龍膽

• 李時珍。本草綱目，卷十三。

龍膽。釋名：陵游。本經註：志曰：葉如龍葵味苦如膽因以為名。

而學名的的由來則是還沒看懂的一段，出自維基英文頁：

• The name is a tribute to the Illyrian King Gent who used the flower to heal his wounded soldiers. The best known city in the Illyrian Empire where the flower was found is located in Southwest of Montenegro today, called Sac (Shas-Albanian)

這段話的內容另日再查了。
