Baicalein (5,6,7-trihydroxyflavone) is a

Sho-Saiko-To, which is a Chinese classic herbal formula, and listed in Japan as Kampo medicine.[citation needed

Baicalein, along with its

myorelaxation.[7][8][9] It is thought that baicalein, along with other flavonoids, may underlie the anxiolytic effects of S. baicalensis and S. lateriflora.[10][11] Baicalein is also an antagonist of the estrogen receptor, or an antiestrogen.[11]

The flavonoid has been shown to inhibit certain types of lipoxygenases[12] and act as an anti-inflammatory agent.[13] It has antiproliferative effects on ET-1-induced proliferation of pulmonary artery smooth muscle cell proliferation via inhibition of TRPC1 channel expression.[14] Possible antidepressant effects have also been attributed to baicalein in animal research.[15]

Baicalein is an inhibitor of CYP2C9,[16] an enzyme of the cytochrome P450 system that metabolizes drugs in the body.

A derivative of baicalin is a known prolyl endopeptidase inhibitor.[17]

Baicalein has been shown to inhibit Staphylococcus aureus biofilm formation and the quorum sensing system in vitro.[18]

It has also been shown to be effective in vitro against all forms of Borrelia burgdorferi and Borrelia garinii.[19]

Glycosides
