Ginkgo Biloba: Natural Supplement Overview

Ginkgo is believed to be one of the oldest trees in the world. It is native to Japan, China, and Korea, but was also grown in Europe and the United States in the 1700’s. It is sometimes referred to as the maidenhair tree.

The leaf of this plant is usually given to individuals who have Alzheimer’s disease. It has long been used to treat conditions that affect the blood flow in the brain. These conditions include loss of memory, problems in concentrating as well as mood disorders.ginkgo tree

It is sometimes used for individuals who suffer from leg pain due to poor blood flow.

Ginkgo Biloba has a long list of benefits. This could be because it’s been around for a long time now. In fact, it was used as a treatment for bronchitis and asthma in 2600 BC.

Also, this type of tree can live up to a thousand year. In China, Ginkgo trees can even survive for more than 2,000 years. Because of this, the tree is sometimes labeled as the living fossil.

In China and Japan, the plant’s seeds are roasted for consumption.

The dried leaf of this herb is now a popular supplement. It is available in different forms like tablets, capsules, and liquid extracts. The dried leaf can also be brewed to make tea.

This is considered a low dose and may be gradually increased if there are no side effects experienced.

For specific conditions, these are the dosage used in studies:

  • Anxiety: 80 to 160 milligrams of the leaf extract was taken 3 times a day for a span of 4 weeks.
  • Dementia: 40 to 480 milligrams per day. This dose was divided into three to four doses and was taken for a whole year. It was found that the most effective dose for managing dementia is 240 milligrams.
  • Vision problems due to diabetes: 120 milligrams each day for 6 months.
  • Leg pain due to blood flow issues: Daily dose of at least 120 milligrams of the leaf extract divided into 2 to 3 doses. This dose was taken for up to 6 years without serious side effects. The dose may be increased to be more effective.
  • Vertigo: 160 milligrams of the leaf extract may be taken daily for up to 3 months.
  • Premenstrual Syndrom (PMS): 80 milligrams of the leaf extract to be taken twice a day.
  • Loss of vision due to glaucoma: 120 to 160 milligrams of the leaf extract. This dose may be taken in up to 3 divided doses. No serious side effect was reported when taken long-term for up to 12 years.
  • Schizophrenia: 120 to 360 milligrams of the leaf extract was consumed each day for up to 16 weeks.

Nootropics

Ginkgo is a popular herb for improving cognitive function, memory and motivation. Studies suggest that it is not very effective. However, there are some reported cases where individuals get its nootropic benefits by taking 150 milligrams of the 50:1 extract.

Taking up to 300 milligrams of the herb is also effective for some in terms of improving memory without experiencing negative side effects.

Note that most studies on ginkgo’s nootropic effects do not use specific leaf extracts. The most effective extract to achieve ginkgo’s nootropic benefits is Egb 761. This is a patented extract that is commonly used to treat dementia but is also found to be effective in improving short-term memory.

Other nootropic benefits include a boost in productivity and concentration.

In other cases, ginkgo was able to improve energy and cognitive functions, but also causes bleeding in the brain and behind the eyes due to its blood thinning effect.

Considering ginkgo is a very common herb, the risk of bleeding from taking it is very low as long as it is not overdosed. Still, it is important to remember that ginkgo must be used with caution as it can cause serious side effects.
