Habitat: Native to China and Japan; cultivated in Indian gardens as an ornamental.
English: Maidenhair tree called Living Fossils (in India), Kew tree.Action: Antagonizes bronchospasm, used as a circulatory stimulant, peripheral vasodilator.
Key application: Standardized dry extract—for symptomatic treatment of disturbed performance in organic brain syndrome within the regimen ofa therapeutic concept in cases of dementia syndromes— memory deficits, disturbance in concentration, depressive emotional conditions, dizziness, tinnitus and headache. (German Commission E, ESCOP, WHO.) As vasoactive and platelet aggregation inhibitor.(The British Herbal Pharmacopoeia.) (For pharmocological studies in humans and clinical studies, see ESCOP.)The majority of pharmacological studies and clinical trials have been conduced using a standardized extract which contains 24% flavonoid glyco- sides (Ginko flavone glycosides) and 6% terpenoids (ginkgolides and bilob- alide).The extract increases tolerance to hypoxia and exhibits anti-ischaemic effect. It simultaneously improves the fluidity of blood, decreases platelet adhesion, decreases platelet and erythro- cyte aggregation and reduces plasma and blood viscosity. The extract protects erythrocytes from haemolysis. The extract also decreases the permeability of capillaries and protects the cell membrane by trapping deleterious free radicals.The extract also increased cerebral blood flow in about 70% patients evaluated (patients between 30-50 year age had 20% increase from the base line, compared with 70% in those 50- to 70- year-olds).A reversal of sexual dysfunction with concurrent use of ginkgo with antidepressant drugs has been reported. (Am J Psychiatry, 2000 157(5), 836837.)The National Centre for Complementary and Alternative Medicine, USA, is conducting a 5-year study of 3000 people aged 75 and older to determine if ginkgo, 240 mg daily, prevents dementia or Alzheimer's disease.... ginkgo bilobaKeynotes: brain and lungs.
Constituents: terpenes, tannins, lignans, flavonoids, and gingkolide B which is a platelet activating factor (PAF).
Action: nutritive, tuberculostatic. A compound (BN 52021) from the tree antagonises bronchospasm and tends to resolve breathing difficulties. Circulatory stimulant. Increases brain blood flow, Peripheral vasodilator, Energy enhancer. (JAM, Vol 6, No 2)

Tea (leaves). 1 heaped teaspoon to each cup of water gently simmered 5 minutes. Dose: half-1 cup. Tablets/capsules. 250mg. Maintenance dose: one tablet or capsule increasing to two in acute cases. Chinese Medicine. “Seeds moisten the lungs, stop coughing, and strengthen the body.”
“I have seen a reduction in severity and frequency of asthma attacks and a marked reduction in use of brocho-dilating drugs by the use of Ginkgo.” (Brown D., Phytotherapy Review and Commentary, Townsend Letter to Doctors, October 1990 pp648-9)
German medicine. No drug interactions and very low levels of side-effects. Important remedy to the German Health Service at a cost of 286 million DM in 1989. (Kleijnen J. & Knipschild P. The Lancet 1992, 340, Nov 7)
Tincture. 2 tsp a.m. and p.m. ... ginkgo
