Recent research has shown that the plant might have anti-tumour activity, though Hemp Agrimony also contains pyrrolizidine alkaloids that can cause damage or cancer to the liver. The roots are diaphoretic, laxative and tonic. Recently the plant has been found of use as an immune system stimulant, helping to maintain resistance to acute viral and other infections. A homeopathic remedy is made from the leaves. It is used in the treatment of influenza and feverish chills and also for disorders of the liver, spleen and gall bladder.
