What kind of treatment is there for this?

My friend developed a horrible fear of throwing up in public (he doesn't have a fear of puking at home though or in a car, just when he's out in public in front of ppl).. so whenever he goes out to stores or other places, he gets bad panic attacks (nausea, dry mouth, heart races, sweaty palms, excessive swallowing, etc) but when he leaves he feels fine. It all started with a bout of stomach virus 2 months ago.

What kind of treatment would be available?

Psycho-therputicals, which will lower his adrenaline count.
But if you ask me, he just needs a therapist, or, he should try hypno therapy or something odd like that before he goes to medicine.
