Gotu kola is a plant native to South Africa, India, China, Sri Lanka, Japan and Indonesia. According to the University of Maryland Medical Center, people have used the plant for thousands of years to improve focus and memory and to reduce mental fatigue. It is most commonly taken as a tea but can also be found in capsule form. People with diabetes should not take gotu kola, because it may raise blood sugar levels. Also, the herb has a diuretic effect, which may deplete the body of fluids and electrolytes.

Although taking rosemary as a tea or in capsule form is considered safe, large amounts of the herb can cause stomach discomfort.
Ginkgo biloba leaves come from long-living trees found in China, and supplements containing extracts from these leaves have become very popular in the Western world.

It is available in both capsule and liquid form. Ginkgo biloba may increase the effect of blood thinners and should not be taken with medications that increase the risk of seizures, such as antidepressants.
