Barb Wilkie's EHN Website
Last updated 2008

EHN Board President Barb Wilkie was very ill from chemically-induced kidney disease for several years. She passed away May 31, 2011. EHN presents this site both as a tribute and as valuable information. Many links and references will be out of date but Barb's research holds up over time. We will be transferring the site page by page, with updated details, to EHN's main site. If you would like to reach an EHN staff person, please contact us directly.
