When it comes to treating cancer, B17, also known as laetrile or amygdalin, is often considered. While discussions about B17’s potential benefits have been ongoing for decades, it’s crucial to understand the science behind it and separate fact from fiction.
In this article, we delve into the depths of B17, exploring its historical context, potential benefits, its role in successful alternative cancer treatment, and its modern-day significance.
What is B17 (Laetrile/Amygdalin)?
B17, also known as amygdalin, is a naturally occurring compound with a rich history in cancer treatment. It was first utilized successfully in Russia in 1845 and was later popularized by Dr. Ernst Krebs in the 1950s. Amygdalin is commonly found in apricot seeds, apples, plums, and cherries, as well as in certain nuts such as bitter almonds and some plants. It’s the main component of B17 laetrile treatment, an alternative cancer treatment that has garnered attention for its potential benefits.
The Power of B17 and Laetrile Therapy
Laetrile, often used in alternative metabolic therapy, is a concentrated form of amygdalin designed to work alongside holistic cancer therapies. In practice, laetrile may be given through supervised injection or taken as part of a nutritional plan. Many programs include it as a supportive option for patients with advanced cancer, focusing on comfort, immune support, and whole-body wellness rather than serving as a standalone cure.
The therapeutic concept is based on how certain cancer cell enzymes influence the controlled breakdown of amygdalin, producing small amounts of hydrogen cyanide around weakened tumor tissues. Healthy cells typically neutralize this process, while abnormal cells may be more vulnerable.
This leads some practitioners to explore laetrile as a complementary cancer treatment approach. Early studies on the antitumor activity of amygdalin and its potential toxicity on malignant cells have sparked continued interest, although more modern clinical trial data is still needed.
For some individuals exploring alternative cancer therapy, laetrile acts as a supportive tool. It helps the body manage stress, inflammation, and energy levels while other cancer therapies or lifestyle strategies do the heavy lifting.
Potential Benefits of B17 (Laetrile/Amygdalin)
So, what are the benefits of B17? B17 has been explored for decades for its wellness properties and potential role in cancer therapies. While research is ongoing, many individuals turn to B17 for cancer due to its supportive effects on immunity, inflammation, and cellular balance.
Here is a list of the top benefits of B17 as an alternative therapy.
#1 Antioxidant Properties
B17 boasts potent antioxidant properties that play a pivotal role in defending the body against free radicals. An excess of free radicals has been linked to increased risks of diabetes, heart disease, and cancer. When balanced, free radicals aid in fighting off infections, but an imbalance can lead to oxidative stress and DNA damage.
Incorporating B17 into your diet can naturally enhance your body’s antioxidant defense and is important for long-term cancer prevention and treatment.
#2 Immune System Support
The activity of amygdalin may stimulate beneficial immune responses. Some practitioners use B17 to help people with cancer strengthen white blood cell function during integrative cancer therapies. This supportive effect may be helpful for cancer patients experiencing immune suppression due to illness or treatment.
#3 Regulation of Hypertension
Early laboratory studies examining amygdalin have investigated whether it may influence abnormal cancer cell activity or support apoptosis (programmed cell death). Research reviewing the effects of B17, the effect of amygdalin, and the action of amygdalin on human cancer cells suggests possible antitumor activity of amygdalin. These studies include models involving human breast cancer and carcinoma cells.
While these findings are preliminary and not fully confirmed through large-scale clinical trial data, they continue to fuel interest in metabolic and alternative cancer therapy programs.
#4 Pain Relief
B17 is often noted for helping reduce inflammation, which may ease discomfort for those affected by cancer. By alleviating pain and inflammation, B17 helps patients to resume activities they were previously unable to engage in. These soothing effects may be especially helpful for those integrating B17 into broader complementary and alternative approaches for wellness.
#5. Support for Healthy Blood Pressure & Circulation
Some small studies suggest that amygdalin may help lower blood pressure by relaxing blood vessels and improving circulation. While more evidence to support this is needed, this potential benefit may be meaningful for those seeking natural ways to support cardiovascular health during cancer treatment.
How B17 May Support Brain and Skin Cancer Health
Because amygdalin interacts with cancer-associated enzymes, some experts believe its metabolic behavior may make it relevant for brain and skin cancer support. Certain aggressive cancers, such as melanoma or breast cancer that metastasizes to the brain, possess elevated enzyme activity that may influence the conversion of amygdalin to cyanide at local tumor sites.
In theory, the controlled breakdown of B17 produces micro-amounts of hydrogen and cyanide, which under the right metabolic conditions may help weaken or slow certain tumor patterns through cancer cells by selective sensitization. Though research in humans is still limited, some lab reports examining the toxic effects and toxicity of amygdalin suggest potential pathways that could be explored further, especially in highly resistant cancers.
Food Sources of B17
While B17 is utilized in laetrile therapy, it’s also found in many natural sources. Amygdalin is a natural occurring chemical found in plants and fruit pits, such as apricots, raw nuts, lima beans, clover, and sorghum.
These include:
- Fruit seeds: The seeds found within apricot pits (yes, there are seeds in there!) have some of the highest natural amounts of B17. But apricots aren’t the only fruit whose seeds offer B17. Other fruits include apples, plums, pears, and cherries. Because fruit seeds contain higher levels of B17, it’s essential to consult a doctor before adding them to your diet. They can recommend a daily dose tailored to your specific health needs.
- Flax seeds: In addition to B17, flax seeds are also high in soluble fiber, omega-3 fatty acids, and protein. You can easily incorporate them into your diet by adding them to smoothies, sprinkling them over salad for an added crunch, or baking them into homemade granola. Squash, millet, and buckwheat seeds are also notable sources of B17.
- Berries: Raspberries, elderberries, strawberries, blueberries, and blackberries all contain B17. It is present within the berry itself, as well as within the berry’s tiny seeds. Berries are also high in antioxidants, making them true superfoods.
- Nuts: Almonds offer high levels of B17. They’re also a great source of protein. Feel free to assemble a medley of almonds, macadamia nuts, cashews containing B17, and the fruits listed above for some homemade B17 trail mix.
- Grains: Grains like sorghum and buckwheat provide an abundance of B17. Are you stuck on how to incorporate these into your diet? Sorghum makes tasty and healthy alternatives for rice or quinoa. In its flaked form, it can be added to cereal, cookies, or granola bars.
- Sprouts: Bamboo sprouts, alfalfa sprouts, and mung sprouts all boast high levels of B17. You can incorporate them into salads or sandwiches for added flavor, texture, and crunch.
Exploring Laetrile (B17) Supplements
When it comes to its effects on cancer, laetrile supplements are appealing. And it certainly has a history of use. It is a purified, partly synthetic form of amygdalin known as laetrile, which has been used in alternative cancer treatment varieties since the 1800s.
When in the body, purified amygdalin is converted into hydrogen cyanide, which is believed to kill cancer cells while leaving normal cells unharmed. Past studies have found that this toxicity from laetrile supplements may inhibit the growth of primary tumors, prevent metastasis, and destroy cancer cells.
For Laetrile to yield the best results, it is essential to work with a healthcare professional before incorporating the supplements into your therapy program, as a personalized approach ensures you receive timely dosages and guidance tailored to your specific needs.
What Research Says About B17 and Cancer Relief
Several lab-based studies have explored the effect of amygdalin on carcinoma, cell carcinoma, and tumor cells. One clinical trial from past decades, although controversial, attempted to evaluate laetrile as a cancer treatment but found inconsistent outcomes. The results are often attributed to differences in oral amygdalin dosing, patient variability, and concerns around cyanide levels.
Moreover, modern laboratory research has found that under controlled conditions, amygdalin may trigger apoptosis (programmed cell death) in carcinoma cells. This includes cervical cancer cells, lung cancer models, and even human breast cancer models. Some in-vitro findings showed that amygdalin or B17 may slow cell proliferation or encourage toxic buildup in abnormal tumor tissues.
These findings contribute to growing interest in cyanogenic glycoside products for cancer and whether glycoside products for cancer prevention hold value. Some studies also reported potential benefits when B17 was used alone or in combination with other metabolic strategies.
While there is ongoing debate and limited evidence to support large-scale use, results of the National Cancer Research archives continue to document public interest.
