Wild cilantro, also known as coriander and Thai parsley, may be the water purifier of the future for low income countries where cilantro grows wild in abundance according to research presented by Dr. Douglas Schauer from Ivy Tech Community College at the Sept. 12, 2013, session of the annual National Meeting and Exposition of the American Chemical Society in Indianapolis, Indiana..
Present technology that can remove lead and other heavy metals from drinking water is too expensive for developing countries.
Schauer’s work with scientists and students from the Universidad Politécnica de Francisco I. Madero in Hidalgo, Mexico found that cilantro was as effective in removing lead and other heavy metals from drinking water as activated carbon. The advantage for that area is that cilantro grows wild and in huge abundance so a cost free source of water purification is available.
Schauer has also discovered several other areas of the world where wild cilantro grows in sufficient quantity to be harvested and used to remove heavy metals from drinking water. These locations include India, Asia, and South America where economies prevent the use of higher technological water purification.
The basic idea is to find a naturally occurring and inexpensive plant or animal product that accomplished the same function as more expensive technology and equipment. The naturally occurring product must be self- replenishing.
