A parasite cleanse is composed of a combination of herbs that kill off or drive parasites out of the body, for example black walnut hulls based formulas. A liver cleanse is composed of herbs and other supplements that detoxify the liver, for example, milk thistle based formulas. You can also try to aid the liver without cleansing it with herbs and supplements that act as antioxidants specific to the liver, such as alpha lipoic acid and wheat grass (an absorbable source of glutathione). A liver cleanse is more likely to wash out medication. If you take a probiotic for replenishing the system it has to be taken for awhile, and should be a good multi-spectrum one from the refrigerated section of the best health food store in your area. But that doesn't mean you'll notice anything if that's not truly the source of your problems or if your colony is intact.
Medication shouldn't be a problem. Currently, I'm only taking one prescription medication an I don't have to take it every day. I've tried taking probiotics, but it didn't help. What's the difference between a liver cleanse and a parasite cleanse? Can I do both at the same time?
Only if you have some reason to believe any of these is caused by parasites would a parasite cleanse help, and none of them appear to have that connection. I'm also assuming you're on medication or several medications, so cleansing can be problematic, as it can also cleanse out the medication. I would think a liver cleanse would be more appropriate, but again, it cleanses out medications. You might want to look up a gastroenterologist who is up on the new thinking of how important beneficial organisms such as probiotics are. Some are even doing fecal transplants to get the system back to normal colonization. If you can find one who is up on this they might be able to tell you if there's any connection that's been found between what you're suffering and either parasites or a beneficial organism imbalance, which what you call SIBO seems to be reflective of.
