Addressing Seasonal Allergies Sponsored by Quicksilver Scientific

Watery red eyes, nasal congestion, sneezing, and coughing – when your waiting room is full of patients with these symptoms, you know that allergy season has arrived! Seasonal allergies are on the rise, with 8% of U.S. adults suffering from seasonal allergies in the spring, summer, and fall.1 Rising levels of CO2 from climate change are causing plants to produce pollen more vigorously, lengthening the intensity and duration of allergy season.2 Natural antihistamines can offer dramatic relief, balancing your patients’ histamine response and allowing them to enjoy the spring and summer months without relying on over-the-counter allergy medications.

What are Seasonal Allergies?

Seasonal allergies, sometimes referred to as “hay fever” or allergic rhinitis, are allergy symptoms that occur during specific times of the year when outdoor trees, grasses, weeds, and molds release pollen and spores into the air. In some people, plant pollen and mold spores activate the immune system, causing mast cells and basophils to release histamine and other inflammatory mediators.3,4 These mediators dilate blood capillaries and contract smooth muscle, causing red, puffy eyes, sneezing, and coughing.

The Problem with OTC Allergy Medications

Research indicates that 75% of seasonal allergy sufferers rely on over-the-counter (OTC) allergy medications.5 Despite their popularity, these drugs are not without risks! Decongestants can precipitate hypertensive crises in people with undiagnosed hypertension; this is extremely concerning, given that 75 million Americans have hypertension and over half are unaware of their condition.6,7

Antihistamines, which reached a whopping 6.89 billion dollars in sales in 2016, may also be harmful.8 Antihistamines such as Benadryl target cholinergic receptors of the nervous system; long-term inhibition of these receptors is linked to impaired memory consolidation and dementia.9,10

If OTC drugs aren’t the answer, how can you best serve your patients suffering from seasonal allergies? Natural antihistamines offer a safe, effective alternative to decongestants and antihistamines for balancing the body’s histamine response.

Histamine-Taming Nutraceuticals

Flavonoids

Flavonoids are polyphenolic plant compounds ubiquitous in fruits and vegetables. Two flavonoids – quercetin and luteolin – have particularly powerful anti-allergy effects.

Quercetin, found in onions, berries, and apples, inhibits histamine release from mast cells and basophils. In fact, it is more effective than Cromolyn sodium, a mast cell-stabilizing drug, for inhibiting the release of histamine and inflammatory cytokines from mast cells!11,12 Quercetin also suppresses the formation of IgE antibodies, which mediate allergic sensitization.13

Luteolin, found in celery, thyme, and bell peppers, also has potent antihistamine activity.14 It decreases inflammatory cytokine production and immune cell infiltration in the lungs, balancing the body’s response to environmental allergens.15

Vitamin C

While vitamin C deficiency is associated with an increased risk of allergies, restoration of healthy vitamin C levels rapidly decreases histamine.16 Vitamin C alleviates histamine excess by destroying the structure of the histamine molecule.17

DIM

Diindolylmethane (DIM) is a sulfur-based compound found in cruciferous vegetables and a potent activator of the Nrf2 antioxidant system. Nrf2 increases the activity of antioxidant and detoxification genes and is beneficial for suppressing allergic lung inflammation.18,19

DIM also decreases histamine by balancing hormones. Estrogen stimulates mast cells to release histamine and downregulates the DAO enzymes responsible for degrading histamine; excess estrogen can, therefore, trigger allergy symptoms.20,21 By balancing estrogen, DIM regulates histamine, providing further relief of seasonal allergies.

Importantly, xenoestrogens such as BPA and phthalates also exacerbate allergies by influencing histamine activity. DIM has a protective effect against xenoestrogen-induced estrogenic signaling, further balancing the histamine response.22

Liposomal Delivery for Rapid Histamine Relief

Research indicates that liposomal delivery systems significantly enhance the bioavailability and uptake of quercetin, luteolin, and vitamin C.23,24 Liposomal delivery is thus an optimal strategy for rapidly delivering antihistamine nutrients to your patients' cells, balancing their histamine response to seasonal allergens.

Allergy season doesn’t have to be a struggle for your patients! With the help of potent natural antihistamines, your patients can achieve a more balanced histamine response and relief from seasonal allergies.
