Hmm, I think I got the wrong guy. I called Dr John Cahill's office. He's also in NYC and he works in emergency medicine and infectious disease at st Luke's Roosevelt and he founded who founded the Center for Global Collaboration & Health Initiatives. I just assumed that was the guy to c. My nasal and eye itching pretty much resolved with high doses of salt. I took about 10,000 mg a day for a couple of weeks. Not for everyone but I felt relief start immediately with first day and I didn't notice any side effects. I also did and am still doing about 12,000 mg vitamin c a day. That I continue as part of my mission to eradicate these pinworms..
