Researchers in India have developed a filter system based on a medicinal herb, which they say can quickly and easily remove "fluoride" from drinking water. The technology described in the March issue of the International Journal of Environmental Engineering uses parts of the plant Tridax procumbens as a biocarbon filter for the ion.
