This tea will kill whatever ails you. I’ve been using this tea since I was in college (early to mid-80’s) and whenever I get sick, this is my go-to fix. According to other sources, Pau d’Arco is supposed to be an anti-viral, anti-bacterial, and anti-fungal herb. I have found it works, particularly on very bad chest colds and bronchitis. The flavor is earthy and somewhat astringent, but not unpleasant. I find adding 1/2 organic lemon to it makes it quite good. My rating goes to its effectiveness and apparent quality, not necessarily its flavor. I always steep this tea according to directions, which is 15 minutes.
