I'd say, do a bit of research and look around even on ebay for a zapper. They have the weirdest things--maybe a zapper, who knows? Try a search on Dr. Clark's name maybe.
I use the Scada research's RSG-4 zapper--it's around 140 bucks but is very durable and has the zapper body stuff inside one of the hand holds, so you can avoid (as I always do) pulling it on the floor if you forget.
It has a couple different settings too including a sweep function you can probably use for other type pathogens, like virus, etc.(I always used herbs for that, though, so can't say if it really will, but it should)
And don't feel too overwhelmed by all the info in her book though. There's way much information and far more than I ever needed.
Just do the parasite stuff, and focus on what issues and areas of your body they're in. Helps I find to locate the zapper's electrical flow as much thru the infested area as possible, although theoretically anywhere is supposed to be fine.
And a good Liver Flush (she has one in the book) after, is a good idea. Like she says if your liver is full of stones (and nowadays most are) it's like trying to run water thru a hose full of marbles--it impairs function, but doing one won't heal anything. It just enhances your immune function.
Like I said, it doesn't matter which type of parasite--except for curiosity's sake, I guess. Hence I never learned what any of them looked like. They all died just fine. I never even had any visible to 'examine' to begin with. I just had symptoms, so I can't be helpful with that, sorry!.
