Other Names: Ginkgo biloba
Composition: Extracts from ginkgo leaves have flavonols, terpenes, and glycosides.
Description and History: The ginkgo tree is native to China and has been used medicinally since 2800 BC. Its fruit/seeds are also consumed in many traditional dishes.
Cross-Reference List: Headache
Headache: For symptomatic relief, ginkgo has been evaluated in a 60mg dose, as-needed. Results indicated that it reduced total duration of the headache by 1/3 as compared to a control group.
ADHD: Anyone connected with ADHD knows that the demand for non-pharmaceutical solutions and supportive therapies is high. Ginkgo may be a reasonable option. Compared with Ritalin at 20-30mg/day plus nothing else or plus ginkgo at 80-120 mg/day for 6 weeks, ginkgo made a significant difference for teen volunteers. A greater symptom reduction took place in the ginkgo group on both teacher-reported measures and objective measures evaluating focus and attention. (Shakibaei et al, 2015)
Metabolic Syndrome: A specific collection of risk factors makes heart disease and type 2 diabetes much more likely, and we call this metabolic syndrome. A recent approach to combating these factors is through anti-inflammatory avenues. Over a 2 month intervention trial, ginkgo supplementation resulted in the significant reduction of inflammatory and oxidative stress as compared to the control group, as well as a reduction in nano plaque formation. (Siegel et al, 2014)
Stroke: After a stroke, the brain is particularly vulnerable and significant damage can occur. In 2013, a total of 102 patients who had experienced acute ischemic stroke volunteered, and 52 received ginkgo while the rest were given a control. The follow-up 4 months later showed the ginkgo group with favorable evaluation scores. (Oskouei et al 2013) Ginkgo supplementation can be considered as part of a post-stroke protective protocol.
Contraindications: None known.
Interactions: None known.
Preparations: Ginkgo is administered orally through a wide range of preparations. The most common type of preparation is a capsule, tablet, or tincture, but it can be used to produce a cognitive enhancing syrup, truffle, or other preparation if desired.
Dose: The total daily dose for an otherwise healthy adult is 240mg per day, which can be divided by weight and age into a child’s dose using the dosing guidance provided in the pediatric module. There is no topical dose as the herb is typically consumed internally for cognitive functioning.
