Enzyme Assisted Extraction of Green Tea for Superior Results
Since inflammation and oxidative stress appear to play a significant role in the aging process, green tea has anti-aging effects by decreasing inflammation and scavenging free radicals. Researchers have found that the main active ingredient in green tea, epigallocatechin-3-gallate (EGCG), works well as an anti-inflammatory, antioxidant, and sunscreen. Topical green tea applied to human skin has been shown to provide a photoprotective effect, reduce the number of sunburn cells, protect epidermal Langerhans cells from UV damage, and reduce the DNA damage that formed after UV radiation. Green tea polyphenols, when combined with traditional sunscreens, may have an additive or synergistic photoprotective effect. Green tea has also been found to decrease melanoma cells in tissue culture and squamous cell carcinoma cell formation in mice with topical and oral administration.
Additionally, it improves wound healing by increasing keratinocyte cell differentiation and has been shown to inhibit Streptococcus species and Escherichia coli. Green Tea is high in polyphenols. Green Tea has many excellent anti-aging properties via polyphenols.
There are many ways to extract green tea, including hot water extraction or through an organic solvent like alcohols.
