While further research is necessary, including this perfumed herb into one’s diet or utilizing its smell may offer a natural approach to supporting mental wellness.
What is Cilantro?
Cilantro (Coriandrum sativum) is an aromatic herb belonging to the Apiaceae family, widely cultivated as an annual plant that thrives in cooler weather. The cilantro plant features thin, delicate green stems adorned with bright green, flat, fern like leaves showing a distinctive, strong aroma and flavor. While some perceive its flavor as uniquely citrusy and refreshing, others detect a soapy or unpleasant taste due to genetic variations in scent receptors. Cilantro’s fresh leaves are commonly used as a garnish, seasoning, or ingredient in various dishes like salsas, chutneys, curries, and soups, particularly in Mexican, Indian, and Southeast Asian cuisines. Its seeds, known as coriander seeds, have a different flavor and are used as a spice. Nutritionally, cilantro is a good source of vitamins K, A, and C, as well as minerals like potassium, calcium, and iron, and contains antioxidants and phytochemicals with potential health benefits. Some individuals experience a strong dislike to cilantro’s taste, a phenomenon known as cilantro aversion or cilantro-phobia, due to genetic differences in olfactory receptors.
Various Research shows that cilantro may offer potential benefits for mental health. Here are some of the purported mental health benefits of cilantro:
1. Anti-anxiety properties:
Cilantro may offer potential benefits for reducing anxiety due to its natural compounds and properties, such as containing various anxiolytic compounds like linalool, geranyl acetate, and carvone that interact with the brain’s GABA receptors, playing a crucial role in regulating anxiety and promoting relaxation. Additionally, some components in cilantro, like linalool and geranyl acetate, possess sedative and calming properties that may help reduce feelings of anxiety and promote a sense of relaxation by modulating the activity of the central nervous system.
Cilantro is also rich in antioxidants, including flavonoids and polyphenols, which can combat oxidative stress in the brain linked to anxiety and other mental health conditions, potentially alleviating anxiety symptoms by reducing inflammation and protecting brain cells. Furthermore, the distinctive smell of cilantro, often described as refreshing and calming, may have a soothing effect on the nervous system and potentially reduce anxiety levels when inhaled through aromatherapy or by crushing the leaves. While the evidence for cilantro’s anxiolytic effects is promising, more research is needed to fully understand its mechanisms of action and efficacy, and it should not be considered a substitute for professional medical treatment for anxiety disorders, as persistent or severe anxiety warrants consultation with a healthcare professional for appropriate guidance and treatment.
The study published in the FASEB Journal showed that Cilantro leaf exhibits anticonvulsant properties due to its potent potassium channel activation, providing a molecular basis for its therapeutic actions.
2. Antidepressant effects
Cilantro (Coriandrum sativum) contains several compounds that contribute to its potential antidepressant effects. According to research publish in Journal of Essential Oil Research Linalool and geranyl acetate, terpene compounds found in cilantro’s essential oil, possess anxiolytic (anti-anxiety) and sedative properties by interacting with the brain’s GABA (gamma-aminobutyric acid) receptors, indirectly contributing to their antidepressant potential. Additionally, another research shows cilantro is rich in flavonoids like quercetin and kaempferol, which exhibit neuroprotective and anti-inflammatory properties, as well as the ability to modulate neurotransmitter levels, including serotonin and dopamine, crucial in regulating mood. Polyphenolic compounds such as caffeic acid and ferulic acid present in cilantro have antioxidant and anti-inflammatory effects, potentially alleviating symptoms of depression by reducing oxidative stress and inflammation in the brain.
3. Stress relief:
Unique blend of bioactive compounds in Cilantro, particularly linalool, coupled with antioxidant, anxiolytic, and neurotransmitter-modulating effects, contributes to its stress-relieving potential. Numerous studies have delved into the intricate mechanisms underlying cilantro’s ability to promote relaxation and alleviate the manifestations of stress.
According to research publish on Food Research International Linalool, a major compound in Cilantro seeds, is noted for its ability to modulate key disease pathways and possesses potent antioxidant properties, which may contribute to its stress-relieving effects. Another research published in Journal of Functional Foods reveals Aqueous extracts of C. sativum seeds have been shown to exhibit anxiolytic activity, improve exploratory behavior, and restore neurotransmitter levels in animal models, suggesting a role in stress management. According to research published in Tropical Journal of Pharmaceutical Research The anti-stress effects of C. sativum are also supported by its ability to reduce urinary levels of stress markers and increase ascorbic acid excretion in rats, alongside its anti-amnestic and antioxidant activities.
These findings support the traditional use of cilantro as a functional food for promoting well-being and managing stress-related disorders.
4. Neuroprotective effects
coriander, contains several neuroprotective compounds that function to protect the brain through various mechanisms. According to research the hydroalcoholic seed extract of Coriandrum sativum has been shown to alleviate oxidative stress in rat brains caused by lead exposure. This extract significantly reduced reactive oxygen species (ROS), lipid peroxidation products (LPP), and total protein carbonyl content (TPCC) levels, which are indicators of oxidative damage. The hydro-alcoholic extract of Coriandrum sativum seeds was found to modulate oxidative/nitrosative stress and reduce the expression of inflammatory cytokine TNF-α in diabetic neuropathic rats. This suggests a role in improving neuronal function and attenuating neuropathic pain. Coriandrum sativum contains various compounds that exhibit neuroprotective effects through antioxidant activity, neurotransmitter regulation, anti-inflammatory properties, inhibition of oxidative/nitrosative stress and inflammatory cytokines, suppression of glial cell proliferation and ERK activation, memory improvement, prevention of neuronal damage, and modulation of brain oxidative stress and neuronal electrophysiology.
5. Improved sleep
Cilantro (Coriandrum sativum) has a calming effect due to its essential oil and specific compounds like linalool. Studies on animals have shown that cilantro can make them less active and help them sleep longer. The way cilantro’s compounds interact with receptors in the brain suggests that cilantro may be useful for improving sleep and treating mental health issues. According to research Coriander essential oil, specifically linalool, has a sedative effect in newborn chicks similar to diazepam when given directly into the brain through a specific method. This suggests that coriander essential oil, particularly its component linalool, may have potential as a natural sedative. Compounds found in Coriandrum sativum, such as terpenes and flavonoids, have shown in vitro and in vivo activities against central nervous system disorders and interact with key neurotransmitter receptors, suggesting potential as anxiolytics, antidepressants, antiepileptics, or sleep enhancers.
