DO NOT take cilantro without Chlorella and other chelators. Cilantro will only mobilize the metal. It will not remove lead from the body but chlorella will. Chlorella will only absorb the metal from the gut but it will not enter the blood stream. Therefore cilantro and chlorella alone are not enough. They should be combined with other natural chelators like modified frut pectin, alpha lipoic acid, NAC and clay baths. Natural chelation works great for someone who does not have toxic levels of lead in their body. DO NOT take cilantro at all if you have toxic levels. Cilantro allows metal to cross the blood brain barrier and has known to cause neurologigal problems and paralization in those with serious lead poisoning.
