Well how about something that goes through your intestines then?
That will come directly into contact with your parasites!
Like the Russian capsule you swallow and it cruises through your body for about 48 hours? More information on my experience on this or the previous page under 'Sputnik the Russian silver bullet etc..' It does get rid of parasites and some deep seated stuff. In case your worried about sending off to Russia, the seller is based on the Bahamas, if I remember right. Think they are called Alpha-Omega labs. I ordered a variety of items from them and had good service. I do know that since their Website was closed down for a time (big brother in action!)they have since re-opened. I have nothing whatsoever to do with these people. Their prices were always competitive.
If you do use the silver capsule then first make sure you don't re-infect again. First eliminate all the pathogens in your fruit and veg which is where Ascaris normally lives. Always detoxify all your fruit and veg before using.
