Best of all, it’s pretty easy to find and can even be made at home using just a few ingredients. Find out below about the benefits and uses of this oil and how to prepare it at home .

12 benefits found in rosemary oil

1. Improves skin appearance

Rosemary oil, if applied to the skin, helps improve the appearance and health of the area for a number of reasons.

The first is that it treats acne . It can be used to soften the appearance of pimples, as it is a powerful natural anti-inflammatory. ( 1 )

Another point that makes this oil a natural option for taking care of acne-prone skin is the fact that it accelerates the healing process, stimulating the production of cells that make up the epithelial tissue. In fact, this action is great to prevent scarring caused by acne. ( 2 )

The compounds found in the aromatic herb also have bactericidal potential against strains (set) of bacteria that live on the skin and are responsible for causing acne.

The oil is also rich in vitamin C (ascorbic acid), a nutrient that acts as an antioxidant. In other words, it prevents cell degradation, which is excellent in preventing wrinkles , as well as protecting against the sun’s rays.

This vitamin also plays an important role in the production of collagen , a type of protein that promotes skin firmness and elasticity.

Finally, its oily formula forms a kind of protective film on the skin, which prevents the moisture from the most superficial layers to evaporate. Thus, maintaining hydration for much longer, but without leaving the area oily, as it is quickly absorbed. ( 3 )

2. Accelerates hair growth and treats dandruff

Rosemary oil is also used to stimulate hair growth. Mix the oil to shampoo or apply it by massaging the scalp can help solve the excessive drop wires , to promote the circulation of the scalp. ( 4 )

This action is mainly derived from the presence of two types of organic acids: caffeic and rosmarinic. Together, they decrease the production of sebum (fat), unclogging the pores , which also stimulates growth and treats oiliness in the scalp. ( 5 )

Rosemary is still a powerful antifungal, which is why it can treat seborrheic dermatitis , a disease that causes flaking of the skin and is known by the popular name of dandruff. ( 6 )

3. Promotes relief from colds and flu

The oil can also be ingested, as long as the maximum amounts per day are respected, and it becomes a natural way to treat the flu and the common cold, as it has the ability to prevent the replication of the virus that causes it. ( 7 )

It relaxes the airways , relieving problems such as a runny nose , coughing and facilitates the expulsion of mucus (phlegm) that is produced from an inflammatory response by the body against the invasion of viruses. ( 4 )

4. Favors circulation

Using rosemary oil in your diet can also increase blood circulation. The compounds found in it widen the vessels through which the blood passes, the so-called vasodilator effect. Because of this, the blood is able to flow more smoothly. ( 8 )

This process can prevent problems such as hypertension and varicose veins , which are quite common circulatory disorders. It also has antithrombotic properties, preventing the formation of thrombi, which impede the free circulation of liquid and lead to death in more severe cases. ( 3 )

5. Relieves cramps

Using rosemary oil brings quick relief from cramps , both intestinal and menstrual, by reducing muscle spasms responsible for pain.

In addition, it is also an analgesic and works by blocking the pain stimuli being sent to the brain. ( 7 )

6. Reduces and controls blood glucose

Have you ever heard that rosemary “lowers” ​​blood glucose? Research has linked this to the herb’s potential to increase the cells’ consumption of sugar, thus stimulating the burning of this nutrient and consequent elimination from the body. ( 7)

The oil not only lowers blood glucose, but also prevents excess sugar , which characterizes diabetes mellitus, from causing damage to organs such as the kidneys and liver, which are more overloaded by the extra effort to eliminate high doses of toxins. ( 9 )

7. Alleviates the migraine

The oil, when consumed or used in aromatherapy, can also relieve migraines and this is because it is rich in compounds that boost brain functions. ( 8 )

The oil “encourages” the release of serotonin , a type of neurotransmitter responsible for regulating mood and sleep. His deficiency is related to a greater risk of suffering from this type of pain. The compound acts similarly to a pain reliever. ( 3 )

8. Puts an end to bad breath

Rosemary oil has compounds that prevent the bacteria that cause halitosis (bad breath) from proliferating in the mouth. ( 10 )

The herb, when used diluted in water as a mouthwash , has the potential to eliminate microorganisms and plaque, the main causes of periodontitis , a type of infection that attacks the gums and has bad breath among its symptoms and can even lead to tooth loss. ( 11 )

9. Improves memory

The oil is able to stimulate brain activities and connections, because the herb inhibits the release of an enzyme known as acetylcholinesterase.

This substance, with a very complicated name, is responsible for degrading the neurotransmitter acetylcholine, which is responsible for sending nerve impulses and information.

With a greater amount of acetylcholine, communication between different parts of the brain is faster, making it easier to store and access memories of everyday events.

To further increase the effect on memory, rosemary also enhances the state of attention, which re-establishes the process of retaining new information. ( 3 )

10. Relieves anxiety

By increasing the production of the “pleasure hormone”, rosemary helps to relax , being of great help in controlling anxiety and stress. Its effect is very similar to that of fluoxetine, a synthetic antidepressant. ( 7 )

11. Decreases swelling caused by fluid retention

The swelling caused by fluid retention, common to appear in the premenstrual period due to hormonal changes, can be reduced with the addition of rosemary oil in your diet, as it is a great natural diuretic .

That is, it drives the kidneys to produce more urine, which eliminates not only excess fluids in the body, but also toxins that make the swelling problem worse. ( 7 )

12. Keeps insects away

Rosemary oil keeps away insects and mosquitoes, even Aedes aegypti , the mosquito that transmits dengue, Zika and chikungunya.

The repellent effect is due to the presence of alpha-terpinene, a substance that has an unpleasant aroma and is toxic to several types of insects. That’s why when they smell the smell they don’t come closer. ( 3 )

How to prepare rosemary oil at home?
