Well, Kerol said there can't be too much, so I'm opening my floodgates

After reading the description of the Herbal skill, it seems to say a potion made out of an herbal base will be closer to nature. Then reading more about alchemy, it seems very much a mineral and dust kind of art. I spent a lot of time trying to tie the Herbal craft with the Alchemy craft. In my mind, they seem somewhat related like the Metallurgy/Blacksmith pair. So maybe an alchemist can buy basic ingredients from an NPCs (say, like 50/50 quality), but you could also get them from a Herbalist PC (with the potential for better ingredients, ie 300/50). I stared at the 6-way magic chart and tried to tie it into the whole thing as well. So this is what I came up with, the six ways of herbalism...

Each way has a related stat and the same characteristics of the related magic way. Plants of Yliakum posses properties that link them to a specific way. These properties can be tapped into by making "bases" out of tinctures, infusions, and juices from the plants. I made a list of herbalist equipment that might be handy as well...
------
Burner- flame and flask for warming of liquids (warm->boiling->potent->residue)
Crucible- heat for solid materials (warmed->hot->reduced->ash)
Beaker- tabletop vessel for when heat is not required (light->[normal]->concentrated)
Drying Room- cool dark place to dry and cure herbs (moist->cured->dried->stale->)
Mortar and Pestle- for breaking up herbs (crushed->dust)
Strainer- for juicing plants and fruit ([juice of plant])
Alchemist Bottle- the rectangular ones like the colored potions, lesser potion of mana, etc
Table- got to have one

4x Night Bloom + Oil into Burner (combine)-> wait wait wait-> Concentrated Night Bloom Oil
Wormroot Oil + Concentrated Night Bloom Oil + Alchemist Bottle into Table (combiine)-> 2x Dark Base

Cold infusions tend to take longer in RL so I applied it to the PS ones with the tag "(long time)" on applicable steps.
An alchemist will use bases and various alchemical ingredients to make unique potions. I thought use of a Yliakum version of the "Philosophers Stone" would help along the nonsensical chemical reations that are inevitable, so maybe a Orichalc Shard?...

I threw gold dust into the last one as the Blue way and Red way are in opposition. Gold seems to make everyone get along, why not The Ways as well

Kind of ran out of inspirational steam at the end there and the recipies got simplistic, but you get the idea. Just one big brainstorm anyways.
