Hibiscus Iced Tea Histamine Information

Hibiscus iced tea, a popular refreshing beverage, is typically made from dried hibiscus flowers steeped in water often along with added sweeteners and lemon juice. Regarding its impact on histamine levels, academic studies and concrete information on this specific topic seem to be scarce. However, a dive into its primary ingredients provides insights. Focusing on hibiscus, research suggests that its extract has exhibited anti-allergic properties, including the inhibition of histamine release from mast cells in rats. This indicates that hibiscus might play a role in lowering histamine levels, but this effect in the context of humans and regular consumption of hibiscus tea remains uncertain due to a lack of direct studies (1). On the other hand, added lemon juice can potentially act as a histamine liberator, as it's a type of citrus fruit. These fruits are known to possibly stimulate the release of histamines, potentially counteracting any antihistamine effects hibiscus might have (2). The sweeteners and any additional ingredients used in hibiscus iced tea preparation should also be taken into account, as certain sweeteners might affect histamine levels. However, no concrete information regarding their potential imapct is available from current research. In conclusion, potential effects of hibiscus iced tea on histamine levels are quite complex, influenced by variables such as the specific ingredients used and individual reactions to these ingredients. Further research is required to fully understand these relationships. 1. Sai Ram., & Ram, M. (2003). Anti-allergic actions of Hibiscus rosa-sinensis Linn.
