Harker Herbals Intestinal Cleanse An important tonic in the Malcolm Harker range, Intestinal Cleanse is a gentle cleanse for the digestive tract to support healthy digestion, increased energy levels and discourage parasites, helping essential minerals and nutrients from foods to be absorbed into the bloodstream.  Harkers Herbals recommends taking Intestinal Cleanse four times a year for 7-14 days. Intestinal cleanse may also support microbial balance in the digestive tract.


  • Do not use during pregnancy. Short term use only – up to 6 weeks at a time. Caution if using Loop diuretic, Thiazide Diuretic or Warfarin medication. Consult your natural health practitioner if using these medications.
  • These tonics may affect absorption of antibiotics. It is recommended that the dose of tonic is taken at least 2 hours after antibiotics have been taken.
  • These tonics may affect blood clotting and blood sugar control. It is recommended that these tonics are not taken within 2 weeks of any surgical procedure.
  • Due to small amounts of iodine being present in all tonics, we recommend all tonics are contraindicated for hyperthyroidism (with or without prescribed medication) or any thyroid replacement medication (such as thyroxine).

Tastes terrible
04-11-2019 12:51:33
I purchased this thinking it sounded like something worth trying for my IBS upsets. I noted a few people said the taste was pretty awful but equally a few seemed to think it was fine so I figured I\'d give it a go. I had 5ml and swilled it in my mouth as it suggests and I honestly have to say I cannot describe how awful the taste was. I had to eat and drink several different things afterwards to get rid of the taste in my mouth and I felt nauseous for at least half an hour. Needless to say I could not take any more.\nI\'d just like to suggest others be wary of this when looking at purchasing this product.

Bought this on the basis of reviews saying it had a nice taste. Love the Harkers products so thought they\'d be right. OMG, the taste is disgusting! For a nano-second on your tongue it seemed OK, but then the bitterness hit and I had to get rid of the taste with a spoonful of manuka honey. Disappointed with a waste of money - I was going to give it to the whole family, but I won\'t traumatise them with it.

This is the best product I have found for IBS, I must have had nasty parasites and worms, did not see any. Digestion is working so much better, finally losing some weight, my skin is so much clearer, feeling like my old self again. Will use again. Recommend this product to anyone with digestion problems.

Brilliant product

Real top results after taking this product - all the intestinal tract feels lighter, digestion is faster and no bloating, cravings reduced to non-existent, losing weight. As to the taste, I understand it has medicinal use, so I accept it the way it is - and understand it is not meant to taste like chocolate cake. The results for me are more important then fantastic taste.

Magic formula

This arrived yesterday and I started slowly and easing to three doses today. My Bowels are finally moving, I have been constipated for days, due to meds. Although stool hard, I am not in pain. I can't believe the parasites as well. My gosh, I regularly worm myself and pets, but I've noticed lots of wee thread worms. I'm generally a healthy person who exercises all the time and eats healthy. I just can't believe I've had parasites. Just revolting; but better gone! I know I'll be feeling a million dollars by the end of the week!

great product

Love this product. It has sorted out a gut issue I was having - no idea if I had parasites or not, as, er, I didnt spot any! As for the taste, yes it is pretty awful - although my sister really likes it - but I found I got used to it. And it was worth it to get the end result.

I read lots of the reviews and thought this would be great! But if you are thinking of giving it to children like I had hoped, then NO it's not going to happen. So, I had it first and I nearly threw up, and the taste stays in your mouth. Thankful I didn't buy the big bottle! NOT RECOMMENDED FOR CHILDREN!

Amazing product

This is by far the best product I have EVER used for my health. After suffering from severe IBS for a number of years and often ending up in hospital with no diagnosis I decided to do a cleanse. I found this cleanse with not too many expectations but I couldn't believe the results. I took the highest dosage possible and used two 500ml bottles over a two week period and got rid of a large number of parasites and intestinal junk. Now I take a dosage every now and then when I have an IBS bout or gastritis and it relieves it right away. Couldn't recommend this product more.

Very effective

Cleanses the digestive system making for improved bowel motions. My husband who eats an average diet and drinks far too much beer (which causes diarrhoea every time he drinks it!) has had really good effect using this, his stools are now formed. My 3 year old takes it off the spoon, so surprised by that as it tastes very peppery and bitter. I suspect he has worms as he has been picking at his back side, he's not been doing this lately so I hope that means he's got rid of them. As for me, I'm not sure if I have cleared parasites as haven't seen anything. I don't feel a noticeable difference in energy or anything and my food intolerances are still there. I have just done 4 weeks but will give myself a break and do another 4 weeks soon. Liver support is a must while on this product.
