What are the herbal remedies for cold I can give to a five year old child.?

Honey, saline... Dark honey has been shown to help many children with cold symptoms. Honey should be given to children over 12 mo of age. Also, saline (made at home with non-iodized salt and water) or purchased as a nasal spray is very effective for nasal congestion. Also good-old vapor rub has been shown to be effective to improve cold symptoms and sleep at night in children over age 2.
