Unless otherwise prescribed:
Average daily dosage 2 - 5 g of herb, equivalent to 12 - 30 mg total alkaloids calculated as chelidonine. Mode of Administration Cut herb, herb powder or dried extracts for liquid and solid medicinal forms for internal use.

In animal experiments:
cytostatic, nonspecific immune stimulation. Note: The blood pressure-lowering effects and the therapeutic effectiveness for mild forms of hypertonia (borderline hypertonia) need further investigation.
