Just a quick way to make money for Members with 34 and above herblore.
-What you'll need-
34 Herblore (said 3 times now x D)
Some starting gold, at least 100k and up would be advisable.
-Where to be-
Grand Exchange
-What to do-
1. Buy Clean Toadflax. You'll need 1 Toadflax for every item you make to resell.
2. Buy Vials of Water. Again, you'll need 1 vial for every item you make to sell.
3. Use the Clead Toadflax on the Vial of Water, making 14 per inventory.
4. Sell all of your Toadflax Potion(unf).
You should make about 200gp profit, which doesnt sound like much, but its pretty good.
Especially considering that it doesnt take long to make the potions at all.
