Bell’s Palsy refers to facial paralysis (loss of muscle function) affecting one side of the face and the onset is sudden. The cause in most such cases is not found. The cause is presumed to be inflammation of the facial nerve or reactivation of a previously acquired viral infection. The viral infection behind the cause is herpes simplex viral infection. The triggers which reactivate the latent viral infection include environmental changes like cold air exposure, trauma, and emotional factors. Homeopathic remedies for Bell’s Palsy are made of natural substances and with no side effects, provide a very effective treatment against the disease.
