Many different herbs can be found in MUME, and a great many of them are used in various herblores.
Some of these can be crushed, for instance:
"a woody stemmed plant", when held and crushed, will become "some narrow leaves"
When making a herblore, it is important to see the difference between the crushed and the original plant.
As usual plants/bushes/shrubs doesn't have keywords, but leaves/flowers/petals have it. To crush plant/flower/etc type "remove <weapon>", "hold <plant>" and "crush <plant>".
