Coptis Japonica Root Extract

Also-called-like-this: Japanese Goldthread Root Extract
What-it-does: soothing, antioxidant


The extract coming from the root of the traditional medicinal herb, Japanese Goldthread. The plant is used traditionally in East Asia for its anti-inflammatory, antioxidant and antimicrobial abilities.

Other than that, there is also an abstract from the International Journal of Cosmetic Science that found Coptis Japonica Root Extract and its active component called berberine to show potent inhibition of triglyceride (aka fat) accumulation and subcutaneous preadipocytes (the cells that become later fat cells) differentiation meaning that Goldthread Extract might also be useful in slimming and anti-cellulite products.

Show me some proof
