i do not recommend anything before removal. i know that some Huggins' clinics do, but we think it can make you sick. yes, the activated charcoal is good to take about 20 minutes before your appt. it helps get stray mercury out of the body. take 2 or 3 capsules. b careful it can cause diarrhea. u don't need to continue taking it, but it won't hurt to take a couple a day until u run out.
i do not recommend juicing cilantro. it is difficult and after a while, u will hate cilantro. i recommend the cilantro tincture or extract. myself, i did not take it, but i ate a lot of cilantro during the time i chelated. Dragon River is supposed to b the best cilantro for detox according to dr mercola of mercola.com click here
