Sure there are other sources for recipes in tincture making, order the videos from Sam Biser. You’ll get the recipes and instructions by Dr. Schulze himself. Or better yet, order the Dr. Schulze videos directly from Dr. Schulze .
After studying the videos for years, I’ve learned that there are more questions than answers in the videos and manuals. I would suggest that after you get the videos and study them, you find someone that is making the formulas and compare notes. Together, you will find some amazing answers.
