I am interested to know what brand of pau d'arco tea your husband uses, or where you buy it. I love Pau d'arco, but I keep reading that you have to spend a whole lot of money to be sure you are getting the genuine article. I have used (and love) Wisdom Naturals (Wisdom of the ancients) pau d'arco, and also Prince Imports pau d'arco, but I am wondering if Mountain Rose Herbs pau d'arco is also good. Mountain Rose sells for about $4.00 a pound, while Wisdom Naturals works out to about $36.00 a pound, Prince Tea costs about $20.00 a pound. I use a lot of this tea, it is good for my arthritis, helps keep me calm and centered, I can feel an improvement in my heart, and I also had a pain in my right flank that felt like something was growing that was attached to some organ back there, it caused pain whenever I twisted or sat up in bed, and now this is gone, after about 2 months of drinking tons of tea. I don't know what it was because I could not afford to go to the doctor (no insurance, low monthly income)so I am thrilled it is gone. Please--someone--tell me your opinion of mountain rose herbs pau d'arco. Did it verifiably help you? Thanks.
