I am allergic to Malt. All malt's whether it be Malted milk balls or the malt we use to make beer. Luckily for me it's not a bad allergy and I'll just live with the results. I get congested in the nose and sinus area with lighter beers, and depending on the amount consumed and the amount of Malt in higher gravity beers I can get a complete sinus infection in a mater of hours. Luckily I can rinse and within 3-5 days the infection is gone.
With that said, could your friend have a much more serious Malt Allergy? and second... would making a home brew following the gluten free way help me in any way? Does Sorgum have any "Malt" properties? Exactly what is sorgum?
