Parkinson’s disease affects neurons or nerve cells and is chronic and progressive.
The nerve cells produce neurotransmitter chemical dopamine that sends signals between various parts of the brain.
This coordinates muscle movements.
When this gets impaired, body movements are affected.
Common symptoms include tremors, muscle rigidity, changes in posture or walking pattern, loss of balance, changes in handwriting and speech, increased falls and bradykinesia.
Genetic and environmental factors are held responsible for the development of Parkinson’s disease.
In Parkinson’s disease, a protein named alpha synuclein starts accumulating in the brain at abnormal levels and leads to the formation of Lewy bodies.
There is a reduction in dopamine levels, a neurotransmitter which leads to the death of brain cells in the midbrain (substantia nigra) and this impairs motor function.
Treatment involves medication called levodopa which rectifies the reduction of dopamine levels.
Other medicines like dopamine agonists, MAO inhibitors may be prescribed and even surgery is one of the treatment options offered.
There is ongoing research that is trying to identify the precise causes of Parkinson’s and a cure. Until then, with available treatment and proper care, patients can live fulfilling lives.

7 Reasons Why Turmeric Could Help In Parkinson’s
Selective deterioration of dopaminergic neurons causes Parkinson’s, which is an age-related neurodegenerative disease.
Current treatment for this condition aims at replenishing striatal dopamine.
However, these medications do not help in the long-term and even cause motor complications.
They also do not prevent other Parkinson’s symptoms like postural instability, tremors and cognitive defects, nor are they neuroprotective.
New studies are being conducted on the use of antioxidant herbal remedies in treating Parkinson’s. Turmeric compound curcumin, a polyphenol, has anti-inflammatory, anti-cancer and antioxidant properties besides having neuroprotective capabilities since it can cross the blood-brain barrier.
Herein we have assessed 50+ research studies to give a fact-based detailed outlook as to how turmeric shows therapeutic potential in Parkinson’s disease.
1. Turmeric has multiple benefits in Parkinson’s disease
As an antioxidant, curcumin prevents the action of free radical species, peroxynitrite which causes oxidative damage to brain cells in Parkinson’s.
In an animal model of Parkinson’s disease, curcumin is found to bring about various positive changes.
It prevented the reduction of antioxidant enzymes in the brain which otherwise would cause cell death in the brain.
It also prevented the reduction in brain chemicals like dopamine and acetylcholine which are vital in brain function. Curcumin elevated the levels of proteins that are essential for maintenance and nerve growth.
Homocysteine is an amino acid which is elevated in Parkinson’s disease and this contributes to neurotoxicity. Curcumin protects the nervous system from homocysteine-induced toxicity and prevents impairment of motor function.
As antioxidant curcumin inhibits the destruction of neurons in the substantia nigra and prevents the reduction in dopamine levels.
Curcumin counteracts the inflammation caused by neuronal degeneration induced by reduced dopamine levels.
Curcumin is identified as one of the phytochemicals present in a plant-based diet which could be of the relevance of treating and preventing Parkinson’s disease.
A report published in the Journal of Ethnopharmacology, 2016 suggests that even Ayurveda- traditional Indian medicine system recommends turmeric for Parkinson’s.
What does this mean?
Curcumin benefits in Parkinson’s disease in multiple ways: prevents reduction in dopamine, reduces oxidative stress, prevents cell death of dopaminergic neurons, prevents inflammation, memory deficits and motor impairment etc. Dietary curcumin can prevent Parkinson’s disease.
2. It protects brain cells from cell death
Cell death of neurons or brain cells that produce neurotransmitter, dopamine is characteristic of Parkinson’s disease and impairs motor function.
An animal study was conducted to examine whether turmeric consumption could help in protecting the dopaminergic neurons from cell death in Parkinson’s.
Parkinson’s was induced by administering a drug named MPTP which produces symptoms similar to the disease.
The death of neurons in Parkinson’s occurs as a result of mitochondrial dysfunction; mitochondria are powerhouses of the cell and aid in cellular respiration.
Turmeric supplementation protected from neuronal cell death occurring as a result of this dysfunction.
It also prevented abnormal changes in neuronal proteins which are a marker of oxidative stress. Curcumin derivatives also show similar action.
Another study also proves that curcumin protects the brain mitochondria which is of relevance to Parkinson’s disease treatment.
CNB-001, a novel derivative of curcumin is found to protect the dopaminergic neurons from cell death in Parkinson’s disease.
Curcumin is famous as a chelating agent- it accumulates toxic metals as compounds that can be excreted.
By virtue of its iron-chelating properties, curcumin is found to suppress iron-induced degeneration of dopaminergic neurons- the loss of which leads to symptoms of Parkinson’s disease.
What does this mean?
Curcumin’s anti-inflammatory, anti-apoptotic, antioxidant and chelating properties protect dopaminergic cells from cell death.
3. It prevents the formation of Lewy bodies
Alpha-synuclein is a protein found in brain cells. In Parkinson’s disease, these proteins undergo changes in structure which cause cell death in brain cells.
It forms protein aggregates called Lewy bodies.
Curcumin is found to inhibit such activity by inhibiting oxidative stress-imbalance between prooxidants and antioxidants. Curcumin inhibits overproduction of alpha-synuclein and prevents its mutations.
Macroautophagy is a process that degrades that proteins in cells and this process is impaired in Parkinson’s disease due to an accumulation of protein-alpha synuclein.
Curcumin reduces the accumulation of alpha-synuclein by recovering the macroautophagy process.
Researchers at Oregon Health and Science Institute have found that curcumin treatment prevents motor function impairment occurring as a result of alpha-synuclein accumulation.
Curcumin activates the level of transcription factor EB, a protein that regulates autophagy and in turn reduces neurotoxicity.
Autophagy degrades the accumulation of protein alpha-synuclein.
Curcumin has the ability to cross the blood-brain barrier and inhibit alpha-synuclein accumulation and toxicity in Parkinson’s.
What does this mean?
Alpha synuclein protein accumulates in the brain leading to formation of Lewy bodies in Parkinson’s disease.
Curcumin inhibits accumulation of alpha synuclein and this is extremely important especially if science develops a way of delivering curcumin to the brain.
4. It inhibits enzyme monoamine oxidase to protect brain cells
Glial cells surround the neurons and provide them with protection.
In Parkinson’s disease, they produce abnormal amounts of an enzyme monoamine oxidase which causes oxidative damage and leads to cell death. Inhibition of this enzyme can aid in the treatment of Parkinson’s.
In an animal study curcumin and its derivative tetrahydrocurcumin was found to reverse dopamine depletion and inhibited the activity of monoamine oxidase in Parkinson’s disease.
What does this mean?
Curcumin inhibits the activity of enzyme monoamine oxidase similar to that of medications-MAO inhibitors that are prescribed to manage Parkinson’s.
5. It protects cognition and remedies of depression
Animal study shows that curcumin prevents age-related cognitive and memory deficits.
Curry consumption is associated with better cognitive performance in elderly Asians due to the presence of curcumin.
Curcumin supplementation in the healthy older population is found to increase attention, working memory and mood.
Curcumin supplementation is as efficacious as Prozac or fluoxetine in treating depression. Review of clinical trials investigating the role of curcumin in depression also points out that curcumin is an effective add-on therapy for depression.
What does this mean?
Curcumin supplementation can improve cognition and reduce memory deficits and depression in Parkinson’s disease.
6. Curcumin may improve motor function in Parkinson’s
One of the major symptoms of Parkinson’s diseases is difficulty in movement. The accumulation of α-synuclein leads to stiffness and rigidity in movement.
It is proven that dietary administration of curcumin can bring about significant improvement in gait impairment in an animal model of Parkinson’s.
CNB-001, a novel derivative of curcumin, It protects the neurons by anti-inflammatory and anti-apoptotic properties and mitigates motor impairment.
A recent study published in Pharmacology, Behaviour, and Biochemistry, 2016 demonstrated that curcumin attenuated movement related deficits in an animal model of Parkinson’s by increasing the level of antioxidant enzymes.
In a fly model of Parkinson’s disease, curcumin reduces oxidative stress, delays loss of motor function and increases lifespan.
Researchers have studied the effects of curcumin in various developmental stages in the fly model in Parkinson’s disease. Curcumin is found to protect from motor defects in early stages of life.
What does this mean?
Dietray curcumin may prevent motor function impairment and may improve motor function in Parkinson’s.
7. Curcumin derivatives have potent therapeutic action in Parkinson’s
Various derivatives of curcumin have been developed which show enhanced neuroprotective activity than curcumin in case of Parkinson’s.
- Protecting dopaminergic neurons in the brain
- Reducing oxidative stress and protecting mitochondrial function
- Attenuating impairments in movement
- Suppressing neuroinflammation
Liposomal curcumin (curcumin wrapped in fat like structures) is proven to improve motor function, prevent apoptosis in neurons and stimulate dopaminergic neurons as a means to ameliorate symptoms linked to Parkinson’s disease.
Curcumin glucoside, a derivative of curcumin, prevents clumping and aggregation of α-synuclein.
Curcumin and its metabolite, tetrahydrocurcumin also offers neuroprotection and reverses brain damage.
What does this mean?
Various compounds are being developed from curcumin which are more potent than curcumin itself in treating symptoms of Parkinson’s and have the potential of being developed into clinical drugs.

The dosage of Turmeric for Parkinson’s
The most common way to take turmeric is in spice/powder format. More details on dosage here
Including turmeric in the diet is very very easy. You can add it to anything you cook. You can check some great recipes in recipe section of the website too.
Always include black pepper in the diet so that you can get the full benefit of turmeric. This is because turmeric’s absorption in the body is low. Black pepper enhances it. More details on black pepper + turmeric benefits here
Curcumin, the active ingredient of turmeric is poorly absorbed in the body. Natural ingredients like black pepper and oil increase its absorption. Therefore we recommend taking Golden Paste, a recipe that combines all three.
You can start with ¼ to ½ teaspoon a day and gradually increase the dose to 1-2 tsp 2-3 times a day or how it suits you.
In the early stages of Parkinson’s or for dementia, dietary turmeric can be of help. However, research is focused on optimizing curcumin as a treatment for Parkinson’s disease.
Turmeric spice does not cause any side effects when used in food. Turmeric in the diet is safe and studies show that supplementation doses up to 8g do not cause side effects.
But it is not advised to take such high doses. Also if you are new to turmeric you might experience slight gastric issues which fade away gradually.
Turmeric supplements should be taken when advised by a doctor. Curcumin has blood thinning property and hence turmeric supplements are to be avoided 2 weeks prior to surgery. Also, avoid supplements when taking blood thinners.
Turmeric supplements should be avoided in pregnancy and lactation. They are not recommended if suffering from gallstone obstruction. Turmeric supplements may interact with blood thinners, blood sugar lowering medications, stomach acid reducing drugs and certain antidepressants.
Turmeric is high in oxalates, so if you are suffering from kidney stones or gout it is advisable to limit intake of turmeric as a spice and consult a health practitioner for turmeric supplements if needed for therapeutic action.
Parkinson’s disease does not have a cure to date.
However, the inclusion of foods that are good for brain health can help prevent Parkinson’s disease.
Dietary turmeric can help prevent Parkinson’s and research on experimental models show that curcumin can aid in the treatment of Parkinson’s disease in multiple ways: reducing oxidative stress, reducing accumulation of proteins in the brain and regulating abnormal levels of neurotransmitters.
Studies on humans and ways to deliver curcumin to the brain at therapeutic doses for Parkinson’s treatment are required and it is actively researched upon.
