We were friends with this chinese lady whose parents ran one of the local chinese food restaurants years ago so we were hardcore VIP (they liked us)... so we got to go eat int he back room and got the special treatment good stuff.... anyway, we go in there onetime and my mom has the worst cold, and he goes "Hoe on Cheena, I be right back, fix cold good!" THen he cames back with a big jar and a little bowl and a toothpick. The bowl has some of the stuff from this jar in it, he dips the toothpick in the bowl and dips it into the wor wonton soup.. he tells her to breath the steam, her sinuses just like... emptied. and cleared right up and she could breath. he gave us the jar. It's some hardcore spicey shit, like... my tongue just combusted spicey. I mix it with my mr.noodles and turkey soup and wonton soup and shit. It's great. We've had the jar for 8 years, and its about the size of a fist. Still only halfway through.
Not sure about cough remedies besides buckleys and tea.
