I was reading a thread from 8 days ago where some people were wondering about chelating with coriander. Here is what I know, this protocal is from Dr Klinghardt.
Take 3 tablets of chlorella 40 before lunch then take 30 tablets 20 minutes before lunch. So basically 70 minutes before you have lunch you take 3 tablets, wait 40 minutes then take 30 tablets, wait 30 minutes then you have lunch. Then at bedtime you take 5 to 15 drops of cilantro tincture in a little water. You are not supposed to take coriander without taking the chlorella because the chlorella takes it out of the body.
Chlorella can be a little much on the bowels at the beginning so it's a good idea, the week before you start the chelation to work up to 30, starting with 2 in the morning, 2 in the evening, then next day take 3 etc.
Hope this helps.
