Elecampane is an herb.....
There is a web site that is very good, it tells you symptoms, what they look like, and different things you can take for parasites, www.innvista.com if you haven't been there you need to check it out. I have tried many of the things it listed over the past two years.
Elecampane is an herb it is specific for the roundworm Ascaris lumbricoides(the whitish, thick roundworm), having a paralyzing effect on the worm's central nervous system, It is recommeded as the safest herb for children and has been known to be a benefit for lung ailments and digestive disorders.
I have had many ascaris, and this herb has helped to get them out. I also have used it alone before, my neice uses it alone each full moon because she can't afford much and it cost around $6 a bottle, she hasn't gotten out Ascaris but gets out flukes and tanish roundworms each month. Maybe she doesn't have Ascaris in her?!?! heyjude
