I will explain in detail each product, including what they are, how they work, and why you should use them. If you are going to buy one of these products, you need to read the label carefully.

People who have had an infection for at least three months should be diagnosed with parasite, and treated accordingly. The disease most commonly found in children is cryptosporidium, but other worms and parasites can be found in adults and even infants.
The only treatment to combat a serious infection is to have the infection controlled by medicine. The only way to do that is to treat the infection with a medication which is approved by the FDA. The treatment will usually be prescribed to you by a doctor who has been trained in treating these infections. The FDA has guidelines to help you determine which medications are approved for the treatment of parasites. If you are taking medications that are not listed, it is better to ask your doctor to check with the manufacturer to make sure that it is okay for you to take it.
