dear chemar,
when I lived in VA. Beach in the 1990's - I had a neighbor that was told me to
take it to strengthen my immune system, because I was sick with a bad chest colds (yearly) and laryngitis sp?
I took it and goldenseal for a short amount of time, the tinctures!
good brands and I have been well -except for PD?
ever since! and that has been well over a decade!
gawd? I'm talkin in decades!! hahaha!
PS: you are not suppose to use it more than a 2 week span - but I use it every year!
love ~
