I don't have a story of it killing worms or anything, but I've been taking it for 4 years and haven't got a cold or flu or anything since. Beggining 18 years ago I would get bronchitis every winter. In 2001 I got it and couldn't get rid of it. The doctor kept kiving me anti-biotics for 3 months. I finally asked her why it wasn't working and she said because it was viral bronchitis. I asked her why she didn't give me an anti-viral then and she said there weren't any. I did a search on the internet found gse at nutriteam and took it and it cured it in 2 weeks. I haven't had any virus type illness since. I take 15 drops in a big glass of oj 2 times a day. When every one is sick around me I put it in "00" capsules and drink a really big glass of water to chase the acid away. My son dilutes it with a little water and puts it on his face for 15 minutes a day before his shower and it cured his acne.
I am stocking up on it just in case of biological warfare.
