Hi
There was a thread on this subject some time ago which became a bit controversial if I recall rightly
. BNM is a herbal remedy, which if you are happy to use I'm sure has benefits but if like me, you prefer scientifically proven and certified medications you may wish to do further research before making a decision - which I guess is the purpose of your post!
What do you want to use it for? Is it something specific or general preventative as there may be others on here with their experience or suggestion of alternative products.
The main ingredient in BNM is neem. After a lot of research, which included purchasing BNM and using it for a short time, Pearl now wears a scalibor collar from March - September and is the treated with Stronghold (mites) moving on to Frontline over the winter!
