evidence: India breached the 3 lakh cases a day mark last week, and people have been prompt to circulate balderdash home remedies and techniques for COVID-19 patients in home isolation. The latest fad is promoting the use of camphor, eucalyptus oil and neem while doing steam inhalation. The WhatsApp message doing the rounds suggests making a small potli (bag) consisting of camphor, ajwain (carom seeds) laung (cloves) and a few drops of eucalyptus oil. The message claims that when this mix is inhaled it helps in "increasing the oxygen levels" in the body. [...] Do note that on the contrary, inhaling the mixture of camphor can lead to camphor poisoning, which in some cases is life-threatening. In patients who are COVID-19 positive, the blood oxygen saturation decreases because of the viral infection of the lungs and lower respiratory tract damage. It has little to do with nasal blockage and therefore relieving the nasal obstruction does not lead to an improved oxygen saturation level.
