Natural Relief for Seasonal Allergies with Cannabinoid Therapy

As spring arrives in full bloom, many people across the UK welcome longer days and warmer temperatures. But for the estimated 1 in 5 people who suffer from hay fever – also known as seasonal allergic rhinitis – this time of year can be far from enjoyable. Sneezing fits, itchy eyes, nasal congestion, and fatigue are just some of the symptoms triggered by airborne pollen, making daily life uncomfortable and even disruptive. While traditional treatments like antihistamines are widely used, many are now looking into alternative therapies, including medical cannabis, for more natural, long-term relief.

At Mamedica, we explore how cannabinoid-based medicine may provide support for those suffering from seasonal allergic rhinitis.

Causes and Symptoms of Hay Fever?

Hay fever, or allergic rhinitis, is an overreaction of the immune system to airborne pollen. The body releases histamine and other inflammatory chemicals, triggering symptoms such as:

• Runny or blocked nose
• Sneezing and coughing
• Watery, itchy eyes
• Pressure in the sinuses
• Fatigue and brain fog

Pollen levels peak between March and August, but symptoms can persist for months. Some patients struggle despite taking over-the-counter or prescription medications, which may cause side effects like drowsiness.

The Endocannabinoid System and Allergies

The endocannabinoid system (ECS) plays a key role in regulating inflammation, immune response, and homeostasis in the body. It includes two primary receptors:

• CB1 receptors: Mainly found in the brain and nervous system
• CB2 receptors: Found in immune cells and peripheral tissues

Research suggests that activating CB2 receptors with cannabinoids like CBD (cannabidiol) or THC (tetrahydrocannabinol) can help reduce inflammation and modulate immune responses, both of which are central to hay fever symptoms.

How CBD May Help With Hay Fever

CBD is a non-psychoactive cannabinoid with documented anti-inflammatory and antihistamine properties. Studies suggest that CBD may:

• Decrease histamine release from immune cells
• Reduce nasal and sinus inflammation
• Support immune balance and reduce allergic sensitivity

Though more research is needed, these properties make CBD oil a potential supplement for those managing hay fever naturally.

The Role of THC in Allergy Relief

THC, the primary psychoactive compound in cannabis, also has anti-inflammatory effects. In small, controlled doses, it may help reduce:

• Nasal swelling
• Sinus pressure
• Breathing difficulty associated with allergic reactions

At Mamedica, our clinicians tailor THC levels carefully to ensure symptom relief without unwanted side effects, especially for patients new to cannabis-based treatments.
