* [[Stinging Nettle]] leaf : An herb called stinging nettle leaf reduces the amount of histamine the body produces, reducing sneezing and itching due to hay fever. Stinging nettle leaf extract in freeze-dried capsule form can be taken in a dose of 300 milligrams daily.
* [[ElderberriesElderberry]] : Active ingredients in elderberry also support the sinuses by discouraging swelling of the mucous membranes. This benefit makes elderberry an excellent tool for supporting health while combating seasonal allergy symptoms. It naturally protects defenses by keeping bacteria in check, and it has also been used to deter sinusitis and nasal congestion
* [[Serrapeptase]] : This natural enzyme supplement offers help for allergies, [[asthma]], [[arthritis]], [[MS]], and other [[inflammatory diseases]].
* [[Spirulina]] holds some promise in the treatment of allergic rhinitis (nasal allergies) and eating spirulina every day significantly improves allergy symtoms.
* Hesperetin/[[Hesperidin]] for Hay Fever : Hesperetin and hesperidin are almost identical except that the latter is bound to a sugar molecule. Research shows that these potent phytonutrients have antioxidant, anti-inflammatory, anticarcinogenic, and cholesterol-lowering actions, and also protect blood vessels against damage. These are just some of the therapeutic side-effects of hesperidin. Hesperidin is also beneficial for allergies and hay fever because of its antihistamine properties. Green vegetables are a source of hesperidin / hesperetin. You can also find them in their highest concentration in citrus fruits like lemons and oranges, especially the white part, or pith. Of course, avoid citrus fruits if you suspect that you are sensitive to them.
*[[Quercetin]] is a bioflavonoid, a phytochemical found in plant foods such as apples, onions, berries, grapes, teas, and red wine that supports the immune system and acts as a natural antihistamine. A normal healthy diet will provide about 25-50 milligrams of quercetin; if you choose to supplement this, be sure to follow the dosage instructions on the bottle.
* [[Amylase]] Possesses antihistamine properties amylase can relieve many kinds of skin problems, such as hives and rashes, contact dermatitis, and allergic reactions to bee stings, bug bites, and poison oak or ivy.* [[Black seed Seed Oil]] : A paper published from Institute for Transfusion Medicine, Charité University Hospital, Berlin, Germany examined the results of four studies on the clinical efficacy of Nigella sativa in allergic diseases including in these studies, a total of 152 patients with allergic diseases (allergic rhinitis, bronchial asthma, atopic eczema) were treated with Nigella sativa oil.
* Carotenoids : In a 2006 study from Public Health Nutrition, scientists found that allergies are less common among people with a high intake of carotenoids (a class of antioxidants that includes beta-carotene, lutein and lycopene).
* [[Caper]]s are rich in the bioflavonoids rutin and quercetin (also found in apples, red onion and tea), both of which have antihistamine and anti-inflammatory properties. Quercetin is particularly effective as an anti-allergy remedy when taken with bromelain; an enzyme found naturally in pineapple.
*[[Peppermint]] tea relieves nasal and sinus congestion. Drink it cold to sooth coughing associated with hay fever and allergies. Spearmint and peppermint help open up airways.
* [[Lavender]] has antiseptic properties in case infection creeps in (calendula is great for this too).
* [[Oregano]] : its carvacrol and rosmarinic acid content are natural decongestants and histamine reducers that have direct, positive benefits on the respiratory tract and nasal passage airflow.
* Collard greens Collard greens contain phytochemicals, specifically carotenoids. This component is well known for easing allergic reactions. To further boost the effects of carotenoids contained in collard greens, allergy stricken individuals should consume the vegetable with a fat source.
*[[Butterbur]] reduces inflammation, blocking histamines and leukotrienes. Studies suggest the herb is effective for relieving sneezing, itchy eyes, sinus congestion and headaches. People allergic to ragweed or chrysanthemum should avoid butterbur.
