Hi there,
I was just trying to find out more about hives as my husband has it and it only started about 1-1/2 years ago. Through some experimenting and talking to health consultants, we found that taking "pine bark" or "pycogenol" on the onset of hives outbreak does help. I guess the other way was for my hubby to continue with the doctor's prescription - which is anti-histamine medication.
Hope this information helps.
