It's the caffeine I'm mostly concerned about as well.

According to this article from SAWilson's, the caffeine doesn't become absorbed:

" coffee enemas will not waste minerals and electrolytes because they have already been absorbed in the previous sections of the intestines. The coffee enema is safe even for people who are sensitive to caffeine because the coffee remains in the sigmoid colon, where it will not be absorbed, provided the proper amount is used and the enema bag is not place too high."

The same info is also mentioned elsewhere. I wonder how true it is. I'm going to keep looking into it.

I guess an important question to ask is this: What is the role of caffeine in coffee enemas?

EDIT:

The article mentions the purpose of caffeine. It looks like caffeine is the active ingredient in this therapy. There seems to be a contradiction here, though, about whether the caffeine is absorbed into the body or not.

Here:

"The coffee enema has been used for many years to detoxify the liver. It is a low-volume enema that remains only in the sigmoid colon. There is a duct between the sigmoid colon and the liver called the entero-hepatic circulation system. When the stool reaches this point, it contains many toxins, which are sent to the liver for detoxification. The coffee enema will increase the transit time in the bowel. The caffeine that is absorbed into the entero-hepatic system causes the liver ducts, including the bile ducts, to empty into the sigmoid colon and be eliminated. Releasing the toxins in the liver ducts, makes room for toxins from the body to enter the liver for detoxification. The alkaloids in the caffeine stimulate the production of glutathione-S-transferase, which is an enzyme that facilitates the liver detoxification pathways."

Here's the article - //www.curezone.org/art/read.asp?ID=28&db=5&C0=818

When doing a CE, you need to make sure that you keep the bag/bucket really low- even two feet may be too high. You want the coffee to enter very slowly. If it does quickly, you have more of a chance of it getting absorbed. It is supposed to be more like an "implant", not a high colonic.

Having said that, I would still try it in the morning, a weaker version first, and not at night in case you're sensitive and do absorb some of the caffeine.

Can someone please explain how to do a liver poultice on the outside of the body and how effective they are? Thanks
