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

  • Supports respiratory function, especially during seasonal changes
  • Promotes healthy airways for better breathing

HOW IT WORKS

HistaBlock® provides nutrients that support healthy respiratory function as the body battles irritants, pollutants and toxins.
Stinging nettle provides well-known support against seasonal airborne substances. This formula provides antioxidant strength to help stabilize mast cells.

The antioxidant quercetin has been used for its reputed effects in supporting the respiratory system. Quercetin may help stabilize cells that release compounds when exposed to irritants.
Bromelain is an enzyme that works to help reduce the swelling of mucous membranes during times of respiratory stress.
Bitter orange contains synephrine, which helps the body support open airways.

WHY OUR HISTABLOCK®?

HistaBlock® stands out for two compelling reasons: 

  • The whole is greater than the sum of its parts. Each ingredient strengthens this blend. Nettle has a long history of supporting respiratory health. Bitter orange adds other nutrients for helpful support. Quercetin fights free radicals and supports respiratory health. And bromelain helps maintain clear nasal passages.

  • HistaBlock® nettle grows wild in the Albanian mountains. Our partner there has a specially trained team that carefully traverses the hills, collecting these precious leaves while protecting the biodiversity of the region. They ensure crop sustainability by closely monitoring the harvest and proudly employ women in positions throughout the company. 

THE STORY BEHIND HISTABLOCK®

Want more “history”?
Nearly 3,000 years ago, people living in the area of Denmark used cloth made from nettle to wrap their deceased relatives. Much more recently, nettle fiber was used in the making of uniforms for German soldiers during World War I. Today it grows all over the globe, even in remote places like Hawaii, Taiwan and the Canary Islands. Apparently, nettle fans brought their crop with them wherever they went.

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!

Don’t get “stung” by respiratory challenges. Support them with HistaBlock®…only from Nature’s Sunshine.

RECOMMENDED USE

Take 2 capsules with a meal twice daily.

Great for walking all day at work as well
Size: X-Large, Color: (001) Black / Black / White
I walk approximately 10 miles a day at work, in a manufacturing setting. On concrete with steel toe shoes. My feet have been begging me to change from the socks that I have worn for years. I have worn these other name brand socks for probably 10 years. So, change was obviously something I had to be pushed into. I got on Amazon and searched for training socks. I read the description. Glanced at the reviews. I decided to move forward with purchasing these. I could not have been happier. My feet began feeling better immediately. And the priced was very reasonible.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!
