Advice & Tips: I made this into a tea by boiling it on the stove and straining it into a mug. I took this herb for approximately 6-8 months & while I was drinking it, I noticed reduced swelling in affected joints. This herb should be available in your local health foods store, if you don't find it, ask and they will usually order some. I was able to do a little more some days while I was on this herb, the pains were a little better some days as well. The only reason I stopped it, was because I developed stomach and bowl cramping and some diarrhea & only slight nausea...no vomiting. Do your research before starting this herb & be aware that it contains Aspirin in its base form so if you are on any OTC or Prescription NSAID's, be careful and most important, talk to your dr before you start or while you are taking this herb. Be sure you tell him how much you are taking as well, I did. Good Luck!
