allergy, swollen nasal cavity, extremely dry skin

A friend had asked me (she knows utilize homeopathic/natural forms of everything. She is complaining of very dry skin (that extends to limbs but also nose, throat). She has no thirst (drinks bc she knows she has to). is the same year round (she takes 3 diff allergy meds and I told her this could very strongly be a reaction to that). Prefers heat, can't breath(nostrils swollen so air cannot pass) Started after College (she is close to 40).Mornings are better (before waking)

I've suggested she see a classical for some constitutional work, she may not want to go that far.

I tried to do the rubric on here and the top choices (at 60%) are sulph, puls, lyc, and kali c. When I read the profiles I was leaning towards Lyc and Kali C. But then I consulted a Homeopathic Encyclopedia I came across Mag Sulph.

Anyone have any anecdotal advice on something similar? Thanks!
