Usually, acupuncture treatment helps depression. Some severe depression may need longer care. Knowing your mother's health condition will help to say if acupuncture can help her or not.
Acupuncture along with HERBAL medicine should be helpful on the condition that your mother does not take any other meds that might interfere.
So yes, don't walk, run to an acupuncturist who has treated depression, and start getting your mom some relief!
If your mother's condition gets extreme, I would advise she try medications to keep her balanced while getting other treatments as well.
