I found Hulda Clark's eBooks for *free* from this website (3 of them)  :

The  book The cure for all diseases, free from the above web site, tells 
how Hulda  used Black Walnut tincture to reduce parasites. I made several 
bottles of  green BW Tincture and use a dropper of it each day just for the 
organic  Iodine. Before I would do a liver cleanse I use 2 teaspoonfuls of the  
tincture. The liver cleanse does not work for me unless I take the BW first. 
 When I made the tincture I made sure to use green walnuts. Hulda called it 
 organic Iodine. I am sorry that I cut down my walnut tree but it was 
taking over  my garage. I planted some more BW trees out where they won't be a 
problem.  Brickey

made several pints of black walnut hull  tincture last year  when there was 
a great windfall of them and then  forgot what it's good for. I think it's 
a sort of iodine, but would it also  work for parasites, like a few drops in 
water a couple times a  day?
