The Ginko Biloba tree is known as a living fossil, dating back over 250 million years. Groves in the Tian Mu Shan Reserve in the Zhejiang province of Eastern China are over 1,000 years old, believed to have been tended to throughout their time by Chinese monks. In the Shandong province of China, a specimen has been located that is over 3,000 years old.
The ability for these trees to survive for such great lengths of time demonstrates a natural resistance to insects and disease. In fact, they have been called the most “urban tolerant” of any tree, flourishing in environments where other trees die out.
The Chinese have been using Ginko Biloba for hundreds of years in healing medicine. Further scientific studies have confirmed its usefulness in pharmaceutical use, and it since has become popular as an herbal treatment for dementia, tinnitus, and as an anti-vertigo treatment.
How Ginko acts Upon the Human Body
Ginko acts as a blood thinner and creates dilation of the blood vessels, therefore improving circulation. The increase in cerebral blood flow is the primary factor leading to the belief Ginko prevents degeneration of the brain cells.
Because of its blood thinning qualities, Ginko also blocks many effects of blood clotting and platelet aggregation that are associated with cardiovascular, respiratory, renal, and central nervous system disorders.
It also acts as a powerful antioxidant, preventing cells from becoming damaged by free radicals, which can also help to slow the degenerative process.
The effects of Ginko have been shown to provide an immediate boost to concentration levels, which peak around two and a half hours following its intake. This can help assist anyone who requires additional focus such as athletes, business people, and home business owners as they go about their daily tasks.
The Effects of Ginko on Memory Function
Several studies have been conducted that reveal the effects of Ginko to enhance or maintain memory function. In 2006, a study published in the European Journal of Neurology detailed an Italian study of the herb, which concluded its effects in the treatment of mild to moderate Alzheimer’s were just as effective as the pharmaceutical drug donepezil, sold under the brand name Aricept.
A three year study of 118 people who were 85 years of age or older, with no memory problems at the beginning of the study, revealed that those who followed the dosage instructions and were reliable in taking Ginko throughout the course of the study had a 68 percent lower chance of experiencing cognitive decline than those who took a placebo.
Side Effects of Ginko
During the study, seven of the participants taking Ginko suffered strokes or mini-strokes, while none of the participants who were taking the placebo had strokes. Those strokes, though, were due to blood clots rather than excessive bleeding, leading to questions as to whether they were at all related to Ginko use. In all cases, the strokes were not severe.
Other side effects of Ginko can include headache, nausea, dizziness, diarrhea, stomach upset, and allergic reactions. Because it acts as a blood thinner, it should not be used by anyone who already has trouble with proper blood clotting function or any other bleeding disorder. It should not be taken by those on MAOI inhibitors or by pregnant or lactating women, and its use should be discontinued prior to undergoing any dental or surgical procedure.
