Green tea has long been recognized to have cardiovascular and cancer preventative characteristics due to its antioxidant properties. Its use in the treatment of arthritic disease as an anti-inflammatory agent has been recognized more recently.
The constituents of green tea are polyphenolic compounds called catechins, and epigallocatechin-3 galate is the most abundant catechin in green tea.
Epigallocatechin-3 galate inhibits IL-1–induced proteoglycan release and type 2 collagen degradation in cartilage explants. In human in vitro models, it also suppresses IL-1b and attenuates activation of the transcription factor NF-kB. Green tea also inhibits the aggrecanases which degrade cartilage.
Green tea research now demonstrates both anti-inflammatory and chondroprotective (agents that retard degradation of articular cartilage) effects. Additionally, green tea research includes the “Asian paradox”, which theorizes that increased green tea consumption in Asia may lead to significant cardiovascular, neuroprotective and cancer prevention properties. The usual recommendation is 3–4 cups of tea a day. Green tea extract has a typical dosage of 300–400 mg of the above bio-active ingredients.
