evidence: The core content of the message says, "Camphor, lavang, ajwain, few drops of eucalyptus oil. Make a potli and keep smelling it throughout the day and night. Helps increase oxygen levels and congestion. This potli is also given to tourists in Ladakh when oxygen levels are low. Many ambulances are now keeping these too. It's a home remedy. Kindly share and help (sic)." [...] Similarly, lavang (clove) mentioned in the camphor potli is not known for improving oxygenation in the body. It has its medicinal value and a study talked about its potential for being used in Covid-19 treatment citing previous instances of cloves having anti-viral properties. But even this study does not claim that cloves can improve oxygen levels in the body. Ajwain (carom seeds) or eucalyptus oil are again used in traditional medicines and some chemical drugs, but there is no study to suggest that they improve oxygen levels among patients suffering from respiratory illnesses in general and Covid-19 in particular.
