  • Supports Immune Balance in Hypersensitive Individuals
  • Supports Sinus and Respiratory Health
  • Promotes Normal Viscosity of Mucus
  • Clears Nasal Passages


Ingredient Benefits


Quercetin has strong antioxidant activity and has been shown to support immune health by mediating the release of inflammatory compounds including leukotrienes and prostaglandins. Quercetin is known for its ability to stabilize mast cells, diminishing the release of histamine, the compound known to cause hypersensitivity reactions during seasonal changes.

Stinging Nettles Leaf Extract

Stinging nettles leaf is a plant that has been shown to balance immune response, specifically in the airways and nasal passages. Studies have shown that the extract of stinging nettles leaf balances a variety of inflammatory activities that affect respiratory health.


Bromelain is a plant enzyme naturally found on the stem and fruit of the pineapple plant. Bromelain is a proteolytic (protein-digesting) enzyme that aids in in the breakdown of large protein complexes, including antigenic compounds, and has been shown to enhance the absorption of quercetin. Bromelain has been shown to reduce circulating allergenic protein complexes associated with hyper-immune sensitivity and seasonal discomfort.

N-Acetyl Cysteine

N-acetyl cysteine (NAC) is an amino acid precursor to one of the most important antioxidants in the body, glutathione. Both glutathione and NAC help reduce the viscosity of the mucus allowing for clearing of the airways and improved respiratory health.

Vitamin C

Vitamin C cannot be synthesized by humans and is therefore an essential nutrient that must be consumed in the diet. Among its numerous health-promoting properties, vitamin C is an essential vitamin that supports the immune system and is also a potent antioxidant. When the body is under a significant amount of stress, vitamin C is excreted rapidly. Vitamin C has many immune boosting properties, but is distinctively beneficial for individuals with seasonal discomfort because of its ability to deactivate histamine.

    Not doing well I am confused. I bought D Hist and the Flora Symmetry. Things were going ok for a couple of days but then one evening I started itching all over and had to take Benedryl to stop it. Now I don’t know which one it was, so I’ve stopped taking both. I am afraid to have a bigger reaction. I was then back to Zyrtec and taking magnesium calcium liquid and a different low histamine probiotic trying to fix my stomach, food intolerances, and eczema etc but then I got constipated. And even though I can have a tendency to constipation, I eat enough vegetables and drink enough water that it rarely happens. I’m just totally confused. I stopped everything and just taking Zyrtec again and eating gluten free whole grains and vegetables and fruit, and my bowels are feeling much better. It’s almost like they were swollen and I wanted to go but couldn’t. I need help! I feel like a mess at only 50. I ordered the whole seminar and all of the supplements to get started but now back to nothing.

    wonder drug the difference D-Hist made for me was astounding. I was taking numerous supplements without even knowing if they worked, just cuz I read them online and was desperate – and they added up to a lot of time and money wasted. D-hist did way more than I expected because I saw a difference in less than 2 weeks and was able to eat foods I definitely couldn’t before – so I am SURE it’s helping. I am ordering 2 bottles at once now usually (saves me shipping!) and I have been able to drop most of my other supplements. That D-Hist is truly a wonder-drug!

    A real life-saver! Starting D-Hist requires a loading dose - I think it's to get your body's histamine levels down quickly. It takes a week or so to kick in, but boy when it does it's so helpful! My histamine tolerance is WAY better. I'm able to eat foods I couldn't before, and more of the foods I could eat without any reaction. It's been so helpful in making my diet and life easier! Less questions and skepticism and more eating and enjoying time with the family. A real life-saver! Will definitely be buying again!

    Hives and redness GONE! My hives are gone!!!! I no longer look like a puffy, hive-covered, rashy and red human being who looks like I just got stung by bees. I didn't even know about histamine issues until I found this website!!! My doctor told me they were seasonal allergies and there was nothing I could do, and then my allergist told me I didn't have allergies. How confusing is that!? I would love to show him that D-hist was an all-natural product that fixed all the problems he couldn't. But I have a feeling he wouldn't appreciate that so much... HIVE FREE AND LOVING LIFE!

    Symptom Free! When I was purchasing D-hist, I must admit I was cringing a bit at the price. I had previously tried everything from a raw all natural diet to every alternative treatment you can think of and NOTHING changed things. Anyway I ordered D-hist and felt some mild relief on the first day I took it but thought it might be a coincidence or placebo effect, so didn't get too excited. To my surprise and delight, the relief continued to improve! Hives, itchiness, congestion and rashes, all gone! I even feel more energetic!! I now feel like I'm living symptom free on a daily basis. I forgot this was even a possibility but my family is happy to have me back and I'm enjoying the time with my children again. It also had ZERO side effects. No drowsiness or What prescription drug or doctor can give you that? Also, I don't have to take this product every day anymore. I started out with a higher "loading dose" and then it levels off to a point where I was maintaining, and it's been a few months now and I take it every few days or if I know I'll be exposed to *what used to be* irritants. Anyway, I'm glad I didn't let the price put me off from ordering D-hist because now I don't know what I'd do without it. There is nothing that can beat getting a second lease on life, and for me it was inside this silly little bottle.
