4. Gingko Biloba
Ginkgo Biloba is often used for memory disorders including Alzheimer’s Disease. It is also used for conditions that seem to be due to reduced blood flow in the brain, especially in older people. These conditions include memory loss, headache, ringing in the ears, vertigo, difficulty concentrating, mood disturbances, and hearing disorders. Some people use it for other problems related to poor blood flow in the body, including leg pain when walking. Ginkgo leaf is also used for thinking disorders related to Lyme disease and depression. Some people use ginkgo to treat sexual performance problems. Human clinical trials show that Gingko helps to slow down or restore cognitive dysfunction in those who have vascular dementia or Alzheimer's Disease.
