Almost 120 years ago, Ehrlich (25) established that febrile infectious illnesses caused increased urinary excretion of aromatic amines which were identified several decades later as Trp catabolites
of the kynurenine pathway (26).
Although the identification of polyphenolic catabolites
was until recently confined to very well equipped laboratories, the necessary analytical facilities are now readily available in most research laboratories and are increasingly being used to investigate the metabolism of polyphenols by humans.
The results showed that right hemispheric chemically dominant/ Kapha state had elevated digoxin levels, increased free radical production and reduced scavenging, increased tryptophan catabolites
and reduced tyrosine catabolites
, increased glycoconjugate levels and increased cholesterol: phospholipid ratio of RBC membranes.

in human serum.
However, the underlying mechanisms for the estrogenic effects of PFIs have not been completely clarified, and further studies are also warranted to characterize possible catabolites
of PFIs, which might also exhibit estrogenic activity.
