I cant offer advice on the nav x but i can say...i have used hilton herbs equimmune for my lads sarcoids and it was fantastic,it shrivelled it right up,and one actually dropped off
I just didnt continue with it as it was very expensive and i went down the liverpool treatment route instead
Anything is worth a shot,all i will say though,is that because they are herbs,you wont see any difference for at least 3/4wks
Thanks hadfos, I suppose I haven't really got anything to lose by trying. I just want to do as much as I can for him as he is such a special horse and so young still.
