Track Fringe Tree with reminders and record whether it helped, in the app.
Fringe Tree is the root bark of a small North American tree, Chionanthus virginicus. American folk and Eclectic healers used it for liver and gallbladder complaints. Human evidence for any of those uses is essentially absent.
The tree grows wild in the southeastern United States. Gardeners also plant it for its white, fringe-like flowers. Other names include Old Man's Beard, Snowdrop Tree and Poison Ash.
Long traditional use is not proof that a remedy works. It is also not proof that it is safe. Fringe Tree has both gaps, so treat it as untested rather than proven.
The short answer: no one has shown how Fringe Tree works in people.
Eclectic doctors believed the root bark made the liver release more bile. Bile is the fluid that helps you digest fat. That idea came from bedside watching, not from lab or trial work.
Modern laboratory work on the plant is thin. A few reports have looked at its saponins and related compounds in test tubes. None of that tells you what happens inside a person who takes it.
Claims that it "cleanses" or "detoxes" the liver have no support in human studies. Your liver and kidneys already clear waste on their own.
Fringe Tree is sold mainly as a liquid extract of the root bark.
Forms you may see: - tincture, the root bark soaked in alcohol - glycerite, an alcohol-free liquid extract - dried root bark, loose or in capsules - homeopathic drops, which are very dilute
Dried bark was the old Eclectic form. Tinctures are the most common form today.
Quality is hard to judge from the outside. Buy only from sellers who name the species and the plant part. The fruit is not a food and is not sold as one.
Fringe Tree was a well-known liver remedy in 19th-century American practice.
Eclectic physicians were American doctors who leaned on plant medicines. Their dispensatories listed Fringe Tree for jaundice and gallstone pain from about 1850 onward. Appalachian folk healers used the bark in much the same way.
Early homeopathy also gave it a place for liver complaints.
Use faded in the 20th century as the Eclectic schools closed. It survives today in some herbalist practice and in homeopathic product lines.
Stop taking it and see a doctor if you get: - yellow skin or eyes - dark urine or pale stools - pain in the upper right belly - vomiting that will not settle - fever with belly pain - a rash, itching, or swelling of the face or lips
Go to an emergency department for severe belly pain with fever, or for pain that spreads to your back or shoulder. Those can mean a blocked duct or an infected gallbladder.
Tell any doctor or pharmacist that you have been taking Fringe Tree. It helps them read your liver blood tests.
In the United States, Fringe Tree is sold as a dietary supplement. It is not approved as a drug, so sellers may not claim it treats disease.
In the UK and the EU it is an unlicensed herbal product. It has no traditional herbal registration, and you may not find it on shelves there.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Fringe Tree is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
