Hi Sajafra!
Welcome to our community!! I'm so sorry to hear that both you and your son are dealing with these terrible infections! And no need to apologize for your English!! Even though I live in the US, you should see how I butcher the language sometimes!! Giggle!
If you haven't yet, please do read through our "New to Lyme? Start here!" thread that sits at the top of the forum, as it's packed full of really important information, helpful tips, detoxing instructions, symptom lists (as Lyme rarely passed by itself), and more.
I think this study will help, it was done by Eva Sapi and is titled:
"In Vitro Effectiveness of Samento and Banderol Herbal Extracts on the Different Morphological Forms of Borrelia Burgdorferi"
Here is a link so you can read it yourself:
www.townsendletter.com/July2010/sapi0710.html Essentially, it states that Samento and Banderol are just as effective in treating Lyme disease as high dose Doxycycline - often thought of as the first line defense for Lyme disease.
Please do let us know if we can be of help to you or your son!! We are here to help direct you to information, support you while you go through this, and even to vent to when things seem to be going haywire!
Hang in there and know that you are not alone!
