Sometimes simple is good A few months ago, I experienced a lingering cough after an case of influenza. When it was a stronger, more irritating cough, I treated it aggressively with Planetary Formulas’ Old Indian Wild Cherry Syrup (plus other things). It’s strong stuff, but when I have had bronchial infections it has historically helped so much that I go straight to it. After the worst of the cough was gone, I reached for a tea of three simple herbs which are easy to harvest and created a tea general tea for the lungs that’s quite delicious. Three Herb Tea for Promoting General Lung Function Mullein – Verbascum thapsus. Red Cedar –Thuja plicata. Dried Tangerine Peel – Citrus tangerina.
