Black walnut hulls top many anthelmintic lists; I don’t like it; I don’t use it
Echinacea (Echinacea purpurea or Echinacea augustifolia) was tested in several large dairy goat herds in New Zealand. A teaspoonful of ground dried root added to feed on a daily basis gave excellent control of worms. Echinacea is currently selling for around $30 pound wholesale.
Garlic is Juliette de Bairacli Levy’s favorite worm remedy. She ferments garlic in lemon juice for several days while fasting her dogs. Then feeds the fermented garlic (probably with some raw meat) to her hounds to blast the worms right out of them.
Rue, whether fresh or dried, tinctures or brewed in water, contains volatile oils that can kill worms – or injure the kidneys and liver. I don’t use or recommend rue.
Tansy is another plant rich in worm- (and liver- and kidney-) killing compounds.
Wormwood (Artemisia absinthemum) has a great reputation as an anthelmintic. It is very bitter and may cause central nervous system problems with long use.
Mugwort/Cronewort (Artemisia vulgaris) is my favorite and the one I rely on.
CRONEWORT is a weed throughout much of the world. It is related to wormwood, but packs a milder punch. I make sure there is plenty for my goats to browse. I also harvest and dry the flowering stalks to insure a supply through the cold months and during kidding season if it occurs before the cronewort is up. I don’t use a specific dose, merely allow the goat to eat as much, fresh or dried, as she wants. I have not had to use any chemical wormers in my herd for more than thirty years.
