The Herblore NPC in Taverley gives you free guams and eyes of newts.
Farming is a way to get herbs. Dagannoths in the lighthouse drop a lot of herb seeds, requires Horror from the deep quest. You can also get seeds through thieving Master farmers, or killing other NPCs.
Killing Chaos druids or Cave Crawlers and later Flesh Crawlers will result in a lot of herbs.
Throne of Miscellania and Royal Trouble quests unlock Manage thy Kingdom where you can put the workers on herbs, provided you can manage to gain enough GP to keep the coffers full.
It shouldn't be too hard to raise herblore with these things.
