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, or 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 laetrile therapy, an alternative cancer treatment that has garnered attention for its potential benefits.

Potential Benefits of B17 (Laetrile/Amygdalin)

#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.

#2 Immune System Support

One remarkable benefit of B17 is its potential to boost the immune system. By increasing white blood cell count, B17 strengthens the body’s defenses against infections, bacteria, and even cancer cells. This effect is significant for patients undergoing chemotherapy, which can suppress white blood cell production. B17 is a secret weapon, empowering healthy cells to fight against diseases.

#3 Regulation of Hypertension

B17 could help regulate hypertension by lowering blood pressure. High blood pressure can lead to severe medical conditions like heart disease and stroke. Research indicates that B17 can significantly reduce both systolic and diastolic blood pressure, offering a natural way to ease the stress on the heart and extend life.

#4 Pain Relief

B17’s anti-inflammatory properties make it an effective pain reliever. Cancer patients undergoing laetrile therapy have reported improvements in their symptoms. By alleviating pain and inflammation, B17 offers patients the possibility to resume activities they were previously unable to engage in, enhancing their quality of life.

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 help recommend a daily dose for you and your 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 a tasty and healthy replacement for rice or quinoa. In its flaked form, it can be added to cereal, cookies, or granola bars.

Have you ever tried buckwheat pancakes? They’re easy to make with buckwheat flour and add fiber to your diet. You can even top them off with some fresh berries to boost antioxidants.

  • 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.

B17 in the Modern Context: Cancer Research and Future Potential

As research continues, the role of B17 in cancer treatment and prevention continues to be of great interest. The benefits of laetrile therapy make it a powerful addition to any cancer therapy or nutritional program.
