Oolong Tea Histamine Information

Oolong tea, a traditional Chinese tea, occupies a middle ground between green and black tea, sharing properties of both. When it comes to impacting histamine levels, there isn't a substantial amount of research specifically targeting Oolong tea. However, and according to a study published in "Inflammation Research", tea in general, including Oolong tea, is observed to inhibit the release of histamine [1]. As tea contains polyphenolic compounds like flavonoids, these compounds possess antioxidant, anti-inflammatory, and anti-tumor properties [2]. They also demonstrate anti-allergic properties by reducing histamine release [2]. Although tea can generally inhibit histamine, it's important to consider that the caffeine content in Oolong tea may lead to some difficulties for those who suffer from histamine intolerance, as caffeine is a known histamine liberator [3]. Looking at the ingredients of Oolong tea, it mostly involves tea leaves. Tea leaves, regardless of being green, black or oolong, contain a compound named theobromine which reportedly helps in reducing the histamine level, because of its diuretic, stimulant and relaxing effect [4]. However, more research is needed in this specific area to confirm these findings. This information highlights the varying impact of Oolong tea on histamine level. However, individual responses may substantially differ, and the effects may vary on the degree of histamine intolerance present in the consumer.
