"Detox," "cleanse," "natural" and "purify" are the words that sell natural colon cleaning remedies. They sound like a promise, but on their own they tell you very little. Two products can carry the same word on the front and share almost nothing else.
Two separate things are worth checking. One is whether cleaning out the colon does anything for general health. The other is what a product carrying those words actually contains.
What the evidence says about colon cleansing
The clearest answer comes from a systematic review in the American Journal of Gastroenterology (Acosta and Cash, 2009). The authors searched both the conventional and the complementary and alternative medicine literature. They found no methodologically rigorous controlled trials supporting colonic cleansing for general health promotion. They did find multiple case reports and case series describing its adverse effects, and concluded that the practice cannot be recommended. The review is from 2009, so it describes the evidence up to that point.
"Natural" is not a safety rating
The US National Center for Complementary and Integrative Health (NCCIH) puts it plainly: "natural" does not always mean safer or better for your health. One example it gives is kava, a plant often used as a supplement for anxiety, which may be associated with severe liver damage. NCCIH also points out that an herbal supplement may contain dozens of chemical compounds, and not all of its ingredients may be known.
That is why the word on the front matters less than the list on the back. If a product describes its contents only as a "cleansing complex" or "detox blend," the word on the front is doing more work than the contents can back up.
Turn the packet over
The ingredient list is the useful part of the label. On UK food labelling, the NHS explains that pre-packed foods must list their ingredients in descending order of weight, so the main ingredients always come first. Read that way, a list tells you far more than a headline word does.
Quantity claims deserve the same scrutiny. "Made with natural ingredients" says nothing about how much of each one is in there. The front panel shows what the seller wants you to read first. The back shows what you are buying.
What actually helps a slow bowel
For a slow bowel, the NHS page on constipation starts with diet and routine rather than products. It suggests fruits that contain sorbitol, such as apples, apricots, grapes (and raisins), raspberries and strawberries. It also advises drinking plenty of fluids, increasing fibre gradually and adding some wheat bran, oats or linseed. If those changes don't help, a pharmacist can suggest a laxative, and the NHS says laxatives should only be used for a short time.
Food-based approaches have some trial evidence. A 2026 network meta-analysis of 19 randomised controlled trials in functional constipation (Mou et al., American Journal of Clinical Nutrition) found fruit-based foods better than fibre supplements and placebo for how often people went, with moderate certainty. The abstract does not say which fruits were tested.
Dates carry a useful amount of fibre. USDA FoodData Central gives Deglet Noor dates 8.0g of dietary fibre per 100g. For more on fitting fibre into a normal week, see our higher-fibre diet plan.
The NHS also lists signs that need a GP rather than a home remedy: constipation that isn't getting better with treatment, blood in your poo, weight loss without trying, or sudden changes in your bowel habits.
A simple comparison point
Plain dried dates make a fair benchmark for any "natural" snack or cleanse. A packet of plain dates should list a single ingredient: dates. If anything else has been added, it should appear on that list too.
