lan gui ren (ginseng licorice oolong)

It looks like TeaSpring might be your best bet. I’ve never had this type of tea, but TeaSpring has received fairly good ratings, and their shipping is remarkably cheap ($4/worldwide).

I’ve never heard of this tea prior to now, and now I’m kind of intrigued :)

Oh man! You’re in luck! Teavivre just posted a topic saying that they started stocking this exact tea!

Price looks great! YOu can get a sample to be sure you like it and Teavivre ships worldwide at a decent price. :)

Thanks Dylan and Mercury. Wow, $4 worldwide shipping!

Seems like there are two typical versions of this tea: chinese ginseng+licorice,
and american ginseng version as currently stocked on teavivire.

FYI, generally, you should avoid anything with ginseng if you have a cold, flu, or simillar acute illness.
