Recently came upon what I have found to be a very effective enema. . . . . Bar of Kirk's Castile soap that I leaved in a small container of filtered water and it turns into a very thick solution (2 ounces) with a ( 1/2 ounce) of Dr. Wood's Black Soap with Shea butter. Easy going in and the results are excellent and fast. In addition, once expulsion is done there are few after effects.
This might be to strong for some folks but I use enemas as part of a bowel program and need a potent mix. Sadly I can no longer find any of the medical grade castile packets.
I have tried the Dr. Bonner's but I just can't deal with the fragrances and the Baby Mild just isn't strong enough.
