My husband and I are both using it...we love it so far. I did find a dead remnant of a tapeworm and maybe some flukes just a few days after starting Clarkia. (found it from enema) The side effects we have found are tiredness, and sometimes itchiness. But if I don't feel any die-off, I am drawn to taking more! So glad to kill whoever is residing inside me, rent-free. I, myself, am using 30 drops 3 x a day, he is taking about 20 drops 3 x per day. I like the tincture since it can be used in an enema, or the strength can be altered depending on if you want more or less. I would recommend it, it is basically Hulda Clark's recipe. The tincture is also easier than figuring out the dosage for each individual pill myself.
