International Desk : Doctors in India are warning against the practice of using cow dung in the belief it will ward off Covid-19, saying there is no scientific evidence for its effectiveness and that it risks spreading other diseases, reports Reuters.

The coronavirus pandemic has wrought devastation on India, with 22.66 million cases and 246,116 deaths reported so far.

Experts say actual numbers could be five to 10 times higher, and citizens across the country are struggling to find hospital beds, oxygen or medicines, leaving many to die for lack of treatment.

In the state of Gujarat in western India, some believers have been going to cow shelters once a week to cover their bodies in cow dung and urine in the hope that it will boost their immunity against, or help them recover from, the coronavirus.

In Hinduism, the cow is a sacred symbol of life and the earth, and for centuries, Hindus have used cow dung to clean their homes and for prayer rituals, believing it has therapeutic and antiseptic properties.

"We see... even doctors come here. Their belief is that this therapy improves their immunity and they can go and tend to patients with no fear," said Mr Gautam Manilal Borisa, an associate manager at a pharmaceuticals company, who said the practice helped him recover from Covid-19 last year.

He has since been a regular at the Shree Swaminarayan Gurukul Vishwavidya Pratishthanam, a school run by Hindu monks that lies just across the road from the Indian headquarters of Zydus Cadila, which is developing its own Covid-19 vaccine.

As participants wait for the dung and urine mixture on their bodies to dry, they hug or honour the cows at the shelter, and practice yoga to boost energy levels. They are then washed off with milk or buttermilk.

Doctors and scientists in India and across the world have repeatedly warned against practising alternative treatments for Covid-19, saying these can lead to a false sense of security and complicate health problems.

"There is no concrete scientific evidence that cow dung or urine works to boost immunity against Covid-19. It is based entirely on belief," said Dr J.A. Jayalal, national president at the Indian Medical Association.

"There are also health risks involved in smearing or consuming these products - other diseases can spread from the animal to humans."

There are also concerns that the practice could contribute to the spread of the virus as it involves people gathering in groups.

Mr Madhucharan Das, who is in charge of another cow shelter in Ahmedabad, said the shelter is limiting the number of participants.
