Ginkgo biloba is considered one of the best remedies to improve blood circulation, due to its ability to dilate blood vessels and facilitate blood flow. This plant, originating from China, not only improves circulation but also has antioxidant properties that combat free radicals responsible for cellular deterioration and various degenerative diseases. Crushed ginkgo biloba leaves are used in teas or extracts. Precautions should be taken as it may enhance the effects of anticoagulants.
