Please read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.

Enhanced precautions for this plant: No reliable tradition of internal use exists for this plant; ingestion is not recommended without the advice of a qualified professional. Aquatic plants may accumulate pollutants, metals, or microorganisms present in their environment, which poses an additional health risk. Do not confuse with other wetland plants of similar appearance, some of which may be toxic. Any use, even external, should be preceded by medical or experienced herbalist advice, due to the lack of reliable documentation on this species.
