Herbalists are able to pick herbs which are the main component of most Alchemy recipes. Upon learning Apprentice Herbalism, a character is able to use Find Herbs to view nearby herb nodes on the minimap. In the Outlands, characters with sufficient herbalism can use the skill to "skin" certain enemies, such as bog lords, which can come in handy sometimes. Motes of Life can also be found while picking herbs, as well.
COMPLEMENTARY PROFESSIONS
Alchemy
Since the main use of herbs is in Alchemy, it is the most useful crafting profession to take with Herbalism.
Skinning
On a first character, Skinning and Herbalism is a good pair for making money, since all of the materials can be sold. Skinning is also ideal because it doesn't have a tracking skill (except for hunters) so Find Herbs can be active at all times.
Mining
Not ideal for farming since two tracking skills cannot be active at the same time, Mining and Herbalism has the potential to make loads of money as well. However, all of the ore and herbs will take up a lot of bag space.
Enchanting
Mana and Wizard oils take herbs for creation, and selling off any extra herbs is a good way to fund the leveling process of enchanting, as well.
MONEY
There are many useful herbs that can be sold for hefty sums. Felweed is always in demand because it is used in many potions. Terocone is easy to find in Terokkar Forest and is one of the more expensive herbs. Nightmare Vine is also a very high value herb. It can be found only in Shadowmoon Valley and sometimes gives Nightmare Seed, which is extremely useful. Ancient Lichen is found in Auchindoun and Coilfang Reservoir, and also sells very well.
Killing and using herbalism on the Bog Lords and Giants in Zangarmarsh is also a great way to farm for Primal Life, which are used in many different recipes and can sell for a good amount of gold. This will also yield a lot of Unidentified Plant Parts and Bog Lord Tendril, which have some demand on the AH, but can also just be vendored for a good amount of money.
A great way to finding herbs is to use an addon that keeps track of spawn locations for herbs, such as Gatherer or Cartographer.
