It's commonly used in cold formulas as a decongestant. "Ephedra is a great bronchial dilator," McQuade-Crawford says. It helps asthma sufferers by opening the sinus passages and has an antihistamine effect which aids chronic and acute allergies. Ephedra also acts as a circulatory stimulant to blood pressure and heart function; it elevates blood pressure. Ephedra's main constituent is ephedrine, which increases adrenaline secretion in our bodies. The boost you get from ephedra stimulates certain glands, muscles and tissue functions, while it suppresses others. "In the long term, ephedra's adrenaline overdrive can lead to chronic stress and even to degenerative disease," warns McQuade-Crawford. She notes this is important for people using ephedra for dietary weight loss or "pep pill" purposes because the effects of ephedra linger in the body long after the herb is gone. "Ephedra shouldn't be used with drugs for the heart or for the lungs and never with antidepressant drugs. It's not for use with the weak or the ill and when used long term, dosages should be conservative," McQuade-Crawford cautions. Hawthorn The berries of this flowering shrub are best used for the heart, says McQuade-Crawford. Hawthorn aids the heart's pumping action by opening the coronary arteries to nourish the heart muscle. The herb can also slow a rapid heart rate and strengthen a failing heart. Hawthorn usually lowers high blood pressure, especially a raised diastolic high blood pressure, and it benefits low blood pressure due to weak heart muscles with arrhythmia (irregular heart rhythm). "Hawthorn takes a long time to do its best -- six months or longer. In the style of a true herbal tonic, it can be taken safely and effectively over time for its best effects," notes McQuade-Crawford. Ginkgo Biloba Ginkgo Biloba extract from the ginkgo tree has been shown to benefit visual function by improving microcirculation to the eyes especially among patients suffering from senile macular degeneration, a common condition thought to involve free radical damage, says Steven Schechter, N.D., author of Fighting Radiation & Chemical Pollutants With Foods, Herbs &Vitamins (Vitality, Ink). More than 280 scientific studies indicate standardized ginkgo extract prevents and/or benefits ailments such as vertigo, tinnitus, inner ear disturbances, memory impairment, ability to concentrate, anxiety, depression, neurological disorders, senility, circulatory disorders, edema and Raynaud's disease (a vascular disorder). Ginkgo extract improves the quality and increases the quantity of capillary circulation, thus increasing blood flow to the brain, heart and tissues in organs and glands, Schechter says. In addition, he notes, the flavonoids in ginkgo are potent free radical scavengers. More Videos With Dr.  MacLeod- Lutchin CLICK HERE
