Can Geranium herb treat allergies?

Generally speaking, Geranium has a certain effect in treating allergies. The detailed analysis is as follows:

Geranium contains flavonoids, tannins, and other components that have anti-inflammatory and astringent effects. It may help alleviate superficial allergic symptoms and possesses various therapeutic effects, including clearing heat and detoxifying, promoting blood circulation to remove blood stasis, and astringent hemostasis. Among these effects, its ability to clear heat and detoxify, along with its astringent and hemostatic properties, may serve as an auxiliary treatment for certain allergic symptoms such as skin redness and itching.

However, due to individual differences in physical conditions and the severity of allergies, the effectiveness of Geranium may vary from person to person. It is not recommended for specific groups, such as pregnant women and individuals with spleen and stomach deficiency cold syndrome. Prior to use, consultation with a doctor is advised to ensure appropriate usage based on one's own health condition. During use, closely monitor local skin reactions, and if symptoms such as worsening redness, swelling, or itching occur, discontinue use immediately and seek medical attention.

Geranium may also cause side effects such as nausea and vomiting, abdominal pain and diarrhea, rash, central nervous system disturbances, and suppression of the hematopoietic system. If any adverse reactions occur, seek immediate medical attention for appropriate treatment.
