Clove tea is a popular traditional drink made from aromatic cloves. Learn what clove tea may offer, how to prepare it safely, and why claims about miraculous health benefits should be treated with caution.
Clove tea has become increasingly popular online, especially in posts claiming that drinking it before bedtime can “cleanse the body,” improve digestion, regulate blood sugar, or provide other dramatic health benefits.
But there is an important distinction between traditional use and proven medical effects. Cloves contain eugenol, a plant compound with antioxidant, antimicrobial, and anti-inflammatory properties demonstrated in laboratory research. Human evidence for many of the stronger health claims remains limited.
🌿 Why Do People Drink Clove Tea at Night?
Cloves have a warm, spicy flavor and have traditionally been used in foods and beverages. Some people enjoy a mild clove infusion in the evening because it is caffeine-free and can be a comforting warm drink.
However, there is no strong evidence that drinking clove tea specifically at night provides special health benefits compared with drinking it at another time of day.
1. Cloves Contain Eugenol
Eugenol is one of the major compounds found in cloves. Research has identified antioxidant, antimicrobial, anti-inflammatory, and pain-relieving properties, although laboratory findings don’t necessarily translate into the same effects from drinking a cup of clove tea.
2. It Can Be a Pleasant Caffeine-Free Drink
For people who enjoy the flavor, a mild clove infusion can be an alternative to caffeinated beverages in the evening.
3. It May Feel Soothing After Dinner
Warm beverages can be comforting after a meal. But claims that clove tea “melts belly fat,” “detoxes the liver,” or “kills parasites overnight” are not supported by sufficient human evidence.
☕ How to Make Mild Clove Tea
For a simple homemade drink:
Ingredients:
- 1 cup water
- 2–3 whole cloves
Method:
- Bring the water to a boil.
- Add the cloves.
- Reduce the heat and simmer gently for about 5 minutes.
- Strain and allow the drink to cool to a comfortable temperature.
- Drink it plain.
There’s no need to make the tea extremely concentrated. More cloves don’t necessarily mean more health benefits.
⚠️ Who Should Be Careful?
This is particularly important.
Cloves used in normal culinary quantities are generally well tolerated, but larger medicinal amounts haven’t been well established as safe.
People taking blood-thinning or antiplatelet medicines should speak with a healthcare professional before using concentrated clove preparations because eugenol can affect platelet activity and potentially increase bleeding risk.
Pregnant or breastfeeding women should also avoid medicinal or concentrated clove preparations unless their healthcare professional recommends them; safety information for larger amounts is limited.
And never substitute clove essential oil for clove tea. Concentrated clove oil can be toxic when swallowed, with serious effects possible after large exposures.
The Bottom Line
A mild cup of clove tea can be an enjoyable traditional beverage, but there is no good evidence that a Japanese doctor—or any doctor—can guarantee that drinking it at night will produce extraordinary health effects.
Think of clove tea as a flavorful drink rather than a miracle remedy. If you’re taking medication or considering concentrated herbal preparations, check with your doctor or pharmacist first.
