Ragweed
Have noticed my seasonal CHs coincided with ragweed season. Started taking Zyrtec and it has definitely cut down on my CHs and also on shadow headaches. My Accupuncturist said that people who have a lot of histamine issues also have a lot of gut issues. This is true for me. He's going to look into some herbal recommendations. I also started on homeopathic Histaminum Hydrochloricum 30C
