Anti-eczema potential of three tea extracts: mechanisms of anti-inflammatory, antibacterial, antioxidant, and immunomodulatory effects.

ABSTRACT:

Background

Tea, with a long history in China, is known for its anti-inflammatory and antioxidant properties. Limited research exists on its use in eczema treatment. This study explores the effects and mechanisms of three tea extracts-Camellia sinensis var. assamica (Royle ex Hook.) (Theaceae) (CS), Camellia ptilophylla Hung T. Chang (Theaceae) (CP), Camellia arborescens Hung T. Chang, F. L. Yu & P. S. Wang (Theaceae) (CA). On eczema induced by 1-chloro-2,4-dinitrobenzene (DNCB) in mice and to explore the underlying anti-inflammatory and immune regulatory mechanisms.

Methods

The metabolites of tea extracts were analyzed using ultra-high performance liquid chromatography/quadrupole Orbitrap mass spectrometry (UHPLC-Q-Orbitrap-MS). A DNCB-induced dermatitis
