activated charcoal

Can activated charcoal cause any herxing or otherwise difficult reactions?

My dr. asked me to begin it today... I'm just so weakened at the moment that I don't want to do anything that could make me feel worse, even temporarily.

It shouldn't cause herxing. It absorbs the toxins through the GI tract and then you get rid of them through BMs.
I used to use activated charcoal, my new LLMD switched me to Chlorella.
Both need to be taken a couple of hours away from abx. I take it right before bed.
