Oral administration of geranium EO protected against Parkinson’s disease in a preclinical model. The researchers concluded that geranium doesn't just mask the symptoms of neurodegeneration—it actually targets the underlying damage. Geranium significantly reduced motor impairment by restoring critical neurotransmitters and slashing alpha-synuclein levels by over 60%. Reducing alpha-synuclein helps prevent the buildup of toxic protein "clogs" that damage brain cells, effectively slowing down the progression of diseases like Parkinson's and helping the brain maintain its normal control over movement.
The oil works by hitting the "reset" button on several internal systems: 1) Neurochemical Restoration: It restored dopamine levels by a staggering 94%, along with significant boosts to norepinephrine and serotonin. 2) Inflammatory Control: It dramatically lowered pro-inflammatory markers like TNF-alpha and IL-6, effectively cooling the inflammatory cascade. 3) Oxidative Balance: It increased glutathione while decreasing malondialdehyde, protecting brain tissue from oxidative stress. 4) Metabolic Support: It enhanced mitochondrial function by increasing LDH and SDH activities—boosting these enzymes helps your cells' power plants run more efficiently, giving your brain the energy it needs to repair itself and stay healthy. These findings suggest that geranium oil is a powerful, multi-mechanistic natural option for neuroprotection and managing the drivers of Parkinson's.
