Cilantro remains one of the most divisive herbs in the kitchen — people either love its freshness or can’t stand its taste.
For some, it adds a refreshing burst of flavor to salads, curries, and guacamole. For others, it’s simply unbearable and tastes like soap.
Scientists say that difference comes down to genetics. A specific gene variation changes how some people perceive cilantro’s aroma and taste.
Why Cilantro Tastes Like Soap for Some People
Experts estimate that between 4% and 14% of Americans have this genetic trait. Those who carry it find cilantro soapy or metallic, while others experience it as bright and citrusy.
“It is estimated that four to 14 percent of the U.S. population has this genetic variation, making cilantro taste like soap,” said Brooke Baevsky, a private chef and CEO of In the Kitchen with Chef Bae.
For everyone else, cilantro is a fragrant herb that adds freshness and depth to many global cuisines.
Packed with Nutrients and Anti-Inflammatory Properties
Beyond taste, cilantro is rich in vitamin C and antioxidants that help combat inflammation — a major factor in autoimmune, heart, and neurodegenerative diseases.
According to the Cleveland Clinic, inflammatory conditions account for more than half of all deaths globally. Cilantro’s compounds can help lower inflammation linked to such illnesses.
A 2023 Italian study also found that coriander extract — derived from the same plant — could help fight obesity, diabetes, and metabolic syndrome, thanks to its bioactive properties.
Helps Control Blood Sugar and Protects the Brain
Cilantro may also help regulate blood sugar levels. When glucose levels remain high, the body triggers an immune response that can damage tissues and nerves.
The University of Utah explains that “Type 2 diabetes and inflammation are intricately connected, with each condition exacerbating the other.”
Research at U.C. Irvine identified a compound in cilantro called dodecenal, which helps calm overactive cells in the brain, potentially preventing epileptic seizures.
Supports Mental and Emotional Wellbeing
Early studies on animals suggest cilantro might reduce anxiety levels as effectively as Valium, though more human research is needed.
The herb has been used for over 8,000 years and was even discovered in the tomb of Egyptian King Tutankhamen. Ancient Chinese texts also praised it for promoting longevity.
While it may not make anyone immortal, researchers say cilantro possesses natural anti-bacterial properties that support gut and immune health.
Cilantro’s natural compounds, including polyphenols, may help reduce inflammation linked to chronic diseases such as obesity, metabolic syndrome, and diabetes. While studies cited by Health.com and the National Institutes of Health highlight its potential, experts emphasize that more research is needed to fully understand how cilantro contributes to long-term health.
As Dr. Geoff Abbott of U.C. Irvine put it, “The best part is — it tastes good.”
