Consumables of a Witch

As with the witch's tools there is no one size fits all.Some witches will rely heavily on their "magical shelves" - some very little. Below is an idea of some of the things some witches may choose to use in their workings. It is by no means exhaustive.  A witch can and will use pretty much anything to hand in her workings and the skill of a witch lies not in acquiring the "right things" but in learning to improvise with the things that she has.

Candles

Candles are used to invoke the element of fire, to burn, to banish and to seal. The colours of a burning spell candle are often associated with the correspondences relating to that colour and by using the candle the witch brings the power of the associated correspondence into the working.

Herbs

Herbs are used to make potions, tinctures, ointments and teas. They can be used for medicinal purposes, cleansing,blessing, purifying, halluciogenic purposes and for most other general magical purposes. 

Salt

Salt is both purifier and protector for the witch. It can be used to protect the parameters of a home or a circle or it can be carried on the person for personal protection.

Incense

Incense has a range of purposes including purifying, protecting and inducing different states of consciousness. The properties of the different types of incense bring different powers and energies to a working.

Oils

Oils can be used for burning or for anointing to bring the different properties of the essential oil into a working. Oils as with incense have established correspondences that can be utilised to draw different purposes into the magic that is being cast.

Earth

Soil can be used for grounding, bringing the energy of a specific place to a working or invoking the element of earth. Soil from a graveyard is often used in Witchcraft for protection purposes.

Blood

Blood is most often used to personalise a spell ( to put oneself into it, so to speak).
Blood from one person can also be used to cast protection over another. Obtaining blood or fluid from an individual can be used in spells to either help and heal the individual or to hex or curse them.

Animal Parts

Animal skulls, hair, feathers etc.
can be used to bring the characteristics associated with that species into a working.
