Introduction
The components in geranium may irritate the gastrointestinal mucosa, causing adverse symptoms such as nausea, vomiting, abdominal pain, and diarrhea. These reactions are more common with excessive or long-term use. Some individuals may be allergic to components in geranium, experiencing allergic symptoms such as rash, itching, and swelling. In severe cases, it may even trigger life-threatening conditions such as difficulty breathing and anaphylactic shock.
Generally, the side effects of Geranium include gastrointestinal reactions, allergic reactions, effects on liver and kidney function, effects on coagulation function, and impacts on the endocrine system. If any abnormalities occur, prompt medical attention is recommended. Detailed explanations are as follows:
1. Gastrointestinal reactions: Components of Geranium may irritate the gastrointestinal mucosa, causing discomfort symptoms such as nausea, vomiting, abdominal pain, and diarrhea. These reactions are more common with excessive or long-term use.
2. Allergic reactions: Some individuals may be allergic to components of Geranium, experiencing allergic symptoms such as rash, itching, and swelling. In severe cases, it may trigger life-threatening conditions such as difficulty breathing and anaphylactic shock.
3. Effects on liver and kidney function: Components of Geranium are metabolized and excreted through the liver and kidneys. Long-term and excessive use may increase the burden on the liver and kidneys, leading to abnormal liver or kidney function, manifested as elevated transaminase levels, increased creatinine levels, etc.
4. Effects on coagulation function: Geranium may affect the body's blood clotting function, leading to prolonged or shortened clotting time and increasing the risk of bleeding or thrombosis. Therefore, individuals with bleeding tendencies or those taking anticoagulant medications should use it with caution.
5. Effects on the endocrine system: Some components of Geranium may interfere with the normal function of the endocrine system, causing hormonal imbalances. Long-term use may affect women's menstrual cycles, men's reproductive function, etc.
In addition to the above side effects, individual differences and usage in special populations should also be considered. Different individuals have varying tolerances to Geranium, and some may be more prone to adverse reactions. Meanwhile, special populations such as pregnant women, lactating women, children, and elderly individuals should exercise particular caution when using Geranium, preferably under the guidance of a physician.
