Ginkgo Biloba is a special Nootropics ingredient that has properties to enhance the cognitive abilities of a person. It is known to have a positive effect on the thinking process, reasoning, memory retention, and recall. Hence, this has been considered safe and is added to most Nootropic supplements. But if it is mixed with other drugs or ingredients there can be severe reactions. So, the intake of Ginkgo has to be done in the correct combination as well as the correct dosage.
