Bell Palsy

Bell palsy is a form of acute, usually one-sided facial weakness caused by dysfunction of the facial nerve (cranial nerve VII). Symptoms often develop over hours to a couple of days and can include drooping of the mouth, difficulty closing one eye, altered tearing, sound sensitivity, changes in taste, and facial discomfort. In western medicine, Bell palsy is often understood as a rapid inflammatory neuropathy, sometimes associated with viral reactivation such as herpes simplex, that causes swelling of the nerve as it travels through a narrow bony canal.

Treatment options vary because Bell palsy has a time-sensitive early phase and a more variable recovery phase. Research suggests that some interventions are most useful when started within the first 72 hours, while other approaches focus on eye protection, preserving muscle function, reducing pain, or supporting rehabilitation in people with incomplete recovery. Integrative care discussions often include both western treatments such as corticosteroids and facial neuromuscular retraining, and eastern approaches such as acupuncture or traditional herbal medicine, where evidence ranges from promising to limited and should be interpreted carefully.
