Here I will cover two things that we can do to increase out health, and they are simple. First, smelling the herb rosemary can improve memory:

“In 1987 the journal Planta Medica published the first study discussed here on the impact of rosemary on mice. This study was carried out by four scientists, and found that levels of the 1,8-cineole found in blood, and locomotion capabilities, were both elevated after the mice inhaled rosemary oil. Cineole is also known as eucalyptol, which is the compound making up most eucalyptus oils. Next came a study performed in 1998, conducted by the International Journal of Neuroscience. In this study, nine researchers from the University of Miami School of Medicine applied their curiosity to humans, rather than rats. They exposed 40 adults to several minutes of aromatherapy, some receiving rosemary, while the others received lavender, all while they worked on math equations. They discovered that those who received the lavender therapy were relaxed, but drowsy. And even though they did better with the math problems with the therapy, those with the rosemary therapy performed markedly better. They were far more alert and less anxious, as well as finished solving the problems much quicker.
