Cloves, ginger, oregano and turmeric contain concentrated plant compounds with antioxidant and anti-inflammatory properties, though dietitians say culinary use is preferable to high-dose supplements and laboratory antioxidant scores do not necessarily predict benefits in the human body.

A pinch of cloves, fresh ginger, oregano or turmeric can do more than change the flavor of a meal, with registered dietitians pointing to all four spices as concentrated dietary sources of antioxidant compounds.
Cinnamon is often used as a benchmark when antioxidant-rich spices are discussed. A pooled analysis of 21 meta-analyses containing 139 placebo-controlled comparisons found cinnamon supplementation was associated with reductions in HbA1c, total cholesterol, LDL cholesterol and blood pressure, according to research published in Frontiers in Nutrition.
Registered dietitians Seema Shah, Amanda Crowe and Jennifer Bianchini said several other familiar kitchen spices also contain substantial concentrations of potentially beneficial plant compounds, particularly cloves, ginger, oregano and turmeric.
Antioxidants help neutralize free radicals, unstable molecules capable of damaging cells when produced in excess. A NaturalNews.com report described antioxidants as compounds that can counter free radicals associated with weakened immune function and disease.
Herbs and spices can contain unusually high concentrations of these compounds. A 2015 report by Dr. Mercola stated that, gram for gram on a fresh-weight basis, herbs can rank above fruits and vegetables in laboratory measurements of antioxidant activity.
The U.S. Department of Agriculture’s former Oxygen Radical Absorbance Capacity database, commonly known as ORAC, measured the antioxidant potential of foods under laboratory conditions and listed foods including unprocessed cocoa beans, cinnamon and pecans among high-scoring selections.
Shah cautioned that ORAC values measure what occurs in a laboratory rather than what necessarily happens after a food is eaten. Digestion, absorption, metabolism and interactions among compounds can substantially influence their effects inside the human body.
That distinction makes the practical question less about finding the spice with the highest laboratory number and more about incorporating a variety of plant foods into everyday meals.
Common culinary herbs and spices contain numerous bioactive compounds studied for antibacterial, antifungal, antiviral, antioxidant and anti-inflammatory properties.
Cloves
Among common spices, cloves stand out for their particularly concentrated antioxidant content.
Shah said ground cloves have a higher ORAC value than cinnamon. Their naturally occurring antioxidant compounds include eugenol, flavonoids and gallic acid.
A 2025 study suggested antioxidants derived from clove pods may exert effects at relatively low concentrations, while eugenol has also been investigated for antibacterial properties.
Earlier animal research examined cloves in connection with oxidative stress. A 2005 study in the Journal of Applied Toxicology investigated the antioxidant effects of black cumin and cloves in rats experiencing aflatoxicosis.
Crowe said only a small amount is needed in ordinary foods. A pinch of ground cloves can be added to oatmeal, yogurt or baked dishes, while whole cloves can be incorporated into simmered beverages.
Research and nutritional reviews have also examined cloves alongside cinnamon, oregano, thyme and sage as practical dietary sources of antioxidants. Some reports suggest compounds from those spices may be more readily absorbed than isolated curcumin from turmeric.
That does not mean more is necessarily better.
Shah cautioned that consuming high amounts of ground cloves — more than approximately one-fourth teaspoon — may pose liver risks.
The concentrated nature of spices is one reason dietitians generally distinguish routine culinary use from supplements and essential oils, which can deliver much higher doses.
Culinary herbs and spices contribute few calories while supplying biologically active compounds that have been studied for potential hypoglycemic, lipid-lowering and anti-inflammatory activity.
Ginger
Ginger provides a different mixture of plant chemicals depending partly on whether it is consumed fresh or dried.
Crowe said both forms can be useful, although fresh ginger contains additional aromatic compounds.
One of ginger’s best-known constituents is gingerol. During drying and processing, gingerols can convert into compounds known as shogaols. Both have been investigated for anti-inflammatory and anti-tumor activity.
A 2020 research review reported that ginger can influence inflammatory signaling by increasing anti-inflammatory cytokines while decreasing pro-inflammatory cytokines.
More recent research published in Nutrients examined common culinary herbs and spices, including ginger, and reported effects associated with beneficial gut bacteria.
Ginger’s use predates modern nutritional science by thousands of years. Historical accounts describe spices being used medicinally in ancient Egypt and Asia and as food preservatives in Greece and Rome.
Integrative physicians have sometimes referred to common herbs and spices as a “Kitchen Pharmacy,” pointing to ingredients such as ginger, turmeric, cinnamon and black pepper as dietary sources of antioxidants and anti-inflammatory compounds.
Bianchini said ginger is generally safe at quantities normally used in recipes. Concentrated supplements, however, can cause digestive symptoms and may interact with medications.
The broader nutritional interest in antioxidants extends to cardiovascular health. Sarah Brewer’s writing on nutrition has discussed research proposing that inadequate dietary antioxidant intake may contribute to coronary heart disease by allowing greater oxidation of circulating fats.
That hypothesis does not establish ginger or another individual spice as a treatment for heart disease, but it illustrates why researchers continue examining antioxidant-rich dietary patterns.
Oregano
Oregano is another kitchen staple with a high laboratory antioxidant capacity.
Shah said oregano ranks behind cinnamon on the ORAC scale. Its major bioactive components include flavonoids, thymol, carvacrol and phenolic acids.
Those compounds have been studied for several biological activities.
Bianchini said antioxidants found in oregano may contribute to immune support, while oregano oil has demonstrated antimicrobial and antifungal activity in research.
She also pointed to oregano’s potential relationship with the gut microbiome, where plant compounds can interact with bacteria involved in digestion and immune function.
Research on polyphenol-rich herbs and spices has similarly explored their ability to encourage beneficial gut bacteria and influence digestive and immune processes.
Flavonoids themselves can act in complex ways. A practitioner’s handbook addressing biochemical imbalances notes that some flavonoids can function as pro-oxidants under particular conditions, potentially participating in cellular signaling associated with apoptosis while also interacting synergistically with other antioxidant compounds.
As with cloves, the concentration matters.
Shah cautioned that oregano supplements can be particularly potent and recommended that concentrated products be used only with medical guidance. Bianchini similarly advised limiting oregano oil to short-term use when appropriate.
Ordinary dried or fresh oregano used in cooking is substantially different from concentrated oregano oil.
The value of herbs and spices also exists within the wider nutritional environment. Plant foods provide nutrients including zinc, selenium, iron, copper, folic acid and vitamins A, C, E and B, which Dr. Daniel Amen has discussed in connection with immune function and detoxification.
No single spice provides all of those nutrients, making dietary variety important.
Turmeric
Turmeric’s best-known compound is curcumin, a pigment and phytonutrient that has been extensively studied for antioxidant and anti-inflammatory activity.
Bianchini said curcumin can influence immune and inflammatory pathways and may reduce oxidative stress.
Research has explored curcumin in connection with metabolic syndrome, arthritis and anxiety, although additional studies are needed to determine the strength and clinical significance of those effects.
Scientists have also studied curcumin in muscle tissue.
A 2007 study published in the Journal of Cellular Biochemistry found that curcumin prevented lipopolysaccharide-induced increases in atrogin-1/MAFbx and associated muscle-mass loss under the experimental conditions examined.
Ordinary culinary turmeric contains considerably less curcumin than concentrated supplements. The report placed the amount at approximately 2% to 9% of the spice.
Crowe said that does not prevent turmeric from being useful in cooking because ground turmeric still provides concentrated plant compounds in relatively small servings.
Turmeric has a long history of use in Ayurvedic and Traditional Chinese Medicine. Modern research has subsequently investigated curcumin’s antioxidant and anti-inflammatory properties.
One limitation is absorption.
Isolated curcumin is poorly absorbed by the body on its own. Pairing turmeric with black pepper and dietary fat can increase its bioavailability, according to dietitians.
That increased absorption also provides another reason to exercise caution with concentrated preparations. High doses of curcumin can interfere with blood-thinning medications.
Curcumin is one of many phytonutrients researchers and natural-health practitioners have examined for possible incorporation into everyday dietary patterns.
Culinary Use Offers a Practical Approach
The antioxidant content of cloves, ginger, oregano and turmeric does not mean laboratory measurements should be interpreted as rankings of their effects on human health.
ORAC values measure the ability of substances to neutralize particular free radicals under controlled laboratory conditions. They do not determine how effectively those compounds survive digestion, enter circulation, reach tissues or interact with human metabolism.
Shah emphasized that limitation when discussing antioxidant measurements.
Dietitians therefore generally favor using herbs and spices as part of normal food preparation rather than relying on concentrated extracts solely because a particular ingredient produces a high antioxidant score.
For cloves, that could mean adding a pinch to oatmeal or yogurt. Ginger can be grated into meals or beverages. Oregano can season vegetables, sauces or proteins, while turmeric can be incorporated into soups, rice dishes and other foods.
Such culinary quantities can increase dietary exposure to a broad mixture of plant compounds without reaching the concentrations found in many supplements or essential oils.
Crowe, Bianchini and Shah all cautioned that concentrated preparations can behave differently from foods and may produce adverse effects or interact with medications.
The broader nutritional lesson is therefore not that one spice can prevent or treat disease, but that common seasonings can contribute meaningful phytonutrients to an otherwise balanced diet.
Cloves, ginger, oregano and turmeric each supply different antioxidant compounds, and incorporating them into everyday cooking offers a simple way to diversify plant intake without relying on high-dose supplements.
For people considering concentrated oils, extracts or supplements — particularly those taking medications or managing medical conditions — dietitians recommend consulting a health care professional first.
Moderation remains important even with nutrient-rich foods. Laboratory antioxidant potential can help identify interesting compounds for further research, but the benefits of a diet ultimately depend on how foods and nutrients function together inside the body rather than on any single ORAC score.
