  • Although there is currently no cure for IBD, which includes Crohn’s disease and ulcerative colitis, medications and lifestyle changes can help alleviate symptoms.
  • Research is currently examining how certain supplements and spices may help with IBD.
  • Researchers from Howard University recently presented a study reporting that saffron may help reduce inflammation and improve clinical manifestations in people with ulcerative colitis.

About 7 million people around the world live with inflammatory bowel disease (IBD).

IBD refers to two chronic inflammatory conditions that affect the digestive system — Crohn’s disease and ulcerative colitis.

There is currently no cure for IBD. Medications are available to help reduce inflammation and alleviate symptoms. Additionally, people with IBD often change some lifestyle factors — especially diet — to better manage their condition.

People with IBD may also be lacking in certain vitamins and minerals and their doctors may prescribe supplementation.

There is also research currently looking at whether some other supplements and spices — including omega-3 fatty acids, turmeric, vitamin D, and probiotics — may also help with IBD.

Now, researchers from Howard University in Washington, DC, are adding to this list with a recent presentation at the annual Crohn’s & Colitis Congress reporting that the herb saffron may help reduce inflammation and improve clinical manifestations in people with ulcerative colitis.

Saffron is a spice derived from the Crocus sativus flower. The stigmas of the flower — which look like threads — are harvested and dried.

The majority of saffron is grown in Iran, and it can also be found in India, Spain, and Afghanistan.

Saffron is known as the Health">most expensive spice in the world, giving it the nickname “red gold.” That is because cultivating and harvesting saffron is extremely labor intensive.

Since as far back as 1,627 Before the Common Era (BCE), saffron has been used not only in food but for medicinal purposes.

Previous research shows saffron has high levels of antioxidants and anti-inflammatory properties.

Scientists are currently looking at saffron for the treatment of a variety of health conditions, including:

  • depression
  • Alzheimer’s disease
  • cancer
  • heart disease
  • obesity
  • reducing PMS symptoms
  • sleep issues
  • age-related macular degeneration (AMD).

For this study, researchers recruited 30 participants with ulcerative colitis at Yazd University in Iran.

Participants either received low or high doses of saffron or a placebo two times a day for 8 weeks.

At the start of the study, scientists recorded participants’ scores on the Simple Clinical Colitis Activity Index (SCCAI), Partial Mayo Score, and Hamilton Depression Anxiety Score (HDRS). They also collected information on inflammatory markers for IBD, including fecal calprotectin and C-reactive protein (CRP).

After eight weeks, the researchers found that people who took high doses of saffron had significant improvement in their HDRS and Partial Mayo scores, as well as their fecal calprotectin and CRP inflammatory biomarkers.

The low-dose saffron group also showed improvement in their HDRS scores.

To help further validate these results, researchers recruited three people with ulcerative colitis at Howard University who received 50 milligrams (mg) of saffron twice a day for eight weeks. These participants then underwent a washout period, which allows the study participants’ bodies to “reset.” They then underwent a second saffron cycle.

Scientists reported that during the washout period, participants’ fecal calprotectin increased. After the second saffron cycle, the fecal calprotectin once again was reduced, which the researchers state further validates a causal relationship between saffron ingestions and gastrointestinal improvements in IBD.

Taking saffron also led to a decrease in Gammaproteobacteria — a bacterium that occurs at a higher abundance in IBD — and an enrichment in Ruminococcaceae, a bacterium that is typically reduced in people with IBD.

According to Monique Richard, a registered dietitian nutritionist and owner of Nutrition-In-Sight in Johnson City, TN, who was not involved in this study, crocins are an active component of saffron that may allow it to help with inflammation and other IBD-related symptoms.

“The crocins are carotenoids, responsible for saffron’s yellow-red color, just like the carotenoids responsible for the yellow, orange, and red in carrots, beets, [and] peppers. The compound crocin goes through a chemical reaction and transformation to form what is called, Health">crocetin, most responsible for the pharmacological activities and medicinal properties of saffron.”

“Some of these values may include being protective — cardioprotective, hepatoprotective, neuroprotective — [as well as] the ‘anti’s — antidepressant, antiviral, anticancer, antidiabetic [effects] — and [may] even possibly [be] linked to enhancing memory,” she explained.

Richard said crocetin seems to act a little like an adaptogen in that it can be used in different mechanisms.

“For example, inhibiting inflammation, stimulating cell death in cancer cells, or protecting cells from reactive oxygen species (ROS) damage — these attributes would be directly related to how it may be beneficial to IBD and similar gastrointestinal conditions and disease states,” she added.

MNT also spoke with Dr. Rudolph Bedford, a board-certified gastroenterologist at Providence Saint John’s Health Center in Santa Monica, CA, about this study.

Dr. Bedford said he found the study to be interesting and innovative as doctors are always looking for supplements or other benign products that may help and treat people with ulcerative colitis.

“If you can find something that has minimal or no side effects whatsoever, then that obviously would be the optimal thing to do,” he continued. “And things like saffron [have] antioxidative effects, therefore mitigating any inflammatory response from the disease itself.”

Moving forward, Dr. Bedford said he would like to see this research conducted in a study with a larger participant population that is further categorized with mild, moderate, and severe ulcerative colitis.

He also said there is no doubt that researchers should also examine the use of saffron as a potential treatment for Crohn’s disease.

“I can just imagine saffron and products like it being used in this disease,” Dr. Bedford added. “As a matter of fact, after reading this study, it may be something I will suggest to some of my patients.”

Should I use saffron if I have IBD?

“Treating IBD and its symptoms typically requires a multi-faceted approach addressing diet, gut microflora, targeted supplementation, [and] hydration, in addition to possible digestive aids, stress management, and conventional medicine. Saffron may be appropriate for some individuals but should be assessed [on] a per-case basis and may not be appropriate for everyone.”
