Overview

Block the havoc of pollen and seasonal irritants with the potent herbal HistaBlock® blend!

HistaBlock® provides nutrients that support healthy respiratory function as the body battles irritants, pollutants and toxins.

HistaBlock® also supports the body's efforts to maintain mucous membrane health, especially when seasonal irritants are plentiful.

This unique herbal blend features Stinging nettle, Quercetin, Bromelain and Bitter Orange to provide natural help with seasonal irritants, so you can breathe easier.

Powerful antioxidants in this formula help stabilize mast cells to support the health of the airway passages and mucous membranes. They also offer natural help with seasonal irritants.

Mast cells are a type of white blood cell that play an important role in many inflammatory responses such as allergic reactions.

HistaBlock® stands out for two compelling reasons:

  • The whole is greater than the sum of its parts — each ingredient strengthens this blend, providing nutrients to support respiratory health, fight free radicals, and help maintain clear nasal passages.
  • HistaBlock® nettle grows wild in the Albanian mountains and is carefully hand-harvested.

Don’t let seasonal irritants and pollutants interrupt your life.

Support better breathing with HistaBlock®…only from Nature’s Sunshine!

Benefits

  • Respiratory system support, especially during seasonal changes
  • Promotes healthy airways for better breathing
  • Supports mucous membranes
  • Neutralizes free radicals

How It Works

Stinging Nettle

Stinging nettle provides well-known support against seasonal airborne substances. Nettle has a long history of supporting respiratory health, helping to reduce sneezing and itching caused by seasonal irritants. Researchers believe nettle may work by helping to lower the amount of histamine the body produces in response to an allergen. Interestingly, the medical term urticaria (commonly called hives) is a close derivative of the Latin name for nettle, Urtica dioica. And, did you know that the nettle plant can help alleviate the very skin reaction it causes? Making a tea of nettle root to wash irritated skin can offer immense relief to the affected area. Leave it to nature to offer up a quick herbal solution!

Quercetin

Quercetin is a powerful antioxidant flavonoid found in apples, onions, black tea, and the Sophora japonica tree. Quercetin has been used for its reputed effects in supporting the respiratory system, promoting immunity, and fighting free radicals. Quercetin may help stabilize mast cells that release compounds when exposed to irritants, helping to combat seasonal threats. Quercetin also helps vitamin C work longer.

Bitter Orange

Bitter orange is commonly used in Traditional Chinese Medicine (TCM) to reduce excess phlegm and help relieve respiratory congestion. Bitter orange is said to help break up mucus congestion. Bitter orange contains synephrine, which helps the body support open airways. Synephrine possesses properties somewhat similar to the alkaloid ephedrine (used in over-the-counter decongestant preparations) in providing respiratory support, but it acts much more mildly in the body. Bitter orange also provides other nutrients for respiratory support.

Bromelain

Bromelain is a protein-digesting enzyme mixture derived from the fruit, juice and stem of the pineapple plant. Bromelain may also promote a healthy respiratory tract. Bromelain works to help reduce the swelling of mucous membranes during times of respiratory stress. It also helps to thin and break up mucus to maintain clear nasal passages and improve respiratory function. Plus, bromelain supports immune function, helps reduce swelling and discomfort, and promotes a healthy inflammatory response.

Ingredients

Proprietary blend of Nettle leaves, Quercetin (from Sophora japonica fruit), Bitter Orange fruit and Bromelain (from pineapple fruit).

HistaBlock
I used to take HistaBlock about 35 years ago when my mother was a distributor. She took ALJ and HistaBlock regularly. I have allergies now that cause my eyes and eyelids to itch, swell, become inflamed, flake, burn, etc. I remembered HistaBlock after trying over the counter products to no avail. HistaBlock works and I like the ingredients much better! I will probably order Seasonal Allergy next! Thanks Mom and thank you Nature's Sunshine! Ordering from the website is easy and convenient.

charged shipping on my return
I ordered HistaBlock from Nature's Sunshine but the delivery was slow and then I realized I didn't need it but was charged the full shipping price to return it ($7) so on a $27 purchase, I only got $20 back. I think the company could have at least split the shipping with me. I won't be ordering from this company again.

AL pollen MUST HAVE
I live in AL and have always struggling this time of year, pollen season. My herbalist recommended this product to me and it's been great! Along with a few other remedies, I've not had complete blockage of my nose/sinuses this season and that normally happens to me every year. It's also helped with my itchy eyes and throat due to a pollen allergy. Will always keep this on hand now. Love that it's a natural antihistamine!

Haven't received mine
First time ordering histablock and order placed was successful until the following day I was notified that they didn't know it was out of stock. Have not received any update on when it is back and shipping out or delivery days and times. But of course was still charged for my order. Received an email today saying, "Hope your enjoying your histablock.. click to rate" we'll haven't tried it yet and haven't received it. So hopefully I'll be able to get it real soon to try it and form and opinion on whether it works or not.

Best allergy relief ever!
Just herbs, no side effects, no sleepiness or lethargy. When allergy season hits, I up the dose to about 3 caps 3 times a day, which works well for me. Other times just 3 once a day is enough. Sometimes I combine it with some spleen activator, so the two support each other. Seriously, best ever seasonal allergy relief!
