Muscipular can be found in the field outside ice cave dungeon. Just warp to ica cave dungeon 1 then go outside portal there should be some there and other fields close by.
As for the aloe, if you have a biochemist you can create or summon a bunch on plants and kill them to farm it. Or you can ask some friends with biochemists If without, there's a map that spawns just plants in umbala dungeon 3 at the roots of yggrasil. You can warp to umbala dungeon 2 then enter the portal in the center of the map.
