The Best Essential Oils for Treating Seasonal Allergies
Spring marks the beginning of allergy season for many people. As temperatures rise and the snow melts, allergens in the environment are exposed, making it difficult for people who suffer from seasonal allergies to enjoy the warm weather and longer periods of sunshine. While these symptoms are not life-threatening in the vast majority of cases, allergic reactions are uncomfortable and inconvenient side effects of the seasonal changes in the environment. Essential Oils and their respective herbs have been used for centuries to support immunity, treat seasonal illnesses, and improve overall wellbeing. Whether inhaled, diffused, or applied topically with a carrier oil, essential oils for allergies make an effective natural treatment as the seasons change. Read below to identify the common symptoms of seasonal allergies, and the best essential oils to support your health.
Common Allergy Symptoms
The medical term for seasonal allergy symptoms, also known as hay fever, is allergic rhinitis. This occurs when the body’s immune system becomes sensitized and overreacts to something in the environment. In most cases, allergic reactions are uncomfortable inconveniences. However, for some, certain allergies can trigger life-threatening reactions, such as inflammation and shortness of breath.
People with seasonal allergies typically experience symptoms from late winter to end of spring, or even in late summer and into fall. The most common symptoms of seasonal allergies include:
- Sneezing
- Runny or stuffy nose
- Watery and itchy eyes
- Itchy sinuses, throat, or ear canals
- Ear congestion
- Postnasal drainage
The most common causes of seasonal allergic reactions are:
- Pollen
- Dust
- Mold
- Insect stings
- Animal dander
Wind-pollinated plants such as trees, grasses, and weeds are the most common triggers of seasonal allergies, and are most prominent during the spring months leading into the summertime. While it is possible for people to experience allergic rhinitis year-round, it is less common during the winter. There are numerous treatments available on the market that can alleviate the season’s most prominent allergies. However, the best essential oils for allergies possess anti-inflammatory, antimicrobial, and antioxidant properties that can support immunity and ease flare-ups in the body. If you suffer from seasonal allergies, consider the following essential oils, so you can relish in the natural wonders of the new season.

The Best Essential Oils for Clearing Allergies
Essential oils are organic, concentrated, highly volatile, hydrophobic liquids that naturally occur within and are secreted by tiny structures located in a plant’s various parts – the seeds, grasses, roots, barks, stems, leaves, fruits, flowers, resins, zest and wood of plants. They are also referred to as volatile oils, ethereal oils, or aetherolea. Despite the word “oil,” they feel less viscous than oil, having more of a watery texture.
Inhaling the scent of a flower equates to experiencing its essential oil’s aroma. These oils were given the name “essential,” because they were believed to capture a plant’s essence, that is its odor and flavor. The nature of an oil depends on the plant itself and on the botanical family and species to which it belongs. An essential oil gets its name from the plant from which it is derived. For example, the essential oil from the Lavender flower would be called Lavender Oil.
The oils contained within the plants are aromatic, lending plants their distinctive fragrance while also promoting their self-protection and pollination; it is likely that oils from a plant’s wood, leaves, and roots help the plant guard itself against attacks from parasites and animals and allow them to adapt to their environments, which are sometimes harsh. A pure essential oil then is the plant’s defense mechanism and is more powerful than the botanical itself due to the concentration of healing compounds collected in the oil.
As already mentioned, an essential oil is an aromatic compound that is volatile in nature, which is to say it is a molecule that rapidly changes states from solid or liquid to a gas at room temperature. The speed with which it changes states is the reason for the name “volatile.” In chemistry, this refers to a substance’s tendency to vaporize readily. This is what quickly transports the aroma of an essential oil through the air, causing it to activate olfactory sensors in the nose. The volatile aromatic compounds also govern the physiological benefits offered by an oil - this is precisely what makes essential oils ideal for use in aromatherapy, a holistic practice that promotes a sense of well-being and harmony of body and mind through the power of scent.
This floral oil is amongst the most popular essential oils due to its relaxing and anti-inflammatory properties, which can soothe specific allergic reactions. A 2014 study demonstrated Lavender Oil’s ability to ease allergic airway inflammation and mucous cell hyperplasia, which are common symptoms of asthma.
Cooling and anti-inflammatory, Eucalyptus Oil is believed to help open the lungs and sinuses, which improves circulation and reduces certain allergic symptoms. Its stimulating, slightly medicinal scent is believed to improve airflow when inhaled. 1,8 Cineole, one of the main constituents in Eucalyptus Oil, is believed to possess anti-microbial, antifungal, antioxidant, and anti-inflammatory properties, while Piperitone is believed to act as a decongestant.
Tea Tree is one of the most versatile and multipurpose essential oil, with its medicinal properties ranging from anti-inflammatory, antibacterial, anti-microbial, antiseptic, and stimulating. Due to its anti-inflammatory and antiseptic activities, Tea Tree Oil may be beneficial in easing symptoms of seasonal allergies. It may also act as a disinfectant when used around the home in natural cleaning solutions. However, Tea Tree Oil may also trigger certain allergies, so conducting a patch test is recommended.
One of the most effective essential oils for treating allergies, Peppermint Oil provides relief for clogged sinuses when inhaled. It may also help to treat symptoms of colds, coughs, asthma, and bronchitis. A 2010 study found that Peppermint Oil possesses soothing and antispasmodic properties, which can ease coughing. Numerous studies have also demonstrated Peppermint Oil’s anti-inflammatory properties, which can soothe symptoms of allergic rhinitis.
