Hi,
Know this is an old biofilm post but if anyone new is reading this there is a homeopathic product that busts the biofilm off of the teeth of pets. Am thinking this might work on people also and for more than "teeth biofilm".
It is Fragaria Vesca (wild strawberry). You can get the little pellets on ebay, about $16 - $17 per bottle.
Anyone know if this works on the other biofilm in the body?
