Histablock Worked Wonders

Firstly I tried this product at a friends place down the line. I had severe allergies & nothing with me, within an hour the itchy eyes, sneezing & runny nose had gone. I have since given some to my grandson, who has asthma, allergies & does a lot of fitness with his chosen sport. He took Histablock an hour before training & got through 2 hours without using his primary inhaler. I definitely recommend this product to those who suffer with allergies.

Great for histamine intollerance

I bought this to help with a nasty case of histamine intolerance which has lead to hives and severe eczema. Definitely helped reduce the symptoms and probably more so than the antihistamines that my doctor gave me. I would imagine that it would help with seasonal allergies too. Highly recommended.
