Put your gloves on because cayenne peppers are pretty hot.
Fill a quarter of the glass bottle with cayenne pepper powder and put enough alcohol to cover the powder. If possible, do this on the first day of a New Moon.
Blend a few fresh cayenne peppers, and add enough alcohol so it gets a sauce-like texture.
Add the mixture to the bottle which should now be 3/4 full.
Fill the bottle to the top with alcohol and close it well. Shake it several times during the day.
Leave the tincture until the next New Moon (after 28 – 29 days), and strain it using a gauze. Keep it in a dark bottle.
If you want to have a very strong tincture, strain it after 3 months.
Close the bottle and store it in a dry and dark place. It doesn’t spoil, so you can use it as long as you want.
