Usnea, Lo Han Kuo, and Honeysuckle are favored by Asian cultures, and were the only substances which worked for many people plagued with last Spring's flu. Usnea is a lichen whose actions are similar to Echinacea, but many folks say it is even faster. Lo Han Kuo is a Chinese tea remedy derived from a delicious plum. It can clear your lungs and sinuses rapidly without the discomfort of other expectorants. Both are served at Two Stick Sushi Bar.
Honeysuckle blossoms cool a fever while fighting virus.
Incidentally, in case you don't know, antibiotics kill bacteria, not viruses, so although antibiotics are fine for the secondary infection which usually affects the lungs, they pare no match for cold or flu viruses. Researchers agree that these are a direct result of indiscriminate use of antibiotics over the last few decades. The developers of antibiotics warned of this dangerous potential in the 1930s. They indicated antibiotics for use only as necessary, not for every cold and flu. So, I urge you to explore some alternatives and give germs a passport to another planet.
