Facial paralysis is very often caused by stress, and our Prophet ﷺ told us: "Do not get angry." To fight stress, it is good to take talbina with olive oil, as well as two teaspoons of flaxseed twice a day, accompanied by dates. It will also be beneficial to drink ginger and turmeric herbal teas.
In addition, it is possible to apply a turmeric and ginger cream to the face, or to massage the face with warm olive oil and three drops of clove essential oil, as this warms the area, and the paralysis may have been caused by exposure to cold.
As a dietary supplement, there are two essential things: cod liver oil, one teaspoon morning and evening, and vitamin B12 in tablet form or by injection to speed up healing.
What the science says: nerves and the nervous system
What published research says about the remedies mentioned above, for context — these studies concern material causes; healing belongs to Allah.
Nerves and the nervous system
Appropriate physical exercise improves mobility and reduces falls in Parkinson's disease according to a Cochrane review (Cochrane, 2023) (Neurorehabil Neural Repair, 2020); vitamin D is being studied in multiple sclerosis (J Nutr, 2024) and the ketogenic diet in certain drug-resistant forms of epilepsy (Dev Med Child Neurol, 2020). Omega-3s, B vitamins, magnesium, and sleep support the nervous system. Precaution: these conditions are monitored in neurology; natural remedies accompany treatment, never replace it.
