Trevor Ponder Human Memory

Many herbs can safely strengthen and improve the body’s systems, including the brain and memory. Most herbs have few side effects, but read the labels, as some should not be taken if certain health risks are present. Some herbs help to enhance memory by improving the flow of blood through the brain, while others work to ensure the brain has plenty of oxygen. The brain needs 20% of the oxygen that is consumed by the entire body in order to keep mental processes running smoothly and to prevent poor concentration and vertigo. Some boost energy, our immune system and metabolism. They accomplish this by fighting free radicals, which are substances that are also known to speed up the development of cancer and heart disease. Here are a few that are commonly recommended (Rai, Shovlin & Wesnes, 1991; Perry et al., 1998):

•    Huperzine A – This chemical made from the plant Huperzia serrata has been shown in studies to improve memory in both vascular and Alzheimer’s dementia.

•    Lemon Balm – Improves cognitive function.

•    Ginseng – Improves memory and mental alertness.

•    Gotu Kola – Induces clarity in thought, reduces anxiety and tension.

•    Oatstraw – Helps to improve concentration skills in both adults and children.

•    Rosemary – Improves concentration and memory.

•    Sage – Helps to improve memory.

•    Balm – Official name Melissa officinalis, also helps to improve memory.

Although many people believe that Ginkgo biloba is an effective herb to use for memory enhancement and prevention of Alzheimer’s disease and dementia, studies have shown results at both ends of the spectrum. In a randomized controlled study, 3069 volunteers aged 75 years or older with normal cognition were split into one group that received two doses daily of 120 mg of Ginkgo biloba and one group that received a placebo (DeKosky et al., 2008). The study was conducted over a period of 6 years, with 246 of those who received the placebo and 277 of those who received the Ginkgo biloba developing dementia or Alzheimer’s disease by the end of the study, indicating that it was not effective in reducing the overall incidence rate of dementia or Alzheimer’s disease. Paul Solomon, et al. (2002) reported on a different study of 219 people over the age of 60 who were also split into two groups, with one group taking Ginkgo biloba and the other group taking a placebo. This study lasted for 6 weeks and indicated that there was no measurable benefit to taking Ginkgo biloba.

Other studies of Ginkgo biloba, however, have reported results similar to currently prescribed drugs such as tacrine or donepezil, which are commonly prescribed for Alzheimer’s patients (Perry et al., 1998). Some researchers believe that the discrepancies between studies may be a result of the types of people selected and that race and overall health, as well as other factors, may have contributed to the varying results. It is possible that those who take Ginkgo biloba develop a tolerance for it, therefore explaining why longer studies show no memory improvement, as it may work only for a short while.

There are many more herbs that have been believed for generations to help to improve memory, and more research is being done every day to determine which ones are the most helpful with the least side effects. It is important to stay informed as new information is found regarding how to keep our brains and bodies healthy every day. Scientific data is being found every day that relates to memory and brain health, and with a large number of the world’s population reaching old age, this type of research is more urgent than ever.

If you are under medical care, it is wise to consult your physician before changing or adding to your diet, as some of the foods, supplements and herbs mentioned above may not be recommended for certain conditions, or may react with prescription medications. Your physician can help you decide what is best for your health and lifestyle, and may be able to suggest changes that will be of the most benefit to you. Sudden drastic changes in diet may cause gastrointestinal problems, so go slowly and gradually until you reach the goal you are working toward, taking smaller amounts at first and increasing them over a period of time.
