Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Green tea (Camellia sinensis) has been investigated for its potential anti-allergic properties, including in the context of food allergies. The key bioactive compounds in green tea, particularly epigallocatechin gallate (EGCG), have been shown in laboratory and animal studies to inhibit the release of histamine and other inflammatory mediators from mast cells—cells that play a central role in allergic reactions. Some research suggests that green tea polyphenols may modulate immune responses, reducing the severity of allergic symptoms. For example, animal studies have demonstrated that EGCG can reduce IgE-mediated allergic reactions, and cell culture studies show inhibition of key signaling pathways involved in allergy.

However, clinical evidence in humans is very limited. A few small-scale studies and anecdotal reports suggest that green tea may help reduce symptoms of allergic rhinitis or mild food intolerance, but no large randomized controlled trials have established its efficacy for treating or preventing food allergies in humans. Most evidence remains preclinical, and the translation of these findings to human health is uncertain. As a result, while there is a scientific rationale and some promising preliminary data, the current evidence supporting the use of green tea for food allergies is weak, and it should not be relied upon as a primary treatment. Further clinical research is needed to establish its safety and effectiveness in this context.
