Background

Liverwort (Hepatica ssp.) is the common name for a genus of herbaceous perennial plants native to central and northern Europe, Asia, and northeastern North America. Liverwort (Hepatica ssp.) should not be confused with Jungermannia ssp., Bazzania ssp., Lepidolaena ssp., Marchantia ssp., Riccardia ssp., Plagiochila ssp., or Frullania ssp., although they are also commonly called liverworts. There is little scientific evidence currently available on the uses of liverwort. One laboratory study indicates that derivatives of liverwort may affect lipid (fat) homeostasis. Liverwort is not listed on the U.S. Food and Drug Administration's Generally Recognized as Safe (GRAS) list.

Evidence

Safety

DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.

Allergies

Avoid in individuals with a known allergy or hypersensitivity to liverwort. Liverwort may cause contact hypersensitivity, such as skin rash.

Side Effects and Warnings

There is very little available information reported on adverse effects. Liverwort is not listed on the U.S. Food and Drug Administration's Generally Recognized as Safe (GRAS) list. Use cautiously in patients sensitive to liverwort. In a case report, liverwort was associated with contact hypersensitivity.

Use cautiously in patients with hypercholesterolemia (high cholesterol) as liverwort may alter lipid levels.

Pregnancy & Breastfeeding

Liverwort is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
