I'm sorry to hear about it. Actually there are a lot of factors that can trigger eczema. It could be the environment factor or the food you take. Those thing that trigger eczema we call it allergen. When this allergen get into your body, your body cannot accept it, so it will trigger your immune system to fight it as an enemy and finally lead to eczema. Usually for those who have family history of asthma, they are prone to eczema condition. Before i continue with some information to handle eczema, i need to know wheter your girl friend has undergo an allergy test so called Skin prick test. This test will identify types of allergen that the patient should avoid. Usually, if possible, please avoid the allergen in class 2 and above. Patient can get the proper diet advice from a registered dietician.

Basically, beside getting the treatmet from a doctor, I recommend you to seek for some supplement that can help your girlfriend. Basically, those who have low probiotic level inside the body is one of the main reason that trigger eczema. Once your probiotic level is low, your body immune system is weaken and this easily lead to eczema problem. As a dietician, i recommend you to seek for live probiotic or nutritional yeast that could help your girlfriend. There are a lot of brand in the market but please look for those who really work. As a professional, i know that i should give some research to support what I said.

Below are the link of the research that show probiotic really help in eczema:
