Is it permissible for a mother to hit her twenty-year-old daughter for refusing to comply with treatment, "for the sake of her well-being (maslahah)"?

Scholars differ on the ruling concerning a father hitting his adult son. However, it is not permissible for a mother to hit her adult daughter for not responding to treatment, unless abstaining from treatment would lead to her perishing. This is because treatment is not obligatory according to the majority of scholars, unless it is known that abstaining from it will lead to perishing. Many proofs supporting this have been cited.
