at around 47 i went out bought 60 irit seeds and 80 kwuarm and had a friend help me farm them all. it took a loong time lol, but then i got 2nds myself and mixed the irit to sup atk which got me to about..52 i think? either way i say use sup atks,prayer potions. though ranarrs are hard to get in bulk, if you have spare money and have done some of rfd but harralanders for 1kea or so then buy choc bars and crush to dust make energy pots regular is good for a lvl or so quickly. do any of those methods until 52, this is where i made my ENTIRE herblore lvls pretty much. do nature spirit and use the silver sickle (B) to get fungi, this works best with kharyll teleport (ancient spellbook) or a house tablet with kharyll rift, you ake your isckle to the swamps and cast bloom repeatedly until you have a full inventory of fungi, then bank. charge prayer (i use the tablet method and use alter in my house) then bank at canifis repeat. i suggest you ge about 200-800 fungi. then go on forums and post buying all avantoes 1.5kea, 1.6 if over 100. while your post is up you can also look for people in w2 and search over forums. After u have all the avantoe you need mix super energies and sell for 1.9-2kea, this breaks you even and usually a lil bit of profit. i used this method from 52-63 herblore and its quite fast. i plan on using it until 72 herblore also.
