Stephen Buhner’s Healing Lyme disease protocol references 500mg polygonum cuspidatum tablets (Japanese Knotweed).  Those tablets are “standardized” to 8% Polygonum Cuspidatum content.  Belfast Herbs 500mg capsules are 100% powdered root & rhizome of the plant. Also recomended for bartonella.


Due to the blood thinning characteristics of Polygonum Cuspidatum we feel it is prudent at least initially to reduce the quantity of capsules taken by a factor of approximately one capsule for ten tablets recommended in the Healing Lyme protocol  for Borrelia Burdorferi and or the co-infection Bartonella unless directed otherwise by your healthcare practitioner.
