A pooled analysis of 21 meta-analyses, including 139 placebo-controlled comparisons, found cinnamon supplementation associated with lower HbA1c, total cholesterol, LDL cholesterol, and blood pressure, according to a report published in Frontiers in Nutrition [1].

But cloves, ginger, oregano, and turmeric also contain high antioxidant levels, according to registered dietitians Seema Shah, Amanda Crowe, and Jennifer Bianchini.

Antioxidants are compounds that neutralize free radicals, which can weaken the immune system and lead to various diseases, according to a NaturalNews.com report [2]. On a per-gram fresh-weight basis, herbs rank higher in antioxidant activity than fruits and vegetables, according to a 2015 report by Dr. Mercola [3].

The U.S. Department of Agriculture's (USDA) ORAC, or Oxygen Radical Absorbance Capacity, database measures antioxidant potential in laboratory settings and has listed items such as unprocessed cocoa beans, cinnamon, and pecans among the top-ranked foods [4].

Shah said ORAC is one laboratory measure of antioxidant capacity, though it does not show how the body absorbs or uses antioxidants. Common kitchen herbs and spices contain high amounts of bioactive compounds with antibacterial, antifungal, antiviral, antioxidant, and anti-inflammatory properties, according to a report from NaturalNews.com [5].

Cloves

Ground cloves have a higher ORAC score than cinnamon, according to Shah. The antioxidants in cloves include eugenol, flavonoids, and gallic acid [18].

A 2025 study found that clove pod antioxidants may be effective at lower doses, and eugenol may have antibacterial properties. The antioxidant property of clove has been examined in animal research; a 2005 study published in the Journal of Applied Toxicology examined the antioxidant property of black cumin and clove in rats during aflatoxicosis [6].

Crowe said a small pinch in yogurt, oatmeal, or baked goods provides a concentrated dose, and whole cloves work in simmered drinks [18].

Cloves, cinnamon, oregano, thyme, and sage may provide practical antioxidant support with better absorption than turmeric's curcumin, though experts caution that concentrated supplements and oils should be used under guidance, according to a report by YourNews [7].

Shah said high doses of cloves, over one-fourth teaspoon ground, may be harmful to the liver.

The report stated that culinary herbs and spices have very low calorie content and have been widely used for their hypoglycemic, lipid-lowering, and anti-inflammatory activities, according to a text on the antioxidant properties of spices and herbs [8].

Ginger

Fresh and ground ginger offer benefits, but fresh ginger has additional aromatic compounds, Crowe said [18]. Ginger contains gingerol, which converts to shogaols when dried; both may have anti-inflammatory and anti-tumor properties, studies suggest.

A 2020 research review found ginger can trigger anti-inflammatory cytokines and reduce pro-inflammatory ones, according to the research. A recent study published in Nutrients found that common culinary herbs and spices, including ginger, enhance beneficial gut bacteria, according to a NaturalNews.com report [9].

Ginger is among the spices that have been used as medicines in ancient Egypt and Asia and as food preservatives in ancient Rome and Greece, according to a text on the antioxidant properties of spices and herbs [8].

The medicinal power of herbs and spices has been described by integrative doctors as "The Kitchen Pharmacy," with spices like turmeric, ginger, cinnamon, and black pepper packed with antioxidants, anti-inflammatory compounds, and disease-fighting nutrients [10].

Bianchini said ginger is safe in typical recipe amounts, but concentrated supplements may cause digestive upset or interact with medications [18]. Many researchers now believe that coronary heart disease is linked to a lack of dietary antioxidants, which protect circulating fats from oxidation, according to Sarah Brewer's book on nutrition [11].

Oregano

Oregano ranks after cinnamon in ORAC score, according to Shah. It contains flavonoids, thymol, carvacrol, and phenolic acids [18].

Flavonoids may also act as pro-oxidants, signaling appropriate apoptosis and preventing tumor growth, as well as acting synergistically with other antioxidant compounds, according to a practitioner's handbook on biochemical imbalances [12].

According to Bianchini, oregano antioxidants may support immunity, and oregano oil has shown antimicrobial and antifungal properties. Bianchini also said oregano helps balance gut bacteria and the microbiome.

A NaturalNews.com report on boosting gut health naturally noted that polyphenol-rich herbs and spices enhance beneficial gut bacteria, improve digestion, and support immune function [9].

Shah said oregano supplements are very strong and should only be used under medical supervision. Meanwhile, Bianchini advised short-term use of oregano oil.

Nutrients found in plant foods, such as zinc, selenium, iron, copper, folic acid, as well as vitamins A, C, E, and B, support a strong, disease-fighting immune system and aid in detoxification, according to Dr. Daniel Amen's book on brain health [13].

Turmeric

Bianchini said turmeric's key antioxidant is curcumin, which supports the immune system and inflammation pathways and decreases oxidative stress. Studies have linked curcumin to improvements in metabolic syndrome, arthritis, and anxiety, though more research is needed, according to the report.

Curcumin has also been studied for its effects on muscle mass; a 2007 study in the Journal of Cellular Biochemistry found curcumin prevents lipopolysaccharide-induced atrogin-1/MAFbx upregulation and muscle mass loss [14].

Culinary turmeric contains about 2-9% curcumin, lower than cinnamon and cloves, according to the report. Crowe said ground turmeric powder contains concentrated antioxidants, so small amounts are effective in cooking.

Turmeric has been revered in Ayurvedic and Traditional Chinese Medicine, and modern science confirms curcumin is a powerhouse antioxidant and anti-inflammatory agent, though isolated curcumin is notoriously difficult for the body to absorb, according to a NaturalNews.com report [15].

Pairing turmeric with black pepper and fat increases bioavailability, and high doses can interfere with blood thinners, according to dietitians. Curcumin is among the phytonutrients that can be incorporated into daily routines, as noted in a Brighteon broadcast on hidden health secrets [16].

Conclusion

Cloves, ginger, oregano, and turmeric are common spices with antioxidant properties, according to dietitians. Shah said laboratory measures such as ORAC do not necessarily translate to human health benefits. The ORAC database measures antioxidant potential in a laboratory setting, but it does not show how the body absorbs or uses antioxidants [4].

Dietitians recommended culinary use and medical consultation before using concentrated supplements. Crowe advised using small amounts in cooking, such as a pinch of cloves in oatmeal or ground turmeric in soups.

Bianchini and Shah both cautioned that concentrated supplements and oils can be very strong and should be used under medical supervision.

For those seeking to incorporate more antioxidant-rich spices into their diet, natural health advocates recommend using them in everyday cooking rather than relying on concentrated pills. As one report noted, adequate phytonutrient intake is important for overall health, but moderation is key [17].
