Benefits of Rosemary for Brain Function

 Benefits of Rosemary for Brain Function in Hamlet, Act, 4, Scene, 5, Ophelia notes that rosemary is for remembrance, an idea that goes back at least a few thousand years to the ancient Greeks who claimed that rosemary comforts. The brain sharpens understanding, restores lost memory and awakens the mind. After all, plants can be considered little chemical factories that manufacture all sorts of compounds that could have neuroprotective benefits. So let’s cut down on processed foods and eat lots of phytonutrient-rich whole plant foods, including perhaps a variety of herbs. Even the smell of certain herbs may affect how our brain works. Unfortunately, I’ve found much of the aromatherapy literature scientifically unsatisfying, like there’d, be studies like this, offering subjective impressions and so fine sure sniffing. An herbal sachet is indeed easy, inexpensive, and safe, but is it effective? They didn’t compare tests, scores, or anything Even when there was a control group where researchers had people do a battery of tests in a room that smelled like rosemary, lavender, or nothing, and even when they did compare test results. The lavender appeared to slow them down, and impair their performance, whereas the rosemary group seemed to do better, But maybe that’s just because of the mood effects. Maybe the rosemary group did better just because the aroma kind of pepped them up And not necessarily in a good way, maybe kind of overstimulating. In some circumstances, there have been studies that measured people’s brain waves and were able to correlate the EEG findings with the changes in mood and performance, along with objective changes in stress hormone levels. But is this all just because pleasant smells improve people? S moods Like if you created some synthetic rosemary fragrance with a bunch of chemicals that had nothing to do with the rosemary plant. Would it still have the same effect We didn’t know until now that aromatic herbs do have volatile compounds that theoretically could enter the bloodstream by way of the lining of the nose or lungs and then potentially cross into the brain and have direct effects? But this was the first study to put it to the test. They had. People do math in a cubicle infused with rosemary aroma, and so yes, they got that same boost in performance, but for the first time showed how much better they did correlate with the amount of a rosemary compound that made it into their bloodstream. Just from being in the room, and so not only did this show that it gets absorbed, but that such natural aromatic plant compounds may be playing a direct effect on changes in brain function.  If that’s just what smelling it can do? What about eating rosemary? We have studies on alertness and cognition and reduced stress hormone levels, by inhaling rosemary. However, there were no clinical studies on cognitive performance following ingestion of rosemary. Until now, Older adults, average age 75 were given two cups of tomato juice, with either nothing or a half. A teaspoon of powdered rosemary, which is what one might use in a typical recipe, or a full teaspoon, two teaspoons, or over a tablespoon of rosemary powder, and they even gave them some placebo pills to go with it to even further eliminate any placebo effects. Speed of memory is a potentially useful predictor of cognitive function during aging, and what they found is that the lowest dose had a beneficial effect, accelerating their processing speed, but the highest dose impaired their processing speed, maybe because the half-teaspoon dose improved alertness, while the 4 Teaspoon dose decreased alertness, So rosemary powder at the dose nearest to normal, culinary consumption demonstrated positive effects on speed of memory. The implicit take-home message being more isn’t necessarily better. Take high doses of herbal supplements extracts tinctures, just cooking with spices is sufficient. A conclusion, no doubt pleasing to the spice company that sponsored the study. No side effects were reported, but that doesn’t mean you can eat the whole bush.This poor guy swallowed a rosemary twig which punctured through the stomach into his liver, causing an abscess from which 2 cups of pus and a 2-inch twig were removed, so explore herbs and spices in your cooking Branch out. Just leave the branches out.As found on YouTubeNatural Synergy $47.⁰⁰ New Non-Invasive Alternative.

How Chronic Stress Harms Your Body

[♩ INTRO ] Stress happens. And that’s not always bad—starting a new job or getting married can both be happy things, but they also can be really stressful. There are some kinds of stress that just don’t seem to go away, though. Like the feeling that you’re drowning in work, but still perpetually worried about making ends meet. If you deal with a lot of stress every day, for months or years on end, then stress doesn’t just feel awful—it actually causes you physical harm. Psychologists call any event or situation that puts pressure on you or threatens your well-being a stressor, while stress refers to your psychological and physical reactions. Stressors that are one and done—like locking your keys in your car, or forgetting your wallet—bring on acute stress. But when stressors are repeated or continuous, that’s chronic stress.

Things like abusive relationships, living in poverty, and being discriminated against have all been shown to cause chronic stress. And that psychological anguish takes a toll physically. When you experience acute stress, your body activates a system called the hypothalamic-pituitary-adrenocortical axis, or just HPA axis because why would you want to say all that other stuff over and over again. It starts deep in your brain, in the limbic system — the part responsible for a lot of your automatic emotional reactions, among other things. There, a region called the hypothalamus releases hormones that start a whole chain of more hormones being released — first by your pituitary gland, and then by your adrenal glands, which release a bunch of adrenaline and cortisol into your bloodstream. And those two hormones trigger the “fight-or-flight” response. They boost physical activity by increasing your blood sugar and the blood flow to your muscles, and bump up your metabolism at the same time.

The idea is that the physical boost helps you fight the stressor or run away. So, like, if you were suddenly face to face with a bear, the surge in energy would help you either outrun it, or go all like Revenant on it. The same system is activated by chronic stress, but things get a bit more complicated. Researchers have found that people under some kinds of chronic stress have perpetually high cortisol levels, as if their HPA axis is running constantly. For others, it can depend on the timing, with higher cortisol levels near the start of the stress before it actually dips lower than usual.

But we do know that while this stress reaction can be helpful at times, having it running all the time is a problem. People under chronic stress are at higher risk for all kinds of ailments, like heart disease, autoimmune diseases, and mental disorders like anxiety and depression. That’s because, in addition to it being super unpleasant to be stressed out all the time, the stress response is constantly sapping your energy. The resources used by fight-or-flight have to come from somewhere, and one of the places they come from is your immune system.

On the molecular level, the same cortisol that works to get extra glucose to your muscles also stops your body from making as many infection-fighting white blood cells as it normally would. So stress can tank your ability to fight infections. It's kind of like evolution is telling your body not to worry about fighting off that cold right now, because you need to fight that bear that is right in front of you. Except with chronic stress, the bear isn’t a bear. It’s your crappy job. Or your unhappy relationship. Or whatever it is that stresses you out all the time. And that means your immune system never gets the chance to recover and deal with that cold as easily as it normally would. One famous experiment demonstrating this involved 11 dental students who volunteered to have their mouths biopsied twice: first during summer vacation, and then again during exam week.

It took an average of 3 days longer for the wounds to heal while they were stressed about exams. All kinds of other studies have gotten similar results — some by punching small holes in people like they did with the dental students, and others by observing how stress affects recovery from surgery and other major wounds. There's also research suggesting that chronic stress explains part of the relationship between poverty and health.

Even just the perception of being in a lower socioeconomic class is associated with an increase in respiratory infections. Stress can also advance the aging process. By the time you get older, your DNA has had to replicate so many times that the protective parts at each of the ends of the chromosome, called telomeres, can kind of start to fray. When telomeres are shorter, it's more likely that there will be errors in copying genes. And those errors increase your risk of disease. There’s evidence that having more cortisol in your blood interrupts the repair of telomeres. Which might explain why stress is linked to diseases that are also associated with age, like heart disease, cancer, and anemia.

To stay healthy, the best thing you can do is get rid of the chronic stress. But, easier said than done. If you can’t get rid of it completely, things like meditation and relaxation therapies can help lower your stress response. And, weirdly enough, so might changing how you think about stress. Studies have shown that when people think about the source of stress as a challenge to overcome instead of a threat to their well-being, that seems to lower their perceived stress and reduce their body’s physical response. There’s another way you might be able to improve your health, too: help others reduce their stress. In a sample of over 800 older adults, those with high stress who also reported helping friends or neighbors with things like housework or childcare had mortality rates similar to those with low stress. Whereas those with high stress who didn’t help out had reduced odds of survival. So, chronic stress is not good for anyone. But even if you can’t avoid being stressed out all the time, there are ways to help yourself relax — and sometimes you can even reduce other people’s stress in the process.

The Long-term Effects of Stress

This video is intended to spread awareness about the long-term effects of stress. Everyone experiences stress everyday, it can come from any source. Some examples include emotional, physical or job related stress. Stress is our body’s primitive way of responding to any kind of internal or external demand or threat. The short-term effects of stress may not be serious but prolonged exposure to stress can lead to very serious long-term effects on the body. Thus, this video will be outlining the some of the long-term effects on the body such as an increase in heart attacks, obesity and development of diabetes. This video will also be discussing the three stress hormones; cortisol, epinephrine and norepinephrine. Cortisol, which is the major stress hormone, is released from the adrenal cortex. Epinephrine which is also referred to as adrenaline and norepinephrine, referred to as noradrenaline are released from the adrenal medulla.This video was made by 4DM3 students Vyshnavi Mahendran, Tamandeep Khangura, Humaira Nakhuda, Mateen Akhtar and Andrew Nashed.
