Herbs and Mushroom Collecting To make a potion, you need alchemy skill of at least 2. Walk up to a patch
of mushrooms or herbs. Open your inventory up. Drag an empty flask over the
herb/mushroom. ( The "X" will disappear when the flask is over the right spot)
Note that not every patch of mushrooms / herbs will make a potion. If one patch fails to produce a potion go to another patch. I have found a patch of several mushrooms that would not produce a potion but a single mushroom a foot from the patch would give a potion.
Herbs:
Purple = Healing
White = Stamina
Blue = Magic
Mushrooms:
Red = Healing
Blue = Magic
White = Poison
Orange = Stamina
Flasks:
Small Flask = Minor Potion = Alchemy skill: 2
Flask = Potion = Alchemy skill: 3
Large Flask = Super Potion = Alchemy skill: 4
Also eat to raise health: meat, bread, cheese etc Open inventory and click on the food item, you can do this till you're full which can be before your health is fully restored.

sblack162 asked "What does it take to make invisibility potions?"
I don't know how to make shadow potions directly form herbs but you can drop a "Magic" potion on a "Stamina" potion to make "Shadow" potions. Shadow potions make you invisible. (As long as you don't left click, Warriors can do damage with their right click special move without becoming visible.)
You can also make "Restoration" by dropping a "Heal" potion on a "Magic" potion, an "Elixers" potion by dropping a "Stamina" on a "Restoration" potion and a "Strength" potion by dropping a "Stamina" potion on a "Health" potion.
Dropping multiple potions on the same amount or greater of the other will create the number of potions equal to the smallest quantity you drop. i.e. dropping 10 "Magic" potions on 20 "Stamina" potions would give you 10 "Shadow" potions with 10 remaining "Stamina" potions.
So . . . you can make the other potions but you need to have or make the base potions first . . . =)
If anyone knows a mix of herbs to make shadow potions please post the ingredients.
Honey Honey will temporarily give the following +50 Hit Points, +50 Magic, +5 Strength, +5 Agility, +5 Intelligence. There are only so many honey racks and empty jars in the game, and once they’re gone, that’s it. I gathered it without any alchemy skills at the time IIRC.
You will find everything you need to gather honey at Mardaneus's house early in the game. It is scarce after that and rarely found. I used it in the first catacombs. You will find a few jars later in the game but not often enough to make it useful on a regular basis.
Some food items are bad for you,
