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.

The best sandals EVER
Size: 8, Color: White Khaki
These flip flops are so so so comfortable. I have bunions and a nerve problems so finding the right shoe is an issue for me. These are the most comfortable flip flops I have ever had the pleasure to wear. I cannot recommend enough how good and natural these feel. They are flexible yet supportive. So far on vacation they have walked miles with me and still in great condition. They are so naturally light weight. I will be buying again for sure

Most comfortable flip flops ever! From day 1!
Size: 7.5, Color: White Khaki
These are hands down the most comfortable flip flops ever. There is no 'break-in' period. The fabric is so soft you forget it's there and it doesn't rub between your toes at all. By the second full day of wear, the foam was starting to conform to the contour of my feet. They feel and look great. The bottoms have a nice triangle tread pattern on them instead of being totally flat so I'm hoping they will still get traction on wet floors like pool areas etc. I got them after nearly doing a split again in my old ones that were a safety hazard poolside.

Nice flip flops
Size: 7, Color: Grey
Nice looking flip flops. They feel good and well made, but I've only worn them for a few hours. The material that goes over the feet is almost too stretchy. I hope they don't stretch out more. I have wide feet and these fit great, true to size. I like the grey color.

Love the material!
Size: Large, Color: Black
Very soft and beautiful material. The size was perfect. It works well for layering and can also be dressed up. It is not clingy at all. The quality is great.

Worked well for my needs!
Size: X-Large, Color: Black
Nice thick material. I think these could be workout shirts or regular day attire. Soft, wash well, nice stretch, and arm pit gaps aren’t a so wide they look silly or sloppy. Good value for the money. True to size as well.
