I am in the preliminary steps of creating an Herb-gathering / Alchemy system for my OSR game. I will be using real world herbs, as I feel that's more interesting than any list of fantasy herbs that I could generate.
The system will include:
- Tables to randomly generate which herbs are found when gathering.
- List of herbs and their properties. (Healing, Poison, etc.)
- A system to determine what happens when different herbs are mixed.
I have some ideas on how I want the system to work, but what I mostly need right now is data on the herbs. Are there game or supplements that have large lists of herbs and their properties? I've found a couple of real world websites, but the information is not laid out in a very consistent manner. I'm especially interested in anything that references the commonality of the herbs.
