I have had a lifetime of interest in health of all areas, and created an herbal vinegar based "skin-tonic" that has been healing all sorts of skin ailments. I love to go foraging and hiking and I LOVE GOING TO THESE CLASSES! What a blessing Mr. Alfs is, I have been so impressed by his knowledge of herbal remedies and his dedication to prove the healing properties of herbs through scientific lab studies. 100% recommend this program!
