Coriander water: Can it help you sleep better?

Coriander, scientific name Coriandrum sativum, is a plant known for its applications in cooking and natural medicine. It belongs to the Apiaceae family and is native to the Middle East and the Mediterranean. Even so, its cultivation has spread throughout the world, so it’s also used in Europe, Africa, and America.

An article published in the journal Molecules details that this species is a source of phytochemicals such as polyphenols, vitamins, and phytosterols. This explains many of the benefits attributed to it.

And while the whole plant is beneficial, its seeds stand out for having a higher concentration of nutrients. In particular, they have an active substance called linalool, which is linked to the ability to modulate the pathogenic pathways of several diseases. But does it work to reduce sleep problems?

In this regard, it’s important to clarify a few things. There’s no scientific evidence that coriander water helps us to sleep better. Many of the effects attributed to its consumption come from anecdotal data.

And although some call it the “magic formula” for sleep, the truth is that it’s not been proven. For now, only some animal studies suggest that coriander has sedative effects and could prolong sleep. Let’s take a look at what the science says in detail.

Research on coriander and its possible effects on sleep quality

One of the reasons why coriander water is believed to help you sleep better is because of its ability to reduce anxiety. In this regard, a study shared in the Journal of Ethnopharmacology determined that the aqueous extract of Coriandrum sativum seeds has anxiolytic and sedative effects.

Researchers even observed that it also has potential as a muscle relaxant, which undoubtedly favors rest. Meanwhile, Natural Product Research reported that coriander has a sleep-prolonging effect without a major neurotoxic effect.

In a more recent review, shared in the Avicenna Journal of Phytomedicine, it was noted that coriander seeds and leaves have antioxidant, sedative-hypnotic, diuretic, and anxiolytic activity.

It was also reported that its main active compound, linalool, has neuropharmacological effects that include anxiolytic, anticonvulsant, sedative, and anti-Alzheimer’s disease potential.

Although these findings are considered promising, they’re still insufficient to prove that coriander water helps you sleep better. This is first of all because they’ve only done in animal models or in the laboratory, and also because extracts have been used and not the beverage prepared in an artisanal way.

Is it safe to consume coriander water?

For most healthy adults, the consumption of coriander water is not a problem. However, it should be a moderate intake, since it can cause stomach discomfort, diarrhea, and photosensitivity when consumed in excess.

However, it shouldn’t be ignored that this drink also has a diuretic effect. Therefore, consuming too much of it before going to sleep can cause the opposite effect. This is because it increases the need to urinate throughout the night, which interrupts rest.

To counteract the above, the best option is to take maximum doses of 200 ml of the drink at least one hour before going to bed.

Due to the lack of studies on its effects and possible interactions, it’s not recommended to consume coriander water in the following cases:

  • Diabetes
  • Pregnancy and lactation
  • Renal or hepatic insufficiency
  • History of coriander allergy
  • People about to undergo surgery
  • People undergoing treatment with anticoagulants, antidiabetics, and antidepressants

In all these cases, it’s best to consult a doctor before consuming coriander water or any other supplement derived from the plant.
