Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Ginkgo biloba has been studied for its potential role in managing Attention Deficit Disorder (ADD), particularly Attention Deficit Hyperactivity Disorder (ADHD) in children and adults. The rationale for its use is primarily scientific rather than traditional, as ginkgo has not been a classic herbal remedy for attention disorders in historical medical systems. The interest is driven by ginkgo’s pharmacological effects—mainly its antioxidant and neuroprotective properties, as well as its influence on neurotransmitter systems, including dopamine and norepinephrine, which are implicated in attention regulation.

A handful of small clinical trials and open-label studies have investigated ginkgo biloba as either a monotherapy or adjunct to stimulant medications in ADHD. The evidence from these studies is mixed and generally of low quality, with some suggesting modest improvements in attention, hyperactivity, or executive function, while others show no significant effect compared to placebo. A 2014 randomized controlled trial found ginkgo to be less effective than methylphenidate, a standard ADHD medication, but reported fewer side effects. Meta-analyses and systematic reviews typically conclude that there is insufficient high-quality evidence to recommend ginkgo biloba for ADD/ADHD, and that more rigorous research is needed.

In summary, while there is some scientific investigation into ginkgo biloba’s role in attention disorders, the overall evidence is weak, inconsistent, and not sufficient to support its routine use for ADD/ADHD. It should not be considered a substitute for established treatments.
