Cilantro [also known as Chinese Parsley] has been studied with promising results regarding its chelating [binding with and removing from the body] potential for helping the body eliminate heavy metals such as mercury and lead.
The contention that cilantro is a powerful chelation agent is based on the work of Dr. Yoshiaki Omura, President and Founder of the International College of Acupuncture and Electro-Therapeutics and Director of Medical Research of The Heart Disease Research Foundation.
