Yes, but sadly, I had to make it by photocopying all of the herb charts and tables from all of the Companions and sticking them in a 3-ring binder for easier reference.
The best collection of herbs is ChL&CaL pgs 29-31. You can even roll 3d10 for a random herb generator. RMC-I has another chart of breads/herbs/poisons as well. Those two tables are the best major listings. Beyond that, I had to photocopy everything to include into one binder.
