Research Findings

  • Ginkgo biloba leaf tablet showed good efficacy in promoting episodic memory function in mild cognitive impairment patients.[1]
  • The leaf extract of Ginkgo biloba L. has been used for years to treat age-related memory-deficit problems, including Alzheimer's and dementia. Experimental and clinical studies have revealed its beneficial effects on a wide range of pathological conditions including hepatoprotective, photoprotective effects, DNA repair mechanism, antioxidant and anti-inflammatory activities. Recent studies have also suggested that leaf extract of G. biloba L. may exert beneficial effects on cancer.[2]
  • The extract from Ginkgo biloba leaf can lower blood lipid levels and urinic protein in children with nephritic syndrome and improve their clinical syptoms and the renal function. [3]
  • The Ginkgo leaf extract has been reported to have neuroprotective, anticancer, cardioprotective, stress alleviating, and memory enhancing effects and possible effects on tinnitus, geriatric complaints, and psychiatric disorders.[4]
  • Antioxidant Ginkgo biloba leaf extract exhibited a mild effect on psychological state and a trend of improving glycemic control in patients with type 2 diabetes mellitus.[5]
  • Ginkgo biloba leave extract has been prescribed to treat CNS disorders such as Alzheimer's disease and cognitive deficits.[6]
  • Numerous preclinical studies have shown the neuroprotective effects of standardized extract from the leaves of the Ginkgo biloba tree and support the notion that it may be effective in the treatment and prevention of neurodegenerative disorders such as Alzheimer's disease.  [7]
  • The potential use of Ginkgo biloba extract 761 has been proposed for the treatment of psychiatric disorders such as anxiety and depression. [9]
  • Ginkgo biloba leaf extract  (Ginaton) could improve cerebral oxygen supply, promote superoxide dismutase  activity to inhibit production of free radicals in patients undergoing cardiopulmonary bypass. [10]
  • Ginkgo biloba L. can reduce the severity of premenstrual symptoms.[11]
  • Extract from Ginkgo biloba leaves has been reported to have antioxidatant properties, to modify vasomotor function, to reduce adhesion of blood cells to endothelium, to inhibit activation of platelets and smooth muscle cells, to affect ion channels, and to alter signal transduction.[12]
  • In clinical trials of different working-groups, effects of Ginkgo biloba on the cognitive performance, global function, and activities of the daily living have been found.[13]
  • The combined therapy with hypha cordyceps and ginkgo leaf tablet could effectively improve micro-inflammation reaction exists popularly in patients undergoing maintenance hemodialysis. [14]
  • Ginkgo biloba appears as a useful and sensible supplementary medication to treat Alzheimer's disease. [15]
  • Ginkgo leaf extract could decrease the plasma level of vascular endothelial function, raise the plasma nitric oxide  level and improve the endothelium dependent vascular dilating function in diabetic nephropathy  patients.[16]
  • Clinical studies have shown that ginkgo extracts exhibit therapeutic activity in a variety of disorders including Alzheimer's disease, failing memory, age-related dementias, poor cerebral and ocular blood flow, congestive symptoms of premenstrual syndrome, and the prevention of altitude sickness.[17]
  • Favorable results have been obtained in double-blind, placebo-controlled, comparative trials of patients with memory disorders, obstructive arteriosclerosis, and dementia.[18]
  • Ginkgo Leaf Tablet can decrease serum normal T cell expressed and secreted level in patients with diabetes mellitus type 2. [19]
  • Holistic fresh leaf extract of Ginkgo biloba is a safe, effective, and, at least, adjuvant treatment option for patients with mild cognitive impairments.[20]
  • Folium Ginkgo extract displays the effects of nerve tissue protection and hypoxia-ischemic brain injury alleviation.[21]


Contraindicated in patients with exterior pathogenic factors

Report on adverse effect

Ginkgo should be used with caution during pregnancy, particularly around labour where its anti-platelet properties could prolong bleeding time.[8]

Headaches, gastrointestinal disturbances, and allergic skin reactions are possible adverse effects [22]
