What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

Overview

Pink Root is the common name for Spigelia marilandica, a flowering plant native to the southeastern and central United States. It is sometimes called Indian pink or worm grass. The plant has bright red, trumpet-shaped flowers with yellow insides and is also grown as a garden ornamental.

The part used in folk medicine is the root and rhizome (the underground stem). Native American and early American settlers used it mainly as a remedy to expel intestinal worms. It is rarely used as a supplement today, and you will not commonly find it on store shelves.

Uses & effectiveness

Historically, Pink Root was used most often as an anthelmintic — a treatment to get rid of intestinal worms such as roundworms. It was also used at times for general digestive complaints.

The evidence behind these uses is very limited and mostly historical. There are no high-quality modern clinical trials showing it works or is safe in humans. Today there are safe, well-studied prescription and over-the-counter deworming medicines, so Pink Root is no longer recommended for this purpose.

How it works

Pink Root contains alkaloids, including a compound traditionally called spigeline, that are thought to affect the nervous system of parasites and possibly the person taking it. This is the proposed reason it was used to paralyze and expel worms.

These ideas come mostly from old observations and traditional use rather than rigorous laboratory or clinical research. The exact active compounds and how they work in the body are not well understood by modern science.

Safety & precautions

Pink Root should be treated with caution. In larger doses it has been reported to cause unpleasant and potentially serious effects on the nervous system and heart. Historically it was sometimes combined with a laxative to help clear it from the body quickly, which suggests people recognized its potential toxicity.

Because there is little reliable safety information, children, older adults, and people with heart, liver, or kidney problems should not use it. Pregnant and breastfeeding people should avoid Pink Root entirely due to the risk of toxicity and the lack of safety data. Always speak with a pharmacist or doctor before considering any product like this.

Side effects

Reported side effects from traditional use include dizziness, blurred or disturbed vision, twitching of the eyelids and face, increased heart rate, and in larger doses more serious nervous system effects such as convulsions.

Because the dose and purity of any product can vary widely, the risk of harmful effects is hard to predict. If you take a Pink Root product and feel unwell, stop using it and seek medical care.

Dosing

There is no established, standardized safe dose of Pink Root for modern use. Historical doses are not considered reliable or safe by today's standards.

Because of its potential toxicity, we do not recommend self-dosing. If you are dealing with a possible parasite or digestive problem, talk with a pharmacist or doctor, who can recommend a safe and proven treatment instead.

Pregnancy & Breastfeeding

Pink Root & Pregnancy

Likely Unsafe

When used orally. For pink root to be effective, it must be used along with a purgative laxative. However, purgative laxative use is contraindicated during pregnancy. For this reason, pink root should not be used in pregnancy.
