Ginkgo Doesn't Improve Memory Or Cognitive Skills

JumperCable writes "Ginkgo biloba has failed — again — to live up to its reputation for boosting memory and brain function. Just over a year after a study showed that the herb doesn't prevent dementia and Alzheimer's disease, a new study from the same team of researchers has found no evidence that ginkgo reduces the normal cognitive decline that comes with aging. In the new study, the largest of its kind to date, DeKosky and his colleagues followed more than 3,000 people between the ages of 72 and 96 for an average of six years. Half of the participants took two 120-milligram capsules of ginkgo a day during the study period, and the other half took a placebo. The people who took ginkgo showed no differences in attention, memory, and other cognitive measures compared to those who took the placebo, according to the study, which was published in this week's Journal of the American Medical Association."

memory no... blood flow very much so

Aspirin or Ginko?

Better concentration (some subjects thinking that that is one of the memory functions) could be a side effect of them not having headaches due to hypertension. Sample set yadi yada and so on.... statistics and damned lies.

Well, that or you just assume that's the effect it will have on you, and so you behave accordingly.

But, hey, who am I to argue with a placebo effect that works for you?

The "These claims have not been evaluated by the FDA" and its close friend "This product is not intended to diagnose, treat, cure, or prevent any disease." are generally a signal that the product is sold as a "dietary supplement" or "nutritional supplement".

Thanks to DSHEA, the FDA legally can't do jack about it unless they have direct evidence of a given product causing serious harm(and their budget for going on epidemiological expeditions for that sort of thing isn't much to write home about).

Whether you consider this a shining beacon of freedom, or an ignoble nest of quacks, it seems likely to remain so for the foreseeable future.

Supplements industry group replies with BS

[noidentity]

I love the bullshit reply from the supplements industry group:

A supplements industry group, Council for Responsible Nutrition, said other studies suggest the herbal supplement can be effective in improving cognitive function.

"In an area where there are few other safe, affordable options, I would hate to see this study send the wrong message to consumers," Douglas MacKay, CRN vice president said in an email. "I would continue to recommend Ginkgo biloba to older adults as a safe, effective option for supporting cognitive health."

Cue the "but it worked in my case" replies...
