Vapo rub

VapoRub (usually referring to Vicks VapoRub) is an over-the-counter topical ointment, mainly used for applying to the throat and chest to relieve coughing caused by a cold.
Its main active ingredients are camphor, eucalyptus oil and menthol. The combination of these ingredients can produce volatile medicinal vapors. After applying it, inhaling these vapors can help temporarily relieve coughing caused by mild irritation of the throat and bronchi. Moreover, as camphor and menthol are also local analgesics, VapoRub can also be used to temporarily relieve mild aches in muscles and joints.
Key Considerations and Risks
Although VapoRub is a common household remedy, its use involves some critical risks and precautions. Incorrect usage may lead to serious consequences:
Absolutely prohibited for use in children under 2 years old: Using VapoRub on any part of the body of children under 2 years old is unsafe.
Do not take orally: VapoRub contains camphor. Even a few teaspoons swallowed could cause fatal poisoning in infants. If ingested accidentally, depending on the amount consumed, it may cause symptoms ranging from mild stomach discomfort to seizures.
Do not use inside or around the nostrils: Cinnamon oil can be absorbed through the mucous membranes or damaged skin, which may cause poisoning. Therefore, never apply the ointment inside or around the nostrils, especially not on children.
Avoid contact with eyes: If VapoRub gets into your eyes, it may damage the cornea (the transparent outer layer of the eye).
Explanation on Relieving Nasal Congestion
A common misconception is to use VapoRub to relieve nasal congestion. It is important to note that VapoRub cannot truly cure or alleviate nasal congestion. Its strong minty scent gives people the illusion that their nose is clear, but this is merely a deceptive sensation in the brain, not an actual nasal passage being unclogged. For true nasal congestion, it is recommended to use saline nasal drops, sprays, or use a cold mist humidifier, etc.
In summary, VapoRub is an effective topical medication for alleviating coughs and muscle aches. However, it must be used strictly within the age limits and on the designated application areas. Special attention should be paid to avoiding ingestion and contact with the eyes and nasal passages.
