I have been doing alot of research about parasites and the infections they create ... I recently found out that u can use Reeses Pin X ...they sell this over the counter for and roundworms infections not just pin worms.. Fyi. Back in the day our great grandparent used kerosene and turpintine oils for nearly everything you could imagine ... Now sold as turpintine Pure gum spirits . research the web ... Find out how to dose. Or bath soak remedies. ...also. Caniada infections greatly reduced from dosing too ..make sure you search web and do your reading up on the subject ..good luck too all ..I've been going through this for a couple of years now and in about to try myself. Will let all know how it works soon .
