Infant with persistant nasal discharge/bronchial congestion

A friend has an 8 month old infant,male, with what appeared to be the symptoms of a cold soon after birth. Thick yellow nasal discharge, sneezing, phlegm,etc.

This remained a chronic condition until now when there is bronchial congestion/wheezing and much loose thick yellow nasal discharge. There is also an accumulation of thick mucousy phlegm at the back of the throat. Antibiotics are being used but still the symtoms persist. All doctors can recommend is to keep on giving the antibiotics.

A homeopath recommended a product(dissolving tablets) containing Rumex Crispus 3X, Sanguinaria Canadensis 3X, and Kali Bichromicum 3x which lessen the symptoms for a short while(several hours) but do not correct the condition.

The infant has no appetite and it was found that the nasal discharge,mucous,etc, seem to be draining into the stomach because the infant vomited about 1/8 cup of yellow slime.This was not being eliminated by the natural processes but had been accumulating over a period of time.

Any direction on how to correct this would be much appreciated. Thank you.
