low end herbs sell out almost instantly on my server, and ofcourse, the high end herbs will sell too, especially when people start to do MC, and start needing the Greater Fire Protection potions... for me myself, im an a guild with alot of 60s, and because of this, my Alchemy is 300 at lvl 40, which allowed me to take up Enchanting too, meaning i am making more and more money, at lvl 40 im sat on around 800g with one or two epics, and a nice full set of Blue items. My best sellers are most notably, the arcanite transmute, which can sell whenever its available.. and any of the greater potions, one or two others ive managed to sell well, are the Rage potions, helps selling these over honor weekends for wsg etc.
