As Dr Kara explains, hives are caused high histamine, which is often the result of an allergic reaction, but not always.

We discuss identifying the most common allergies so you can eliminate those. We also examine non-allergic factors of hives, like autoimmune disease, and how to mitigate those. There are steps you can take to counter the histamines that flood your system and cause these uncomfortable reactions.

What steps do you take to deal with your hives? Let me know in the comments!

“It’s up to us to figure out two things. One – we want to figure what the triggers are, and two – we want to balance the immune system so we stop having those reactions altogether.” [3:45]

“A low histamine diet is probably going to be the best for someone who’s got some gut disturbance.” [8:08]

“As soon as you go on a good supplement, a good antihistamine immune balancing supplement protocol and work on your diet, you’ll be able to step away from relying on those medications.” [14:04]

“Treating your gut, taking botanical antihistamines, lowering overall inflammation, and changing your diet. If you respond to those, that’s your diagnosis and your cure.” [16:05]
