Steam is a simple method for treating cough and congestion. It loosens phlegm, moisturizes the throat, and clears nasal passages. Adding essential oils to a steam bath can incorporate the anti-inflammatory and anti-bacterial properties of some oils, though this should be done with care, as strong vapors could cause more issues.
Simply boil water and let it cool slightly. Pour it into a bowl, add a drop of eucalyptus or tea tree oil, and place your face over the bowl with a towel over your head.
