At a higher temperature, olive oil smokes, not boils, and you don't want it to smoke, because that makes it toxic. I'd say don't heat it over 200degrees F, and only do it for a short period of time. You can see the this on the first page(s) of this thread.

Likely the leaf or powder, and made her own infusion, which is technically also an extract.
