Chaos Druids are the best way for members to obtain herbs. They cast bind on their victims, which reduces your attack, rather than binding you in place. The Druids in Edgeville Dungeon ARE aggressive.
For lower levels, take some dragonhide or leather armour. For higher levels, you don't have to worry about bringing armour - a dragon weapon will suffice. Again, for higher levels training on them in Taverley dungeon, don't worry about bringing teleport runes, as you should be able to kill enough to obtain some laws and airs (for Camelot Teleport).
A crazy, evil druid.
