Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Green tea (Camellia sinensis) is sometimes explored as a supportive intervention for Parkinson’s Disease (PD) due to its rich content of polyphenols, particularly epigallocatechin-3-gallate (EGCG). Laboratory and animal studies have provided some scientific rationale for green tea’s potential in neurodegenerative disorders. Research demonstrates that EGCG possesses antioxidant and anti-inflammatory properties, and it may reduce dopaminergic neuronal loss—one of the hallmarks of PD—by scavenging free radicals and inhibiting pathways involved in cell death. Small-scale animal studies have shown neuroprotective effects of green tea extracts, with some evidence suggesting improved motor function and reduced neuronal damage in toxin-induced models of Parkinson’s. However, evidence in humans remains limited. A few observational studies have reported a lower risk of PD in populations with higher green tea consumption, but these findings are not consistent, and randomized, controlled clinical trials are scarce. No major medical guidelines recommend green tea as a treatment for PD, and its use in this context is not widespread in traditional medicine systems either. In summary, while there is some preclinical scientific basis suggesting green tea’s neuroprotective potential in Parkinson’s Disease, high-quality clinical evidence remains insufficient. Its use should be considered complementary and not a replacement for established therapies, pending further research.
