Hmmm... Will wait to see with this. Vermex seems to be the only herbal wormer to be really successful at the moment. I use it and it bought down a high worm count on my mare to a now constant low count.
I use it and have been for several years now. Yes and prefer to Verm X - there is a difference and I understand NoVerms is completely herbal - you can feed to mares in foal and feeding etc whereas you cannot with Verm X.
I like this wormer as not only does it work, it's good value and it doesn't kill the many dung beetles in my paddocks and I need them come manure spreading time!!
