This is a wonderful tea for those with cold symptoms that seem to linger. Elderberry has been used for centuries to treat respiratory illnesses associated with colds, flus, and infections. Elecampane-with actions that are expectorant, anti fungal, antitussive, and warming-is able to clear congestion in the lungs and lower throat, and is used to treat bronchitis and asthma. Eucalyptus, in tea form, lends a nice menthol character that helps clear mucus blockages. Yerba Santa supports respiratory health and licorice root adds sweetness and is great for soothing sore throats. Lemon balm supports the nervous system and has antiviral properties. Peppermint adds flavor and the aromatic aspect helps to clear sinus congestion and remove excess heat. Marshmallow root is great for soothing inflamed tissues in the mouth and throat, especially if you have a cough.
