I think most of us are worried that the parasites will become use to the herbs and they will become resistant to them, making them not work anymore.
I take a brake between full moons(both moons new and full) with the blackwalnut, Wormwood and clove pills, but I take others things inbetween that still kills worms, bee propolis, L-cyestine, elecampane, pomegrante and now castor oil pills. Not all at the same time, I take one of these in between moons. I change what I take each month. Thanks for your info, I think it will help others out...heyjude
