For a little extra kick, I frequently add one or two cardamom seeds to coffee or tea. It tastes really good. Coffee contains that famous stimulant, caffeine. It's an old favorite for getting rid of that faint feeling. But other caffeine-containing beverages have also been used to treat fainting, including tea, colas and the South American drinks mate, guarana and cacao.
Hot chocolate works, too, since it also contains caffeine.
Here's an herb that's generously endowed with the stimulant compound ephedrine. The seeds have the most. Because of its stimulant action, country mallow has even been used to treat narcolepsy, a condition that gives people the overwhelming urge to fall asleep. Try making a strong tea using five teaspoons of this herb per cup of boiling water. Steep until cool.
