The Recommended Daily Intake
For most healthy adults, a daily intake of one to three whole cloves is considered a safe and beneficial amount. This modest dosage is typically sufficient to provide health-boosting compounds without causing adverse effects. Because of cloves' potent, concentrated flavor and medicinal properties, moderation is the key to incorporating them into your diet effectively.
How Many Whole Cloves?
Several health sources and traditional practices align on a conservative daily dose. Some recommend starting with just a single clove to test your body's reaction and gauge your tolerance for the intense flavor. From there, you can increase to two or three cloves per day. For example, a common practice in Ayurveda is to chew one or two cloves after a meal for digestive aid and fresh breath. Drinking clove tea made with 2-3 cloves is another popular and safe method.
Guidelines by Health Authorities
While there is no universally established recommended dietary allowance (RDA) for cloves as a whole food, some health organizations have provided guidelines for the amount of eugenol, the primary active compound in cloves. The World Health Organization (WHO) suggests an acceptable daily intake of clove-derived compounds at 2.5 mg per kilogram of body weight per day. This illustrates that while a small amount is safe, larger, medicinal doses, especially in supplements or oil, must be treated with caution.
The Benefits of Moderate Clove Intake
Consuming a moderate number of cloves daily can contribute positively to overall health through various mechanisms:
- Powerful Antioxidant Source: Cloves are exceptionally rich in antioxidants, particularly eugenol, which helps combat oxidative stress and cellular damage caused by free radicals. In fact, cloves contain more antioxidants per gram than many berries and fruits.
- Supports Digestive Health: Cloves can help stimulate digestive enzymes, which aids in breaking down food more efficiently and can alleviate common issues like bloating, gas, and indigestion. Its carminative properties also help soothe the stomach.
- Enhances Oral Hygiene: Due to their strong antimicrobial and analgesic properties, cloves have been used for centuries to relieve toothaches and combat oral bacteria. Chewing a clove can act as a natural breath freshener and may help fight gum disease.
- Regulates Blood Sugar: Some studies suggest that compounds in cloves may act like insulin, helping to regulate blood sugar levels by improving insulin sensitivity. This can be particularly beneficial for individuals with prediabetes or type 2 diabetes when part of a balanced diet.
- Anti-inflammatory Effects: The eugenol in cloves possesses potent anti-inflammatory properties, which may help reduce inflammation and alleviate joint pain associated with conditions like arthritis.
- Boosts Immunity: The antibacterial and antiviral attributes of cloves, attributed to eugenol, can help strengthen the immune system and protect against common infections.
The Risks of Excessive Clove Consumption
While moderate use is beneficial, overconsumption of cloves, especially in concentrated forms like supplements or essential oils, can be dangerous. The high concentration of eugenol becomes toxic at elevated doses.
Potential Side Effects
Excessive intake can lead to a range of adverse effects, including:
- Gastrointestinal Irritation: Nausea, vomiting, diarrhea, and heartburn can occur when the digestive system is overwhelmed by the high concentration of eugenol.
- Liver Damage: High doses of eugenol can be cytotoxic to liver cells, with documented cases of liver injury resulting from concentrated clove oil ingestion. This is particularly risky for children or individuals with pre-existing liver conditions.
- Increased Bleeding Risk: Eugenol has blood-thinning properties and can interfere with blood clotting. This is a significant risk for those taking anticoagulant medications like warfarin or for anyone undergoing surgery.
- Hypoglycemia: While moderate intake can help regulate blood sugar, consuming large amounts alongside diabetes medication may cause blood sugar levels to drop too low, resulting in a potentially life-threatening condition called hypoglycemia.
Moderate vs. Excessive Clove Intake
| Feature | Moderate Intake (1-3 whole cloves/day) | Excessive Intake (High concentration/dose) |
|---|---|---|
| Effect | Primarily beneficial with minimal risk | High risk of adverse side effects |
| Eugenol Level | Low, safe concentration | High, potentially toxic concentration |
| Best For | Daily wellness, culinary use | Not recommended for daily use |
| Main Risks | Very low to none for healthy adults | Liver damage, bleeding, hypoglycemia |
| Consumption Method | Whole, ground in food, mild tea | Supplements, pure essential oil |
Safe and Simple Ways to Consume Cloves
Incorporating cloves safely into your diet can be a delicious and health-conscious habit. Avoid the risks of supplements and pure oils by sticking to whole or ground forms in everyday cooking. Healthline provides additional information on the safety of cloves in food amounts.

Conclusion: Moderation Is Your Guide
For a healthy adult, a small number of cloves daily offers a wealth of benefits, from boosting antioxidant intake to improving digestion and oral health. The key is to practice moderation and consume cloves in their whole or ground form rather than concentrated essential oils or supplements. By sticking to a safe dose of one to three whole cloves per day, you can enjoy this potent spice without risking the adverse side effects of overconsumption. Individuals with pre-existing health conditions or those taking certain medications should always consult a healthcare provider before making cloves a regular part of their routine.
