Although diarrhea can expel germs and toxins from the body, persistent diarrhea can cause dehydration. If your child experiences persistent diarrhea, take him or her to a health care practitioner. If he or she experiences acute diarrhea that’s watery and burns the rectum, consider arsenicum, especially if the child is also chilly, weak and restless.

Podophyllum helps remedy profuse, watery, explosive diarrhea that’s often accompanied by a colicky pain. The stool may be green and have an offensive odor.

Chamomilla is indicated for fever, pain and diarrhea caused by teething. The stool is watery, green and fetid, and the child complains of colic pain. Chamomilla-type children can be irritable or oversensitive to pain.

Colocynthis might help when cramps cause the child to double over at the waist or ball up in the fetal position. The intestines may feel bruised, and the stool may be watery or jelly-like.
