Botanical and Nutritional Profile
Thyme is a wild shrub that thrives in the Mediterranean climate. It is rich in phytonutrients, minerals, and vitamins, making it a valuable addition to diets. The herb is known for its pungent taste and is loaded with moisture, proteins, crude fiber, and essential minerals1. The chemical composition of thyme can vary depending on its geographical location, but it predominantly contains flavonoids and antioxidants1.
Chemical Composition
The primary bioactive compounds in thyme include thymol and carvacrol, which are essential oils known for their therapeutic properties. Additionally, thyme contains polyphenols such as scutellarin, rosmarinic acid, scutellarein, apigenin-7-O-glucuronide, gallic acid, and ferulic acid2. These compounds contribute to thyme’s antioxidant, anti-inflammatory, and antimicrobial activities.
Therapeutic Properties of Thyme
Thyme has been extensively studied for its therapeutic effects. Its essential oils, particularly thymol and carvacrol, exhibit multi-pharmacological properties, including antioxidant, anti-inflammatory, and antineoplastic actions1. Thyme is also known for its antiviral, antibacterial, antifungal, and antiseptic activities, making it a potent natural remedy for various ailments1.
Anti-inflammatory and Antioxidant Effects
Thyme’s polyphenols have shown promising results in mitigating intestinal inflammation and protecting the intestinal barrier in ulcerative colitis models2. The herb’s essential oils have also demonstrated significant antioxidant and anti-inflammatory effects, particularly in respiratory conditions such as bronchial asthma5 and lung inflammation7.
Antimicrobial Activity
Thyme’s antimicrobial properties make it a valuable natural preservative in the food industry. Studies have shown that thyme extracts and essential oils can increase the stability and reduce lipid oxidation in various food products, including meat, milk, and fish3. Additionally, encapsulated thyme essential oil has been used successfully as a natural preservative in bakery products, extending their shelf life without synthetic additives10.
Applications in Food and Pharmaceuticals
Thyme’s bioactive compounds have garnered attention for their potential use in the food industry as natural antioxidants and antimicrobials. The herb’s ability to enhance the shelf life and stability of food products aligns with the growing consumer demand for natural and healthier alternatives3. In the pharmaceutical industry, thyme’s therapeutic properties are being explored for the treatment of respiratory diseases, inflammatory conditions, and even cancer6 7.

Adverse Effects of Thyme
Cytotoxicity and Inflammation Modulation
Thyme extract has shown cytotoxic effects on human lung cancer cells and modulated inflammatory responses, indicating potential adverse effects when used in high concentrations or for prolonged periods2.
Hepatotoxicity
Thyme oil and thymol have been studied for their ability to counteract doxorubicin-induced hepatotoxicity. While they showed protective effects, the study highlights the potential for thyme components to interact with other medications and affect liver function4.
Accumulation of Thymol in Animal Tissues
In broiler chickens, high dietary levels of thyme led to increased thymol concentrations in gut contents and plasma, although levels in liver and muscle tissues were low. This suggests potential bioaccumulation and the need for caution in dietary use6.
Impact on Seed Germination and Plant Growth
Exposure to cadmium significantly reduced thyme seed germination and initial seedling growth, indicating that thyme plants can be sensitive to environmental contaminants, which may affect their quality and safety for consumption1.

How has Thyme Improved Patient Outcomes?
Management of Radiation-Induced Oral Mucositis
Thyme honey significantly reduced the severity of oral mucositis in head and neck cancer patients undergoing radiotherapy, improved their global health, and maintained body weight, leading to a better quality of life compared to saline rinses1.
Anti-Inflammatory and Antioxidant Effects
Thyme oxymel improved inflammation, oxidative stress, and lipid metabolism in rats with diet-induced obesity, suggesting potential benefits in managing metabolic disorders2.
Thyme polyphenols alleviated ulcerative colitis in mice by reducing intestinal inflammation, protecting the intestinal barrier, and regulating gut microbiota3.
Thyme essential oil reduced respiratory symptoms in COVID-19 patients, including fever, cough, and fatigue, and improved immune markers4.
Thyme oil alleviated bronchial asthma symptoms in rabbits by modulating inflammatory cytokines and reducing oxidative stress5.
Thyme extract showed anti-inflammatory properties in human bronchial and tracheal epithelial cells and demonstrated cytotoxic effects on lung cancer cells6.
Respiratory Health
Thyme extract increased mucociliary-beating frequency in COPD patients, suggesting improved airway clearance and potential therapeutic use in respiratory disorders7.
Bone Health
Thyme supplementation in rats with low calcium intake prevented osteoporosis by improving bone mineral density and reducing inflammation and oxidative stress10.

Thyme Mechanisms of Action
Anti-inflammatory and Antioxidant Effects
Thyme polyphenols and essential oils exhibit significant anti-inflammatory and antioxidant properties by inhibiting the NF-κB signaling pathway and reducing pro-inflammatory cytokines such as IL-1β, IL-6, IL-8, and TNF-α1 2 4 10.
Thymol, a major component of thyme, enhances the activity of antioxidant enzymes like catalase (CAT) and superoxide dismutase (SOD), contributing to its overall antioxidant capacity4 7 8.
Gut Health and Microbiota Modulation
Thyme polyphenols improve gut health by upregulating tight junction proteins, enhancing intestinal epithelial cell integrity, and modulating gut microbiota. They increase the abundance of beneficial bacteria and decrease harmful bacteria, which is beneficial for conditions like ulcerative colitis1.
Lipid Metabolism and Obesity
Thyme oxymel and extracts have been shown to ameliorate obesity and dyslipidemia by improving lipid profiles, reducing oxidative stress, and regulating weight-related hormones. They also modulate the expression of genes involved in lipid metabolism, such as SREBP-1c and CPT-12 7.
Antimicrobial Activity
Thyme essential oil exhibits strong antimicrobial properties, particularly against resistant bacterial strains like Pseudomonas aeruginosa and Listeria monocytogenes. It disrupts microbial biofilms and inhibits flagellar synthesis and motility in bacteria4 9.
Respiratory Health
Thyme extracts have broncholytic and secretomotoric effects, improving mucociliary clearance and relaxing smooth muscles in the trachea and ileum. These effects are partly mediated through interactions with beta-2 receptors3 5.
Cytotoxic and Anticancer Properties
Thyme extracts show cytotoxic effects on lung cancer cells and reduce inflammatory signals, suggesting potential use in cancer therapy. They modulate the release of pro-inflammatory cytokines and downregulate NF-κB proteins in cancer cells10.
