Benefits of rosemary

Research on rosemary and memory

The University Northumbria (United Kingdom) carried out a meticulous study with which they have shown that a high concentration in blood of one of the components of rosemary, 1,8-cineol, improves cognitive performance, specifically the speed and accuracy of responses.

This component is absorbed through the nasal mucosa and lungs, crosses the blood brain barrier and all points to inhibits the enzyme acetylcholinesterase. It prevents the breakdown of the neurotransmitter acetylcholine. It is widely distributed in the human brain and necessary to learn, memorize and concentrate

So if you are preparing exams cut a twig of the plant and put it in a glass of water on the desk, or we can also use the essential oil of rosemary and put a couple of droplets near the nose, to improve our memory. Rosemary not only serves stomach problems, hair loss and hypertension, it is also excellent for memory.

Rosemary to combat stress and inflammation

The free radicals that produce oxidative stress are directly associated with inflammation, aging and carcinogenesis. The body has several anti-oxidative systems and saliva is one of those systems. In a study of the benefits of rosemary, the researchers found that smelling lavender and rosemary oils in aromatherapy increased saliva production and significantly reduced levels of the stress hormone cortisol. They concluded that these oils could protect the body from stress. Other studies confirmed that rosemary leaves are potent anti-inflammatory and anti-tumor effects. Rosmarinic acid increases the production of prostaglandin E2 (substance that helps in the contraction and relaxation of muscle, dilation and constriction of blood vessels, control of blood pressure, and modulation of inflammation) and reduces leukotriene production B4 involved in inflammation.

Rosemary to prevent cancer

Rosemary has been reported to have a major role in reducing cancer risk. One study found that rosemary extract, which contains carnosol, carnosic acid, ursolic acid and rosmarinic acid, can suppress the development of tumors in various organs including the colon, breast, liver, stomach, as well as melanoma and leukemia cells. It was found that anti-carcinogenic properties arise from molecular changes in the multi-stage processes of cancer development.

Rosemary to treat gastrointestinal problems

Rosmarinic acid in rosemary relaxes the muscles in the trachea and intestine, stimulates the production of bile, and protects the liver. In folk medicine, it is used as an antispasmodic in renal colic. The researchers suggest that rosmarinic acid also has therapeutic potential in the treatment and prevention of peptic ulcer and liver toxicity.

Rosemary for hair growth

One of the traditional uses of rosemary oil is to promote hair growth, although there is not much scientific evidence to prove this. However, a recent study in mice showed that topical administration of rosemary leaf extract improved re-growth of hair in mice that experienced an arrest in hair growth induced by a testosterone treatment, suggesting an anti-inflammatory activity. The study concluded that rosemary is a promising plant for hair growth.

Rosemary to lose weight and lose weight.

The rosemary turns out to be one of the most potent herbs as a natural antibiotic. Like its relatives the Mint, Salvia and Thyme, which are all plants of the Labiatae family, have an exquisite aroma and medicinal properties.

The power of rosemary as an antibiotic is greater than that of the other herbs thanks to that it possesses carnosol or carnosolic acid which is a very potent antimicrobial agent.

That is why it is so recommended in the case of intestinal infections, and is even used as part of the treatment of some venereal diseases.
