She may:

Look at your tongue
Look at your eyes (iridology)
Get you to drink a bit of this zinc-liquid to see if you're deficient (if you are, it will taste metallic then like water, as the body absorbs it via the mouth; if not it stays metallic)

Ask you about fun things like bowel movements

Talk about your diet and exercise...

That's all i can think of for now.

But do be aware that they sometimes like to prescribe a LOT of herbs, supplements etc and they can cost a LOT (see my recent acupuncture post!).

Hope that helps!
