It depends on the nature of the paralysis. For cases of Guilain-Barré Syndrome, homeopathic Conium (Water hemlock in homeopathic potency) has been useful. I cured a case of brachial plexus palsy with Hypericum (St. John's wart in potency). Paralysis due to MS is more complicated and a wide variety of medicine have been use, from plant, animal and mineral sources. Rhus-toxicodendron potentized has been useful for certain cases of paralysis.
