Cilantro: Not Only Tasty, But Purifies Water

 

The next time you find yourself facing some questionable drinking water, look for some cilantro.
At least that’s what a team of U.S. and Mexican researchers made up of undergraduate students suggest.
The research team, lead by Douglas Schauer of Ivy Tech Community College in Lafayette, Ind., along with colleagues from the Universidad Politécnica de Francisco I. Madero in Hidalgo, Mexico, have been studying the region of Tule Valley near Mexico City to identify cheaper ways to filter water.
Time.com reports, after testing various samples of plants from cacti to flowers, the researchers determined that cilantro is the most prevalent and powerful so-called bioabsorbant material in the area. Bioabsorption is the scientific term for using organic materials often found in plants, that when dried, could replace the charcoal currently used in filters.
The team suspects that the outer wall structure of the tiny cells that make up the plant are ideal for capturing metals. Other plants, like dandelions and parsley may also provide similar bioabsorbant capabilities.
Schauer says ground cilantro can be inserted into a tube into which water is passed through. The cilantro allows the water to trickle out but absorbs metals, leaving cleaner drinking water. Dried cilantro can also be placed into tea bags that are placed in a pitcher of water for a few minutes to suck out the heavy metals.
So far, the researchers reported success in removing lead and nickel with their cilantro filters, and are studying how well the herb can removed other heavy metals found in the Tule Valley water such as arsenic and mercury.
“We are hoping we can look at how cilantro absorbs those metals, and see if those metals work in some kind of synergy when they come into contact with the biomass,” says Schauer. “We need to look at mixtures of metals to see if cilantro evenly pulls all the metals out.”
