Autism and ongoing treatment, what can we do?

Dear doctors, here is the exact name of the remedies: neurotrophin 4 – 4ch – 20 drops per day, neurotrophic factor 4CH – 20 drops per day. This therapy was prescribed by the homeopathic doctor to my 3-year-old niece’s son, after the chelation therapy which gave excellent results; absent hyperactivity, the beginning of attention and language unblocked with the beginning of requests, in short, eighty percent cured, from autism caused by trivalent vaccine! Having set aside the chelation therapy, to start the one described above, after a few days he starts to have hyperactivity and restlessness, when he communicates it to the doctor he tells me that maybe the dose is too much and he brings it to 10 drops! I wonder if this is really the case or is it the hering effect? The doctor didn’t tell me about the hering effect, but since he didn’t seem so convinced, I would like your opinion! Thank you very much, in advance, Maurizio – Palermo
