Being one of the oldest living tree species, ginkgo trees ranged throughout temperate regions of the world some 50 million years ago. Nevertheless, one species, Ginkgo biloba, native to southeast China, survived the millennia while all others went extinct. Ginkgo has become one of the well-researched herbs in the world.
Ginkgo seeds have been used in traditional Chinese medicine for thousands of years. Its ability to treat circulatory disorders and enhancing memory has been supported from scientific studies throughout the years.
However, the most extensively used and studied in medical purposes is Ginkgo's leave. Ginkgo leaves are not frequently used in their crude state. Rather, they are used in the form of a concentrated, standardized Ginkgo Biloba Extract (GBE). In the last 30 years, more that 300 studies have given clinical evidence that ginkgo prevents and benefits many problems throughout the entire body.
Ginkgo is used extensively as a brain tonic that enhances memory because of its positive effects on the vascular system. It is also used to treat vertigo, tinnitus (ringing in the ears) and a variety of neurological disorders and circulation problems. Ginkgo may help to counteract the effects of aging, including mental fatigue and lack of energy.
Ginkgo can also be used to prevent and overcome problems related to heart disease. Standardized GBE inhibits platelet activity factor (PAF), which is a common allergen in the body. Physical stress, and poor quality food can over-stimulate PAF production, I other words, blood clotting. Excessive PAF can cause cardiovascular disease, brain damage, hearing disorders, and other immune and inflammatory diseases.
Ginkgo can also act as a powerful antioxidant that can protect the eyes, cardiovascular system and central nervous system. Ginkgo may also help control the transformation of cholesterol to plaque associated with the hardening of arteries, and can relax constricted blood vessels.
The herb has also been used in treatment of other circulation-related disorders such as diabetic peripheral vascular disease, Raynaud's syndrome, hemorrhoids and varicose veins. It can also aid in the treatment of insufficient circulation and complications from stroke and skull injuries.
Ginkgo can also be beneficial in treating eye and ear disorders. Studies have confirmed that ginkgo increases blood flow to the retina, and hence can slow retinal deterioration resulting in an increase of visual acuity. In clinical tests, ginkgo has improved hearing loss in the elderly. It also helps improve circulation in relieving cold hands and feet, swelling in the limbs and chronic arterial blockage.
Ginkgo is being investigated as a potential treatment to prevent the rejection of transplanted organs, as a treatment for asthma, and for toxic shock syndrome.
GBE is considered to be safe with very rare side effects, but there were still few cases of gastrointestinal upset, headaches, skin reactions, and dizziness being reported. Because of its ability to decrease platelet aggregation (stickiness), there is some concern that it may increase risk of intracranial (brain) hemorrhage. So, if you are treated with blood thinning or other medications, you should seek advice from your doctors before using ginkgo. It is also advised by experts that ginkgo should not be used by pregnant and breastfeeding women, and should be discontinued at least 36 hours prior to surgery due to the risk of bleeding complications.

The heart is an important organ. It must pump blood each and every day for you, tirelessly, without fail and without rest to ensure that you remain alive.

It may be that anger and hostility are far more hurtful-especially when considering the heart. A recent study at the National Institute for Aging has found that hostile people-especially those who are manipulative and aggressive-may be paying a price in terms of heart health.
A cardiac diet is suggested by dieticians to patients who are at a higher risk of suffering from high blood pressure, heart problems and obesity. The diet is planned in way to make the heart healthy and to prevent any risk to heart. One of the major enemies of heart is bad cholesterol and unhealthy fats. Certain fat products are made from mono-saturated fat which helps in decreasing the level of bad cholesterol in human body and it is allowed in a cardiac diet.
High cholesterol is invisible dangers which can cause severe damage to human body and to measure high cholesterol doctors examine the level of HDL, LDL and triglyceride levels in body. The bad cholesterol or the LDL cholesterol accumulates in the inner walls of arteries and it can block the passage whereas the HDL cholesterol is helpful in preventing blockages.
