A Natural Way – Traditional Medicine and Natural Healing

A Natural Way – Traditional Medicine and Natural Healing

Directed by Josh Bradley (2011)

Film Review

This documentary explores the history of Eastern medicine, with a primary focus on Indian, Tibetan, and Chinese traditional medicine. All three put primary emphasis on restoring balance (between Yin and Yang and the five elements of earth, fire, water, wind, and space). The epidemic of chronic illnesses with no known Western cure has sparked a large interest in Eastern medicine throughout the industrial world.

In India yoga, mediation, and controlled breathing heal via restoring mental balance. In contrast, Indian Ayruvedic medicine uses diet and herbs to restore the body’s free flow of prana or life energy (known as chi or qi in Chinese medicine).

Tibetan medicine, which traces its origin to India and Buddhism, is also based on restoring free flow of prana. A Tibetan practitioner diagnoses the specific imbalance by questioning patients about their symptoms and diet and examining pulses their (for 60+ factors) and tongue. Treatment consists mainly of herbs grown in the high Tibetan Himalayas, though some herbs are imported from Chinese and Indian lowlands.

The vast majority of the film is devoted to Chinese medicine, which has the longest recorded history. The first Chinese medical textbook, The Yellow Emperor Inner Cannon, appeared in the first century BC. Its remedies rely on a vast array of herbs, insects, and animal parts.*

Chinese medicine also boasts a variety of healing disciplines, including “bonesetting,” which exerts heavy pressure on acupuncture points to relieve musculoskeletal pain; acupuncture, which employs needles and “cupping” at acupuncture points to establish free flow of chi; Tai Chi, a practice derived from the martial art Qigong that uses controlled breathing and slow coordinated movements to unblock chi; and daoyin, a more refined form of Tao Chi which is more effective for specific symptom relief.

The film includes a visit to two acupuncture clinics, and a large factory that mass produces herbal remedies for domestic use and global export.


*Including bat shit. Since China made them a protected species, bat body parts are no longer used as remedies. However according to filmmakers, their poo works just as well.

**Cupping is a form of traditional Chinese medicine that places warm suction cups on key acupuncture points.

Mainstreaming Natural Health Care

(This is the 3rd of four posts on the effectiveness of “natural” or “alternative” health care.)

Third Party Coverage

Presently Germany, which has publicly guaranteed health care for all its citizens, is the only country to offer “natural” health care on a par with western medicine. However even in the US, where most health care funding is private, an increasing number of insurance companies offer coverage for “natural” or “alternative” health care. There is usually a requirement these services be offered in conjunction with traditional or “allopathic” care. The jargon used for these mixed mainstream-alternative health models is “complementary” or “integrative” medicine. Most insurance companies require that complementary and alternative medicine (CAM) providers be represented by a professional body with a formal accreditation process. There is also an expectation 1) that the accreditation body will establish clear treatment standards and 2) that all funding will be evidence and outcome-based. In other words, CAM providers must demonstrate a treatment actually works to be eligible for funding.

Some analysts are projecting that insurance coverage for natural health care will be even easier to access under Obamacare – at least for patients who can afford the higher premiums of silver, gold, and platinum plans. The uninsured and patients locked into Medicaid or bare bones bronze plans will be out of luck.

Natural Health Databases

The requirement for natural health services to be “evidence based” has led to the creation of a number of natural health research databases. Three of the most popular are the Mayo Clinic Alternative Medicine database, the NIH Complementary and Alternative Medicine database, and the Cochrane Complementary Medicine database.

The Mayo Clinic is a world famous “mainstream” medical center in Minnesota. Their database is by far the most comprehensive and user-friendly. The following statement on their home page summarises their philosophy:

“Exactly what’s considered complementary and alternative changes constantly as treatments undergo testing and move into the mainstream.”

The site provides up-to-date research summaries on a broad range of alternative treatment approaches. For example, here is what they have to say about aromatherapy:

Research on the effectiveness of aromatherapy — the therapeutic use of essential oils extracted from plants — is limited. However, some studies have shown that aromatherapy might have health benefits, including:

  • Relief from anxiety and depression
  • Improved quality of life, particularly for people who have chronic health conditions

Essential oils used in aromatherapy are typically extracted from various parts of plants and then distilled. The highly concentrated oils may be inhaled directly or indirectly or applied to the skin through massage, lotions or bath salts. Aromatherapy is thought to work by stimulating smell receptors in the nose, which then send messages through the nervous system to the limbic system — the part of the brain that controls emotions.

Many essential oils have been shown to be safe when used as directed. However, essential oils used in aromatherapy aren’t regulated by the Food and Drug Administration. When applied to the skin, side effects may include allergic reactions, skin irritation and sun sensitivity. In addition, further research is needed to determine how essential oils might affect children and how the oils might affect women who are pregnant or breast-feeding, as well as how the oils might interact with medications and other treatments.

I find the NIH and Cochrane databases less helpful. Both seem quite biased towards mainstream medicine and randomized controlled trials (RCTs). Many alternative treatment methods don’t lend themselves to RCTs because it’s virtually impossible to provide “sham” treatment (e.g. sham acupuncture, cupping, or aromotherapy) for the placebo group. Both NIH and Cochrane ignore the abundance of crossover design CAM studies in which the patient serves as their own control. In these studies, treatment is withdrawn once a clear response is established. It’s then reintroduced when symptoms recur.

How Natural Health Care Affects Genes

 (This is the 2nd of 4 posts regarding the effectiveness of “natural” or “alternative” health care.)

The Wall Street Journal article I mentioned in my last post also mentions other research into the mechanism by which plant-based diets, yoga, and meditation halt or even reverse the progression of prostate cancer, heart disease, diabetes, hypertension, and other chronic conditions. One study, published in the Proceedings of the National Academy of Science, provides evidence that only a few months of similar “natural” treatments permanently alters gene expression. It describes how genes associated with cancer, heart disease, and inflammation were downregulated or “turned off,” while protective genes were upregulated or “turned on.” Another study published in The Lancet Oncology reported that these changes also increased telomerase, the enzyme that lengthens the telomeres at the ends of our chromosomes. Telomeres control how long we live. No prescription medication has ever been shown to do this.

Popularity of Natural Health Care

A recent Discovery Channel special revealed that 40% of Americans employ use some form of “natural” medicine. At their website, they list the ten most common, in order of popularity, along with general comments about documented benefits and potential risks:

1. Natural supplements and herbal medicines – benefits best supported by research evidence include omega 3 for heart disease, arthritis, and depression; garlic for cholesterol reduction; and ginseng for heart disease. In the US, quality control can be a major issue with natural and herbal supplements, as they aren’t regulated and may contain heavy metals and other toxins. In New Zealand, the Natural Health and Supplementary Products Bill (awaiting its third reading) would establish standards for quality, strength, and purity.

2. Acupuncture – has the strongest evidence base, not only for pain relief, but to improve immunity and alleviate a range of chronic conditions. These are summarised in a recent  World Health Organisation report. Some of the most common conditions that respond to acupuncture include rhinitis* (works better than antihistamines), sinusitis, asthma, irritable syndrome, hypertension, obesity, high cholesterol, menstrual cramps, migraine, menopausal symptoms, and stroke recovery (restores limb function).

3. Spinal manipulation (chiropractic) – also has a growing evidence base of effectiveness in chronic pain and other chronic illnesses.

4. Meditation – research supports effectiveness in treatment of anxiety, depression, and chronic pain.

5. Therapeutic massage – strong evidence base for therapeutic benefit in cancer, HIV, fibromyalgia, and other chronic pain conditions.

6. Ayurveda – an ancient Indian method of healing which shows promise as a way to boost memory and focus, though research into this approach is extremely limited. Some supplements used in this approach can contain heavy metals or cause dangerous interactions with prescription medication.

7. Guided imagery – demonstrated effectiveness in depression, anxiety, and pain.

8. Yoga – studies show that regular yoga practice reduces stress, eases depression, helps control high blood pressure and diabetes symptoms, helps reduce inflammation and asthma symptoms, reduce back pain, and improve heart function.

9. Hypnosis –  shows promise for stress relief, pain management, headaches, dental pain and childbirth.

10. Homeopathy – very limited research base because the individualized treatments used make it hard to generate meaningful statistics.

Natural Health Care: the Research Evidence

Politics Masquerading as Science

(This is the 1st of four posts on the effectiveness of “natural” or “alternative” health care.)

I find it ironic how eager mainstream doctors are to condemn natural health treatments for not being “evidence-based.” Especially when Western medicine can produce little or no scientific evidence regarding the long term effectiveness and safety of many of their treatments. This is particularly true of heart surgery and immunization protocols. We operate on hearts and vaccinate kids for reasons that have nothing to do with scientific evidence. At the same time, we hold “natural” or “alternative” health providers to a much higher standard of proof. This is for complex political reasons that have given organized medicine and Big Pharma a virtual monopoly over health and healing. It has nothing to do with science.

The Myth of Evidence-Based Medicine

Doctors seem to forget that most common Western remedies were incorporated into the medical armamentarium centuries ago without any “proof” whatsoever of their effectiveness or safety. There were no randomized controlled trials when doctors began using digitalis for heart failure, morphine for pain, or sudafed for nasal congestion. All, like many other drugs, are plant-based treatments* originally used by midwives and herbalists (women the Catholic Church condemned as “witches”).

It was only when pharmaceutical companies began to develop synthetics substitutes that drugs were subjected to randomized control trials. Likewise, the long term outcome of many surgical interventions is never studied before they are rushed into the marketplace. A recent Wall Street Journal article examines the cost effectiveness of two common cardiac procedures – coronary angioplasty and coronary bypass surgery.

According to the article, in 2006 American surgeons performed 1.3 million coronary angioplasties at an average cost of $48,399 each – at a total cost of more than $60 billion. The same year they performed 448,000 coronary bypass operations at a cost of $99,743 each – at a total of more than $44 billion.

Despite these costs, a randomized controlled trial published in the New England Journal of Medicine found that angioplasties and stents don’t prolong life or even prevent heart attacks in stable patients (i.e. 95% of patients who receive them). Likewise coronary bypass surgery prolongs life in less than 3% of cases.

The Bias Against Natural Health Care

The authors ask:  Why do Medicare and health insurance companies pay billions of dollars for dangerous, expensive, and largely ineffective heart surgeries – yet balk at paying for “natural” approaches that have proven to reverse and prevent the chronic diseases that account for at least 75% of health care costs (INTERHEART study, The Lancet, Sept 2004)?

Good question.

*Below are just a few common medicines based on ancient plant-based treatments:
