Hello - is there a special kind of glycerine that should be used for drinking, or should I just use the same kind that is applied topically? It is for my 7 year old daughter who has inverse psoriasis...we have been applying topically with some success, but I am wondering if ingesting it might be more effective for her. Brian - are you out there? If so, can you share any insights? Dosage? etc? Thank you so much.
