Circulation ginkgo

To improve blood circulation. Ginkgo Ginkgo bilobd) extract is irsed, which is made of the leaves of the plant. The extract contains known qirantities of two groups of active components (ginkgolids and bilobahde). It is imknown which of these two is responsible for the physiological effects. Therefore, Ginkgo extract is a quantified product. 

These days everybody is talking about ginkgo biloba, a concentrate made from the extracts of the leaves of a tree that has been around for over two hundred million years. The species was brought from China to Europe in the eighteenth century, and it became a popular decorative tree. It also serves a medicinal purpose. The leaves are picked, dried, and ground to a powder. This powder is extracted with an acetone-water mixture, and then these solvents are evaporated off. The residue that remains is compacted into a variety of pills. Several components of this residue may have beneficial effects in particular, they may improve circulation to the brain. Clinical studies have confirmed that ginkgo extracts dilate blood vessels and improve blood flow in arteries and capillaries. Two classes of... 

Traditional Chinese physicians used ginkgo leaves to treat asthma and chilblains. Today, G. biloba is used to improve both blood flow to the brain and peripheral circulation (see Chapter 36). 

Ginkgo biloba has become popular bccau.se of its putative abilities to increase peripheral and cerebral circulation. ITic herb is called an adaptogen, a drug that helps persons handle stress. In the periphery, the hertj has been compared to pentoxifylline. If the properties arc true, the herb could be used for intermittent claudication. If cerebral blood flow can be increased with Ginkgo biloba. the herb might be useful... 

Ginkgo (Ginkgo hiloha) has shown activity in increasing peripheral and cerebral circulation. Recent studies published in the Journal of the American Medical Association (JAMA) showed a protective effect for ginkgo for people with Alzheimer s disease. One Japanese study (Kobayashi et al, 1993) claims that a 70 percent alcohol extract of this herb applied topically stimulated hair growth in shaved laboratory mice. No other studies have found this activity, but it does suggest a possible new use for ginkgo.

Ginkgo biloba (GB) is sold as a dietary supplement in the United States. It is purported to improve blood flow to the brain and to improve peripheral circulation. It is promoted mainly to sharpen mental focus in otherwise healthy adults as well as in those with dementia. Other conditions for which it is currently used are diabetes-related circulatory disorders, impotence, and vertigo. 

As a general precaution, ginkgo biloba may increase the risk of excessive bleeding, especially for people with blood circulation disorders and for those taking ibuprofen, aspirin, or other anti-coagulants. 

Cerebral insufficiency refers to describe the people with age-related decline in mental function and decrease blood flow to the brain cause by clogged arteries. Platelet activating factor (PAF) is an inflammatory mediator, plays an important role in allergy, inflammatory processes, coronary, and cerebral vasoconstriction [178]. The production and release of PAF in the brain under various pathological conditions, including oxidant stress-induced ischemic injury [179]. The efficiency of EGb-761 on cerebral circulation and metabolism has been demonstrated in various models of cerebrovascular insufficiency and showed beneficial effect like cerebral edema in rats intoxicated with triethyltin chloride (TET) [180]. Moreover, oral or intravenous administrations EGb decrease cerebral edema development in gerbils [181]. In an animal study [182], EGb-761 and an extract of local ginkgo... 

More than 300 papers have been published on the pharmacological properties of this extract [23]. Experimentally documented activity includes increased tolerance to hypoxia in brain tissue, improved learning capacity and memory, inhibition of platelet activator factor (PAF) [24], improved cerebral and peripheral circulation, neuroprotective effects [25], and reduction of retinal edema. Although all the constituents of the ginkgo extract are considered to contribute to the therapeutic effects, the ginkgo flavonoids are assumed to play an important role that is due to their free radical scavenging capacity.
