'Just a quick reminder that ALL "laxatives" can be "addicting". Anytime, with any substance, that we induce bowel activity without treating the root cause of the lack of bowel activity, we're usually allowing the original cause to progress & worsen. This is particularly true with otc & pharmaceutical laxatives - particularly those that are magnesium based. The magnsesium draws water from the bloodstream into the intestines, producing bowel action...but this type of action doesn't require any squeezing or constricting of the peristaltic muscles in the intestines...so they grow weaker. The stimulant herbs (senna, cascara, turkey rhubarb and the like) are typically villainized as being the type of laxative that is the worst . These herbs actually cause the intestines to sqeeze & contract (which is why many people experiencecramping). This squeezing & contracting helps exercise the peristaltic muscles and helps to prevent 'laxative addiction'. Of course, lack of herbs or otcs/pharmaceuticals is not the cause of constipation, but lack of bile flow (bile induces peristalsis in a very similar manner to the laxative herbs) and a stretched, congested colon that's lost elasticity & 'squeezing action' are typically at the root cause. Here's a post with more information on this topic: http://curezone.com/forums/fm.asp?i=1408157#i Sadly, we find (many times) that even herbalists believe & perpetrate the lies about herbs from the medical/scientific community :(
Both Dr. Schulzes IF#1 and Dr. Christophers LBB contain small amounts of several different 'laxative herbs' as well as herbs that stimulate the liver and have other benefits. Check out the herbs and actions in IF#1 and how they work together http://curezone.com/schulze/handbook/intestinal.asp#1
Regarding Miralax...YIKES. It'd be much safer to use ExLax or Milk of Magnesia (both DO induce laxative dependence, but at least they don't have the adverse-effect profile shown below).
'Hopes this information helps :)
The data below is taken from a pay-site for practitioners called eHealthMe (I pay $100 yearly to access this data). This site compiles ACTUAL data from actual adverse effects reported directly to the FDA. The FDA officially states that only 1 in 100 adverse effects are ever reported, so you can multiply the numbers in the data below by 100 for a clear picture.
Always note that the adverse effects of these low-dose poisons that are commonly listed on the package inserts (and elsewhere on the internet) are NOT even close to a clear picture. Clinical trials done for only 4-8 weeks with a very select group of people. A few weeks is not long enough to ascertain the negative effects of low dose poisons (think alcohol...if a 4-8 week trial was done on potential liver damage of drinking a 6-pack nightly, the results would likely read 'no adverse liver effects' or very slight. But a clinical trial of drinking a six-pack nightly for 4-8 YEARS...would produce an entirely different picture). Adverse reactions are always minimized by the pharmaceutical cartel (and many times patients that exhibit symptoms are 'dropped' from the clinical trials for 'other' reasons).
The results below (when the numbers are multiplied by 100) give a fairly clear picture of the adverse effects...but it doesn't show the myriad of negative events that happen within the body to bring about the symptoms.
