While the best tool a Witch or Spiritual can have is themselves, often many forms of spirituality may require, or simply enjoy the usage of tools. These range from ceremonial tools such as Athame, Wands, and Staffs (tools used to control the flow of energy and work it to the users' intention), to simpler things such as herbs, candles, and even colours.
There are hundreds of possible ingredients, so I will include as many as I can find, however, this will not be ALL of the possible associations and possible ingredients, and I encourage you to do your own research into things you may have at hand.
As an added notice, some ingredients are part of Closed Practices, and as such are not to be used for general practices due to either racial discrimination, overuse, or general spirituality for that practice. If you would like more information on Closed Practices and their ingredients and connotations, I have a list here.
