Ginkgo trees, are one of the oldest species of trees cultivated in China and are believed to be 150 to 200 million years old. The ginkgo trees grow in average soil and even in full sun. The tree can grow 100 – 120 feet. Ginkgo trees are very resistant to pollution and infection and hardly suffer any disease. Insects rarely attack these plants. Due to these reasons these trees are most tolerant even in urban conditions and are grown as shade trees.
Ginkgo or ginkgo biloba extracts is made from various parts of these trees. Chinease has used ginkgo biloba for the centuries for treating various ailments. Now it is most researched herb and is used by most of the countries as herbal medicine.
Working of Ginkgo Biloba:
Ginkgo leaves contains two groups of active components known as flavonoid glycosides and ginkgolides. These active ingredients helps in increasing blood flow to the brain and improving overall network of blood vessels, and consequently increases the inflow of oxygen and essential nutrients to brain and other important organs of the body and simultaneously helps controlling in allergic inflammation and asthma.
Benefits of Ginkgo Biloba:
The research on this herbal medicine continues for the last three decades and some of the benefits as evidenced by clinical studies have been summarized below.
Depression
Patients suffering from varying degrees of vascular insufficiency also noted an improvement in mood while taking ginkgo biloba extract. This has prompted a surge of interest in its use as a treatment for depression, especially in the elderly. Many people have found GBE to enhance other depression treatments and to often even prevent the need for pharmaceutical treatments in mild cases of depression. Those under the age of fifty may also benefit from ginkgo biloba's antidepressant effects. So far though, the greatest level of improvement has been noted with older patients.
Alzheimer's & Mental Function
As more than 300 studies demonstrate, ginkgo facilitates better blood flow through out the body, most notably the brain, where it both protects and promotes memory and mental function, even for people with Alzheimer's disease. It also offers a wealth of possibilities in the treatment of many other common ailments.
Alzheimer's
Since doctors are still not sure what causes Alzheimer's disease, we do not have a definite idea of how ginkgo works to stabilise, and in some cases, improve the quality of life for those suffering from this degenerative disease. Scientists have noted that Alzheimer's is marked by a major loss of nerve cells in the brain, particularly those in areas controlling memory and thinking. Since doctors have found antioxidants to help slow the destruction of nerves, it is not a stretch to see ginkgo's antioxidant properties helping in this area. The disease is also believed to have a connection to decreased blood flow to the brain. If so, ginkgo's vasodilating effects may be a big help in the treatment process. Either way, prominent doctors and scientists believe ginkgo to be the supplement of choice to help hold off and possibly treat Alzheimer's.
Antioxidant Properties
Although oxygen is essential for life, it can have adverse effects on your body. Unstable oxygen molecules can often be created during our body's normal break down and use of oxygen or can form in response to external factors and pollutants. These unstable molecules, called free radicals, can damage cells and structures within cells. If the genetic material in cells is affected and not repaired, it can replicate in new cells, contributing to cancer and other health problems. These free radicals may also weaken artery walls, allowing fatty deposits that can lead to hear disease. As an antioxidant, ginkgo biloba combats free radicals and repairs molecular damage. A great deal of research suggests that antioxidants such as GBE may play important roles in preventing or delaying heart disease, cancer and other ills. Antioxidants may even halt the damage to cells, thereby slowing the effects of aging.
Impotency
Another use for ginkgo biloba is in the treatment of impotency. The main cause of male impotence is poor circulation and impaired blood flow through the penis, which is often the result of atherosclerosis. Since ginkgo biloba increases blood flow, it's been found to help up to fifty percent of patients after six months of use.
Raynaud's disease
Raynaud's disease is believed to be caused by blood vessels that over react to the cold and spasm, reducing blood flow and there by depriving extremities of oxygen. Ginkgo biloba may help this condition by widening the small blood vessels, which would keep these spasms from completely blocking the blood flow.
Parkinson's Disease
The lack of dopamine is believed to produce the progressive stiffness, shaking and loss of muscle coordination typical in Parkinson's disease. Doctor's theorise that along with other treatments, Ginkgo biloba may help symptoms by increasing the brain's blood flow and thereby allowing more of the depleted dopamine to be circulated to the areas that need it most.
Other Conditions
Other uses for which ginkgo biloba extract is often recommended include depression, diabetes related nerve damage and poor circulation, allergies, vertigo, short-term memory loss, headache, atherosclerosis, tinnitus, cochlear deafness, macular degeneration, diabetic retinopathy, and PMS.
Strokes
Scientists continue to study the prevention and treatment benefits to stroke patients that are attributed to GBE. It's believed that by preventing blood clots from developing and increasing the blood flow to the brain, ginkgo biloba may help stop strokes from occurring. It's also believed that the herb inhibits free-radical damage of brain cells after a stroke.
Multiple sclerosis & Organ transplant
GBE also appears to have an anti-inflammatory action that may make it valuable in the future for conditions such as multiple sclerosis and organ transplants.
