Hello - I would not recommed it especially if it contains black walnut, wormwood, male fern or any other strong parasite killers. Most herbs have several different names
I know it's hard to wait - but the risk of creating super parasites is just too great, in my opinion. Try just using the natural herbs that are anti-parasitic: onions, garlic, ginger, sage, thyme, cloves and cinnamon - they'll help keep them at bay - but are not strong enough on their own to totally kill them.
