I am also a member of the International Parasitology Society.
Here I list the products that I've found to be helpful against parasites. For each product, I give a short description of the products, including the manufacturer, the company, the product's safety, and the manufacturer's web address. I also list the product's ingredient list, the manufacturer's address, and the web address where the manufacturer can be found. I believe that these products have worked. In the case of some of them, I would recommend that people try one of the products first. This is especially true of products that contain more than one ingredient. Products that don't have safety ratings, or are labeled only for topical application, should only be used with a doctor's advice.
I also don't list the ingredients of products that are more than a few years old. The data I give on these products can be found in the products' labels. Here are some general rules of thumb. If I don't know the name of the company, I'll usually assume the product is safe. If the label says it's not for topical use, I would ask for a copy of the label or information about how it's safe to use.
