With the arrival of each change of season, millions of people once again deal with the same old symptoms: chain sneezing, watery eyes, nasal congestion and itchy throat. The first impulse is usually to open the medicine cabinet and grab an over-the-counter antihistamine.

However, a growing number of specialists in herbal medicine and integrative medicine remember that nature also offers alternatives capable of relieving these symptoms, often with fewer side effects than conventional drugs.

Natural antiallergics are compounds of plant and food origin that help inhibit the release of histamine and reduce inflammation, reducing sneezing or congestion. They act as adjuvants to relieve mild symptoms, with the advantage of not causing the drowsiness typical of conventional medications.

Why look for alternatives

Traditional antihistamines - such as loratadine, cetirizine or diphenhydramine - They block histamine, the substance the body releases during an allergic reaction. They are effective and fast-acting, but they are not free of drawbacks: drowsiness, dry mouth, headaches or, in the case of first-generation drugs, interference with the ability to concentrate.

For those looking to reduce their medication consumption or complement treatment, there are plant options that have been studied for their natural antihistamine and anti-inflammatory capacity.

Five natural anti-allergy:

Quercetin. Present in apples, red onions, grapes and green tea, quercetin is a flavonoid to which various preliminary studies attribute the ability to stabilize mast cells, the cells responsible for releasing histamine. That is why it is popularly known as “the natural antihistamine” par excellence.

Nettle (Urtica dioica). Nettle, traditionally consumed as an infusion, is one of the most cited plants in popular medicine for the relief of allergic rhinitis. It is thought to work by reducing airway inflammation, although high-quality scientific evidence remains limited.

Vitamin C. This antioxidant, present in citrus fruits, kiwis and peppers, participates in the breakdown of histamine in the body. Some specialists recommend incorporating foods rich in vitamin C during the season of greatest exposure to allergens.

Probiotics. Gut health and the immune system are closely related. Various research has explored the role of certain strains of probiotics in modulating the allergic response, although results vary depending on the strain and the person.

Local honey. Although the scientific evidence is mixed and inconclusive, there is a widespread belief that consuming honey produced in the region where you live could help the body “get used” to local pollens, similar to immunotherapy.

An alternative, not an automatic replacement

Specialists agree on a key point: these remedies can be a good complement, especially for mild symptoms or as a preventive measure, but they do not replace a medical diagnosis or the indicated treatment for moderate or severe allergies. People with asthma, severe food allergies, or a history of anaphylaxis should always maintain medical supervision.

Furthermore, “natural” does not always mean “risk-free”: some plants may interact with medications or may not be recommended during pregnancy, breastfeeding, or for people with certain health conditions.

In short, before replacing pharmacological treatment with natural remedies, experts advise consulting an allergist or family doctor. Each body responds differently, and what works to relieve symptoms for one person may not be as effective—or even safe—for another. The key is information and professional support, not improvisation.
