It is well established that many herbs can improve mental capacity; clinical studies have found that gingko, Panax ginseng, Siberian ginseng and gotu kola can significantly boost concentration, alertness, aptitude and even intelligence. It is not always clear how this happens, but some studies have shown that ginkgo, Panax ginseng and Siberian ginseng can increase the activity of some of the brain’s neurotransmitters. These are the chemicals that transmit messages from one nerve cell to another – and essentially enable thinking. Other herbs such as for example rosemary can influence concentration through their fragrance alone. Here are some examples of brain boosting herbs:

Gotu Kola is an ancient herb, known from the Ayurvedic medicine, and used to improve both memory and lessen the symptoms of senility. Studies have shown that it can improve concentration and attention. Some of Gotu Kola effectiveness may be explained by B-complex vitamins.

Ginkgo Biloba is an ancient Chinese herb that has been shown to increase blood and oxygen flow to the brain. This will eventually improve mental function and promote alertness and short-term memory. It also stimulates brain receptors that release a neurotransmitter (acetylcholine).

Rosemary is a common herb that increases circulation within the brain and can thereby stimulate concentration and memory. Inhaling rosemary essential oils can heighten the senses.
