Coriander water, or dhania water, is a traditional herbal beverage prepared by either soaking or boiling coriander seeds in water. Coriandrum sativum, commonly known as coriander, has been traditionally used in Indian cooking and alternative medicine.
Plant chemicals contained in coriander seeds include polyphenols and essential oils. Even though coriander is a highly nutritious food, it should be mentioned that coriander water is an herbal infusion. There are a number of health benefits connected with the consumption of this beverage; however, most of them have been proven in experiments only on animals or in a lab.
1. Can help with digestion

One of the most frequent uses of coriander water is related to digestion problems. This plant has been used since ancient times to deal with bloating, flatulence, and other problems of the stomach.
Although there is information that some natural components affect digestive processes, the evidence showing that coriander water helps to eliminate these problems among people is insufficient.
It is just an additional drink, while persistent stomach pain requires medical attention.
2. Provides Antioxidant Compounds

The composition of coriander includes various substances with the property of being antioxidants, for example, phenolic compounds and flavonoids.
Antioxidants provide protection of cells from oxidation processes. Certain components can dissolve in water during soaking and boiling, yet the quantity remains to be seen.
Coriander water is a component of diversified nutrition; however, it cannot be considered a means of preventing chronic diseases.
3. May Influence Blood Sugar
The ability of coriander to affect blood glucose metabolism is rather interesting.
Some results of laboratory tests have been obtained, but there is still a lack of evidence in humans. Therefore, coriander water cannot be used instead of medication, glucose testing or recommended dietary restrictions.
It is necessary to exercise caution in using coriander water in conjunction with medicines that decrease glucose levels in the blood.
4. Promotes Hydration

Coriander water is mostly water, which means its consumption is a part of the daily fluid intake.
The taste of coriander water can encourage people to drink more water, particularly during the summer period. It does not help hydration any better than water does, though.
Sugar should not be added in large quantities when making a low-calorie drink.
5. May Support Heart-Friendly Eating
However, coriander seeds include phytonutrients which have been studied regarding their potential influence on blood lipids and cardiovascular health.
The bulk of scientific evidence is generated in animal or laboratory studies; hence, the suggestion that coriander water helps lower cholesterol levels or prevents heart diseases is rather exaggerated.
A heart-healthy way of living requires, first of all, a well-balanced diet, exercise, a healthy body weight and appropriate medical treatment.
6. Demonstrates Potentially Anti-Inflammatory Activity

Several chemicals contained in coriander exhibit anti-inflammatory effects during experiments.
Although the issue is interesting, no study has proved that drinking coriander water could cure rheumatoid arthritis, autoimmune disorders or any inflammation.
Coriander water is better regarded as a nutritious drink than an anti-inflammatory medication.
7. Provides Skin Nutritious Benefits in a Secondary Way

Coriander includes antioxidants and other phytonutrients, making it nutritious.
Proper hydration also promotes normal functioning of the skin. Nevertheless, there is insufficient scientific evidence that coriander water can help remove acne, pigmentation and make your skin glow.
Recurrent skin issues should be diagnosed by a doctor.
8. Can Be a Low-Calorie Beverage
Plain coriander water does not contain many calories, and therefore serves as a healthy substitute for drinks that are loaded with calories and sweetened beverages such as tea.
It may have an indirect effect on weight reduction by substituting high-calorie drinks.
Nevertheless, coriander water alone does not contribute to burning fat and losing weight.
9. Coriander Water for Thyroid Health?
Coriander water is used as a remedy for thyroid gland disorders on the Internet.
However, there are no studies that could provide reliable evidence of its ability to cure hypothyroidism and hyperthyroidism or replace thyroid drugs.
It is recommended that people with any thyroid disease take their medications.
10. Does Coriander Water Detox the Body?

“Detox” is often used in reference to herbal beverages, whereas the body has complex organs (liver and kidneys) designed to eliminate waste and toxins.
Drinking coriander water provides water but does not detoxify or remove toxins and metals from the body.
The body requires proper hydration, food, and sleep rather than special drinks to keep the organs functioning normally.
How to Prepare Coriander Water

Another simple way of making coriander water is by soaking one teaspoon of coriander seeds in a glass of water overnight. Strain before consumption.
Another way to make coriander water is by boiling coriander seeds in water until the solution cools down and straining it.
There is no proven need to take it only when fasting. You can choose any suitable timing for your needs.
Possible Side Effects
The use of coriander in food is considered quite safe for most people. The excessive consumption of concentrated coriander water or other preparations may cause digestive problems and allergic reactions in sensitive individuals.
Since coriander has the potential to affect blood sugar levels and blood pressure, you need to exercise caution while taking concentrated coriander water with medicines intended to treat these health issues.
Pregnant and breastfeeding women need to consult their doctor prior to consuming coriander water and any other coriander-based medicine.
Personal Preference

For me, the biggest advantage of coriander water is that it is very easy to prepare.
I prefer my coriander-seed water light and unsweetened. I consider it to be an additional ingredient in my healthy lifestyle rather than a tool for detoxification and treatment.
Conclusion
Coriander water is an easy traditional drink that may contain antioxidants, help with hydration and possibly improve your digestive process. Studies conducted on the effects of coriander on blood sugar levels, inflammation and heart health show promise, but there is not enough evidence to consider coriander water a medicine.
The best thing you can do for your health is drink coriander water occasionally as part of your balanced diet and avoid making exaggerated statements about its health benefits.
