ginseng
薓 is a rare kanji that refers specifically to ginseng, the medicinal root.
薓 is a phono-semantic compound with 艹 (grass/plant) and a phonetic element related to 侵 (シン), indicating a plant whose name sounds like シン. The exact historical development is uncertain.
The grass radical 艹 sits above a complex lower part that looks like a person 亻 with a broom 帚-like shape, as if someone is carefully digging up the precious ginseng root from the grass.
For シン, imagine a ginseng root shaped like the letter 'C' being pulled from the ground: 'C' in ginseng -> シン.
