She's missing 2 hp and 4 str yes, then she is exhausted (-6 str and dex, can't run or charge). After 1 hour of complete rest, she will become  fatigued (-2 str and dex, recover after 8h rest). While she is doing mental tasks like spellcasting and fightin in her companion she is not 'resting' though. That said, condition removal might help her, or simply taking her to a safe area where she can sleep it off.
