Seasonal allergies are common, affecting nearly 10-30% of adults and up to 40% of children worldwide. While there are multiple ways to prevent them including consumption of antihistamines, using saline nasal rinse and eye drops, it is often suggested that staying indoors is one of the best precautionary measures. Allergies occur when the immune system reacts to harmless substances like pollen, dust, or animal dander. In allergic individuals, exposure to these allergens triggers the release of histamine—a chemical responsible for symptoms such as sneezing, itching, and congestion. Antihistamines work by blocking histamine activity, alleviating these symptoms.While many over-the-counter (OTC) medications act as antihistamines, certain natural remedies, including vitamins and plant extracts, may also help manage allergies. Here's everything you can consume to manage seasonal allergies: 1. Vitamin CVitamin C, found in citrus fruits, berries, and leafy greens, is a water-soluble vitamin that supports wound healing and infection management. A 2023 review highlighted its potential to ease allergic rhinitis symptoms like sneezing and itching. For those with vitamin C deficiencies, supplements may be recommended, but dietary sources are generally preferred.2. ProbioticsProbiotics are beneficial microorganisms that promote gut health and may help reduce allergy symptoms. Foods like yogurt, sauerkraut, kombucha, and tempeh are rich in probiotics. A 2021 study suggested that probiotics might alleviate symptoms of seasonal allergies, asthma, and atopic dermatitis. Incorporating more probiotic-rich foods into your diet could offer additional benefits.3. Stinging NettleStinging nettle, a flowering plant native to parts of Asia and Northern Africa, has been explored as a natural antihistamine. A 2009 study suggested its potential to reduce allergy symptoms, though subsequent research, such as a 2017 study, indicated its effects might be comparable to a placebo. Stinging nettle is available as tea or supplements in health stores.4. QuercetinQuercetin is an antioxidant found in onions, apples, grapefruit, and okra. Research from 2022 suggests it acts as an antihistamine, reducing allergy symptoms effectively. While quercetin supplements are available, consuming it through a diet rich in these fruits and vegetables is a healthier choice.5. BromelainBromelain, a compound found in pineapples, is known for its anti-inflammatory properties and ability to relieve respiratory distress associated with allergies. A 2023 study emphasized its potential effectiveness against sinusitis, a common allergy-related condition. Experts recommend eating fresh pineapple rather than relying on supplements.6. ButterburButterbur, a marsh plant in the daisy family, may offer relief from seasonal allergies. Research in 2023 confirmed its safety and efficacy for treating allergic rhinitis, while earlier studies also suggested benefits for migraine management. Butterbur is available as an oil extract or supplement.Medicinal Options for AllergiesIf you are still troubled with allergies, then over-the-counter and prescription medications would be the best option you can follow. Common OTC options include antihistamines like Benadryl and Chlor-Trimeton. Prescription treatments may involve Corticosteroids (e.g., prednisolone) for inflammation, Leukotriene receptor antagonists (e.g. Montelukast) to reduce allergic reactions or Decongestant nasal sprays (e.g., oxymetazoline) for temporary relief.
