Breaking News About an Old Friend
"Ginkgo Biloba remains one of the most highly-touted nutritional supplements to encourage healthy mental clarity," imparts Klee Irwin. This herb-which comes from the world's oldest living tree species-has been used as far back as 2800 B.C.E. Ginkgo experienced a revival of sorts when research suggested that those who took it experienced enhanced memory and mood. For example, a recent Ginkgo study conducted at the University of Adelaide in Australia found that adults aged 55 to 79 years old showed improved longer-term memory during associated learning tasks (Burns, 2005).
Klee Irwin has learned that for years researchers have suspected that Ginkgo aids mental functioning because it helps encourage blood flow to neurons and other brain cells and tissues. However, recent studies suggest that Ginkgo may also help counteract the mind-numbing effects of stress. Initial studies with rats found that Ginkgo helped lessen cognitive deficits brought on by an injection of a stress hormone (Walesiuk, 2005). Meanwhile, a study with young human volunteers suggests that a single use of Ginkgo may ease stress-induced changes in blood pressure and may also influence cortisol release (Jezova, 2002). Plus, French researchers recently found that Ginkgo may affect the expression of specific genes implicated in the stress response (Soulie, 2002). In addition, Klee Irwin has discovered that new research highlights other "smart nutrients" that can be used as part of a healthy natural supplement program (see "Emerging Nutrients").
