Chemical Composition and Nutritional Profile

Oregano contains a rich array of bioactive compounds, including phenolic compounds, flavonoids, terpenes, and essential oils, with carvacrol and thymol being the primary active components that contribute to its potent antimicrobial and antioxidant properties.

It is also a good source of vitamins such as vitamin C, vitamin A, and several B-complex vitamins, along with minerals like iron, calcium, and magnesium, which support various physiological functions. The essential oils in oregano act by disrupting microbial cell membranes and inhibiting the growth of bacteria, fungi, and viruses, while its high antioxidant content helps neutralize free radicals and reduce oxidative stress in the body.

Additionally, oregano's flavonoids and other polyphenols contribute to its anti-inflammatory and immune-boosting effects, making it a valuable herb in both culinary and medicinal applications.

Safety, Side Effects and Contraindications

Origanum vulgare, commonly known as oregano, is generally considered safe when used in moderate amounts as a culinary herb or in herbal supplements.

However, in higher doses, it may cause gastrointestinal side effects such as nausea, vomiting, or heartburn due to its high concentration of essential oils. It may interact with certain medications, including anticoagulants and antiplatelet drugs, potentially increasing the risk of bleeding, and should be used cautiously with other herbs like garlic or ginkgo biloba. Pregnant and breastfeeding women should avoid excessive consumption due to potential risks to fetal or infant development, while individuals with chronic conditions like diabetes or hypertension should consult a healthcare provider before use.

To ensure safety, it is advisable to use oregano in moderation, consult a healthcare professional before starting any supplement regimen, and avoid prolonged or high-dose use without medical supervision.

Growing, Harvesting and Storage

Origanum vulgare grows best in well-drained, fertile soil that is slightly alkaline to neutral, with a pH range of 6.

0 to 7. 5, and requires full sun exposure for optimal growth and essential oil production. It thrives in temperate climates and prefers moderate watering, allowing the soil to dry slightly between waterings to prevent root rot. Regular pruning and weed control are essential for maintaining plant health and promoting bushier growth, while mulching helps retain soil moisture and suppress weeds. The best time to harvest is during the flowering stage, typically in late summer, by cutting the stems just above the leaves to preserve the aromatic oils.

To preserve its potency, the harvested material should be air-dried in a shady, well-ventilated area, then stored in airtight containers in a cool, dark place or refrigerated to extend its shelf life.
