Ginkgo biloba and the brain–myth vs. science

ginkgo-health-benefits-bullshitGinkgo biloba is actually an interesting plant because it has been relatively unchanged for nearly 270 million years. It is considered a living fossil, an informal term used for species like G. biloba that appear to be the same as a species otherwise only known from fossils and which has no close living relatives. The genus Ginkgo was fairly widely distributed until about 100 million years ago. It slowly disappeared from the fossil record until it was found only in one small part of China about 5 million years ago, where it is found today.  

The tree is native to China and is known to have been widely cultivated early in human history. It is used as a food source by various Asian cultures, with the Chinese eating the meaty gametophytes and the Japanese the whole seed.

Even if a manufacturer changes equipment or a process, without changing the the ingredients, it is required to file those changes with the FDA, and they may not proceed with the change. 

The same is not true of so called “natural health products.” In fact, according to a study published in BMC Medicinethe majority of herbal products on the market contain ingredients that are not listed on the product’s label. Furthermore, these companies (let’s call them Big Herbal) often substitute some of the ingredients with cheaper, untested alternatives and fillers.
