Parts Used & Where Grown

Lobelia grows throughout North America. The leaves are primarily used in herbal medicine.

  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditional Use (May Not Be Supported by Scientific Studies)

Eclectic physicians, early North American doctors who used herbs as their primary medicine, considered lobelia to be one of the most important medicinal plants.1 It was used by Eclectics to treat coughs and spasms in the lungs from varying causes, as well as spasms elsewhere in the body, including the intestines and ureters (passages from the kidney to the bladder).2 Lobelia was also considered a useful pain reliever and in higher amounts was used to induce vomiting in people who had been poisoned.
