There are a couple of homeopathic things that can be done, but you can't really beat good rest and lots of water. That's the honest truth. Making sure I'm well-rested and hydrated makes a big difference. Warm water and honey is a go-to, I don't really drink tea unless it's absolutely organic, because otherwise the caffeine will dry my voice out for some reason.
