Blending nationalism and pseudoscience, the “cures” touted by an Indian ministry are raising public health concerns.

When it was announced in late March that Prince Charles, heir to the British throne, was well on his way to recovering from Covid-19, there was some celebration 4,000 miles away in India, a former British colony. But it was not colonial nostalgia that brought on the cheer, so much as the declaration a few days later by an Indian government minister that the Prince of Wales had been cured using Ayurveda — a blend of, among other things, herbal medicine, breathing exercises, and meditation.

At an April 2 press conference, Shripad Naik, India’s minister for alternative medicines, declared that the treatment’s supposed success “validates our age-old practice.” The British government swiftly issued a statement rejecting his claim. “This information is incorrect. The Prince of Wales followed the medical advice of the National Health Service in the U.K. and nothing more,” a spokesperson said the following day.

But this hasn’t deterred Naik’s Ministry of Ayurveda, Yoga & Naturopathy, Unani, Siddha, and Homeopathy — or AYUSH for short — from promoting Indian alternative medicines as treatments for Covid-19. Established in 2014, the goal of AYUSH is to develop and popularize these treatments, many of which have their historical roots in India. Ayurveda, for example, has been practiced in India for thousands of years.

Now, Naik said, the ministry aims to confirm that Prince Charles was cured using a combination of Ayurveda and the pseudoscience known as homeopathy, which has its roots in Germany, so that the treatment can be rolled out to the masses. This is in stark contrast to the position of mainstream medicine, which has not yet confirmed any evidence-based medicine for Covid-19, and is still highly cautious of giving experimental drugs to patients.

And yet for many, the actions of the right-wing Indian government don’t come as a surprise. Aside from the popularity of alternative medicine in India generally, the ruling Bharatiya Janata Party (BJP) is known for supporting Hindutva, a form of nationalism that seeks to transform India from being a secular nation into an openly Hindu one. This partly plays out in the field of health, where alternative therapies that have their roots in India, such as Ayurveda, are considered more “Hindu” or “Indian” than modern medicine. Supporting them becomes an opportunity to push forward this nationalist agenda.

In the early days of the epidemic, AYUSH heavily promoted therapies that lack an evidence base, said Sumaiya Shaikh, a neuroscientist based at the Center for Social and Affective Neuroscience at Linköping University Hospital in Sweden. Shaikh is also editor of science at Alt News, an Indian website that works to expose misinformation.

Examples of treatments pushed by AYUSH included a homeopathic medicine containing diluted arsenic, an Ayurvedic drug developed by the ministry to treat malaria, and dietary changes including drinking warm water, putting sesame oil inside the nose, or consuming holy basil, ginger, cloves, and turmeric. The ministry suggested these interventions could prevent people from developing Covid-19 as well as treat its symptoms.

“There was some amount of criticism to that,” said Shaikh. And so in response, the ministry provided a list of “scientific evidence” to bolster its claims. Aside from the fact that homeopathy has been repeatedly shown to have no biological effects, Shaikh said that when she and her team reviewed the list, the only actual research they could find was one analysis that examined the the same homeopathic treatment in bovines with gastric infections. Despite this, the ministry’s promotion of the therapy increased demand in many Indian states.

This isn’t the first time the ministry has faced criticism for promoting unscientific claims or backing research derived from religious myths and beliefs. One of its repeated focuses has been cow urine, which is believed by many Hindus to have healing properties given the sacred nature of cows in Hinduism. The urine has been touted as a treatment for many illnesses, including diabetes, epilepsy, and AIDS. Naik himself has made several comments in parliament about how cow urine can cure cancer. In reality, its use can be dangerous.

In fact, so widespread is the belief in cow urine that on March 17, an activist working for the BJP in Kolkata organized a “gomutra (cow urine) party” to ward off Covid-19. He believed that drinking the urine would protect them from the disease. Unfortunately, one of the volunteers fell seriously ill after ingesting the urine.

The Ministry of AYUSH’s research portal carries papers on the uses of panchagavya, the five products derived from a cow, of which urine is one, supporting its use as a medical product. However, Ipsita Mohanty, who co-wrote a paper listed there titled “Diversified Uses of Cow Urine,” said in an email that she couldn’t definitively answer whether cow urine fights off Covid-19, as “it has not been proven by independent researchers.”

This reflects how AYUSH researchers and doctors seek validation, explained Shaikh. “If a paper gets published anywhere — doesn’t matter what type of journal it is or how bad the statistics are — they take it as scientific proof,” she said, adding that the alternative medicine community also has a lot of journals of its own. These are regulated and edited by the same people who are published in them, Shaikh said.

Despite being an advocate of cow urine, Mohanty urges doctors to not spread misinformation. “It is misleading to spread the rumor about something so important when more than half of our world is engulfed by Covid-19,” she said. “There is no vaccine nor any treatment for it. At this point, promoting cow urine against Covid-19 can be very fatal, as people might resort to it for treatment as their only hope.”

The Ministry of AYUSH did not respond to requests for comments from Undark.

“Practitioners of such therapies get their clientele from two distinct groups,” said Aniket Sule, a science education researcher and astronomer at the Homi Bhabha Center for Science Education. He is part of a steadily growing rationalist movement in India that is encouraging dialogue and critical thinking to counter misinformation, including within the realm of alternative medicine.

The first group Sule identified is patients from impoverished communities and remote villages, “who don’t have access to doctors prescribing modern medicines.” The other set of clients is the “affluent and educated class in the cities, who have read half-baked internet posts and develop strong skepticism towards modern medicines,” he said.

“Pushing such a narrative to gullible masses is akin to actively spreading misinformation, and senior functionaries of government should take strict action against such baseless propaganda,” he urged.

The ministry has faced some institutional backlash. The Press Council of India, the statutory body responsible for maintaining good media standards, has issued an order asking print media to stop publicity and advertisements of AYUSH-related claims for Covid-19 treatments.

But despite that, the Ministry of AYUSH continues not only to receive political backing but also a large share of the annual health budget. From 2019 to 2020, the Indian government allotted approximately $250 million for study and promotion of alternative medicines, a 15 percent increase from the previous year. According to Shaikh, only the defense ministry saw a larger proportional increase to its budget last year.

Indian scientists fighting disinformation say there is an underlying nationalist agenda to this move. Certain radical groups affiliated with the government have dreams of spreading Hindu values beyond India’s borders to create an “Akhand Bharat,” or “consolidated Hindu nation,” which would include annexing a large part of the Indian subcontinent. One of these is Rashtriya Swayamsevak Sangh, a militant organization that has a long history of promoting Hindutva. Its leader recently said that Ayurveda is part of India’s “soft power” in the South Asian region, said Shaikh.

The Press Council of India, the statutory body responsible for maintaining good media standards, has issued an order asking print media to stop publicity and advertisements of AYUSH-related claims for Covid-19 treatments.

Since coming to power in 2014, India’s current government (BJP) has increasingly backed divisive policies that consolidate the power of the majoritarian Hindu population. “Overall, this government has made virtue out of extreme and thoughtless nationalism. Increased support to all these questionable therapies is a natural byproduct of that,” Sule said, adding there is also a distinct motivation among many people who believe in these claims. “There are people who are so completely blinded by ‘glorious ancient India’ that they willingly walk into any trap if it is presented as ‘this is what our great ancestors did,’” he said.

Sule also thinks that AYUSH exists, in part, to protect commercial interests. There are nearly 800,000 practitioners of alternative medicine in India, he said, and over 650 colleges teaching related courses. The Ayurveda industry alone in India is worth $4.4 billion and is expected to grow by 16 percent in the next five years.

Shaikh, Sule, and others have been critical of the Ministry of AYUSH for years, exposing and unmasking its questionable research and dubious medical advice. “It is very dangerous, especially now. We are the only country that has a parallel ministry for alternative systems,” Shaikh said. “Why not just have the one ministry and then have everything under it? Use whatever herbs you want, but run them through appropriate trials, and if they work then they should be in the mainstream and everybody should benefit from them,” she said.

Shaikh doesn’t call for closing the ministry but insists the way it works needs to change.

“Don’t start with a belief system, start with the hypothesis,” she advised. “Don’t start with the basis that this drug is going to work. Start with realizing that ‘we don’t know and we want to find out.’ That is unbiased research.”

Many experts say that statements like Naik’s are false and dangerous, particularly now that the country is struggling to control the spread of the novel coronavirus, SARS-CoV-2, among its 1.35 billion people. With a lack of testing and a shortage of physicians, many experts feel the Indian government is failing its people by directing attention and resources to unsubstantiated and unscientific practices — especially when these practices themselves can be harmful.

The more we learn about yoga, the more we realize the benefits aren’t all in the minds of the 20 million or so devotees in the U.S. Yoga helps people to relax, making the heart rate go down, which is great for those with high blood pressure. The poses help increase flexibility and strength, bringing relief to back pain sufferers.

Now, in the largest study of yoga that used biological measures to assess results, it seems that those meditative sun salutations and downward dog poses can reduce inflammation, the body’s way of reacting to injury or irritation.

That’s important because inflammation is associated with chronic diseases including heart disease, diabetes, and arthritis. It’s also one of the reasons that cancer survivors commonly feel fatigue for months, even years, following treatment.

Researchers looked at 200 breast cancer survivors who had not practiced yoga before. Half the group continued to ignore yoga, while the other half received twice-weekly, 90-minute classes for 12 weeks, with take-home DVDs and encouragement to practice at home.

According to the study, which was led by Janice Kiecolt-Glaser, professor of psychiatry and psychology at Ohio State University, and published in the Journal of Clinical Oncology, the group that had practiced yoga reported less fatigue and higher levels of vitality three months after treatment had ended.

Laboratory Proof

But the study didn’t rely only on self-reports. Kiecolt-Glaser’s husband and research partner, Ronald Glaser of the university’s department of molecular virology, immunology, and medical genetics, went for stronger, laboratory proof. He examined three cytokines, proteins in the blood that are markers for inflammation.

Blood tests before and after the trial showed that, after three months of yoga practice, all three markers for inflammation were lower by 10 to 15 percent. That part of the study offered some rare biological evidence of the benefits of yoga in a large trial that went beyond people’s own reports of how they feel.

No one knows exactly how yoga might reduce inflammation in breast cancer survivors, but Kiecolt-Glaser lays out some research-based suggestions. Cancer treatment often leaves patients with high levels of stress and fatigue, and an inability to sleep well. “Poor sleep fuels fatigue, and fatigue fuels inflammation,” she says. Yoga has been shown to reduce stress and help people sleep better.

Other smaller studies have shown, by measuring biological markers, that expert yoga practitioners had lower inflammatory responses to stress than novice yoga practitioners did; that yoga reduces inflammation in heart failure patients; and that yoga can improve crucial levels of glucose and insulin in patients with diabetes.

Yoga for Other Stresses

Cancer is an obvious cause of stress, but recent research has pointed to another contributing factor: living in poverty. Maryanna Klatt, an associate professor of clinical family medicine at Ohio State University, has taken yoga into the classrooms of disadvantaged children. In research that has not yet been published, she found that 160 third graders in low-income areas who practiced yoga with their teacher had self-reported improvements in attention.

“Their teachers liked doing it right before math, because then the kids focused better on the math work,” she says. “Telling a kid to sit down and be quiet doesn’t make sense. Have them get up and move.”

While it would be too complicated and intrusive to measure biological responses to yoga in schoolchildren, Klatt has done similar research on surgical nurses, who are under the daily stress of watching suffering and death. She said she found a 40 percent reduction in their salivary alpha amylase, a measure of the fight-or-flight response to stress.

And she’s about to begin teaching yoga to garbage collectors in the city of Columbus before they head out on their morning shift. At the moment, her arrangement with the city is not part of a study. She just hopes to make their lives less stressful. And she does not plan to check their inflammatory response, though she admits she’d love to.

Mind Over Matter? Core Body Temperature Controlled by the Brain (Science Daily)

Apr. 8, 2013 — A team of researchers led by Associate Professor Maria Kozhevnikov from the Department of Psychology at the National University of Singapore (NUS) Faculty of Arts and Social Sciences showed, for the first time, that it is possible for core body temperature to be controlled by the brain. The scientists found that core body temperature increases can be achieved using certain meditation techniques (g-tummo) which could help in boosting immunity to fight infectious diseases or immunodeficiency.

Published in science journal PLOS ONE in March 2013, the study documented reliable core body temperature increases for the first time in Tibetan nuns practising g-tummo meditation. Previous studies on g-tummo meditators showed only increases in peripheral body temperature in the fingers and toes. The g-tummo meditative practice controls “inner energy” and is considered by Tibetan practitioners as one of the most sacred spiritual practices in the region. Monasteries maintaining g-tummo traditions are very rare and are mostly located in the remote areas of eastern Tibet.

The researchers collected data during the unique ceremony in Tibet, where nuns were able to raise their core body temperature and dry up wet sheets wrapped around their bodies in the cold Himalayan weather (-25 degree Celsius) while meditating. Using electroencephalography (EEG) recordings and temperature measures, the team observed increases in core body temperature up to 38.3 degree Celsius. A second study was conducted with Western participants who used a breathing technique of the g-tummo meditative practice and they were also able to increase their core body temperature, within limits.

Applications of the research findings

The findings from the study showed that specific aspects of the meditation techniques can be used by non-meditators to regulate their body temperature through breathing and mental imagery. The techniques could potentially allow practitioners to adapt to and function in cold environments, improve resistance to infections, boost cognitive performance by speeding up response time and reduce performance problems associated with decreased body temperature.

The two aspects of g-tummo meditation that lead to temperature increases are “vase breath” and concentrative visualisation. “Vase breath” is a specific breathing technique which causes thermogenesis, which is a process of heat production. The other technique, concentrative visualisation, involves focusing on a mental imagery of flames along the spinal cord in order to prevent heat losses. Both techniques work in conjunction leading to elevated temperatures up to the moderate fever zone.

Assoc Prof Kozhevnikov explained, “Practicing vase breathing alone is a safe technique to regulate core body temperature in a normal range. The participants whom I taught this technique to were able to elevate their body temperature, within limits, and reported feeling more energised and focused. With further research, non-Tibetan meditators could use vase breathing to improve their health and regulate cognitive performance.”

Further research into controlling body temperature

Assoc Prof Kozhevnikov will continue to explore the effects of guided imagery on neurocognitive and physiological aspects. She is currently training a group of people to regulate their body temperature using vase breathing, which has potential applications in the field of medicine. Furthermore, the use of guided mental imagery in conjunction with vase breathing may lead to higher body temperature increases and better health.
