Boris Johnson has recently bent over backward in order to please the Indian PM, Narendra Mondi. Some even say that a trade agreement between the two countries was achieved at the cost of letting the Delta variant into the UK. Now it seems that political considerations are at the heart of the decision to lend official support to Indian traditional medicine in the UK. The ‘2030 Roadmap for India-UK future relations‘ is a policy document of the UK government. In it, we find that the UK government intends to:

  • Explore cooperation on research into Ayurveda and promote yoga in the UK.
  • Increase opportunities for generic medicine supply from India to the UK by seeking access for Indian pharma products to the NHS and recognition of Indian generic and Ayurvedic medicines that meet UK regulatory standards.

This clearly begs the question, are these plans good or bad for UK public health?

Ayurveda is a system of healthcare developed in India around the mid-first millennium BCE. Ayurvedic medicine involves a range of techniques, including meditation, physical exercises, nutrition, relaxation, massage, and medication. Ayurvedic medicine thrives for balance and claims that the suppression of natural urges leads to illness. Emphasis is placed on moderation. Ayurvedic medicines are extremely varied. They usually are mixtures of multiple ingredients and can consist of plants, animal products, and minerals. They often also contain toxic substances, such as heavy metals which are deliberately added in the ancient belief that they can have positive health effects. The truth, however, is that they can cause serious adverse effects.

Relatively few studies of Ayurvedic remedies exist and most are methodologically weak. A Cochrane review, for instance, concluded that” although there were significant glucose-lowering effects with the use of some herbal mixtures, due to methodological deficiencies and small sample sizes we are unable to draw any definite conclusions regarding their efficacy. Though no significant adverse events were reported, there is insufficient evidence at present to recommend the use of these interventions in routine clinical practice and further studies are needed.”

The efficacy of Ayurvedic remedies obviously depends on the exact nature of the ingredients. Generalizations are therefore problematic. Promising findings exist for a relatively small number of ingredients, including Boswellia, Frankincense, Andrographis paniculata.

Yoga has been defined in several different ways in the various Indian philosophical and religious traditions. From the perspective of alternative medicine, it is a practice of gentle stretching exercises, breathing control, meditation, and lifestyles. The aim is to strengthen prana, the vital force as understood in traditional Indian medicine. Thus, it is claimed to be helpful for most conditions affecting mankind. Most people who practice yoga in the West practise ‘Hatha yoga’, which includes postural exercises (asanas), breath control (pranayama), and meditation (dhyana). It is claimed that these techniques bring an individual to a state of perfect health, stillness, and heightened awareness. Other alleged benefits of regular yoga practice include suppleness, muscular strength, feelings of well-being, reduction of sympathetic drive, pain control, and longevity. Yogic breathing exercises are said to reduce muscular spasms, expand available lung capacity and thus alleviate the symptoms of asthma and other respiratory conditions.

There have been numerous clinical trials of various yoga techniques. They tend to suffer from poor study design and incomplete reporting. Their results are therefore not always reliable. Several systematic reviews have summarised the findings of these studies. An overview included 21 systematic reviews relating to a wide range of conditions. Nine systematic reviews arrived at positive conclusions, but many were associated with a high risk of bias. Unanimously positive evidence emerged only for depression and cardiovascular risk reduction (Ernst E, Lee MS: Focus on Alternative and Complementary Therapies Volume 15(4) December 2010 274–27).

Yoga is generally considered to be safe. However, the only large-scale survey specifically addressing the question of adverse effects found that approximately 30% of yoga class attendees had experienced some type of adverse event. Although the majority had mild symptoms, the survey results indicated that attendees with chronic diseases were more likely to experience adverse events associated with their disease. Therefore, special attention is necessary when yoga is introduced to patients with stress-related, chronic diseases. 

So, should we be pleased about the UK government’s plan to promote Ayurveda and yoga? In view of the mixed and inconclusive evidence, I feel that a cautious approach would be wise. Research into these subjects could be a good idea, particularly if it were aimed at finding out what the exact risks are. Whole-sale integration does, however, not seem prudent at this stage. In other words, let’s find out what generates more good than harm for which conditions and subsequently consider adopting those elements that fulfill this vital criterium.

2 Responses to Our government plans to promote Ayurveda and yoga in the UK

  • Reasonable ideals:

    1. “Explore cooperation on research into Ayurveda…”
    Shouldn’t take long.
    All the Ayurvedic practitioners have to do is show that their methods have worthwhile, reproducible effects beyond the placebo.
    Up them to give evidence of that.

    2. “… and promote yoga in the UK.”
    Hang on.
    The government must not conflate ‘Ayurveda’ with yoga.
    Same consideration applies: Demonstrate Yoga does better than any other placebo.

    3. “Increase opportunities for generic medicine supply from India to the UK by seeking access for Indian pharma products to the NHS”.
    No problem if our standards are met.
    We already receive many pharmaceuticals from India, including vaccines made there.
    No problem – if they meet UK standards.

    “… and recognition of Indian generic and Ayurvedic medicines that meet UK regulatory standards.”
    Well yes, OK.
    But none do, or are ever likely to. That’s the point.

    The government must stop conflating commercial interests with modern medicine.
    It is that attitude which has allowed a mindset in which vaccine hesitancy thrives.

    Why should UK doctors and scientists take the government seriously if the government cannot be bothered to take science seriously.

    Sigh.

    • They want to introduce Ayurvedic medicines in the UK health system? Then I’d say that these ‘medicines’ should comply with at least the same of the following regulations as real medicines:
      – Clinically proven efficacy
      – Proven safety

      (and oh, the name is Narendra Modi, so no ‘n’ in the last name)
