Hi, I'm just using a 50mil hypodermic syringe that was given to me by a vet for a horse. I have attached a piece of plastic tube to the end instead of a needle. This is not a proper enema. I read a post that someone that had bad Acne had cleared it with urine ememas, and I thought I would give it a try with what I had available as I have rosacea Acne which may be caused by candida. However one advantage of a small quantity is that the bowel keeps it in for longer before I gotta go. I'm sure there is someone reading your post that has more experience of this method and could give you more information. Good Luck. Love and Light, Deotima.
