evidence: There is no scientific evidence to prove that a combination of camphor, cloves, carom seeds and a few drops of eucalyptus oil can help in increasing oxygen levels in the body. Social media posts and YouTube videos promoting a combination of products available at home to help increase oxygen levels in the body are getting wide popularity. However, the claim is false. We came across 7-8 YouTube videos claiming that inhaling vapours of camphor (kapur), clove (laung), carom seeds (ajwain) and eucalyptus oil can increase the blood oxygen level. In some videos, this claim is also being attributed to doctors and medical institutions.
