evidence: One such viral post that has taken over the internet is that inhaling a combination of camphor, cloves (laung), carrom seeds (ajwain) and a few drops of eucalyptus oil can help in increasing oxygen levels in the body. It was also said that this potli is also given to tourists in Ladakh when oxygen levels are low. Many ambulances are also keeping these too.

According to the study, there are no proofs that the use of camphor and other products can alleviate oxygen levels. Some old research has found that camphor and eucalyptus have no effect on nozzle congestion. Therefore, the claim is false and we should not believe in the fake trends that are being circulated. In these crucial times, each one of us should live responsibly.
