Over a Decade of Proven Quality Testing & Production Method Work

Ginkgo biloba is the oldest living tree species on earth, dating back to the Paleozoic period, over 225 million years ago, and is often referred to as ‘the living fossil’. Individual specimens of the tree may live to be over 1,000 years old.

Today, standardized Ginkgo biloba (leaf) extract is one of the most respected botanical supplements used around the world. It is the subject of over 120 clinical studies, attesting to its therapeutic value in addressing: cerebral insufficiency, dementia, and circulatory (peripheral vascular) problems.

Unfortunately, due to its high production cost and value, Ginkgo extract is prone to adulteration or spiking in a number of ways; so it is also one of the most highly scrutinized extracts from regulatory and consumer viewpoints.

Since releasing its first report on Ginkgo adulteration in 2006 (in association with American Herbal Pharmacopoeia, AHP, and Eurofins Labs), ENI has taken a leading industry role in the development of methods to identify impurities and adulteration in Ginkgo extracts.

Today, our range of standard or customized Low Acid PureLeaf™ Ginkgo biloba extracts are the result of over a decade of testing and production method work.

When you use PureLeaf™ Ginkgo in your products, you can be assured that it will always pass the closest technical scrutiny and the satisfaction of your customers.
