Notes on the Use of Herbs
Unless otherwise indicated in text, any cut herbs and 
preparations of herbs only have a shelf life of 3d6
weeks. Dried herbs have a shelf life of 1d4 years if
kept in a sealed container away from moisture (but not
all of these herbs can be used in a dried form).
Potions, on the other hand, have an indefinite 
lifespan - which is why they're more expensive yet
still desirable.

A rule of thumb for purchasing is that the chance of
purchasing an herb in a large city WITHIN its native
region is equal to the chance of finding it in the
wild (and the price will remain the same); the chance
of purchasing an herb in a large city OUTSIDE of its
native region is equal to half the chance of finding
it in the wild (and the price will be half again as
much); and the chance of purchasing an herb in a
large city OPPOSITE of its native region (eg., artic
vs. desert) is one quarter of the chance of finding it
in the wild (and the price will be doubled or tripled).

The GM of an individual campaign must rule on the use
of this guide. They must decide whether or not they
wish it to be used at all, and they must modify it to
fit their campaign. Some of the herbs contained in
this guide are extremely powerful, and if they are
overused they will unbalance the game. The prices
given for herbs are only guidelines and must be
treated with common sense. In plague years, for
example the cost of herbs that protect against plague
will increase incredibly. And if the characters
stumble into a herbalist while supporting a friend
who is on the verge of death from snakebite, the
herbalist may decide to charge well above the going
rate. Some apothecarists are nothing but charlatans
and will sell anything while saying it is a wondrous
herb.

Once again, I must point out that this guide is
intended for use in games only. Do not use it as a
guide to herbal medication. Many plants are highly
poisonous and experimenting can be extremely
dangerous. I accept no responsibility for any misuse
arising from any edition of this guide.
