B17 - Laetrile

Has anyone ever taken B17 to treat cancer. I know it is banned in most countries of the world (except Mexico) as apparently it contains cyanide. Infact it only produces cyanide if it comes into contact with cancer cells. there is a website called living without cancer which puts a fantastic case, and infact states that cancer is caused by a vitamin deficiency. I know there are loads of crackpot cures but the research seems solid.

Are there any vitamins you should not take whilst having chemo (I start on Monday) or any you should take?
thanks.
Carol

Cancer isn’t caused by a vitamin deficiency and there is no such vitamin as B17; you will not find it in any biology book. It was invented in an attempt to give Laetrile, which is a brand name for apricot kernels, credibility and respectability.

Of all the crackpot ‘alternatives’, this is one of the most cracked. And dangerous too because yes, it contains cyanide. There is not a scrap of evidence that it is in any way effective against cancer; certainly it has never been tested in clinical trials.

I can’t find the living without cancer website, but I bet they’re not offering laetrile for free; wherever there’s cancer there’s an unscrupulous charlatan eager to make a fast buck out of people’s desperation and misery.

We should always be wary of stories of miraculous cures and treatments. With such anecdotal evidence there is no way of knowing whether the person ever had cancer in the first place, and, if they did, whether they’re ‘cured’ or even still alive.

These websites give some facts about laetrile:

In fact if ever you’re tempted by an alternative (ie untested and unproven) treatment or cure, it’s worth doing a search for it on Quackwatch to be brought down to earth!

Hi, Carol.

Louise is right - everyone has an axe to grind and money to make - especially cancer cures - like chemotherapy - yours, for instance, could be costing the NHS £45,000 or more and unlike Laetrile/B17 some chemo formulations has been proven to be lethal in some patients, especially 2nd, 3rd and 4th time around. I’m sure that the massive pharmaceutical companies put a small fortune into belittling anything which challenges their supremacy but that doesn’t mean that they are behind all the anti-quackery site, or that information posted there is wrong.

I don’t go a bundle on supplementary vitamins - there’s lots of research these days which shows they don’t have a positive effect divorced from their plant (fruit/veg/herb/nut/seed) source. I followed Bristol’s advice when I had chemo and took loads. I’d advise you to get advice from someone who doesn’t also sell the vitamins (Penny Brohn Cancer Help Centre does in huge quantities at high prices). The only things I supplement are B12, which I can’t get from my vegan vegetarian diet and cod liver oil, which also isn’t on my menu, (to get the DHA essential oil and some vitamin D). I fortify my cereals with brewers yeast which is a primitive single celled plant rich in zinc, vitamin B’s (except B12), chromium and magnesium and selenium and many other minerals and lots of plant protein - great for energy and for calm and optimistic mind and occasionally also Selenium (I prefer this in liquid form ampoules so I don’t have to take supplementary vitamins A,C,E) and eats lots of nuts, seeds, sprouted seeds and beans and vegetable and fruit juices which are all quite concentrated but natural sources of essential foods. All this as organic as possible.

Taking massive doses of antioxidants whilst taking chemo to do oxidative damage to your cells may not make a lot of sense. Healthy cells can take in normal, dietary concentrations of antioxidants to protect themselves. Cancer cells cannot. But there is heavily conflicting evidence on whether, for instance, large doses of vitamin C actually feed tumour cells or not, depending on your body chemistry at the moment you take the vitamins.

Specifically I know that iIf you are receiving Methotrexate you have to avoid folic acid. There are other well known drug/vitamin/herbal interactions.

www.cancerbackup.org.uk has pages on individual chemo products and warnings about interactions. But it’s worth asking your oncology dept. exactly what you’ll be receiving and what to avoid.

Do you yet know what chemo agent you’ll be taking? There are many different agents and combinations.Tell us so others who have taken it can contribute their wisdom and knowledge.

Wishing you well, Carol as you prepare for this new treatment.

On B17, there’s a lot said against it but there is now some high level research going on how to deliver cyanide precursors to cancer cells and Imperial College London has already published some early stage research on this. No doubt when the pharmaceutical companies can make megabucks out of some nano-particle delivery system it will be big business. I don’t accept it is a vitamin - a vitamin is a nutrient which is essential to life. As it is not made in the body or present in food except apple and apricot and peach pips, I cannot believe that humankind would have come so far without it if it were essential to life. I think it is another potent toxin which would kill tumour cells if it ever reached them.

If you are interested, contact the Mexican clinic and ask them for their success stories. There are books written about the subject which suggest it only works for people whose bodies have not been treated with chemo or radiotherapy, discouraging conventional treatment. No one treatment has been shown to work for everyone, B17 included. I wouldn’t rubbish it but until there’s some more independent published evidence but wouldn’t recommend it either for the reasons above.

The essential ingredients in green tea can also kill tumour cells but it’s getting enough of them into the tumour cells in our bodies which is the challenge. I do however drink green tea and as a tea drinker have come to enjoy it. It does me no harm and doesn’t cost a fortune and maybe does me a lot of good too, combined with verything else i do.

Since July 2006 when the first signs of a recurrence appeared, I’m following the advice of the growing number of researchers in the USA who advocate a low-fat vegan diet which is totally nourishing without nourishing or promoting or initiating new tumours. Low-fat BTW doesn’t mean low-fat products, it means less than 10% of your calories in the form of fats or oils. (Read “The China Study”, 2006, by Prof. T. Colin Campbell and visit www.thecancerproject.org and www.pcrm.org) and fatfreevegan.com. This is largely the basis of Prof. Jane Plant’s book, “Your Life in Your Hands” (- latest updated edition August 2007) which contains a lot of detailed information. I’ve also had radiotherapy this year for secondaries in my bones and also take Femara hormonal treatment though my last biospy 4 years ago was only weakly PR + and was considered ER -.

I’m keeping a watchful eye on the Laetrile B17 story. It may be one day recommended in combination with chemo which is designed to promote cancer cell suicide (apoptosis) to amplify this effect if a good delivery mechanism can be made. But as not all tumours occur when own own biological pathways can deliver anti-cancer agents, I doubt it would work in all cases. As I’m not using choosing to use it myself, you’l appreciate I feel sceptical at the moment that even intravenously it could get to where its needed.

I know this is off topic, but you may not have explored meditation. There’s a very simple method, known as mindfulness meditation. There is a Mindfulness-Based Stress Reduction programme offered at a growing number of hospitals and clinics around the world. The programme was devised by a guy called Jon Kabat Zinn who wrote a great (but large) book called Full Catastrophe Living (you can get it from Amazon but have to order the CD’s of the meditations and yoga separately) He also produces a CD called Mindfulness for Beginners which includes 5 guided meditations. This is an excellent starting point. I spent years unsuccessfully starting and stopping meditation. Nothing worked. This mindfulness method is simple and works.

Sending you peace and calm and wishing you a great weekend,
Jenny

Thanks for your comments. The website I refered to is www.worldwithoutcancer.org.uk not living without cancer, its worth a read.

I really do believe that diet plays a big part in the onset and control of cancer and that we are all are different, what works for one does not necessary work for another, we need to find out whats best for us. I am starting FEC chemo on Monday, I have had chemo 12 years ago but apparently it is a slightly different regime, but only slightly different. So much for the millions and millions of pounds spent in cancer research over those 12 years!!!

yes I do believe that large drug companies discredit any kind of “cure” that does not contain anything they can patent, and with the new research into the effectiveness of cyanide maybe they were on the right track with B17. I have spoken to several people who have been taking it with no side effects, it is a natural product, not poison.

I had FEC over 4 years ago, sandwiched with radiotherapy. I shall be thinking of you on Monday. I’m glad to hear you value diet and natural products. I know of people who have had FEC without losing their hair who swear by the veggie juices and organic vegan food they ate.

I used SeaBands on my wrists to prevent vomiting (put them on as soon as I got home and kept them on day and night for the first 2 days) and was never sick - if I felt woosy I went to bed in the dark - this worked. I found bright light was a bad thing and maybe TV would be hard to watch in the first days. (I don’t have one!) Eat/drink little and often to get energy back. I also drank fresh lemon peal and and ginger tea which helped my digestion.

Wishing you well,

Jenny

Thank you Jenny you are so kind. I must admit I am not looking forward to Monday, although I really did not have a bad experience last time, just a unpleasant, the worse things for me were the wait (generally six hours) before the chemo was administered and the smell of the chemicals. the more treatments I had the worse I tolerated the smell, as soon as I got into the chemo suite it made me feel sick, even though I never actually vomited. probably psychological!

Don’t look forward as far as Monday then - you’ve got a lot of agreable living to do between now and then!

Wishing you a peaceful night and a great long weekend starting now! Don’t forget to smell the roses and autumn in the air.

Jenny : - )

Sorry for the very slow reply. I have read a lot about B17 and do not believe that it is quackery. I also think that we should not be so quick to judge alternative options. The conventional treatments are slash, burn and poison - not very broad in terms of immune system, diet and supplements. You may want to try looking up Phillip Day author of ‘Why we’re still Dying to Know the Truth’. He’s too harsh on the medical system so you have to look past that but he does give good info about B17. This vitamin naturally occurs in bitter apricot kernels. My nutritionist recommends taking 10-12 kernels per day. They’re very cheap but very bitter. THe easiest way to take them is to grind them in a coffee grider and then swallow a big spoon full washed down with water. I don’t believe that they are a cancer cure but they do help in the fight against cancer cells.

Hi Swelly
Where can you buy apricot kernels from?
thanks

I’m still sitting on the fence on this one!
I’ve read Phillip Days book and it is interesting but his conspiracy theories are a little far fetched. Icon magazine where i get unbiased up-to-date info on cancer have mixed views on apricot kernals. Bristol cancer centre are very against it and say they have caused liver damage in a few people!? Very difficult to make a decision with so much conflicting advice. If you do decide to take them, dont take too many! (more than 10 aday)
love Julie

Hi

We would recommend that anyone considering complementary therapies should first talk to a medical professional.
I will ask one of nurses for more specific information on this subject.
Kind Regards

Try this website for the apricot kernels: kernelpower.co.uk To be honest I can’t remember which website I used but this one seems OK. Good luck with it. Sorry not to respond sooner - have been away this week celebrating the big shrinkage in my partners liver tumours. She’s on Tamoxifan, zolidex and lots of supplements and organic diet. All the best.

sorry, I am very skeptical of deliberately eating something that nature has made bitter to taste. Generally bitter denotes something not that great to eat.
Plants were the source of many medicines through the ages and, of course, the poisons. Even today our gardens are full of plants that can make us ill and even kill - and what usually stops children eating enough to cause damage is the bitter taste.
I am all for the use of phytotherapy alongside convetional medicine but do please check the practitioners have accredited qualifications. There are many, many quack courses out there.

I’m with you on that one quisie; apricot kernels contain cyanide.

All I can say is I am sure chemo is far more toxic than apricot kernals. They didnt make me feel sick for a week.

I buy the Kernals from local health shop - Julian Graves!!!

Good luck

Oh, apricot kernels do contain cyanide but it’s locked into a molecule that’s harmless to thebody. The molecule only unlocks in cancer cells, killing them. This stuff about apricot kernels containing cyanide which is dangerous is hilarious! They’re actually used in cooking and jams, and have been for quite some time; so clearly they’re harmless. Also the hunza of the himalayas live on them and live to a very old age, and are exceptionally healthy (and never get cancer) so i read.

People in the us have been thrown in jail for selling apricot seeds - probably because they might work - ! Imagine if they did work - how much money drug companies would lose from the sale of chemo drugs; it doesn’t surprise me that so many natural therapies are banned. How can an apricot seed possibly hurt anyone?

I eat apricot kernels, and i’m not dead yet. Surely if they contained dangerous cyanide i would be.

having said that, if you eat a huge amount of anything it’s probably not good for you. The fact that they’re bitter may mean you don’t need to eat many for them to work.

That’s so funny. I came out of hospital went shopping and realised I had a huge craving for amareti biscuits… guess what… made with 20% apricot kernels :wink:

Laetrile does contain cyanide.

There is a very good page on Cancer Research UK about the evidence on laetrile. Basically there is no scientific evidence that apricot kernels offer a cancer cure. This is not a conspiracy but sound scientific evidence.
