Lab trials have demonstrated how ginseng appears effective for memory impairment.
Among mice given dosages of ginseng extracts, remarkable improvements in water maze tasks were exhibited and ginseng was shown to activate neurotransmitter activities that promote memory enhancement.
This herb is more than just an aromatic spice. Rosemary has also been traditionally used to improve memory.
Science backs this tradition since like gingko biloba, rosemary has been shown among laboratories to have antioxidant properties that neutralize free radicals.
One study suggests that when used in aromatherapy, rosemary can reduce cortisol levels and therefore, anxiety.
Another study verified the usage of rosemary, combined with other essential oils, to alleviate stress and increase concentration and memory of graduate nursing students.
Experts believe that sage contains active ingredients that boost the chemicals that trigger transmission of messages within the brain.
When scientists from the Universities of Newcastle and Northumbria tested 44 people by having them take either sage or a placebo, results showed that those given sage performed better in a word recall test.
They also suggest potential benefits of sage for patients living with Alzheimer’s.
Experiments have shown sage boosting the same brain chemicals that drop when one is afflicted by Alzheimer’s.
