gold coin grass

Hi,
does anyone know whether gold coin grass, coptis and curcuma are available from sources in the US?
I've been having attacks every day in the last 3 weeks. I ordered them from Julia Chang in Canada 12 days ago, but haven't receive them yet although she had sent them by express mail. I assume the package got lost. I need these herbs ASAP, so I wanted to order them overnight from a US source. (Julia Chang cannot send overnight packages to the US.)
