If you go to the homepage, scroll down the left hand side of the page and click on parasites, you will find out all you need to know about getting rid of those critters you have in your body. It only requires three ingredients---wormwood, Black-Walnut tincture and cloves. Simple as pie.
Or, you can go to your local health food store and buy a box of parasite cleanse---"ParaGone" is one, but there are others.
The important thing to remember is to begin the program and then forget about it.(A typical cleanse is 30 days) The reason I am saying this is most parasites take awhile to die off, so if you are constantly checking your toilet, you will begin to think it's not working. If you see rice-looking particles, those are parasite eggs. The Mama and Daddy are still in you hiding.
Taking a whole bottle of Co-Q-10 (3,000 milligrams) is a parasite killer, too. Look into purchasing a zapper. Dr. Clark explains this, too. It kills parasites, too.....
As far as the ultra sound, I would tell you NOT to do that. Just begin the series (and it takes more than one) of Liver Flushes and seeing the stones floating in your toilet is all the proof you need. Read all you can about the different things you can take to crush your stones and decide for yourself what you want to take.
Then flush away. Any questions you have, someone will be glad to answer it. Good luck and good health to you!
