This actually works!
I have purchased many other items to no avail. I was desperate, hives and uticaria with red and puffy eyelids, lips and intense whole body itching from pollen. I have EDS and mast cell issues. No allergy meds. work for treatment of mast cells. This was pricey but I read through the reviews and bought it. After a month and a half of absolute misery with nothing that helped at all, I have finally found relief. I would have paid double. This formula actually works and if you're really suffering, it is well worth the price.

Decent product
Appreciate a good researched product from a reputable company. And appreciate the easy to find allergy information. Unsure if it made a difference for me though

Helps manage MCAS histamine flares
My functional medicine doctor recommended HistaQuel to manage my histamine reactions. It helps a lot. I've been taking it regularly for a couple years.
