The Witch's Bottle

I have to admit that when I first saw this term I was very intrigued. Here is a further explanation of what a witch's bottle is:

"
THE WITCH’S BOTTLE

The Witch’s Bottle is a very ancient type of spell, which has countless
variations. The idea of performing a spell and sealing it in a jar is as old
as the manufacture of jars, and may be regarded as a portable version of
burying a spell in the Earth -the jar here representing the womb of the
Mother.
Many examples of this sort of spell have been found by archeologists,
though modern versions tend to be rather different from ancient ones -partly
due to the difference in materials readily available for magical working. In
ages past anthropomorphic jars were especially popular for this sort of
working, the jar itself then taking on the character of a spirit helper to
aid the spell’s unfolding. Sometimes the whole jar would be made in the
likeness of a human being, or
animal, sometimes only the face would be shown. The so-called BELLARMINE
JARS, bearing the likeness of the Old God -often in tripple form- were
commonly used for this sort of undertaking and are strongly associated with
it.
Today, we commonly use any sort of jar or bottle that appeals to us, or
is convenient to use. Decorative jars are often favored, but ordinary glass
jars and bottles -either plain or self-decorated- serve just as well.
For this particular Witch’s Bottle, you will need the following things:

A small jar -such as a baby food jar, or a medicine bottle.
A larger jar -such as a canning jar, or a decorative canister.
A bit of paper and ink -red ink would be preferable.
Some herbs -a combination of Parsley and Sage might be a good general choice.
A bit of essential oil -vanilla might be a good choice.
Some stones -aquarium gravel would be good, as it is small and easy to handle.
A quantity of water.

Choose a time when you will be able to work unhindered. If possible it
is best to make the bottle during the Waxing Moon.
