I'm not sure about my thyroid these days. It was slightly low the last time I checked about a year ago, but my temps are stable now and were all over the place back then. It wouldn't matter if it were low anyways, because there is no way in hell that I would supplement thyroid again.
Anyhow, I used to take pau d'arco for Candida. In fact I had a severe Candida die off from it which crashed my adrenals back in the spring. No bueno. I added too much too fast. Anyhow, I might try it again. I've been taking olive leaf, which I like a lot. I recently tried rotating from it to oil of oregano and my stomach hurt badly and I was all gassy. Not sure if I didn't take enough oil of oregano to equal the effect of the olive leaf, if I was sensitive to the oil of oregano or if I was having die off from it (although it didn't feel like die off to me). Anyhow, I switched back to the olive leaf the next day. But I know it's important to rotate antifungals.
