Andrographis for colds?
What's the experience of forum participants been with using Andrographis paniculata (sometimes sold as Kan Jang) to shorten the severity and duration of colds?
There's somewhat limited but encouraging evidence that this herb is effective and relatively safe to use. More limited data suggest it may (as with echinacea) act to prevent an upper respiratory infection from developing.
Some of the advertising hype seems over the top, but it sounds like this could be worth a try.
