That modern herbal medicine link you posted Omo about liver detoxification and histamine levels etc.. is extremely useful.
I feel it deserves a thread of it's own in the relevant forums.
I have always had liver problems - heck i even have 3 deep lines inbetween my forehead - that the average 'lay-man' would consider wrinkles...but i've had them since my teens! Facial diagnosis is something i think will become more popular in time.
When i was 2 days old i had jaundice. My mother didn't look after her health. I've always had sensitivities to chemicals, medicines, pollens, bites and stings etc. High histamine, food allergies , under-methylation and liver congestion seem to all link together.
