Gentian Root is the dried root of Gentiana macrophylla
Pall, Gentiana straminea Maxim, Gentiana crassicaulis

falls into two groups and are known as "Qinjiao"
and "Mahuajiao" respectively. The drug derived from
the last one is commonly known as "Xiaoqinjiao".
The drug is collected in spring and autumn, removed from soil.

in the sun, piled up to evaporate the water contained in the
drug until a reddish-yellow or greyish-yellow colour is developed
on the surface, spread out and dried in the sun; or dried
in the sun directly after collection; as for "Xiaoqinjiao",
the black bark is rubbed off freshly and dried in the sun.
