Many of 0ur patients, especially those who have never experienced acupuncture, have questions about the efficacy of our methods. As it turns 0ut, many western MDs are now practicing Chinese medicine, and now a group of them have put together a website where they will be aggregating studies that prove acupuncture’s effectiveness for many different disorders.  The site is http://www.evidencebasedacupuncture.org/, and we intend to be checking it regularly!

A study in Nature Neuroscience published just yesterday (May 30, 2010) shows one possible mechanism of pain relief through acupuncture:  the release of adenosine.  Adenosine is a very potent anti-inflammatory compound and most chronic pain is caused by inflammation.

For more on this new study from the University of Rochester, check out a general article on it in the UK’s Guardian newspaper by clicking here, or click here to read the study itself.

That’s right, the computer is perhaps one of the leading causes of modern day neck, shoulder, arm and hand pain.  While we cannot magically make the pain disappear without also losing that keyboard or the stress that may accompany the time you spend on your machine, ergonomic adjustments can help to make your quality of life better over the long-term.

Patients with these issues who know me know that I often refer people to my favorite local expert in ergonomics, Deedee Savant, P.T.  Now Deedee is appearing in video online.  She just made me aware of one that’s on Savantmd.com.  For more on the ergonomic adjustments that make a positive difference, check her out at SavantMD.com, and watch the video below…

It’s not officially spring yet, but looking out from my window here in the office, it’s my favorite time:  when the two trees across the street shed their white blossoms.  As soon as the wind blows on a beautiful day like today, the blossoms fall like snow, covering the parking lot and all that’s around them.  Especially gorgeous on a Saturday with no cars in the lots.  I’ve attached a video that perhaps will show some of the blossoms as they fall.  Enjoy!  And remember to set your clocks forward tonight…

A common question I get from patients relates to whether or not it’s ok to take Chinese herbal medicine alongside western/modern medical pharmaceuticals.  While I do not prescribe as many herbal medicines as many of my contemporaries, and while most herbs do not interact in dangerous ways with most pharmaceuticals, there are exceptions.  It’s best to be well informed about herb-drug interactions, and no one I know of is more qualified to comment on this than my friend and colleague John Chen, a trained doctor of Chinese medicine as well as a doctor of western pharmacology.  His response to this concern appears below (excerpted with Dr. Chen’s permission)…

Concurrent Use of Herbal Medicines and Pharmaceuticals – Pharmacokinetic Interactions

by Dr. John Chen, Ph.D., Pharm.D., O.M.D., L.Ac.

The practice of medicine is now at a crossroad: countless patients are being treated simultaneously with both Western and Oriental medicine. It is quite common for a patient to seek herbal treatment while taking several prescription medications. According to JAMA, in 1997, an estimated 15 million adults in the United States (representing 18.4% of all prescription pharmaceutical users) took prescription drugs concurrently with herbal remedies and/or vitamins.

As the general public grows increasingly more open to the use of herbs and supplements, both patients and the health professionals who care for them are becoming more alert to the potential for occasional adverse herb-drug interactions. Safety has become a major topic of discussion. Even though herbal remedies are classified as dietary supplements, it must be noted that if used incorrectly, herbs, like any substance, may adversely affect patients. The safest route of access to herbal therapy is through a well-qualified herbalist.

Although Chinese herbal medicine has been prescribed safely by professionals in the West for many years now, and a great deal of research has been amassed in China, there is still a lack of formal studies that are published in the West to document the safety and efficacy of combining herbs with prescription drugs. Some questions posed by Western healthcare professionals or patients are difficult to answer quickly with documented specifics. However, with some general insights into pharmacology, one can foresee possible interactions and take appropriate precautions to prevent incompatible combinations.

The concept of ‘interaction’ refers to the possibility that, when two (or more) substances are given concurrently, one substance may interact with another, and/or alter its bioavailability or clinical action.
The net result may be an increase or a decrease in the effectiveness of one or both substances. It is important to note that interactions may yield positive effects (achieving better therapeutic effects at lower dosage) or negative results (creating unwanted side effects or adverse reactions). Most of the possible interactions may be classified in two major categories: pharmacokinetic and pharmacodynamic.

Pharmacokinetic Interactions

‘Pharmacokinetic interactions’ refer to the fluctuation in bioavailability of herb/drug molecules in the body as a result of changes in absorption, distribution, metabolism, and elimination.

Absorption
Absorption is the term that describes the process of the physical passage of herbs or drugs from the outside to the inside of the body. The majority of all absorption occurs in the intestines, where herbs or drugs must pass through the intestinal wall to enter the bloodstream. Several mechanisms may interfere with the absorption of drugs through the intestines.

The absorption of herbs may be adversely affected if herbs are administered with drugs that may promote binding in the gastrointestinal (GI) tract. Drugs such as cholestyramine (Questran), colestipol (Colestid) and sucralfate (Carafate) may bind to certain herbs, forming an insoluble complex that decreases absorption of both substances. Because of the large size of the insoluble complex, few or no molecules of either substance pass through the intestinal wall.

Herb absorption may be adversely affected in the presence of drugs that change the pH of the stomach. Antacids, cimetidine (Tagamet), famotidine (Pepcid), nizatidine (Axid), ranitidine (Zantac), and omeprazole (Prilosec) may neutralize, decrease, or inhibit the secretion of stomach acids. With this subsequent decrease in stomach acidity, herbs may not be broken down properly in the stomach, leading to poor absorption in the intestines. To minimize this interaction, herbs are best taken separately from these drugs by approximately two hours.

Drugs that affect gastrointestinal motility may also affect the absorption of herbs. GI motility is the rate at which the intestines contract to push food products from the stomach to the rectum. Slower GI motility means that the herbs stay in the intestines for a longer period of time, thereby increasing the potential absorption. Conversely, more rapid GI motility means that the herbs stay in the intestines for a shorter time, which may decrease absorption. Drugs such as haloperidol (Haldol) decrease GI motility and may increase herb absorption; while drugs such as metoclopramide (Reglan) increase GI motility and possibly decrease herb absorption.

Therefore, it may be necessary to decrease the dosage of herbs when the patient is taking a drug that decreases GI motility and increases overall absorption. Likewise, it is probably helpful to increase the dosage of herbs when the patient is taking a drug that increases GI motility and thus decreases overall absorption.

Distribution
After absorption, herbs or drugs must be delivered to the targeted area in order to exert their influence. ‘Distribution’ refers to the processes by which herbs or drugs (once absorbed) are carried and released to different parts of the body. Currently, it appears that the majority of herbs and drugs do not have any clinically-significant interactions affecting distribution, and thus can safely be taken together. The exception seems to be if a drug has a narrow range-of-safety index and is highly protein-bound, in which case interaction with other substances might occur during the distribution phase. Examples of drugs that have both a narrow range-of-safety index and a high protein-bound ratio include warfarin (Coumadin) and phenytoin (Dilantin).

Unfortunately, it is very difficult to predict whether an individual herb will interact with either one of these drugs because there are no known tests or experiments documenting such interactions.

Metabolism
Once metabolized by the liver, most herbs and drugs become inactive derivatives. The rate at which the liver metabolizes a substance determines the length of time it stays active in the body. If the liver were induced to speed up its metabolic rate, herbs and drugs would be deactivated at a more rapid pace, and the overall effectiveness of ingested substances would be lower. On the other hand, if the liver were made to slow its metabolism, herbs and drugs would be deactivated at a slower pace and the overall impact of the substances would be greater.

In general, drugs that induce greater liver metabolism do not exert an immediate effect. The metabolism rate of the liver changes slowly, over several weeks. Therefore, the effect of accelerated liver metabolism is not seen until weeks after the initiation of drug therapy. Some examples of pharmaceuticals that speed hepatic metabolism are: phenytoin (Dilantin), carbamazepine (Tegretol), phenobarbitals and rifampin (Rifadin). Therefore, herbs given in the presence of one of these products may be deactivated more rapidly, and their overall effectiveness lowered. Under these circumstances, a higher dose of herbs may be required to achieve the desired effect.

In great contrast, drugs that inhibit liver metabolism have an immediate onset of action. The rate of liver metabolism may be greatly impaired within a few days. Pharmaceuticals that slow or inhibit liver metabolism include: cimetidine (Tagamet), erythromycin, ethanol, fluconazole (Diflucan), itraconazole (Sporanox) and ketoconazole (Nizoral), among others. When a patient takes these drugs concurrently with herbs, there is a higher risk of herbal components accumulating in the body, as the ability of the liver to neutralize them is compromised. If the herbs are metabolized more slowly, their overall effectiveness may be prolonged. In this case, one may need to lower the dosage of herbs to avoid unwanted side effects.

Depending on the half-life in the body of drugs that influence liver metabolism, it may be necessary to increase or decrease the dosages of herbs for weeks or even months after discontinuation of the pharmaceutical substance, along with consistent monitoring.

Elimination
While the liver neutralizes incoming drugs and herbs, the kidneys are responsible for eliminating the substances and their metabolites from the body. If the kidneys are damaged, then the rate of elimination is slowed, leading to an accumulation of active substances in the body. Important examples of drugs that damage the kidneys include amphotericin B, methotrexate, tobramycin and gentamicin. As a safety precaution, when prescribing herbs for a patient who is currently taking or has recently taken one of these drugs, it may be wise to lower the dose of herbs to avoid unnecessary and unwanted side effects.

Summary of Pharmacokinetic Interactions
The pharmacokinetic interactions listed above include both theoretical and actual interactions. Though such interactions are possible, the extent and severity of each interaction will vary depending on the specific circumstances, such as the dosages of all substances, the inherent sensitivity of each patient, individual body weight, and metabolic rate.

Summary: Concurrent Use of Herbal Medicines and Pharmaceuticals
Historically, herbs and drugs have been presumed to be very different treatment modalities that have rarely, if ever, been used together. The line that separates the use of herbs and drugs, however, has blurred in recent decades as the lay public gains increased accessibility to multiple treatment modalities. It is not uncommon for one patient to seek care from several health professionals for an ailment. As a result, a patient may easily be taking multiple drugs, herbs, supplements, and vitamins concurrently. It becomes difficult to predict whether the combination of all these substances will lead to unwanted side effects and/or interactions. It is imprudent to assume that there will be no interactions. On the other hand, it is just as unwise to abandon treatment simply for fear of possible interactions. The solution to this situation is in the understanding of pharmacokinetic and pharmacodynamic herb-drug interactions. By understanding these mechanisms, one can recognize potential interactions and take proper actions to prevent their occurrence.

As you might see in my bio, I have been using the theories of neurolinguistic programming in several areas on my practice. One such area is in creating well-formed outcomes. A well-formed outcome asks what the patient will be doing and experiencing when their presenting issue is resolved, and is always stated in the positive. (Rather than “I want to have no more pain,” which focuses on the pain at the subconscious and conscious levels, a well-formed outcome may be, “I will know I am feeling better when I can touch my toes and lift over 20 lbs. comfortably.” A well-formed outcomes informs the mind of an intention in such a way that the unconscious wants to move toward rather than away from something.

When someone is having a difficult time coming up with a well-formed outcome, has some unclear goals, or wants to use hypnosis in a future session, I may have them do a writing assignment to get a well-formed outcome before the next appointment. What follows is one such assignment based on the work of Dave Elman, a well-known hypnotherapist.

What follows is the ‘homework assignment’ I’d like you to do between now and our next meeting. It’s a free-write, and you should set aside 30 minutes to do it in a quiet place with no interruptions.

Start by writing about the outcome you wish to have, and state it in the positive (i.e., “I want to be calm, confident, and clear-headed when….” rather than “I don’t want to be anxious when I….”) Be as specific as possible (i.e., “By June 1, I will feel…, and I will be….”)

Write about how you intend to get there (“…by studying x amount, meditation, etc…”).

Next, write about how you would know you have achieved it. How would it/you look, feel, move…all the physical aspects of the positive end result, as well as the emotional and perhaps spiritual experience. What is your motivation; what benefit will it give you to experience/achieve your desired outcome? You will also want to express the context of your success, quantify it. Where, when, with whom do you want it?

Try to write about your desired outcome for the full 30 minutes. When you are done, read through it and reduce the whole thing–the desired outcome, the way it looks, feels, etc., everything you wrote–reduce it down to a single, simple phrase, as concise as possible to represent it all. It could be as simple as ‘confident, competent’ or a full sentence.

Finally, once you have a concise statement or words representing your desired outcome, create or imagine a simple symbol that represents it all. Draw that picture and visualize it in your mind’s eye. We’ll use that simple, concise statement and its attendant symbol the next time you come in.
