Camphor Oil What Is Camphor Oil? Did you know that camphor is the most significant ingredient in Vick's Vapour Rub – a mentholated salve that's been around for over 125 years? Indeed, camphor has been used in folk medicine for centuries and was even used in ancient Sumatra to treat sprains, swellings, and inflammation. It was also used extensively in Europe between 1347 and 1351 to combat Black Death (or the Plague). Today it is used above and beyond anything else as a powerful decongestant and for respiratory system support. https://www.nationalnutrition.ca/aromatherapy-essential-oils/single-essential-oils/camphor-oil.html #Aromatherapy
