The BF&C 'recipe' has been posted (several times, if I'm not mistaken).
Here's how we make it:
Add whatever type of organic oil you choose to pre-mixed BF&C herbs (c/s, not powdered), then let sit several days to soften the herbs (herbs will swell)...keeping the temperature at around 90-100 degrees F (we use the food dehydrator). Shake several times daily. Then macerate the herbs in VitaMix (or really good blender) and put back in the jar, and continue shaking several times daily for a minimum of 2 weeks, keeping the temperature at 90-100 degrees 24/7. Strain/press through organic muslin or other natural fiber.
It should be started on a new moon and strained/pressed on a full moon.
It is IMPERATIVE to shake the jar several times daily (MINIMUM). We shake ours around 10-15 times daily.
