Dr. Oz, Pain, Hot/Cold Receptors

The production of endorphins in tissues in response to nerve stimulation relieves inflammation and pain. Dr. Oz and the medical community seem to forget that hot and cold receptors in the skin can be readily triggered by natural products in foods, to stimulate the release of endorphins and treat inflammation in nearby tissues.

Hot and Cold Don't Easily Penetrate the Skin
Athletic trainers commonly apply hot and cold packs to avoid swelling and inflammation from injuries, and they are always discussing the virtues of various hot/cold regimens. They ignore the extraordinary efficiency of the circulatory system in regulating tissue temperatures and avoiding temperature changes. They also ignore the fact that chemical "hot and cold" salves and ointments are effective without actually changing the temperature of the skin. The essential observation is that triggering hot and cold sensing nerves is more important than changing the temperature of the damaged tissues.

Common Food Molecules Activate Hot/Cold Nerve Receptors
Peppers are hot, because they contain capsaicin that binds to protein receptors on nerves in the skin, which results in the brain sensation of heat. Camphor and castor oil bind to the same receptors. Menthol binds to corresponding cold receptors. Vicks Vaporub has both menthol and camphor, and therefore stimulates both hot and cold sensors. Vicks is also an effective treatment for tissue inflammation.

Vicks and Castor Oil are Effective Treatments for Pain and Inflammation
A bee sting or a burn on a finger will produce reddening, swelling and pain, that can be quickly alleviated by applying Vicks to the wrist. The hot and cold sensors of the wrist would be stimulated and the returning nerve signals would be generally detected in the whole hand and produce endorphins that would calm the inflammation and sooth the injured finger. In a similar way, an inflamed joint can be treated by topical menthol and castor oil, and lower abdominal discomfort can be alleviated by castor oil applied to the belly.

Tendonitis can be Treated with Peppermint Soap
I have treated a persistent tendonitis in my shoulder by applying Dr. Bronner's Peppermint Soap liberally to my shoulder and waiting a few minutes before continuing my shower. This gentle, persistent treatment produced relief within a week. This was a cure for this persistent inflammation and pain. It also works on joints.

What Dr. Oz needs to communicate is that there are simple ways to stimulate hot/cold receptors that have nothing to do with changing the temperature of deeper tissues, but these treatments are very effective in stimulating general endorphin production that reduces troublesome inflammation and pain. As an addendum, vagal stimulation, i.e. through yoga postures such as shavasana or the Valsalva maneuver, can produce a reduction in general inflammation.

Cure Acne, Back Pain, Tendonitis, Depression

Remedies Include Vicks Vaporub, Castor Oil and Anti-Inflammatory Diet

Simple anti-inflammatory treatments cure some of the most common health complaints. The big question is why people tolerate the problems rather than applying the readily available remedies.

It seems to me that one reason people don’t simply live anti-inflammatory lives and avoid health problems is that attacking the underlying inflammation by approaches that would have prevented the health problem in the first place, is inadequate for fixing the problem after it becomes established.

Health problems based on inflammation may have many different sources of inflammation. Many dietary deficiencies, for example, contribute to inflammation, so what we eat or don’t eat is a major health risk. Other common contributors to inflammation are dental cavities/infections and inadequate exercise.

Common Symptoms of Chronic Inflammation: Acne, Back Pain, Tendonitis, Depression

I have started to ask casual acquaintances if they have any aches or pains, because eliminating dietary sources of inflammation will be evident in relief of these problems. Common complaints are sore joints and tendons related to repeated use. An example is my barber who complained of pain in all of the tendons used to raise his arms to cut hair. Another friend just had her second child and suffered from shooting pains in the tendons of the arm she used to cradle the youngest when she used the other arm on some task.

Simple Anti-Inflammatory Diet Adjustments Get Quick Results

In many cases, a simple change in diet can lower chronic inflammation enough to provide relief from symptoms. Vitamin D deficiency is probably an underlying source of inflammation of most people in the US. So a simple supplement of 2000-5000 IU per day will have noticeable, anti-inflammatory impact on most people.

I recommended vitamin D and fish oil supplements to a friend suffering from chronic back pain. The back pain persisted, but his acne resolved. He stopped taking the supplements, but after physical therapy relieved the back pain, he returned to the supplements as an acne treatment. Now he has long term relief from all of his pains.

Elimination of Dietary Inflammation May Not Resolve Inflammation Based Health Problems

Health problems that start from aggrevated inflammation, may not be eliminated with resolution of the initial cause. My friend’s back ache, for example, didn’t respond to just elimination of deficiencies in his diet. It seemed that the back problems were self-sustaining. After he did exercises to remove the physical aggravation of his back, lack of dietary inflammation prevented the return of the back ache.

Complex Inflammatory Webs

A student of mine suffers from celiac. This is a complex autoimmune disorder of the intestines that is triggered by wheat gluten and is self-perpetuating. Of interest in this context is that celiacs frequently also have back problems. This indicates that the inflammation of the disease is systemic and impacts other tissues. Clearly, reducing dietary inflammation can go only so far in relieving this complex web of reinforcing sources of inflammation.

Simple Anti-inflammatory Interventions

My friend with tendonitis from holding her child got immediate relief from topical application of castor oil and dietary supplements eliminated the problem. Castor oil and capsaicin react with skin heat-sensing neurons to initiate an anti-inflammatory response in adjacent tissue. In a similar way, menthol acts on cold-sensing neurons and relieves pain by reducing inflammation. Vicks Vaporub is a common commercial source of menthol (other sources are blue Listerine mouthwash and Noxema lotion), which give faster relief than longer lasting castor oil for many connective tissue/joint aches. Exercise is another source of relief for inflammation-based aches and pains.

Health: Combinations of Interventions and an Anti-Inflammatory Diet

Anti-inflammatory drugs, such as aspirin, disrupt the molecular signals that produce inflammation and result in relief from inflammation and pain. The common ailments discussed here respond to anti-inflammatory drugs. Depression was mentioned to point out the psychological dimensions of inflammation. Reproduction/birth is controlled at many points by the processes that we call inflammation and the most inflammatory stage is birth. It is not surprising that disruption of the normally rapid resolution of inflammation following birth leads to postpartum depression. It is surprising that postpartum depression can be relieved by anti-inflammatory drugs.

Fighting Inflammation-Based Diseases

Complex diseases such as allergies, asthma, arthritis, vascular/heart diseases, inflammatory bowel diseases, cancers, etc. are all based on chronic inflammation, but they are also self-reinforcing inflammatory diseases. Cures will require elimination of sources of chronic inflammation, e.g. diet, plus disruption of the disease-supporting inflammation, e.g. food/gut flora-stimulation of inflammation of the bowel.

Fundamental to the cure of all diseases is a supporting anti-inflammatory diet and lifestyle.

Simple Remedies

Simple is usually best. Traditional herbal cures are tried and true. I learn a lot about biology by studying what works in herbal medicine. Some simple plant products, such as Vicks Vaporub, are very potent cures for what typically ails you. Castor oil is an excellent topical pain killer.

Herbs and spices excite our senses and dominate cuisines. Cultures are identified by their food, but the use of particular plant materials to food is not a random act of history, nor is it limited to the regions where the herbs and spices first appeared. Research by Paul Sherman at Cornell, and others has shown that herbs and spices that are used in a culture are also the most effective at inhibiting pathogens and parasites where that food is traditionally served.

I must talk about some related experiences that touch on the same subject, but are simply fun explanations of cultural practices. Milk is used in some interesting cultlural practices, because it has very potent anti-viral, anti-bacterial and anti-fungal components -- milk keep newborns well nurished, but also safe from nasty germs, etc. while the immune system the baby matures. Two astoundingly disparate applications of milk come to mind: pruning fruit trees and walking hot coals. I have observed both. I previously worked with plant pathologists and I watched pruners sanitize their shears in milk between trees. The milk stopped the spread of viruses and bacterial pathogens. I also observed firewalking in the Sri Mariamman temple in Singapore. The firewalkers stepped from the coals into a pool of milk to stop infections of their singed feet. In both examples, milk provided an abundance of anti-microbial molecules that were retasked from protecting babies to protecting trees or adult feet.

Herbs and spices are plant products that are toxic to plant pathogens or herbivores, which are retasked to protect people. Some of these, such as the curcumin in turmeric, are potentially more effective that commercial drugs. I want to point out some of the common plant materials that are very useful in our diets and to remedy common infections, aches and pains.

My current champion cure-all is Vicks Vaporub. This thick ointment has the pleasant scent of its ingredients, menthol, eukalyptol, camphor and terpentine. I associate the smell with childhood treatment for congestion. I also remember that my father used to rub it on his arthritic hands to loosen them up before a day’s work. There is a solid physiological basis for the action of Vicks. Many of the ingredients are powerful antibiotics effective against a variety of bacteria and fungi. Vicks is one of the most effective topical treatments for athlete’s foot and ringworm fungal infections. The menthol is cooling, because it binds to the cold sensing receptors and it is an effective analgesic and anti-inflammatory, because it triggers acupuncture like responses through the vagus nerve. I would also try Vicks on autoimmune conditions of the skin, because of both the anti-inflammatory and anti-bacterial properties. I have even seen Vicks recommended for the same reasons for the treatment of acne. TMJ pain and inflammation apparently responds to the menthol.

Castor oil binds to heat detecting receptors of the skin and works similarly to hot pepper capsaicin. Castor oil can be used to stop many aches and pains in arms and legs by topical applications. Since most of these plant products act through the pain sensors in the skin, they don’t actually penetrate to the joints involved, but rather they trigger release of neurotransmitters from nerves that do penetrate to the sites of interest. I also think that the use of castor oil packs applied to the skin of the abdomen, may have systemwide anti-inflammatory impact.

Garlic is the most anti-bacterial of the herbs, but most of the common herbs added to food probably affect the gut flora and shift it to a more anti-inflammatory composition. Many herbs and spices are used as topical cures for acne, because of their combined antimicrobial and anti-inflammatory qualities. Plant materials are very potent. They contain many compounds that are highly effective at low concentrations in neutralizing plant pathogens and herbivores, and so they are also very potent in their impact on the bacteria of our gut and potential on our own systems. Plants are powerful, but just because they are natural does not mean that they are safe. Plants are also rich sources of poisons. Domesticated plants are safer, because we have selected for variants that have lower levels of the compounds that the plants need to otherwise protect themselves. This also means that the compromised varieties need to be sprayed with antibiotics, e.g. apple trees sprayed with streptomycin, fungicides and herbicides. We have traded one group of plant toxins for manmade toxins. All this aside, plants are necessary for our health, but it is better to browse over many different plants than eat a lot of just one. Grains are a relatively recent addition as large components of the human diet, and should also be limited because of their high starch and inflammatory omega-6 oil content.

Turmeric, red pepper and black pepper are commonly ground together and used to enhance many dishes in a variety of different cuisines. It turns out that the curcumin in turmeric and the capsaicin in red pepper are very potent anti-inflammatory agents, but they are enzymatically modified as they are absorbed through the intestines. The black pepper piperine inactivates the enzymes of the intestines and enhances the effectiveness of the other two chemicals. Thus, there has been a lot of trial and error optimization in the use of spices. It makes a lot of sense to eat the way that locals eat when traveling.
