Ahh, yes, the Houttuynia tea!! Lovely stuff ...and
very potent! I used Houttuynia for my Bart infection and it worked really well (as far as we can tell at this point anyway!)
When I was starting it, I was told to use 3 grams of the herb to 3 cups of boiling water and drink 1 cup three times a day. Well I started off by using 6 cups of water and couldn't even drink 1 cup without a horrible herx!!!
So I had to only drink 1/2 cup of the diluted tea for three weeks before my herxing would stop! LOL! That's when I learned how much my doc doesn't want me herxing!! LOL! She was kind of upset with me for allowing it to go on like I did!
I don't have any experience with the Sida Acuta though. From your descript
ion it does sound like a herx, but I would assume it's from the Sida Acuta from the timing of it.
