Hey fellow WoW players! Welcome to my blog and this article about farming Swiftthistle. There is no need to ever buy it on AH if you follow my guide. Quite the contrary, you can even farm it to sell on Auction House and earn lots of gold this way.
If you have hard time earning gold in WoW I recommend using this in-game add-on, called Zygor Guides. It really helps you with lots of aspects in the game, including Farming, Crafting, Gathering, Auction, Leveling, Professions and much more... Though, the add-on costs some money, but is well worth the price. They also have a FREE TRIAL you may want to try.
Swiftthistle is not an independent herb, but you get it from gathering Mageroyal and Briarthorn. So if you want to farm it just follow the same path as for those herbs. It really doesn't matter which one you pick up because the drop rate is the same for both.
Hillsbrad Foothills - Mageroyal
This is the path I took when gathering Mageroyal. Follow it and you will get lots of Swiftthistle as a side product:
Hillsbrad Foothills - Briarthorn
And this is the map for farming Briarthorn. Check it out:
