I read a highly popular book by one of the Lyme disease "Gurus" that was very critical of this product. That author of the book needs to walk a milk in the shoes of a chronic infection sufferer.
Banderol is designed to be a low concentration/low toxicity and "long term use" anti-microbial and I see it as effective in delivering that. "Cowden Protocol" is the empirical theory supporting this product.
I am in the UK and since Brexit it is no longer possible to buy NutraMedix from a UK retailer. I have Lyme Disease and use their Samento and Banderol so that was a problem. Thank good ness for iHerb. Delivery within a week from the US and same price as buying in the UK previously.
