Also known as: Memory Tree. Uses: Improves arterial circulation, cold hands and feet, Menière’s Disease, chilblains, tinnitus, impotence and poor memory. Description: This is probably one of the oldest medicinal herbs known to Man. Its use can be traced to the oldest Chinese Materia Medica dating back to around 3,000 BC. Traditional Chinese medicine describes the ability of Ginkgo leaves to benefit the brain. Today, numerous clinical trials have shown Ginkgo’s ability to improve brain function and therefore quality of life. How it works: The action of Ginkgo has been quite clearly demonstrated in various research tests. Direct action on the arterial circulation increases the blood flow through these vessels. At the same time, the herb has been shown to inhibit a substance known as platelet activating factor (PAF). This action further improves blood flow. Ginkgo has also been shown to have antioxidant effects, which are important in stabilising cell membranes in the body. Additional advice: Do not use alongside blood-thinning medicines such as low-dose aspirin or anticoagulants such as warfarin.
