In Honduras, tea, antibiotics (yes, I know this is wrong), and injections are considered the best cures for la gripe (a cold or flu). Also, wearing a cap to keep your head warm is a good idea. :-)
La Gringa: Do you want me to make you some tea?
El Jefe: Yed. (cold talk for: Yes)
LG: I forgot the name of this in Spanish.
EJ: Manzanilla.
LG: Oh, yeah. . . . Uh, I forgot the name in English, too.
EJ: Chamomile.
LG: Oh, yeah.
EJ, walking away: Heheheh.
Everything I've read about chamomile tea says that the tea is made from the dried flowers. This is a photo of the chamomile that is sold here. As you can see, it is primarily stems. But everyone seems to think it works anyway.
Last year, I cured El Jefe of a cold in one day with a jamaica-ginger-lemon tea. The problem was that I overdid the ginger and found out later that too much ginger causes diarrhea. (Sorry about that!)
