Headache, dizziness, trouble sleeping, insomnia, and memory loss….are typical symptoms of cerebral ischemia, also known as cerebral circulatory insufficiency (1).

Cerebral circulatory insufficiency, also known as transient cerebral ischemia, occurs suddenly due to a lack of blood to feed brain cells, and reduced oxygen and nutrients to the brain, causing brain neurons to lack the energy to function, thereby affecting the functional activities of the brain.(1)

Cerebral circulatory insufficiency is now known as a fairly common disease in middle-aged and older people, especially in intellectual workers and the elderly (1), according to statistics, about two-thirds of the elderly age with this disease. In addition, according to experts, this disease is increasingly “rejuvenating”(2). Symptoms are quite faint and general, not easy to detect and easily mistaken for other diseases.

Using herbs that promote blood circulation to nourish the brain, and improve symptoms of cerebral circulatory insufficiency is very popular recently. Here are 3 effective brain tonic herbs:

1/ Ginkgo biloba (3,4)

Ginkgo is dubbed as a sacred plant good for the human brain. Since the 1900s, it has been used as medicine in the West, when the extract of the leaves has the effect of improving blood circulation, especially in the blood vessels of the brain and extremities. Currently, in the US and Europe, preparations with high Ginkgo biloba leaves are now one of the best-selling herbal medicines.

Ginkgo is commonly used to treat dementia, caused by a lack of cerebral blood circulation. It helps improve thinking, cognition, and memory in people with Alzheimer’s disease. Doctors also use ginkgo to treat cerebral and peripheral circulatory disorders, macular degeneration, vestibular syndrome, tinnitus, depression, anxiety, stress, thrombophlebitis of the extremities, syndromes Raynaud.

Ginkgo leaf extract contains high levels of flavonoids and terpenoids, which are powerful antioxidants that neutralize the effects of free radicals. Therefore, the extract of ginkgo leaves helps to slow down the aging process and neurological diseases.

2/ Blueberry (5,6)

Blueberries are native North American plants, rich in nutrients, and considered the king of the antioxidant food group. More specifically, anthocyanins, pterostilbene, and organic acids are antioxidants found in blueberries.

The precious biological active substances Anthocyanin, Pterostilbene, and these organic acids are neuroprotective agents because they can cross the blood-brain barrier, neutralize free radicals and fight related diseases such as Alzheimer’s, dementia, and vascular diseases.

One study found that when older adults with mild cognitive impairment drank blueberry juice every day for 12 weeks, there was some improvement in brain function (7). A 6-year study of 16,000 older adults found that blueberries and strawberries were associated with a delay in mental aging by up to 2 and a half years(8).

3/ Ginseng (9,10)

Ginseng, a valuable traditional medicine, is used popular to improve health and reduce stress and fatigue. The modern research shows that ginseng can improve the metabolism of brain and enhance the flexibility of the nervous system, improve memory ability(10). Ginseng effectively regulates the immune response and the hormonal changes due to stress. In addition to suppressing the occurrence of psychological diseases such as anxiety and depression, ginseng also prevents stress-associated physiological diseases.

These pharmacologically active constituents, ginsenosides, have been shown to support neurogenesis, synaptogenesis, neuronal growth, and neurotransmission, thus helping to protect the central nervous system from unexpected events; ginseng is also reported to be excellent for improving memory, directly preventing degenerative brain diseases such as: Alzheimer. In an animal depression test, ginseng demonstrated similar effectiveness to the commercially available antidepressant, fluoxetine.

Ginseng is used in many preparations: ginseng tea, ginseng wine, capsule, liquid, food, remedies….



According to eastern and western medicine, herbs: ginkgo, blueberry, and ginseng are proven to activate blood, increasing blood circulation, improving headache, dizziness, and memory decline… due to cerebral circulatory insufficiency.

Today, with modern medicine and pharmacy, precious biological active ingredients in these herbs are extracted and prepared in the form of tablets, and soft capsules. A combination of herbs in the same pill with a reasonable amount of daily use is very convenient for patients.

Products containing the above herbs will effectively improve the symptoms of cerebral circulatory insufficiency. Patients should carefully search for information about brain-tonic herbs, choose products from reputable pharmaceutical manufacturing companies, and have production experience with products with high-quality standards.
