The main benefits of rosemary

1. Provides good memory
In aromatherapy, rosemary is used as an essential oil to reduce stress, increase clarity of thought, and improve mood.
However, recent research indicated that the herb also works by stimulating memory.
The study carried out memory tests on 150 people 65 and older. They were placed in different rooms, some flavored with rosemary. After that, they were asked a series of questions to test their ability to remember to do something at a certain time, such as taking medication.
Those who were subjected to the smell of rosemary had a performance in the memory test 15% higher than people placed in a place without aromatization. The results indicate that inhaling the herb can increase the ability to stay alert.
2. Benefits of rosemary for brain function

In another study, it was observed that rosemary can improve the cognitive function of the elderly. However, more research is still needed to evaluate the effects of the herb and how to administer it effectively.

Due to the fact that it has a large amount of antioxidant substances, the researchers seek to analyze whether rosemary would be useful for the treatment of serious diseases, such as cancer, for example.
Studies with rats indicate that the plant could be used to reduce the formation of cancer cells responsible for skin cancer.

In addition to the elements mentioned, there are several abilities that rosemary has, but there is still no research that has tested these effects.
Due to the presence of minerals such as potassium, calcium and magnesium, the herb would have a diuretic action and facilitate digestion. Rosemary tea, for example, can be used to relieve intestinal gas formation and promote good liver health.
The drink would also be very helpful in fighting the symptoms caused by PMS or PMS, as it would relieve colic and reduce stress and nervousness.

Rosemary is very versatile and can be used in many ways. In food, it can be added in sauces, breads and seasonings for roasts and vegetables. It is also possible to make tea or put the herb in vitamins and juices.
Other forms of use are for the preparation of baths, scalding feet or even as an essential oil for massages and aromatherapy. To strengthen the hair, a good tip is to put five drops of rosemary essential oil in coconut oil and massage the scalp with the mixture.
