This was a question I originally answered on a Facebook group. It is by no means extensive, and I will return to add/ edit later. Without further ado, Rustbelt Bruja’s Potions 101.
Brews - Water or alcohol based. Think teas, Florida water, and colognes. Can be ingested or applied to the skin given the ingredients you use, used in a spray bottle, or used as a floor/wall wash. When making a brew, boil the ingredients of your potion in water and strain into your container of choice. You don’t need much, as you’ll want to add alcohol (grain alcohol, vodka, or florida water) to any brew you don’t plan on drinking or refriderating to keep it fresh.
Oils - Oil based, chose an oil that works for the use you want. For example, if I’m doing a love oil I’ll use jojoba or coconut oil because I apply it to my skin. For anointing oils, I use olive oil. Can be used on the skin, in lotions, or anointing. For best results, store in dark colored jars, especially if herbs are still floating around in the oil.
