Yes histamine, but I need to correct some of what you said. It is common people think diamine oxidase break down histamine because the Amiloride-sensitive amine oxidase (AOC1) used to be called DAO in the genetic research. https://www.uniprot.org/uniprot/P19801 https://www.uniprot.org/uniprot/P19801 D-amino-acid oxidase (DAO) is different. https://www.uniprot.org/uniprot/P14920 https://www.uniprot.org/uniprot/P14920 And the other gene is HNMT (Histamine N-methyltransferase). I have never had histamine issues, but just to not that most ant-psychotics work on the H1 receptor and they never worked for me.
