What is cilantro and lemon water?

Cilantro, also known as coriander, is an herb that comes from the leaves of the Coriandrum sativum plant. It has been used for centuries for both culinary and medicinal purposes. Lemon water is simply water that has been infused with fresh lemon juice.

Cilantro and lemon water is generally made by adding a handful of cilantro leaves and the juice from half a lemon to a glass of water. The mixture can be enjoyed either hot or cold. Some people also add other ingredients like mint leaves, grated ginger, honey, or fruit slices to complement the flavors.

Potential health benefits of cilantro

Cilantro contains a unique blend of antioxidants, essential oils, vitamins, and dietary fiber. Here is an overview of some of cilantro’s top nutrients and health benefits:

Rich in antioxidants

Cilantro contains several different antioxidants including quercetin, kaempferol, rhamnetin, and apigenin. These compounds help neutralize harmful free radicals and may help prevent chronic disease.

Anti-inflammatory properties

The antioxidants and active plant compounds in cilantro have anti-inflammatory effects. This may help lower risk of inflammatory conditions like heart disease.

May lower blood sugar

Some research indicates cilantro may help lower blood sugar levels and prevent diabetes complications thanks to compounds like quercetin.

May improve cholesterol

Cilantro contains nutrients that may help improve levels of “bad” LDL cholesterol and raise “good” HDL cholesterol.

Promotes heart health

With antioxidant, anti-inflammatory, and cholesterol-lowering effects, cilantro may help reduce several heart disease risk factors.

Aids digestion

Cilantro’s essential oils stimulate digestive enzymes to help promote efficient digestion and prevent gas and bloating.


Cilantro assists the body’s natural detox process and may help remove heavy metals and other toxic substances.

Provides vitamins and minerals

Cilantro is an excellent source of vitamins A, K, C, and E. It also provides minerals like potassium, calcium, magnesium, iron, and manganese.

Potential health benefits of lemon water

Like cilantro, lemons contain unique plant compounds and essential nutrients. Here are some of the top evidence-based health benefits of lemon water:

Vitamin C

Lemons are among the highest natural sources of vitamin C, an essential antioxidant. Just one lemon can provide over 30% of your daily vitamin C needs.

Aids digestion

Lemon water acts as a mild diuretic to encourage regular bowel movements and may relieve constipation and bloating.

Boosts weight loss

The pectin fiber in lemons can help reduce appetite and promote fullness which supports weight management.

Kidney stone prevention

Citric acid from lemon juice raises urine pH and may prevent kidney stones from forming.

Supports immune function

Vitamin C in lemon boosts the activity of white blood cells which help fight infection and disease.

Protects heart health

Lemons contain antioxidants that lower blood pressure, cholesterol, and heart disease risk.

Freshens breath

Lemon water neutralizes odor-causing bacteria in the mouth and freshens breath.

Balances pH

Although acidic, lemon juice has an alkalizing effect once digested and may help balance body pH.

Promotes hydration

Adding lemon can make plain water more appealing and helps you stay hydrated.

Potential benefits of combining cilantro and lemon water

When cilantro and lemon are infused in water, you get the unique benefits of both ingredients in one beverage. Here are some of the top potential perks:

Enhanced antioxidant activity

Cilantro and lemons contain complementary antioxidants like polyphenols, flavonoids, vitamin C, and vitamin E to reduce oxidative stress.

Improved detoxification

Animal studies reveal cilantro and lemon enhance the activity of detoxification enzymes in the liver to more efficiently remove toxins.

Lower blood sugar

Research shows cilantro and lemon help regulate blood sugar. This may benefit people with diabetes or prediabetes.

Increased weight loss

Cilantro provides fiber and helps reduce appetite and cravings. Lemon water also boosts feelings of fullness to support weight management.

Better heart health

Lemon and cilantro both lower blood pressure, LDL cholesterol, and other cardiovascular disease risk factors.

Improved digestion

Cilantro stimulates digestive enzymes and lemon acts as a mild diuretic. Together, they may relieve bloating, gas, and constipation.

Boosted immunity

Vitamin C in lemon plus antioxidants in cilantro strengthen immune defenses to prevent colds, flu, and infections.

Evidence for the health benefits

Most of the purported benefits of cilantro and lemon water come from anecdotal reports. However, some scientific studies provide evidence to support these health claims:

Lower cholesterol

In a 6-week study in people with elevated lipids, taking cilantro leaf extract significantly decreased total cholesterol, LDL cholesterol, and triglyceride levels.

Improved antioxidant status

Several studies reveal cilantro and lemon improve antioxidant levels in the body and help inhibit oxidative stress.

Lower blood sugar

Human and animal studies indicate extracts from cilantro and lemon positively impact blood sugar control.

Increased detoxification

Animal research found cilantro leaves increase levels of detoxification enzymes in the liver, kidneys, intestine, lungs, and skin.

Study Type Key Finding
Human clinical trial Cilantro lowered LDL cholesterol by 17% over 6 weeks
Animal study Lemon polyphenols decreased blood glucose by 27%
Test tube study Cilantro extract doubled antioxidant levels in cells

While research is still emerging, the current evidence supports many of the purported benefits of sipping cilantro and lemon infused water.

Potential side effects and precautions

For most people, enjoying cilantro and lemon water is safe with very few side effects. However, here are some things to keep in mind:

Blood thinning medications
