As a popular spice, cloves are known for their distinct flavor and numerous health benefits, including antibacterial properties and potential to help regulate blood sugar levels. Like many potent herbs and spices, however, cloves are not suitable for everyone and can have adverse effects when consumed by certain individuals with specific health conditions. Below’s a guide on when you might need to avoid cloves.
Cloves contain eugenol, which is a natural anticoagulant that can reduce blood clotting. This can be beneficial for some, but it’s problematic for people with bleeding disorders such as hemophilia or those who take blood-thinning medications like warfarin. Consuming cloves might increase the risk of bleeding or bruising.
Because of their blood-thinning properties, cloves should be avoided before any surgical procedures to prevent excessive bleeding. It’s generally recommended to stop taking any form of cloves (including oils and supplements) at least two weeks before scheduled surgery.
The safety of consuming cloves during pregnancy and breastfeeding is not well-established. Because of the lack of comprehensive studies and the potential for cloves to stimulate the uterus or cause other side effects, pregnant or nursing mothers should avoid high doses of cloves and clove oil. However, culinary use is generally considered safe.
The use of clove oil in children, especially undiluted, should be avoided because it can be intensely irritating and may cause harm. Cases of liver damage, seizures, and fluid imbalances have been reported from the ingestion of clove oil by children. Please consult a pediatrician before using alternative treatments like clove oil in children’s health care.
Those with allergies to cloves, or more broadly to plants in the Myrtaceae family (which includes eucalyptus, guava, and allspice), should avoid cloves. Reactions can range from skin rashes to breathing difficulties.
Moderate culinary use is generally safe, but consuming cloves in high doses can lead to several issues including irritation of the mouth, throat, and digestive system. High intake of eugenol, the main active component, can also result in liver damage, especially in individuals with existing liver disease.
With their own potent nature, cloves can irritate the GI tract, potentially exacerbating heartburn, acid reflux, or gastric ulcers. If you have a sensitive digestive system, it might be wise to limit or avoid cloves.
It’s important to always consult with a healthcare provider before you start any new dietary supplement, especially if you have existing health conditions or take other medications.
