The action of ginkgo focuses on the circulatory system at various levels. It is a vasoprotector, vasodilator, and antiplatelet aggregator. It is a powerful vasodilator that reduces the resistance of arteries to blood flow. It decreases the permeability of capillaries, reducing edemas. It is a good venotonic, toning the walls of veins and facilitating blood return. In addition, it improves blood flow to the brain; it has been shown to be very useful in alterations of brain function of ischemic origin (senile dementias, lack of attention/concentration). Usage: Take 15 drops three times a day. Warnings: It may enhance the action of antiplatelet aggregators, oral anticoagulants, and heparin. In case of pregnancy or lactation, consult with a healthcare professional.
