Parsley
vs
Oregano

Summary

Oregano contains significantly more vitamins and minerals than parsley.

In recent years, parsley and oregano have been at the center of scientific attention. While parsley is more researched, both are excellent sources of antioxidants and vitamins in the daily diet.

Introduction

Herbs and spices are a perfect way to add a range of flavors to any dish. Both parsley and oregano are ideal herbs and spices.

Parsley belongs to the Umbelliferae family, also known as the carrot or celery family. On the other hand, oregano is botanically classified in the family of mints. Oregano owes its flavor to compounds such as thymol, carvacrol, ocimene, pinene, limonene, and caryophyllene.

In this article, we are going to compare parsley and oregano, focusing on their nutritional differences and health impacts.

Nutritional Content

Parsley is richer in vitamins C, K, and A. On the other hand, oregano contains higher amounts of vitamins E, B complex (B1, B2, B3, B5, and B6), and folate.

Vitamin Comparison

Vitamin comparison score is based on the number of vitamins by which one or the other food is richer. The "coverage" charts below show how much of the daily needs can be covered by 300 grams of the food.

When comparing their mineral profile, oregano is richer in phosphorus, iron, calcium, zinc, copper, magnesium, and potassium.

While both of these plants are low in sodium, oregano contains less.

Mineral Comparison

Mineral comparison score is based on the number of minerals by which one or the other food is richer. The "coverage" charts below show how much of the daily needs can be covered by 300 grams of the food.

Health Impact

Myricetin, a flavonoid found in parsley, helps prevent skin cancer (1).

Parsley can also decrease the risk of developing type 2 diabetes (2).

One study has shown the antiviral potential of oregano against norovirus infections (3).

Generally, parsley and oregano have protective roles against the following:

  • Cancer prevention (1, 4)
  • Antibacterial properties (5, 6)
  • Anti-inflammatory properties (7, 8)
  • Bone health improvement

Parsley has antiosteoporotic effects on bone tissue (9).

Cardiovascular health

Parsley has negative inotropic and chronotropic properties, leading to hypotensive activity. Additionally, it has a strong antiplatelet aggregation effect. These effects are crucial in reducing cardiovascular risk (10).

Oregano may also lower blood pressure by increasing endothelial NO, an important vasodilator, and binding PPARγ. This effect is distinct from parsley's mechanisms (11).

Furthermore, both parsley and oregano have a diuretic effect, which can be beneficial for managing hypertension and heart failure (12, 13).

It should be noted that oregano oil (at doses of 100 and 200 mg/kg) reduced the incidence of cardiac complications in rats with doxorubicin-induced myocardial infarction (14).

According to this study, oregano's anti-inflammatory properties may help prevent atherosclerosis. Further research is needed to confirm these findings (15).
