My son is 5 years now n I started with his treatment around 3 years age. Initially I had to visit frequently n continue d course fr around 6 months but in these 6-8 months I saw a lot of improvement in his cold n cough. Gradually my visits reduced as with the homeopathic Medicines he was cured very well n d frequency reduced to a great extend. Now at d age of 5 years I hardly have to visit I e once in 6 months as d medicines n homeopathic course has shown wonders. Overall I found homeopathic very good n quick recovery.
