This is brilliant 'stuff', but please make sure that you go very very slowly with it. This is speaking from personal experience. Start with one drop per day only & really monitor the effects. If you seem to get a strong reaction, try it only every other day, or drink only half the glass of water. Or even stop for a few days. Only increase the dosage when your reaction to the current amount is stable. If you feel really dreadful - STOP! It is not worth just persevering with it, but do try Samento instead. And perhaps retry the Banderol after you've reached the higher dose of Samento. I found Samento milder, but I also started that much more slowly & under the supervision of a medical doctor.
Latest studies found excellent results when alternating Samento and Banderol week by week, finding that the two combined killed all forms of borrelia: spirochete, L-form and cystic colonies.
