Greater celandine (Chelidonium majus) is a plant long used in herbal medicine and in traditional Chinese medicine. Available in supplement form, greater celandine is often said to fight cancer. Although research suggests that greater celandine may offer certain health benefits, there's also some evidence that it might be toxic to the liver.
Uses for Greater Celandine
Greater celandine is touted as a natural remedy for a number of health conditions, including:
- high blood pressure
- irritable bowel syndrome
- menstrual problems
Benefits of Greater Celandine
To date, research on the health effects of greater celandine is fairly limited. However, there's some evidence that greater celandine may offer certain benefits. Here's a look at some key study findings:
A greater celandine extract shows potential as an anti-cancer drug, according to a research review published in BMC Cancer in 2005. For the review, investigators analyzed seven clinical trials on the use of a proprietary greater celandine extract (called Ukrain) in treatment of cancer. Although the review's authors found that the extract had beneficial effects on several types of cancer, they caution that most of the trials were of poor quality and state that "independent rigorous studies are urgently needed" before greater celandine can be recommended in treatment of cancer.
In laboratory tests on human cancer cells, scientists have found that greater celandine may fight cancer by inducing apoptosis (a type of programmed cell death involved in stopping the spread of cancer cells).
Preliminary research indicates that greater celandine may help treat atopic dermatitis (a form of eczema). In a 2011 study published in the Journal of Ethnopharmacology, for instance, researchers tested the effects of greater celandine on a group of mice with atopic dermatitis. Results revealed that greater celandine significantly reduced the severity of several eczema symptoms, including itching and inflammation. However, it's unknown whether greater celandine might have the same effect on eczema in humans.
Is Greater Celandine Safe?
There's some concern that greater celandine may harm liver health. In a report published in the Journal of Ethnopharmacology in 2009, for instance, scientists warn that several cases of acute hepatitis have been linked to greater celandine consumption in previously published studies.
Given the potential for liver damage, it's critical to consult your physician prior to using greater celandine (especially if you have a history of liver problems).
Side Effects of Greater Celandine
Greater celandine may trigger a number of side effects, including nausea, dizziness, fatigue, and fever.
Where to Find Greater Celandine
Widely available for purchase online, greater celandine is sold in many natural-food stores and in stores specializing in dietary supplements.
Should You Use Greater Celandine for Health Purposes?
Due to a lack of supporting research, greater celandine cannot currently be recommended for treatment or prevention of any health problem. If you're considering the use of greater celandine supplements, consult your doctor before starting your supplement regimen.
It's important to note that self-treating a chronic condition with greater celandine and avoiding or delaying standard care may have serious health consequences.
