About 10 years ago, the family started blending this fruit with banana and a little guarana (a mild natural stimulant).
Caffeine is often added or ‘stacked’ to ephedrine-based products, as it enhances and prolongs ephedrine's effects; the herb guarana is also a source of caffeine.
Gentle in its actions, guarana can be used to improve mild depression.
One recent animal study compared the effects of guarana to those of ginseng.
These products, available in health food stores or on the Internet, contain stimulants such as ephedra, caffeine, and guarana , with variable additions of common herbs or vitamins.
