cancer treatment regimen. Here are some potential benefits of laetrile:
- Potential cancer-fighting properties: Laetrile’s active ingredient, amygdalin, is believed to break down into substances that can potentially slow or stop the growth of cancer cells. While more research is needed in this area, some people believe that laetrile may be an effective supplement to conventional cancer treatment.
- Immune system support: One theory behind laetrile’s potential effectiveness is that it may help boost the body’s immune system, which can be weakened by cancer and cancer treatment. Some people believe that laetrile may help the immune system better recognize and attack cancer cells.
- Pain relief: Some people report experiencing pain relief as a result of laetrile treatment. While it is unclear exactly how laetrile may provide pain relief, some believe that it may work by reducing inflammation in the body.
- Natural approach: For those who prefer a natural approach to health and wellness, laetrile may be an appealing option. It is derived from apricot kernels and has been used as an alternative cancer treatment for decades.
Despite these potential benefits, it is important to note that laetrile is not an FDA-approved cancer treatment and should not be used as a replacement for conventional cancer treatment. Any decision to use laetrile should be made in consultation with a healthcare professional.
Laetrile and Cancer
Laetrile, also known as amygdalin or Vitamin B17, is a controversial alternative cancer treatment that is believed to have the potential to slow or stop cancer cell growth. But how exactly does it work?
Laetrile contains a substance called cyanide, which is believed to be toxic to cancer cells. The theory is that cancer cells contain an enzyme called beta-glucosidase, which breaks down laetrile into glucose, benzaldehyde, and cyanide. The cyanide then targets and destroys the cancer cells while leaving healthy cells unharmed.
However, this mechanism of action has been widely debated in the medical community, with many experts arguing that the amount of cyanide released from laetrile is not enough to have any significant impact on cancer cells.
Research on Laetrile and Cancer
Despite the controversy surrounding laetrile, research on its potential as a cancer treatment has been ongoing for several decades. Some early studies showed promising results, with a 1978 study published in The Journal of the American Medical Association reporting that laetrile had an “unequivocal anti-tumor effect” in mice.
However, subsequent studies have not been as positive, and many experts are skeptical of laetrile’s effectiveness as a cancer treatment. The National Cancer Institute conducted a series of clinical trials on laetrile in the 1980s, which found no evidence that it was effective in treating cancer.
Despite these findings, some proponents of laetrile continue to claim that it has the potential to cure cancer, and many patients have turned to the treatment as a last resort.
It is important to note that laetrile is not approved as a cancer treatment by the Food and Drug Administration, and it is illegal to sell or market it as a cancer cure in the United States. Patients who are considering using laetrile as a cancer treatment should discuss their options with a qualified healthcare provider.
