Lung and immune herbal support blend. As the red elderberries are ripening I knew it was about time for black elderberry to flower. I checked on my patch of Sambucus canadensis and they were blooming and beautiful, as was the Mullein, Linden, Eyebright and Peppermint. This herbal tea is a great blend to support the immune system and the respiratory tract as well as the nervous system. Moistening and cooling reducing inflamed mucus membranes and aiding with expelling mucus from the lungs. Cooling and clearing the eyes and soothing the throat.
