Galangin is a flavonol, a type of flavonoid. It is found in high concentrations in Alpinia officinarum (lesser galangal)[1] and Helichrysum aureonitens.[2] It is also found in the galangal rhizome (Alpinia galanga)[3] and in propolis.[4] Galangin has been shown to have in vitro antibacterial[5][6] and antiviral activity.[7] The flavonol also inhibits the growth of breast tumor cells in vitro.[8][9]
