curcumin benefits tumericAre curcumin benefits bogus?

Curcumin is considered the active ingredient of turmeric, which has been used as a traditional medicine on the Indian subcontinent for thousands of years.

I don’t need to tell you that curcumin and turmeric are hot right now. If you read the blogs and Facebook posts, you are led to believe that curcumin and/or turmeric will reduce inflammation; cure cancer and Alzheimer’s Disease; treat erectile disfunction, baldness, and hangovers; and even boost fertility. I haven’t come across any claims they will help you leap tall buildings with a single bound, but maybe I missed that Facebook post.

Where there is smoke, there is bound to be fire. There are dozens of curcumin and turmeric supplements and oils on the market. The companies selling them tell you their claims are based on published scientific studies. But, what if curcumin/turmeric research is bogus? What if the claims are false? What if the products don’t work?

 

How Supplement Companies Mislead You

curcumin benefits misleadingEveryone claims that their products are backed by research studies proving they work, but many of those claims ring hollow. In past issues of “Health Tips From the Professor” I have shared the many ways in which supplement companies try to mislead you with bogus research claims. For example:

  • Some claims of “proof” are completely bogus. They are made up.
  • Some claims are based are what those in the supplement industry call “white papers.”  Simply put, those are impressive looking studies appearing on their website or appearing in their ads that have never been peer-reviewed and published. If they have not gone through peer review and been accepted for publication, you have no idea whether they are valid or not.
  • Some claims are based on what I call “borrowed science.”  Simply put, the company is simply quoting research done on ingredients in their product, not research done on their product. They have no evidence that their product works.
  • Some claims are based on studies published in what I call “advertising journals.”  Simply put, an advertising journal does not submit the studies for peer review. If you are willing to pay their fee, they will publish your study. No questions asked! Again, without peer review you have no idea whether the study is valid.

I have advised you to look for studies done by reputable scientists and published in peer-reviewed scientific journals. In most cases, this is sufficient. But, what if even reputable scientists can be fooled? What if they misinterpreted the experiments they published?

 

How Research Scientists Can Be Fooled About Curcumin Benefits

curcumin benefits researchIt turns out that natural compounds like curcumin are very difficult to work with. They can be deceptive. The claims about the benefits of curcumin and turmeric are a perfect example of how even reputable scientists can be fooled into reporting misleading information. This was highlighted in a recent review, (K.M. Nelson et al, Journal of Medicinal Chemistry, 60: 1620-1637, 2017 ), of hundreds of scientific papers on curcumin.

Curcumin has recently been categorized by medicinal chemists as a natural compound that fits into both the PAINS and IMPS classifications. Before you say: “What are you talking about,” let me sort that statement out for you.  Medicinal chemists specialize in studying the chemical and pharmacological properties of natural compounds and their derivatives. Basically, they start with a natural compound like curcumin and determine whether it might be useful as a drug or a supplement.

PAINS is an acronym for pan-assay interference compounds. In simple terms, this means the compound is a pain to work with (Who says scientists don’t have a sense of humor?) because it interferes with most of the assays used to determine whether it is beneficial or toxic. In the case of curcumin, it binds to proteins, chelates metals, and interferes with fluorescent assays. It causes protein aggregation, membrane disruption, and structural decomposition of cells.

Basically, the authors of the review are saying that most reports of curcumin benefits are based on assays that were inaccurate because the scientist conducting the studies were unaware that curcumin interfered with the assays they were using. They were fooled because they did not fully understand the compound they were working with. They did not know it was a PAINS. Since 2009, at least 15 articles on curcumin have been retracted and dozens have been revised after publication.

The authors said: “While these failures would normally end further research on its use as a therapeutic, they have apparently not deterred researchers [and I would add companies] interested in its development.” Over 100 clinical studies and millions of research dollars have been invested in testing the beneficial effects of curcumin in humans. However, in the words of the authors: ”To our knowledge, curcumin has not been shown to be conclusively effective in a randomized placebo-controlled trial for any indication.”

That has led to its second classification as an IMP (invalid metabolic panacea). Again, you have to love the sense of humor of the scientists who came up with these acronyms.

 

Are Curcumin Benefits Bogus?

 

curcumin benefits misinformationAccording to this review, you can forget about the curcumin benefits you have been hearing about. It turns out that many of the research studies on which those claims have been based are misleading. The scientists who published the study were ethical. They did their best. They simply did not understand that curcumin was a PAINS to work with (pun intended).

Let me very briefly walk you through what the reviewers said about curcumin research.

 

  • In vitro and cell culture experiments produced misleading results because curcumin interferes with the assays used to gauge its biological activity.
  • Publication of these results led to a deluge of blogs and Facebook posts proclaiming the benefits of curcumin. These were repeated so often people started to believe they must be true. Another nutrition myth was born.
  • Unscrupulous manufacturers sensed money to be made. Soon a flood of supplements and oils containing curcumin or turmeric hit the market. Manufacturers claimed their products had miraculous benefits based on the published research (much of which was incorrect).
  • Meanwhile scientists started to meticulously evaluate the probability that curcumin might be a good drug or supplement candidate by looking at its bioavailability and stability. The results of those experiments were not promising.
  • Less than 1% of curcumin is absorbed into the bloodstream. The rest is excreted into the feces, and there is no evidence that it has any beneficial effects on gut microflora.
  • Once it enters the bloodstream, it has a half-life of less than 5 minutes.
  • The breakdown products of curcumin are also unstable and/or have low biological activity.
  • These results should have been enough to halt further interest in curcumin research. However, by that point the claims for curcumin benefits (based in misleading in vitro experiments) had taken on a life of their own. More than 120 clinical trials of curcumin have been conducted at a cost of over 150 million dollars.
  • No double-blinded, placebo controlled clinical trial of curcumin has been successful.

The authors concluded: “Unfortunately, no form of curcumin, or its closely related analogs, appears to posses the properties required for a good drug candidate…The in vitro interference properties of curcumin do, however, offer many traps that can trick unprepared researchers into misinterpreting the results of their investigations. With respect to curcumin/cucuminoids and in vitro studies and clinical trials, we believe there is rather ‘much ado about nothing’.”

The curcumin saga is a cautionary tale. The internet abounds with amazing claims about the benefits of other herbs and spices. Many of the active ingredients of those herbs and spices are also PAINS compounds that interfere with the very biological assays used to assess their benefits. My advice is to take the claims about the miraculous benefits of herbs and spices with “a grain of salt.”  In fact, the most beneficial effect of those herbs and spices is probably the salt they replace in the foods you eat.

 

The Bottom Line

 

Curcumin and turmeric are “hot” right now. The internet is filled with claims about their amazing benefits. There is a flood of supplements and oils containing curcumin or turmeric on the market.

However, a recent review of curcumin has thrown cold water on its supposed benefits. According to the review:

  • Most of the benefit claims for curcumin are based on in vitro and cell culture assays. It turns out that curcumin interferes with these assays giving misleading results. In the words of the authors of the review: “The in vitro interference properties of curcumin offer many traps that can trick unprepared researchers into misinterpreting the results of their investigations.”
  • Curcumin is a very unlikely candidate for a beneficial drug or supplement because:
    • Less than 1% of curcumin is absorbed into the bloodstream. The rest is excreted into the feces, and there is no evidence that it has any beneficial effects on gut microflora.
    • Once it enters the bloodstream, it has a half-life of less than 5 minutes.
    • The breakdown products of curcumin are also unstable and/or have low biological activity.
  • Curcumin has not been shown to be conclusively effective in a randomized placebo-controlled trial for any indication.
  • The reviewers concluded: “With respect to curcumin/cucuminoids and in vitro studies and clinical trials, we believe there is rather ‘much ado about nothing’.”

The curcumin saga is a cautionary tale. The internet abounds with amazing claims about the benefits of other herbs and spices.

My advice is to take the claims about the miraculous benefits of herbs and spices with “a grain of salt.”  In fact, the most beneficial effect of those herbs and spices is probably the salt they replace in the foods you eat.

Headache Relief By Treating Your Shoulder

Posted June 18, 2019 by Dr. Steve Chaney

A Headache Remedy Can be Treating Your Shoulder

Author: Julie Donnelly, LMT –The Pain Relief Expert

Editor: Dr. Steve Chaney

 

 

When you experience the debilitating effects of headache pain, you just want headache relief.

headache relief from painYour head throbs. It’s hard to think. It’s hard to enjoy life.

What should you do?

  • You could take Tylenol or some other drug, but that offers temporary relief at best.
  • You could see a chiropractor, but it may take multiple visits to correct your problem.
  • You could get a massage, but the headache will probably come back.

What you really want is a natural protocol you can use to make the headache go away whenever it occurs. There is such a protocol. It’s called muscular therapy, and I teach people how to perform it on themselves whenever a headache or joint pain occurs.

 

What Is The Difference Between Massage And Muscular Therapy?

There is a difference between massage and muscular therapy as a headache remedy, and both are worthwhile.  Massage is great for moving the fluids (like blood and lymph) through your body and getting muscles to relax. It’s perfect if you’re under stress and you feel like you’re going to explode.  A good massage therapist can have a positive impact on your nervous system and blood pressure, and you’ll come out walking on air.

Muscular therapy, the way I do it anyway, is more focused than it is general.  You’ve heard about spasms, but most people can’t visualize a spasm, so they ignore the term. You probably have an idea that a spasm may be painful, and it isn’t a great thing to have, but what is a spasm?

What is a Spasm

headache relief muscle knotsI explain it as a knot in the muscle.  Through some very complicated physiology (that none of us need to know about) the muscle forms a knot in the thick part of the muscle, and it’s putting a strain on the two ends.

Both ends are attached to a bone, so the pressure causes a strain on the end points and you have pain at the bone.  Most of the time the end points are just after the muscle crosses over a joint, so you end up with joint pain.

 

Too often people think this is arthritis and they are stuck suffering or taking strong drugs to mask the pain.  But in the majority of cases it’s not arthritis, it’s just tight muscles pulling on the bones of the joint and preventing them from moving freely.

But, all you need is to know where the knot (spasm) is, and then apply direct pressure on it.  Hold the pressure for 30 seconds or so, and then let go.  Keep repeating this until it doesn’t hurt anymore.

Headache Relief

headache relief shoulderLet’s say you have headache pain.  There are so many muscles that impact headaches that it would take a book (like my book: “Treat Yourself to Pain-Free Living”) to discuss each of them.  So, let’s just look at one muscle, the Levator Scapulae.

The Levator Scapulae is responsible for lifting your shoulder up.  In fact, the nickname for the Levator Scapulae is “the shrug muscle.” But look at this graphic and you’ll see where the knots form (the round red circles) and where you feel the pain (the red shaded areas).

You may not think to press on your lower neck/shoulder when you feel headache pain.  This muscle also causes the pain you feel in the middle of your back, between your shoulder blades.

 

And self-treatment is so easy!

 

headache relief shoulder muscle workYou can put your opposite thumb into the front of your shoulder as shown in this picture, and your fingers in the back of the muscle. Then squeeze your thumb and fingers so they pinch the entire muscle.

 

headache relief shoulder muscle pressure using wallOr you can put the perfect ball on the very top of your shoulder and then lean into the corner of a wall as shown in this picture.

 

What you are doing is forcing the acid (as in Lactic Acid) out of the muscle fiber so blood can fill the void and heal the muscle fiber.  As you do this you are untying the knot and the pressure is removed from the joint. In most cases the joint can now move more freely and without pain.

All the self-treatments in my book are just this easy!

Most people have significant pain relief, and I am happy to say many get total and permanent pain relief.  Try it yourself, self-treatment is easy.  The worst thing that can happen is nothing, and the best thing that can happen is regaining normalcy.

Why stay in pain when it’s so easy to find the muscular source of the problem and eliminate it?

pain free living book coverGet Treat Yourself to Pain-Free Living . It is filled with over 100 pictures and descriptions proven to show you how to find and self-treat muscle spasms from head to foot!

Join the 1000’s of people worldwide who have discovered that tight muscles were the true source of pains they thought were from arthritis, fibromyalgia, and other serious conditions.  You have nothing to lose, and everything to gain by releasing tight muscles.

Treat Yourself to Pain-Free Living is your step-by-step guide to pain relief!

 

Wishing you well,
