Use Green Tea Extract and Curcumin to Ward Off Oral Cancer

Bowls of green tea extract and curcumin

Early signs of oral cancer can include white patches, sores and lumps inside the mouth, biomarkers known collectively as oral potentially malignant disorders (OPMD). To see if two natural chemopreventive agents—green tea extract and curcumin—could reverse these conditions, researchers in India tested 60 people with OPMD, splitting them into three groups. One group was given 400 milligrams (mg) of green tea extract in a capsule, as well as a gel; a second group was given 475 mg of curcumin; and the third received a combination of the first two treatments. After 12 weeks, researchers found that the supplementation had significantly reduced OPMD biomarkers in all three groups, with particularly strong results in the combination group, suggesting a synergistic effect.

Healthy Ways To Spend Time At Home
Global Brief: Natural Thinking Spending Time in Nature Increases Cognitive Performance
More of our time is spent indoors than ever before. One of the ways by which nature may improve cognitive function (i.e. the acquisition of and goal-oriented use of knowledge) is by improving memory formation and recall, specifically that of short-term or working memory, and goal-oriented or directed attention; the kind that requires focused effort. By comparing and contrasting 13 studies, a team of researchers has shed light on this complex interaction in research published in Frontiers in Psychology. The studies used the backwards digit span task, which requires participants to invert a series of numbers and repeat them back. All demonstrated significantly improved cognition in nature as compared to urban environments. The benefits of studies like this are two-fold: not only are we learning more about how the brain interacts with its environment, but also how to leverage this interaction to lead healthier, more productive and happier lives.
