Here’s a full, evidence‑based article about what doctors and health experts say about using cloves — including benefits and possible risks (what it “causes” when you use it). Most of this is based on medical sources and expert summaries rather than unverified claims.
What Doctors Reveal About Using Cloves — Benefits, Risks, and What It Really Does
Cloves (Syzygium aromaticum) are aromatic spice buds used worldwide in cooking, traditional medicine, and herbal remedies. They contain several active compounds, especially eugenol, which is responsible for much of their biological activity. (WebMD)
🌿 Health Benefits of Cloves
✅ 1. Rich in Antioxidants
Cloves are loaded with antioxidants, which help fight oxidative stress — a contributor to chronic diseases like heart disease and cancer. (Healthline)
✅ 2. Anti‑Inflammatory Effects
The eugenol in cloves has anti‑inflammatory actions. This may support joint comfort and general inflammation reduction. (WebMD)
✅ 3. Potential Antimicrobial Properties
Cloves and clove oil can inhibit growth of certain bacteria and fungi; this is why cloves have traditionally been used to help with oral health and toothache. (Healthline)
✅ 4. May Help with Blood Sugar Regulation
Some small studies show clove extract may help lower blood glucose levels, though most research is early or done with concentrated extracts. (Healthline)
🦷 5. Traditional Uses for Oral Care
Cloves have been used for centuries to soothe tooth pain and fight mouth bacteria, and some studies support these effects when used carefully in dental preparations. (The Times of India)
⚠️ What Cloves Can Cause (Side Effects & Risks)
Although cloves are safe in culinary amounts, concentrated or excessive use — especially of clove oil — can have significant health effects:
🔻 1. Risk of Hypoglycemia
Cloves can lower blood sugar. For people with diabetes or on insulin or other blood sugar‑lowering drugs, this may lead to dangerously low blood sugar levels. (WebMD)
🔻 2. Drug Interactions
Eugenol (from cloves) may interact with blood thinners like warfarin or aspirin and increase bleeding risk, especially around surgery. (WebMD)
🔻 3. Liver Toxicity (Especially Clove Oil)
High doses of clove oil have been linked to liver damage, which in rare cases may be severe — particularly in children or with repeated high intake. (WebMD)
🔻 4. Allergic or Irritation Reactions
Direct application of clove oil on gums or skin may cause irritation, burning, or allergic reactions. (WebMD)
🔻 5. Gastrointestinal Upset
In some people, ingesting cloves or clove water can cause stomach discomfort, nausea, or other digestive issues. (Reddit)
📌 Important Safety Notes Doctors Emphasize
- Clove spice in food — safe in normal amounts.
- Clove oil or extracts — far more potent and should be used cautiously or avoided without medical guidance. (WebMD)
- Children, pregnant/nursing women, and people with liver issues or on medications should avoid medicinal doses of clove products unless supervised by a healthcare provider. (WebMD)
🧪 What About “Clove Water” or Home Remedies?
Some people boil cloves and drink the water thinking it can lower blood sugar or reduce inflammation. While cloves do contain beneficial compounds, scientific evidence shows little clinical benefit from clove‑infused water alone, and effects seen in studies typically use concentrated extracts rather than simple clove water.

🧠 Bottom Line: What Doctors Really Say
👉 Using cloves as a spice in your food is generally safe and can offer mild antioxidant and anti‑inflammatory benefits. (Healthline)
👉 Medical benefits beyond flavor or nutrition are not strongly proven, and many health claims online are exaggerated or based on traditional use rather than solid clinical evidence.
👉 High‑dose clove oil or supplements can cause serious side effects (low blood sugar, bleeding issues, liver problems), so avoid large amounts and talk with a doctor before trying them for health reasons. (WebMD)
If you’d like, I can also summarize natural ways to use cloves safely (like in cooking, teas, or for oral care) that avoid these risks — just let me know!
