禁藥

禁 = 林 + 示 : There's a small forest of two Christmas trees (林) in front of the encampment ((e)n4). Although there's a sign clearly stating that it is forbidden (示) to touch the trees, Joan of Arc (ji) set up her guideon (示) so that it is supported by the two trees and she can practice pull ups.

药 = 艹 + 约 : Maud Younger is on a date in the aorta, but she has to pass gas all the time. In the bathroom she desperately eats a sheet of artificial lawn, thinking that it should be the right medicine for her.
