Your daughter is more than likely suffering from a compromised immune system. “Autoimmune Disease” There are many possible causes.
Pesticides, sprays, chemicals, chlorine in water, fluoride in water, overuse of antibiotics, mercury and other adjuvants in vaccines WIKI ~ (Adjuvants are pharmacological or immunological agents that modify the effect of other agents (e.g., drugs, vaccines) while having few if any direct effects when given by themselves. They are often included in vaccines to enhance the recipient’s immune response to a supplied antigen while keeping the injected foreign material at a minimum.) ~ which can result in food sensitivities to gluten, pollens, soy products, margarine, milk products, etc etc etc. Yet knowing all this does not help your daughter. Only by taking the right action will she be helped.

My granddaughter Jorja had a similar problem and it was very disturbing to see a young child with dry skin and always scratching. The first thing her parents did was put a carbon filtration system on their house water supply. After a short while a reasonable improvement was seen. Then we supplied them with a life ionizer to help her hydrate better and improve her body PH, into an alkaline position and detoxify her body. Both systems cost a total of about $2,000.00. Over the last 6 months we shared about three manna sachet with her because before taking the manna, she would have coughs that would last for months at a time. Now she is free of both the skin problems and the coughs.

One basic thing that can greatly help is eating organic foods that are not GMO and have not been sprayed with pesticides and chemical fertilizers.

You may want to try removing margarine and canola oil from her diet and replace it with olive oil and virgin coconut oil, if you haven’t done so already.

What I do know is, God is love and love provides simple things to overcome complex problems. Keep asking and keep seeking your answer will come.
