Mucuna pruriens

What is it?

Mucuna pruriens, also called cowhage or velvet bean, is a tropical legume that has been used in Ayurvedic medicine for centuries. Its seeds naturally contain L-dopa, which is exactly the active ingredient of the classic Parkinson's medications. So Mucuna is not a harmless supplement, but a natural form of L-dopa.

What does the research say?

In a small controlled study published in the journal Neurology in 2017, a high single dose of Mucuna powder worked about as well as L-dopa and caused fewer excess movements. In levodopa tablets, an added ingredient makes sure that more L-dopa reaches the brain. Without it, you need more Mucuna. Because the L-dopa content varies a lot from product to product, dosing is difficult. That is why Mucuna belongs under medical supervision.

The Spanish neurologist Dr. Rafael González Maldonado, former head of neurology at the University Hospital of Granada, has worked for many years on treatment with Mucuna. He wrote the book "Mucuna versus Parkinson. Treatment with natural levodopa" about it and offers consultations in English and online as well (rafael-gonzalez-maldonado.com). I consider his work very thorough.

My experience

In early 2022, I tested Mucuna for a few weeks with breaks, in small amounts in the evening. It made me feel rather foggy and I had less strength, so I stopped again. At the end of 2023, I took it again briefly as part of my Ayurveda retreat. I have not taken it since.

My conclusion

For me, Mucuna is not a remedy for now, but for later. If I ever start L-dopa one day, I would consider Mucuna as an addition, but only together with my neurologist.
