Vitamin B17 is a naturally occurring chemical compound, famous for falsely being promoted as a cancer cure. It is found in many plants, but most notably in the seeds (kernels) of apricot, bitter almonds, apple, peach, and plum.Amygdalin is classified as a cyanogenic glycoside because each amygdalin molecule includes a nitrile group, which can be released as the toxic cyanide anion by the action of a beta-glucosidase: eating amygdalin will cause it to release cyanide in the human body, and may lead to cyanide poisoning. Neither amygdalin nor laetrile is a vitamin.

Food Source of Vitamin B17

It contains purified amygdalin, which is a compound found naturally in the following :

  • Raw nuts – Such as bitter almonds, raw almonds and macadamia nuts.
  • Vegetables – Carrots, celery, bean sprouts, mung beans, lima beans and butter beans.
  • Seeds – Millet, flaxseeds and buckwheat.
  • Pits of –  Apples, plums, apricots, cherries and pears.
  • Foods with the highest amount of B-17 are apricot kernels and bitter almonds. Almost all fruit pips and kernels are filled with B-17, so eating apple seeds as well as the seeds from other fruits is an excellent way to receive the nutrient.
  • Bamboo Shoots Barley Beet tops Blackberries, boysenberries, cranberries and raspberries Brewer’s yeast Brown rice, buckwheat and millet Butter beans, lima beans, fava beans, and garbanzo beans Cashews, macadamia nuts and pecans Currants Flax seeds Cassava Lentils Loquats Spinach Sprouts Wheatgrass

Health Benefits of Vitamin B17

While most of the research on laetrile focuses on its effects on cancer, some studies have found that amygdalin, the natural form of laetrile, may have other health benefits.

Here are a few possible health benefits of amygdalin:

  • It may lower blood pressure – In one study, amygdalin helped lower systolic blood pressure (upper value) by 28.5% and diastolic blood pressure (lower value) by 25%. These effects were enhanced when taken with vitamin C .
  • It may relieve pain – Several animal studies show that amygdalin may help relieve pain caused by inflammatory conditions, such as swelling, stiffness, or reduced movement. সহজ বাংলা: জয়েন্টের প্রদাহ।" data-rx-term="arthritis" data-rx-definition="Arthritis means joint inflammation causing pain, swelling, stiffness, or reduced movement. সহজ বাংলা: জয়েন্টের প্রদাহ।">arthritis. However, there is a lack of human-based evidence in this area .
  • It may boost immunity – A test-tube study found that amygdalin improved the ability of immune cells to adhere to prostate cancer cells .
  • Its anti-cancerous properties aside – Vitamin B17, especially if derived from natural food sources instead of supplements, can bring in a bevy of health benefits. They include:
  • Regulating Hypertension Vitamin B17 can help regulate hypertension issues due to the formation of thiocyanate, instrumental in lowering high blood pressure.
  • Boosts the Immune System – Vitamin B17 is also known to work wonders for the immune system. Dr. Anju Sood, a Bangalore based-nutritionist, hails the biggest benefit of the vitamin to be its potential to increase white blood cells, which improve immunity.
  • Great Antioxidant – Some experts also claim the ability of the vitamin to associate with other powerful antioxidants like vitamin A, C and E to break down and eradicate toxic cells from our body, thus aiding a natural detox process and promoting overall health.

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Which doctor may help?

Dermatologist or general physician; emergency care for severe allergic reaction.

What to tell the doctor

  • Take photos of rash progression and bring list of new medicines/foods/cosmetics.

Questions to ask

  • Is this allergy, infection, eczema, psoriasis, drug reaction, or another skin disease?
  • Is steroid cream safe for this place and duration?

  • Biopsy only for unclear or serious lesions

Avoid these mistakes

  • Avoid unknown mixed creams, especially on face, groin, children, or pregnancy.

Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
