evidence: A series of WhatsApp messages and Facebook posts, including one from politician and spokesperson of the BJP, claims Camphor, Ajwain, Lavang (Clove), Eucalyptus Oil helps increase the Oxygen level in the body. We investigated and found that the message is False. The message in circulation reads – "Camphor, lavang, ajwain, few drops 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." [...] However, multiple trekkers confirmed that they carry a small pack of Camphor when they go out to trek. Camphor is known to keep the nasal passage open which helps in proper inhalation in high altitude where Oxygen levels are lower.
