Tinnitus is a symptom frequently encountered by ear, nose, and throat practitioners. A causal treatment is rarely possible, and drug and nondrug treatment options are limited. One of the frequently prescribed treatments is Ginkgo biloba extract. Therefore, randomized, placebo-controlled clinical trials of Ginkgo biloba extract preparations were searched for and reviewed systematically. There is...

Ginkgo biloba (Ginkgoaceae), originating from China, now distributes all over the world. Wide application of Ginkgo biloba extracts is determined by the main active substances, flavonoids and terpenoids, which indicates its extracts suitable to be used as an effective corrosion inhibitor. The extracts of Ginkgo biloba leave have been investigated on the corrosion inhibition of Q235A steel with ...

The objective of the study was to evaluate the antidiabetic activity of Ginkgo biloba and to probe into its mechanism of action. Methods. Albino wistar rats with streptozotocin induced diabetes were divided into 4 groups of 10 each. Gum acacia, troglitazone 36 mg/kg, Ginkgo biloba 50 mg/kg and 100 mg/kg, were administered to group I (control), group II (standard), group III and group IV respect...

Ginkgo biloba is the most popular phytotherapic agent used worldwide for treatment of several human disorders. However, the mechanisms involved in the protective actions of Ginkgo biloba on cardiovascular diseases remain poorly elucidated. Taking into account recent studies showing beneficial actions of cholinergic signaling in the heart and the cholinergic hypothesis of Ginkgo biloba-mediated ...

BACKGROUND The benefit of Ginkgo biloba for the treatment of dementia remains controversial. The aim of this study was to evaluate the efficacy and safety of Ginkgo biloba in patients with dementia in whom administration effects were reported using meta-analysis. METHODS We searched MEDLINE, Embase, the Cochrane databases, and Ichushi for controlled trials of Ginkgo biloba for the treatment d...

One of the most remarkable things about the ancient tree, Ginkgo biloba L., is its resistance to pests and disease (1). Although some effort has been made in the past to find substances in parts of G. biloba L. which might account for this resistance, no success seems to have attended these efforts (2-4). A systematic examination of various parts of G. biloba L. has been undertaken in order to ...

BACKGROUND There is some evidence to suggest that ginseng and Ginkgo biloba can improve cognitive performance, however, very little is known about the mechanisms associated with such improvement. Here, we tested whether cardiovascular reactivity to a task is associated with cognitive improvement. METHODOLOGY/PRINCIPAL FINDINGS Using a double-blind, placebo controlled, crossover design, partic...

Photosynthetic pigments, biochemical activities and chlorophyll a fluorescence kinetics were investigated to survey the photosynthetic characteristics of Ginkgo biloba L. during leaf growth. The content of total chlorophyll increased rapidly while the content of carotenoids changed a little. The content of ATP, the activity of O2 evolution of chloroplasts, the electron transport activities, the...

OBJECTIVES Doubt over the cost-effectiveness of the cholinesterase inhibitors in dementia has renewed interest in alternative treatments such as Ginkgo biloba. We aimed to determine the effectiveness and the safety profile of Ginkgo biloba for treating early stage dementia in a community setting. METHODS We conducted a community-based, pragmatic, randomised, double-blind, parallel-group trial...
