Source of validity: Traditional
Rating (out of 5): 1

American Liverleaf (Hepatica americana) has a long history of traditional use by Native American tribes and early European settlers in North America for a variety of ailments, including as a remedy for colds and respiratory issues. The use of American Liverleaf for cold prevention and treatment is documented in ethnobotanical sources, where the plant was commonly prepared as a tea or infusion. Folk medicine practitioners believed that its mucilaginous properties could soothe mucous membranes and help relieve symptoms associated with colds, such as sore throat and cough.

However, there is a lack of modern scientific studies or clinical trials validating the efficacy of American Liverleaf for preventing or treating colds. No active compounds have been conclusively shown to have antiviral activity or to support immune function relevant to the common cold in humans. As such, the evidence supporting its use for this purpose is almost entirely anecdotal and based on traditional herbal practices, rather than on scientific validation. The tradition persists in some herbal circles, but mainstream medicine does not recognize Hepatica americana as an effective remedy for colds. Therefore, while the use is rooted in tradition, the strength of evidence is very low.
