Ginkgo biloba Extract (Egb761) is one of the most frequently prescribed herbal remedies both in Europe and worldwide with over 400 published studies primarily in the management of cerebrovascular and peripheral circulatory disorders.
Spearheaded by Dr Wilmar Schwabe GmbH of Germany, twenty years of research resulted in a standardized, concentrated extract of Ginkgo leaves known internationally as Egb761 (Natures Way Ginkgold in New Zealand). The twenty seven step extraction process requires approx. 23 kgs of ginkgo leaves to make 2 kgs of the extract and takes up to two weeks to complete.
Critical Manufacturing Process
Most critical to the extraction process and final product is the standardization of two groups of active components: ginkgo flavone glycosides and terpene lactones. The 24% ginkgo flavone glycosides content of Egb761 constitutes a carefully measured balance of three bioflavonoids. These are primarily responsible for Egb761's antioxidant activity and ability to inhibit platelet aggregation.
Unique to Egb761 are the 6% terpene lactones in the final extract. These have been shown to improve circulation and provide platelet-activating factor (PAF) antagonistic properties. Some of them have also exhibited neuroprotective properties and may stimulate regeneration of damaged nerve cells.
The primary uses for Egb761 worldwide include cerebrovascular insufficiency and intermittent claudication. Egb761 is also licensed in Germany for the supportive treatment of sensorineural hearing loss, tinnitus, head injury, macular degeneration and impotence.
Encompassed under the designation "cerebrovascular insufficiency" are dementia, resistant depression, vertigo and tinnitus. Using daily doses of 120 to 240 mg of Egb761, research has indicated an improvement in the symptoms within six to twelve weeks.
The potential for Egb761 in the area of dementia of arteriosclerotic origin and also for persons recovering from strokes is notable. Egb761 is a common prescription for depressed geriatric patients who are not responding to standard drug therapy. Current research is also showing promising results using Egb761 in the early stages of senile dementia of the Alzheimer's type.
Egb761 is used for persons with intermittent claudication (leg pain with walking) using doses of 120 to 160 mg daily for three to six months. Egb761 has led to an increase in pain-free walking distance and increased blood flow to the affected limbs.
For preventive use and for circulation problems to the extremities, Egb761 is recommended at a daily dose of 120 mg in divided doses. Daily dosages of 240 mg are required for cases of cerebrovascular insufficiency, early stage Alzheimer's disease, resistant depression and impotence. An initial six to eight week period is recommended to ascertain the effectiveness.
Excellent Safety Profile
Side effects are very rare. Some people with cerebrovascular insufficiency may experience a mild, transient headache for the first one or two days of use due to increase in blood flow.
Note: Only the unique Ginkgo biloba extract Ginkgold Egb761 has been proven in the above research. Other Ginkgo products may not yield the same results.
