What is this page for?

First and foremost: how Cat's Foot interacts with medications. The heart of this page is the interaction list — every drug Cat's Foot is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Cat's Foot is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist.

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

Cat's Foot (Antennaria dioica) is a small, low-growing flowering plant in the daisy family (Asteraceae). Its soft, fuzzy flower clusters look a bit like a cat's paw, which is how it got its common name. It is also sometimes called mountain everlasting or pussytoes.

The plant grows in dry, sunny meadows, heaths, and mountain areas across Europe, parts of Asia, and North America. The flowers and the leafy parts above the ground are the parts used in herbal traditions.

In folk medicine, people have brewed Cat's Foot as a tea for coughs, sore throats, and stomach or gallbladder complaints. Today it is a fairly uncommon herb and is not widely studied or sold compared with more popular supplements.

Uses & effectiveness

Cat's Foot has been used in traditional medicine, but there is very little modern clinical research to confirm any of its uses. The evidence behind it is mostly historical and based on tradition rather than well-designed human studies.

People have traditionally used it for:

  • Coughs, sore throat, and chest congestion
  • Stomach and digestive upset
  • Supporting the gallbladder and liver, and bile flow
  • Mild inflammation
  • Diarrhea

To be clear: listing these uses does not mean Cat's Foot is proven to work for them. For most of these purposes, the scientific evidence is limited or absent. Do not rely on Cat's Foot in place of treatments your doctor or pharmacist recommends.

How it works

Cat's Foot contains plant compounds such as flavonoids, tannins, and small amounts of essential oils. In laboratory studies, flavonoids and tannins can have antioxidant and astringent effects, which is one reason the herb has traditionally been used for things like diarrhea and sore throats.

Some of its traditional use for digestive and gallbladder complaints is based on the idea that it may help bile flow, but this has not been proven in people. The astringent tannins may also explain its folk use for coughs and minor irritation.

It is important to know that most of these ideas come from traditional use, test-tube studies, or general knowledge of similar plant compounds — not from solid human research on Cat's Foot itself.

Safety & precautions

There is very little reliable safety information on Cat's Foot. Because of this, it should be used with caution, and it is hard to say what dose or duration is safe.

Cat's Foot belongs to the daisy (Asteraceae) family. People who are allergic to plants like ragweed, marigolds, daisies, or chrysanthemums may be more likely to have an allergic reaction.

Children, older adults, and people with chronic medical conditions (such as liver, gallbladder, or kidney problems) should be especially careful and talk to a healthcare provider first.

Pregnancy and breastfeeding: Because there is no good safety data, it is best to avoid Cat's Foot during pregnancy and while breastfeeding.

Side effects

Because Cat's Foot is not well studied, its full side effect profile is unknown. Based on similar herbs, possible effects could include stomach upset or mild digestive symptoms.

The most important concern is an allergic reaction, especially in people sensitive to other plants in the daisy family. Signs of a serious allergic reaction include rash, itching, swelling of the face or throat, and trouble breathing. If these occur, stop using it and seek medical care right away.

If you notice any unexpected or bothersome symptoms while taking Cat's Foot, stop using it and check with your pharmacist or doctor.

Dosing

There is no established standard dose for Cat's Foot. It has not been studied enough to know what amount is safe or effective.

If you choose to use a product, follow the directions on the label and do not exceed the recommended amount. Because product strength varies, it is wise to start low and watch for any reaction.

Always check with a pharmacist or doctor before starting Cat's Foot, especially if you take other medicines, have a health condition, or are pregnant or breastfeeding.
