For those suff

For those with sinus colds, congestion: White tea with lemon and honey. Drink it all day long. The caffeine will keep you going too. A nice thing about loose leaf tea is that you can usually infuse it many times. Good bang for your buck, and it'll shorten your cold. Yay!
Also for your sinuses (colds, allergies, sinusitis) - this doesn't have anything to do with tea, except that the apparatus looks like a teapot, and that can only be a good thing in my books - use a Neti Pot.
For sore throats, I like Honeybush, or a green tea with lemon and honey.
I also like the "usual" tisanes, like echinacea, chamomile or mint for soothing purposes.
For general good health (I believe this will rejuvenate your arteries, and possibly fight cancer too!): Mix some turmeric, black pepper and sweetener (I like black molasses) into your black tea. It's not for everyone. My friend Rebecca said it was like a curry broth. Admittedly, it's an acquired taste. But there are good stories coming out of the scientific community about the excellent effects of turmeric, and I'm going to take that to heart.
Like I said, I don't really think these will cure you of anything, but they certainly can't hurt to drink (well, except the Neti Pot. Don't drink from that. Snort it up your nose instead!) And besides, a cup of something warm usually makes you feel better anyway. So if you're feeling a little something coming on, don't panic. Just put the kettle on, get your favorite blanket and hot- water bottle and sip something wonderful.
And get better soon, 'cause personally I'm getting sick of toting the Purell around. :)
