I purchased this awesome tincture from Blue Mountain Tea Co. with raving reviews from Cathy the owner - and I certainly was not disappointed. I purchased it in hopes it would help shorten my fast developing chest cold, and it lived up to the hype. I found it helped with my daily energy level. I continued use afterwards once a week. I simply added the recommended dose to my beverage of choice, nor was the taste unpleasant. Thank you Cathy for your recommendation!
