The hows are related to the correspondences of the ingredients .Depending on purpose of the potion you would add the corresponding herbs while working during the corresponding moon or planetary cycle.
I would start with kitchen witchery.
But be careful, don't let your scientist side get in the way. Magic is about working with energy, it won't fit in any frame of science, logic or common sense :) Healing herb potions will be easy to understand and explain in science terms, but hexes is a different story.
The only "energy" used for potions is the energy needed to gather and mix! As for saying that magic should not be mixed with science; well,the original meaning of the word Science is "knowledge". And magic is surely that!
Hexes? They are "beliefs"; magic is real!
In England,before the Romans came, we were not even called "witches". We were called "the elders" or "the wise ones"; not only healers, but counsellors, giving advice on the problems of life. It was the Christians who started calling us "witches".
-Brysing maybe I didn't expressed myself correct. What I wanted to say - that when you are expert on smth, it might be difficult to work in other fields. But of course it depends on person :)
Potions are any wet form of magic, even blessed water is a simple potion. Tea is the most commonly understood potion. Plant material is soaked in hot water to extract the plants essences and nutrients. One can also infuse their own thoughts and energies into the potion through stirring. Think of the spoon as a wand.
With all that being said, does anyone have any helpful links on kitchen witchery? I have tried doing some research on here, but I haven't found anything informative. Also, from what I have got from this thread, my best place to start would be studying herbalism and healing subjects?
A kitchen witch is one that incorporates magical workings into the activities associated with the kitchen. This includes but is not limited to cooking, baking, and cleaning. Through the use of herbs, essential oils, common kitchen supplies such as; salt, baking soda, vinegar, etc and other magical tools which are often kitchen utensils, a kitchen witch imbibes their daily activities with magical energy. One may "stir in their love" as they mix ingredients, chant while a tea is steeping, as well as cleanse and banish negativity as they clean the home.
Oh, it turns out I already practices some kitchen witchery, then! Thank you all for your help, and I am still open to any other pieces of information/advice.
