The humble herb cilantro, also known as coriander leaf, is far more than a divisive garnish. While its distinctive flavour is famously polarising, with a genetic variation causing it to taste like soap for an estimated 4 to 14 percent of the U.S. population, its historical and medicinal significance is profound. Emerging research highlights its potential as a powerful functional food with benefits ranging from fighting inflammation to stabilising mood.
A Potent Anti-Inflammatory and Metabolic Ally
Incorporating cilantro into your diet could be a strategic move against chronic inflammation, a root cause of numerous serious conditions. According to the Cleveland Clinic, inflammatory diseases are responsible for more than half of all deaths globally. This herb, rich in vitamin C and antioxidant compounds, may help combat the inflammation linked to autoimmune disorders, neurodegenerative diseases, heart conditions, and certain cancers.
Its role in metabolic health is particularly noteworthy. A 2023 Italian study concluded that coriander extract could be considered a valuable functional food against obesity, metabolic syndrome and diabetes. Cilantro can help fight high blood sugar, a key driver of inflammation. As the University of Utah notes, type 2 diabetes and inflammation are intricately connected, with each condition exacerbating the other.
Neurological and Mental Health Potential
The benefits of cilantro extend powerfully to the brain. Researchers from the University of California, Irvine made a significant discovery regarding one of its components, dodecenal. Dr. Geoff Abbott, a professor at U.C. Irvine, explained that dodecenal binds to potassium channels in the brain to open them, reducing cellular excitability. This mechanism could make cilantro an effective anticonvulsant, potentially leading to new drugs for delaying epileptic seizures.
Intriguingly, the herb may also support mental wellbeing. Preliminary animal studies suggest it could be as effective as Valium at reducing symptoms of anxiety, though more research is needed to confirm these effects in humans. This positions cilantro as a potential dietary tool for both neurological and psychological health.
An Ancient Remedy with Lasting Relevance
Cilantro's use is deeply rooted in history, spanning millennia and cultures. Evidence of its consumption dates back at least 8,000 years, with traces found in the tomb of Egyptian Pharaoh Tutankhamen. The University of Wisconsin notes it was used in Chinese potions where it was believed to confer immortality. While it may not grant eternal life, Dr. Abbott points out its reported anti-bacterial properties add to its portfolio of benefits.
From the kitchens of ancient Egypt to modern clinical research, cilantro continues to reveal its value. For those without the genetic predisposition that makes it taste soapy, it remains a flavourful and potentially powerful addition to a health-conscious diet.
