Ellagic acid, also known as TBBD, Gallogen, and Lagistase, can alter cytochrome P450 activity, and improve metabolism and clearance of xenobiotics, as well as alter immune function. It can also block methylation of arginine 17 of histone 3 (H3R17) by coactivator-associated arginine methyltransferase 1 (CARM1), or PRMT4, without significantly altering histone acetylase or DNA methyltransferase activity.
