Cilantro has been known as something used in Mexican and Southeast Asian Cuisine but now it looks like it can do more than that – purify water in a cheaper way which should be good news for developing countries.
Cilantro can reportedly be a bio-absorbent which means that it can help take out harmful lead and other toxic stuff from contaminated water. Douglas Schauer, Ph.D has done research on bioabsorbents and it looks like the Cilantro (Chinese parsely) is the effective and cost-friendly filter that can do the trick.
The plant is easily grown both at home and in the wild, making it readily available for many developing countries afflicted by a contaminated water supply. The key to the plant’s success lies in the architecture of its outer cellular walls that make cilantro ideal for absorbing toxic metals such as lead.
