Digitalis and other plants containing cardioactive glycosides are infr
equently used today for congestive heart failure. Hawthorn has positiv
e inotropic effects and accelerates the heart rate but its use is rest
ricted to the prevention of angina. Ginkgo is employed in chronic cere
bral ischaemia and intermittent claudication white horse-chestnut is e
ffective in chronic venous insufficiency. These vegetable drugs are us
eful in themselves and also in association with more effective therape
utic agents. (C) 1998 John Whey & Sons, Ltd.
