Wood anemone

The leaves are antirheumatic, rubefacient and tonic. The plant is sometimes used externally as a counter-irritant in the treatment of rheumatism. The herb is gathered in spring before the plant comes into flower. Various parts of this herb used to be recommended for a variety of complaints such as headaches and gout, though the plant is virtually not used nowadays. A homeopathic remedy has been made from the leaves. Source: https://pfaf.org/
