Americans had spent around dollar fourteen billion on vitamins
, herbal remedies, dietary supplements and minerals in the year 1998. The Chinese herbal medicine made from the leaves of the ginkgo biloba plant sold millions of their products in America and claimed that their products enhance metal performance. They also say that their product improves memory and concentration. Still the scientific evidence is not as clear whether it can boost mental powers or not.
For example, Pharmaton Natural Health Products sell supplements called Ginkoba. They say that their supplement can improve memory and concentration. It also gives a detailed scientific proof which highlights seventeen studies published in scientific journals along with the product. Most of these scientific studies said that it works on older people while six studies said that it is effective on young and healthy people.
Then a research was carried out under which people who were under the age 40 were given the doses of the medicine and then their mental performance was tested. Some studies were carried out to test short term memory improvements while some studies were carried out to test overall memory sharpness. While some test also measured brain wave patterns to find out the effect of ginkgo biloba on brain memory. It is still unclear whether it can improve memory loss which is caused due to Alzheimers disease. Still more studies are needed to determine the possible benefits of ginkgo biloba and for now it is considered safe if taken under the advice of a doctor or a health care professional. There are side effects of ginkgo biloba mainly bleeding which should be taken into consideration before starting the medicine.
