Tumerone is a bioactive compound found in turmeric (Curcuma longa). Its use in supporting or treating Parkinson's Disease (PD) is justified by emerging scientific research, largely in preclinical settings. Animal and cell culture studies suggest that tumerone may exert neuroprotective effects. For example, a 2014 study published in Stem Cell Research & Therapy showed that aromatic tumerone promoted the proliferation and differentiation of neural stem cells in rodents, raising interest for neurodegenerative diseases like PD. Other studies have indicated that tumerone might reduce neuroinflammation and oxidative stress—two processes implicated in PD pathology.

However, this evidence is preliminary. There are no well-designed human clinical trials evaluating the efficacy or safety of tumerone in PD patients. Most findings are limited to in vitro (cell) or animal models, which may not directly translate to human benefit. Accordingly, while tumerone is sometimes included in supplements targeting brain health, its use for Parkinson’s is not established in mainstream clinical practice. The current scientific evidence supporting its use for PD is weak (rating: 2/5), and further research, especially human trials, is needed to determine its relevance in this context.
