Is there ANYTHING that can kill systemic parasites. Everything seem to just mainly be for GI. Have them in jaw area. Have tried numerous things and nothing seems to actually KILL it/them all the way... Tried all Hulda Clarks methods. OOlive oil and L Cysteine seemed to help but not totally erradicate. Want to keep doing it but says only do for three weeks... Any suggestions. Also tried the basic three... BWalnut, Wwood clove. Thanks for any input. This is altering my life...........
