What are the possible side effects of using this herb improperly?
The possible side effects of using Pelargonium sidoides improperly include triggering allergic reactions in sensitive individuals, which can manifest as skin rashes, itching, or swelling due to its potential to cause an immune system response.
Additionally, improper use of Pelargonium sidoides can lead to interactions with medications, particularly those that affect blood pressure, blood clotting, or liver function, which may result in adverse effects such as excessive bleeding or organ damage. Furthermore, individuals with asthma may experience severe asthma attacks due to the plant's potential to trigger bronchospasm and increased mucus production. Moreover, using Pelargonium sidoides improperly can cause respiratory depression, particularly in individuals with pre-existing respiratory conditions, as it may exacerbate breathing difficulties and reduce oxygen intake.
This is because the plant contains compounds that can slow down breathing rates and reduce lung function, which can be life-threatening in severe cases.
