So in the Healers Handbook Druids get the Druidic Herbalism option as an alternative Nature Bond. It allows you to make herbal concoctions, which fuction like potions, and is effectively Brew Potion using exclusively the Druid Spell List.
But of note, starting at first level you can make a number of concoctions equal to your Wisdom modifier
FOR FREE. The Druid even has the option to sell these concoctions as potions (with a side note of people maybe doubting they are actually potions). This is pretty damn potent at first level, for adventuring and gold.
Of course you are limited to how many potions you can make later on with a 1000gp daily cap, but wait, at 4th level the time to create potions is cut in half, and at 7th you can make one in a minute.
On top of that they can make their potions look like different potions, and can make concoctions above 3rd level, though those concoctions act as alchemist extracts (still decently potent for passing buffs around or other uses).
It is detailed on the pfsrd druid page
HERE. I might be misreading somewhere here, but if not this is a really strong option, which given it is a trade out for Animal Companion you would expect something worthwhile.
