Giloba is one of the oldest trees on the earth, having lived for over 150 million years. This is used as an herbal medicine for centuries. Giloba is generally accepted as a remedy for minor deficits in brain function, such as those that occur with advancing age. It is used to improve concentration and combat short-term memory loss due to dogged arteries in the brain, and to treat dizziness, ringing in the ears, headache and emotional hypersensitivity accompanied by anxiety.
