What is rosemary?

Rosemary, scientifically known as Rosmarinus officinalis, is a woody, perennial herb, with needle-like leaves that are evergreen and fragrant. This plant, native to the Mediterranean region, has small flowers of pink, purple, white or blue colour.

Its name derives from Latin and can be translated as “dew of the sea”. Besides, rosemary is one of the most popular aromatic herbs within the Mediterranean culinary traditions and nowadays, it can be found in almost any cuisine of the world.

This plant, a member of the mint family Lamiaceae, has a warm, bitter and slightly astringent taste. Nevertheless, it provides a delicious flavour and aroma to all kinds of recipes, such as roasts, stews, sauces or meets.

Another of the benefits of rosemary is its versatility. The leaves of this shrub can be eaten both fresh and dry, as well as in teas, alcohol or essential oil, among others.

Considered a sacred herb by ancient Romans, Greeks, Egyptians and Hebrews, rosemary has become increasingly popular in traditional medicine for its properties and health benefits.

The rosemary herb is a great source of antioxidants and anti-inflammatory agents. According to research, this plant can improve blood circulation  and also strengthen the neutralization of free radicals.

These chemicals are highly reactive elements that inject oxygen into the cells and cause oxidation, which accelerates the aging of the organism. So, inhibiting its action delays this process.

2. Antibacterial properties

The antibacterial and antimicrobial properties of rosemary have turned it into one of the main medicinal plants used within the Mediterranean culture.  

This herb is highly effective against bacterial infections  and it has been closely related to the prevention of staph infections.

All the active components of rosemary that were previously mentioned (antioxidants, anti-inflammatory and antibacterial agents) help the correct functioning of the immune system, boosting their action on those pathogens that can become a threat to your health. 

4. Reduces Cough

Rosemary leaves are able to remove the phlegm and mucus from the respiratory system. This provides relief against cough in catarrhal processes, colds, flu and even as an adjuvant treatment of asthma.

According to the principles of aromatherapy, the different scents of essential oils can, among other things, be beneficial to your psychological state.

In view of this, it is known that the aroma of rosemary is associated with stress-reducing and relaxing effects in people with symptoms of anxiety and/or depression. This may be due to the fact that this herb reduces the levels of cortisol, which helps ease tension.
