Can I apply geranium (herb) for allergies?

　　Allergies can usually be treated with geranium, but if the condition is severe, it generally should not be applied.　　

　　The main ingredient of geranium ointment is geranium, which has functions of eliminating dampness and detoxifying, as well as astringent and tissue-regenerating effects. It is primarily used to treat eczema, abscesses, boils, and sores caused by accumulated damp-toxin and also has certain therapeutic effects on skin allergies. Additionally, geranium itself possesses multiple functions such as clearing heat and detoxifying, promoting blood circulation to remove blood stasis, which can play a certain role in treating skin allergies.

　　However, it should be noted that if the skin has a severe allergic reaction accompanied by serious symptoms such as redness, blisters, peeling skin, or difficulty breathing, it may be a severe allergic reaction. In such cases, one should not self-administer geranium or any other herbal remedies, but should seek immediate medical treatment. For topical medications, ensure the affected area is clean and dry, and avoid scratching; if the cause of the allergy is unknown, it is recommended to seek medical advice for a clear diagnosis first, to avoid misusing medications and delaying treatment.

　　Maintaining good personal hygiene habits and avoiding contact with known allergens are also important methods for preventing and managing allergic reactions.
