Apothecary’s stat combination (Healing Power/Toughness/Condition Damage) is only available on level 75+ items. I suggest to add it to lower levels by adding various shell items (e.g. soft shell / shell / hard shell) for crabs, turtles and other shelled creatures. This will bring this item in line with other fine crafting materials, and will allow to add a Healing Power/Toughness stat combination for level 21-60 items.
As for jewelry, various flowers can also be added to lower level plants to complement passion flowers, or alternatively mother of pearl can be added (makes sense IMO, since Pearl gives Healing Power, and Mother of Pearl will give Healing Power/Toughness).
