Digging through my herbal recipes I came across a simple recipe for an acne cream, my son has had some trouble with acne over the last year and we needed something topical, the first time he used it we noticed a difference the next morning. He's used it about four times now and each time his face looks much clearer and the blackheads have started clearing up.
Herbal Acne Cream
1/2 tsp Oregon Grape Root Powder OR Goldenseal Powder
1/2 tsp bentonite clay
6 or more drops tea tree essential oil
6 or more drops grapefruit seed extract
Mix all in a small bowl to form a paste. If it's too runny add a little more clay, if it's too thick add more liquid. Apply to blemishes at night or at a time that you don't have to leave home for a couple of hours. Rinse with warm water. The mixture is a dark green color and works wonderfully, give it a try.
