Our guidance — for short-term use. This formula contains rhubarb root, aloe vera leaf and barberry bark, which are traditional stimulant laxative botanicals. We recommend occasional short-term use rather than daily long-term use. Avoid during pregnancy or breastfeeding, if under 18, or if you have a bowel obstruction, undiagnosed abdominal pain or inflammatory bowel disease. See your GP if constipation persists beyond a few days.
Some constipation doesn't respond to fibre. When bulk-forming approaches have already failed, a stimulant botanical formula is the next step — and BioBlast is a strong one. Originally based on a formula by American master herbalist Dr John R. Christopher, it combines purgative botanicals with carminatives — herbs that reduce griping — plus sugar beet fibre carrying an EU-authorised faecal bulk claim. It has long been a favourite with colonic hydrotherapy clinics.
Why the Carminatives Matter
Stimulant laxative herbs work, but taken alone they commonly cause cramping and griping. The traditional herbalist's answer is to pair them with carminatives — ginger root, cayenne, dandelion — which ease the spasm while the purgatives do their work. That pairing is the design principle behind this formula, and it's why it is used by practitioners rather than sold purely as a retail laxative.
How Other UK Constipation Products Compare
Senokot — senna, pharmacy standard. A licensed senna-based stimulant laxative. Effective and well understood, but a single-herb approach without carminatives or fibre, and no halal certification.
Dulcolax — bisacodyl, pharmaceutical. A synthetic stimulant laxative rather than a botanical formula. Reliable, and appropriate for many people, but not a herbal product.
Fybogel / psyllium — bulk-forming, gentler. The sensible first-line option and considerably gentler. If bulk-forming fibre has worked for you, use that rather than a stimulant formula — BioSlim is our psyllium and glucomannan option.
What's in Every Capsule
EU-authorised claim:
-
Sugar beet fibre — 45mg · contributes to an increase in faecal bulk · works two ways: the insoluble components absorb water in the large intestine, while the soluble components are fermented by gut bacteria, increasing bacterial mass
Dietary fibre — 172mg per capsule, of which capsule shell 120mg, sugar beet fibre 45mg and glucomannan 7mg.
The botanical blend:
-
Rhubarb root powder and extract (Rheum palmatum) · the lead botanical · traditional purgative used in both Western and Chinese herbal medicine
-
Glucomannan powder (Amorphophallus konjac) · soluble fibre that absorbs many times its weight in water
-
Cayenne fruit pepper powder · carminative · traditionally used to reduce griping
-
Dandelion root extract (Taraxacum officinale) · traditional bitter digestive botanical
-
Aloe vera 200x powder (Aloe barbadensis) · concentrated leaf extract · traditional purgative
-
Ginger root extract (Zingiber officinale) · carminative · one of the best-established anti-spasmodic digestive herbs
-
Nettle leaf extract (Urtica dioica) · traditional mineral-rich botanical
-
Barberry bark extract (Berberis vulgaris) · berberine-containing traditional bitter
-
Black garlic extract (Allium sativum) · aged garlic, milder than raw

How to Take It
Take 1 or 2 capsules, one to three times per day, or as advised. Start with the lowest dose and increase only if needed. Take with plenty of water.
This is not a daily supplement. Stimulant laxative botanicals are for short-term use while you address the underlying cause. For ongoing bowel regularity, bulk-forming fibre is the appropriate long-term approach — BioSlim for psyllium and glucomannan, and BioTic 4 Billion to support gut flora afterwards.
Is This You?
- Fibre and gentler approaches haven't shifted things and you need something stronger, short term
- You're preparing for or recovering from colonic hydrotherapy — this formula is widely used by practitioners
- You'd rather have a botanical formula with carminatives than a single stimulant herb that causes cramping
- You need halal and kosher approved bowel support
- You are not pregnant, breastfeeding, under 18, or managing a bowel condition

Questions We Get Asked
How long can I take this for?
Short term only — days rather than weeks, and not as a daily supplement. Stimulant laxative botanicals such as rhubarb, aloe and barberry are appropriate for occasional use while you address the underlying cause. Prolonged use of stimulant laxatives of any kind is associated with reduced bowel responsiveness over time. If constipation persists beyond a few days, speak to your GP rather than increasing the dose.
Does it contain senna?
No. BioBlast contains no senna — its purgative botanicals are rhubarb root, aloe vera leaf and barberry bark. What sets it apart from single-herb laxatives is the inclusion of carminatives, ginger and cayenne, traditionally used to reduce the griping that stimulant laxatives commonly cause. It is still a stimulant formula and should be treated as one.
Who should not take it?
We'd advise against use during pregnancy or breastfeeding, if you are under 18, or if you have a bowel obstruction, abdominal pain of unknown cause, inflammatory bowel disease, or are dehydrated. Speak to your GP first if you take prescription medication, particularly diuretics, heart medication or corticosteroids, as laxatives can affect potassium levels.
What should I use for ongoing regularity instead?
Bulk-forming fibre, taken with plenty of water. BioSlim combines psyllium, glucomannan and sugar beet fibre with live cultures for daily use. Stimulant formulas like BioBlast are for the occasions when that hasn't been enough.
Food supplements should not replace a varied diet or healthy lifestyle. For short-term occasional use only. Not recommended during pregnancy or breastfeeding, or for anyone under 18. Do not use if you have a bowel obstruction, undiagnosed abdominal pain or inflammatory bowel disease. Consult your GP if constipation persists or if you take prescription medication.
