Here’s what you already know: Fall is one of the worst times of year for allergy symptoms. What you may not know, however, is that allergies are actually disorders of the immune system — they occur when the body overreacts to harmless substances and produces antibodies to attack the trigger. This then leads to inflammation, which is the leading cause of seasonal allergy symptoms.

All this sounds scarier than it is. The truth is that treating the root cause of allergy symptoms — the immune system — can often stop seasonal allergy attacks before they start. Conventional treatments for seasonal allergies, on the other hand, only mask symptoms, acting more like a Band-Aid than a real solution. And, unfortunately, many often come with a list of side effects, including drowsiness. The good news? The following all-natural supplements work to reduce inflammation, boost the immune system and treat the true cause of fall allergies:
1. Probiotics
Probiotics modify the intestinal flora in the gut, support the immune system and can alter the natural course of an allergy. Studies have shown that probiotic supplementation has a clinical benefit for children suffering from allergic airway conditions such as asthma and allergic rhinitis, or allergies that affect the nose. Probiotic foods including sauerkraut, kimchi, kombucha and yogurt are also extremely beneficial since their fermentation process creates beneficial bacteria that are similar to the organisms found in probiotic supplements. And just like probiotic supplements, these fermented foods boost the immune system and help to relieve allergies.
2. Vitamin D
Research shows that vitamin D exerts profound effects on immune functions involved in the development and course of allergies. A study published in the journal Clinical and Experimental Allergy found that correcting vitamin D levels in those who are deficient has beneficial and even protective effects in patients with allergies, as well as children at risk for developing them.

3. Quercetin
Quercetin is a bioflavonoid that is found in red wine, grapefruit, onions, apples, black tea and, in lesser amounts, leafy green vegetables and beans. It has anti-inflammatory and antioxidant activity, and inhibits the growth of histamine, which can trigger an allergic response. Research also shows that quercetin blocks substances involved in the development of allergies and therefore can reduce allergy symptoms. Quercetin is a safe, natural therapy that may be used as a primary treatment or in conjunction with conventional methods of treating seasonal allergies.
4. Stinging Nettle
Over the years, researchers have collected plenty of data to prove that stinging nettle — a plant named for the prickly hairs that grow on its leave and stems — is effective against seasonal allergy symptoms and can be used to treat anaphylaxis, migraines, cluster headaches and allergic arthritis. These benefits come from the plant’s anti-inflammatory qualities, as well as the histamine it contains, which, ironically, can be beneficial in counteracting severe allergic attacks. A rigorous study of 69 allergic arthritis patients noted a significant benefit with stinging nettle versus using nothing, while another showed that stinging nettle suppressed some pathways related to allergic rhinitis.
5. Butterbur
Butterbur is an anti-inflammatory herb that has been shown to help relieve symptoms of seasonal allergies. One study of 125 people with hay fever in Switzerland found that butterbur extract was as effective as Zyrtec. Butterbur is also especially helpful when you don’t want your allergy medicine to put you to sleep.
6. Astragalus
Astragalus is an herb with a long history of use in traditional Chinese medicine. It boosts the immune system, reduces inflammation and has been used to treat chronic asthma. Research shows that astragalus also has anti-fatigue effects and can improve endurance, which may be helpful for those who feel run down from seasonal allergies. I recommend astragalus to reduce seasonal allergy symptoms such as a runny nose, sneezing and itching.
7. Peppermint Essential Oil
Because peppermint acts as an expectorant and has the power to discharge phlegm and reduce inflammation, peppermint oil can be used to unclog the sinuses and relieve scratchy throats. A study published in the European Journal of Medical Research found that peppermint can be used for the treatment of chronic inflammatory disorders such as bronchial asthma, colitis and allergic rhinitis. To use it, combine peppermint oil with a carrier oil (like coconut) and apply it to your skin, or swallow one to two drops daily.
8. Eucalyptus Essential Oil
Eucalyptus oil produces a cold sensation in the nose that helps to improve airflow, opening up the lungs and sinuses. Citronellal, one of the key components of eucalyptus, has pain-relieving, anti-inflammatory, expectorant and cleansing properties. Diffuse eucalyptus at home or apply a few drops of it to your chest to open up the airways and relieve congestion.
9. Lemon Essential Oil
Lemon oil is one of the best essential oils for allergies because it supports lymphatic system drainage, inhibits the growth of bacteria and boosts immune function. When you add one to two drops to water, lemon oil can also be detoxifying by stimulating the liver and flushing out toxins that can cause inflammation. Lemon oil can also be used to disinfect your home from allergens lingering on clothes and other surfaces.

10. Local Honey
In a 2011 randomized, controlled study in the International Archives of Allergy and Immunology, patients who consumed honey had significantly better control of their allergy symptoms than those on conventional allergy medications. The honey-eaters also had fewer days with severe allergy symptoms and took fewer antihistamines compared to the control group. Why? Local honey is known as an effective long-term treatment for allergy symptoms because it is believed to contain small amounts of the local pollen that is likely causing the reaction. Over time, consumption of local honey thus creates a higher tolerance to the pollen. I recommend consuming 1 to 2 tablespoons per day to decrease pollen sensitivity, reduce congestion and heal itchy, watery eyes and runny noses.
