The first two were first used by Native Americans, the third used by Western and Eastern cultures for several thousand years, and the fourth by the Chinese. I don't suggest taking all four. Experiment a bit, see what seems to work the best. Echinacea is the most popular. Don't laugh, I read some time back of a well-done study showing it soothed inflamed membranes and promoted drainage, both good things for a cold.
Antibiotics are powerless against the virus.
They waste your money, can cause undesired effects, and if used when not needed will eventually be useless when needed. Aspirin, Acetaminophen, Ibuprofen, Naproxen, etc. can be used to treat aches and pains. Fever seems to weaken the virus, and shorten its life. The body is wise. It's probably best to leave a fever alone unless it makes you uncomfortable.
