Well, o.k. Just make sure you keep it at the lowest setting. I have had the most difficult time with fasciola flukes. I am amazed that anyone can live that long with trematodes inside of them. I think I only lasted 10 months before everything turned horrid. I was told also that you could take a 9 volt battery and rub it on the area as well. I don't know how well it would work. Most importantly just be safe. I don't know alot about electricity so, my advice shouldn't be trusted.
