remedies for colds and "gan mao"

today, my students shared some cold remedies with me...

beat an egg, stir in boiling water
mix freshly squeezed lemon juice with honey
stir lemon-honey mixture into egg mixture and imbibe

here's another...
place 1/2 luo han guo, handful of northern chinese almonds (bei xin), a small bunch of dried bok choy, chicken bones/breast in pot with 4-5 bowls of water. stew for 2 hours.

i tried the above; it doesn't taste bad at all...in fact, reminded me of Brand's Essence of Chicken. let's see if this really works.
