Have not used salt for parasites but have used a very effective all natural cleanse by DrNatura called Colonix. It helped me with my constitpation and parasite problems. I did not realize I had parasites until a month into the cleanse when I started eliminating some odd looking things. I did take them in to be tested and it was confirmed as parasites. This cleansing program really helped me, my family and friends. It really changed my life. I did try other products before colonix and after but nothing comes close to the way it works and feels. Great stuff.
