Are herbal colon cleansers safe? A lot of times, it depends on who you ask. There are a number of herbal products on the market that claim to be easier, safer, and gentler on the body than chemical colon cleansers. However, the makers of chemical cleansers suggest that herbal colon cleansers are dangerous. It’s hard to know who to believe. In general, it appears that occasional use of colon products is safe, but there is further debate about whether such cleansing is beneficial. In cases like this, it’s hard to separate the marketing from the truth. The easiest thing to do is probably just eat more fiber, which has known health benefits and is substantially cheaper than buying colon cleansers.
