Love Love Love
I have a horrible hay fever issue throughout the year. Always needed a prescribed medicine for it. Since I started using this product, I haven't taken my allergy medicines at all! Great product with the great price! 100% recommended!

The best!
I always keep Histablock around, but rely on it heavily for spring pollen season. When I’m feeling extra allergic and my normal allergy meds aren’t enough I take Histablock and I feel so much better. It helps me with asthma like symptoms and just feeling extra itchy from pollen.

Cant live without Histablock!
I started taking Histablock about two/three years ago and I honestly can't live without it. I have very sensitive skin that breaks out in urticaria and Histablock is the only thing that helps keep my skin from getting really bad. Its not perfect and I have to take it everyday to keep it in my system but it really, really helps take the edge off my itching and my skin looks better when I stay on it.

A definite light at the end of the tunnel.
I have been taking HistaBlock for only about a month now and I'm noticing a lot of the histamine symptoms I was having have resided. It is hard to tell exactly the job it is doing because I am also dealing with MCAS & other issues but I am gratefully no longer having stabbing nerve pain going down my legs & into my feet so this must be giving blessed relief for this. Thank you for this effective product. This is a long journey, but I have hope. Doe.
