My almost three year-old was just diagnosed with Lyme (via the new culture test, so we're sure he has it), and we decided to treat him with herbals first.
Our LLMD recommended a modified Cowden protocol consisting of banderol, samento, and enula, working up to 3 drops/day of each. According to Nutramedix, he would take 1/4 of an adult dose (which is about 7 drops/day).
I'm not sure which dosage to go by. Have any of your children used this protocol? If so, what dosage did you use?
