Millions of us suffer from allergies triggered by all kinds of bothersome allergens. Whether they are indoor triggers such as dust or mites, or outdoor sources like weeds or grass, the bottom line remains: It's no fun to have a reaction. We're adding one more weapon to your herbal arsenal. HistaBlock can support the year-round allergy sufferer.

• Provides antioxidant strength to help stabilize mast cells.
• Supports free breathing and may help reduce unpleasantness associated with allergens.
• Provides nutrients that support the respiratory system in its battle against allergens, pollutants and toxins.
• Supports the body's efforts to control inflammation and swelling of mucous membranes.

Stinging Nettle provides well-known support against allergic rhinitis in hay fever sufferers.

Quercetin, a bioflavonoid, has been used for its reputed effects in supporting the respiratory system. It is believed that this antioxidant helps stabilize mast cells, which contain the histamine released during an allergy attack. Breathe a sigh of relief.

Bromelain works as an anti-inflammatory to help reduce the swelling of mucous membranes during allergic reactions.

Fructus aurantia contains synephrine, which helps the body's natural decongestant processes open up the airways. It also may reduce runny nose and watery eyes.

Nature's Sunshine Advantage
Mast cells are responsible for the drastic reactions that occur during seasonal respiratory attacks. HistaBlock is a unique formula that helps stabilize these cells and inhibits swelling that occurs in the mucous membranes.

Recommended Use
For acute concerns: Take 1–2 capsules every two hours as needed, up to 12 capsules a day. As a maintenance measure: Take 1–2 capsules two to three times daily.

Don't take if hypertensive or taking blood pressure medication.

It Works!

I have had allergies since I was born and the hayfever began when I was in grade school, so I always carried a pocketful of tissues to school that my mother would lovingly fold each morning. As I got older I began taking antihistamine pills which stopped the runny nose and itchy eyes, but put me to sleep on my desk. As an adult I found a great product called SN-X that worked so well I could leave the drugs behind. After 10 years of use, they changed the formula and it wasn't the same. A couple years ago I read about HistaBlock so I thought I'd give it a try ... and it worked! I don't even have to take as much of it as I did the SN-X. I love it! No more runny nose and itchy eyes.


    Sinus/Allergy Attack

    "I had an unexpected sinus/allergy attack. It began over the weekend with irritated sinuses and scratchy throat. It escalated on Monday and I took a Claritin, which did nothing to relieve my symptoms. While at work, my HistaBlockarrived. I took two with lunch and two with dinner. I stayed home on Tuesday and took two with each meal. This morning, I'm feeling much better. My symptoms have disappeared."
