For Parkinson's disease, there is a mushroom that is very good for circulation: Hericium. This can be taken in capsule or syrup form.

What the science says: nerves and the nervous system
Here is what published research says about the remedies mentioned above, for context — these studies address material causes, while healing belongs to Allah.
Nerves and the nervous system
Adapted 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 epilepsies (Dev Med Child Neurol, 2020). Omega-3s, B vitamins, magnesium, and sleep support the nervous system. Precaution: these conditions are followed in neurology; natural remedies accompany treatment, never replace it.
