FAQ
Frequently Asked Questions
It depends on the specific plant referred to. 'Kidneywort' can refer to Marchantia, which is a non-flowering liverwort (a bryophyte), or to certain saxifrages, which are flowering plants.
Unlikely. It is a specialized plant, and liverworts like Marchantia are often considered weeds in cultivation. Specific saxifrages might be available from specialist nurseries.
No. Historical use does not imply safety or efficacy by modern standards. Many plants contain toxic compounds. One should never use plants medicinally without expert guidance.
The name comes from the shape of its leaves (resembling a kidney) and the Old English word 'wyrt' for plant or herb, reflecting the ancient 'doctrine of signatures' in herbalism.
