No one talks about Childhood Diarrhea in the United States. It is the most common of death in children worldwide. It accounts for nearly 5 million deaths per year in developing countries. We do not hear about it in the United States. It is one of the fund raisers that need help to abolish. There are many causes worldwide.
Most of the time, the pediatrician recommends a pharmacy product called Pedialyte. This of course is not always available in poorer countries. Every parents wants to help his/her child There are other remedies, both herbal and vitamins that can be used.
Un 1994 the Journal pf Pediatrics published a trial on the use of Homeopathy in childhood diarrhea. I think it is worth repeating some of those homeopathic remedies that were studied and used in the clinical trial. Some of these remedies are
Arsenicum album
German Chamomille
Elemental Sulphur
Mayapple
Not every pediatrician will know about Clinical Homeopathy. You need to do your research
