I think we are of a similar mindset. Both chemical drugs and natural remedies have their place, and should be used appropriately and to the extent of their respective effectiveness.
I am in the UK and have regularly bought VermX to maintain good gut health and deter worms, so I'm interested in...
Perhaps it is better viewed as an 'inhibitor' rather than a true preventative treatment because it helps to create a hostile gut environment where parasites can't thrive.
Doesn't mean they won't have any, but perhaps they won't stick around and breed ifswim, so an infestation becomes far less...
Very interesting and I'd love to have your recipe.
I'm a fan of natural remedies and preventatives, but like you, I'll dose them up on drugs when it's needed!
