Ginkgolic acids Calculate the concentration, in μg per g, of each ginkgolic acid in the portion of Powdered Extract taken by the formula: Calculate the total amount of ginkgolic acids by adding the individual contents: the limit is Calculate the total percentage of flavonol glycosides by adding the 5 μg per g. individual percentages calculated. Packaging and storage Preserve in tight, light-resistant containers, protected from moisture, and store at controlled room temperature. Labeling The label states the Latin binomial and, following the official name, the part of the plant from which the article was prepared. The label also indicates the content of flavonol glycosides and of terpene lactones, the extracting solvent used for preparation, and the ratio of the starting crude plant material to the Powdered Extract. Microbial enumeration It meets the requirements of the tests for absence of Salmonella species and Escherichia coli. The total aerobic bacterial count does not exceed 104 cfu per g, and the total combined molds and yeasts count does not exceed 103 cfu per g. Loss on drying Dry about 1.0 g of Powdered Extract, accurately weighed, at 105 for 2 hours: it loses not more than 5.0% of its weight. Pesticide residues meets the requirements.
Ginkgo biloba has been used medicinally for thousands of years. Today, it is one of the top-selling herbs in the United States.
Ginkgo is used for the treatment of numerous conditions, many of which are under scientific investigation. Available evidence demonstrates ginkgo's efficacy in the management of intermittent claudication, Alzheimer's/multi-infarct dementia, and "cerebral insufficiency" (a syndrome thought to be secondary to atherosclerotic disease, characterized by impaired concentration, confusion, decreased physical performance, fatigue, headache, dizziness, depression, and anxiety).
Although not definitive, there is promising early evidence favoring the use of ginkgo for memory enhancement in healthy subjects, altitude (mountain) sickness, symptoms of premenstrual syndrome (PMS), age-related eye disorders, and the reduction of chemotherapy-induced end-organ vascular damage.
The herb is generally well tolerated, but due to multiple case reports of bleeding, it should be used cautiously in patients on anticoagulant therapy and those with known blood clotting disorders, or prior to some surgical or dental procedures.
Health Benefits Of Ginkgo Biloba
Proven Uses of Ginkgo Biloba
The following list is some of the uses of Ginkgo biloba that have proven, scientific backing: Claudication (pain in the legs from clogged arteries): Some people with a condition known as claudication have pain in their legs while resting or after exercise. Ginkgo biloba has been shown to help this type of pain. Ginkgo biloba, however, is not as effective as physical therapy for this condition.
Dementia: People with early stage Alzheimer's disease and multi-infarct dementia may benefit from taking Ginkgo biloba. The scientific research shows that Ginkgo biloba may be as effective as some of the prescription medications for these conditions.
Ginkgo Biloba for Cerebral Insufficiency
While the research isn't as solid as the conditions above, using Ginkgo biloba for a condition called cerebral insufficiency holds promise. Cerebral insufficiency is a syndrome more commonly diagnosed in Europe that involves poor concentration, confusion, forgetfulness, headaches, fatigue, depression and anxiety. Some researchers believe that this condition is caused by a decrease in the amount of blood available to the brain because of clogged blood vessels.
