Promising research suggests intravenous gingko may help patients recover from strokes
DALLAS, Feb. 1, 2024 —
… Ginkgo biloba is an herb extracted from the dried leaves and seeds of the gingko tree, one of the oldest living tree species and native to East Asia. It is widely used in traditional Chinese medicine and available as a supplement in the U.S. Compounded therapies of the active ingredients of gingko biloba, delivered by IV, are widely used to treat stroke in China because of its potential antioxidant properties that may protect nerve cells from damage. Ginkgo biloba is not approved by the U.S. Food and Drug Administration for any medicinal use, and there is not enough evidence to support any non-FDA approved use, according to the National Center for Complementary and Integrative Health, a division of the National Institutes of Health.

The researchers analyzed the cognitive recovery of 3,163 stroke survivors (average age of 63 years; 36% women) treated for mild to moderate ischemic stroke at 100 centers in China. Starting within 48 hours of the stroke, about half of the stroke survivors were randomly selected to receive daily, intravenous injections of 25 mg of GDLM for 14 days, while the other half received daily, intravenous placebo injections. Cognitive performance was assessed before treatment, at 14 days and at 90 days using the Montreal Cognitive Assessment scale (MoCA), a 30-point face-to-face screening test of cognitive performance often used with stroke survivors. At baseline — within 48 hours of the stroke and before beginning treatment, most patients’ cognitive status was moderately impaired, with an average score of 17 out of 30.

“The proportion of patients who reached a clinically significant level of improvement was 20% higher in the GDLM group, indicating that GDLM injections may improve cognitive function in patients with acute ischemic stroke,” Wang said. “Since the follow-up time in this study was only 90 days, the longer-term effect of GDLM injections requires longer-term research.”
“GDLM has shown a neuroprotective effect through multiple mechanisms, such as expanding brain blood vessels and improving brain cells tolerance to hypoxia (inadequate oxygen) and increasing cerebral blood flow. GDLM also has neuroprotective antioxidation, anti-inflammation and anti-apoptosis (cell death) properties,” Wang said. “Additionally, laboratory studies have previously indicated that GDLM may promote secretion of chemicals associated with avoiding neurodegenerative diseases, such as Parkinson’s disease and Alzheimer’s disease.”
“…Stroke patients should not take gingko biloba or other herbs or supplements without discussing it with their doctor and pharmacist….”

Also noteworthy from the article:
In early 2023, researchers from this study published the results of a multicenter trial in China indicating that people with ischemic stroke had better recovery from their overall stroke symptoms if they were treated with daily injections of ginkgo diterpene lactone meglumine (GDLM), a combination of the biologically active components of ginkgo biloba. The current investigation analyzed the cognitive recovery of participants in that study.
