Many bentonite clays are acid leached, heated or tampered with in some way. If being used in or on the body, it is essential to use a food-grade clay because this will have been tested for heavy metals and other contaminants. Purely Earth’s clay is untreated and in its natural state.

Sodium bentonite tends to be less drying to the skin than calcium bentonite, and because it has a higher absorption ability it tends to be a better “sink” for toxins.

A quality clay should be milled to a 44-micron particle size and should have a low contaminant level. There are a number of clays on the market that contain a significant amount of feldspar, quartz or other mineral compounds and contaminants. Quality bentonite clay should be over 90% pure bentonite and should meet food-grade standards. Purely Earth Clay meets these specs.

Both food-grade calcium and sodium bentonite may be used internally. Sodium bentonite is the more active of the two clay types. Improved bowel frequency, better stool formation and decreased gas and odour are some of the benefits experienced by most people who use our clay internally.

Purely Earth’s Clay is one the best quality clays in the world. It meets the Australian Food Safety Standards and carries a Food Chemical Codex IV certification.

When the clay is made up you can use internally or as a face mask, or for clay packing.


The following information is not intended to diagnose any condition or to replace the advice of your doctor.  

Purely Earth Clay is helpful as a cleanser of the intestines and may assist with removing microbial infections from the bowel. It can help significantly with digestive upsets, gut infections, gas, reflux and bloating and will help to absorb toxic waste from the bowel.

You can use clay internally to:

  • Reduce reflux and indigestion
  • Reduce bloating and gas
  • After food poisoning to help with detoxifying the bowel
  • To assist with metal and chemical removal through the bowel
  • To improve bowel function and the intestinal microbial balance
  • To assist with the healing of gastric ulcers
  • To reduce irritable bowel symptoms

To mix up the clay:

  • Do not try to mix Purely Earth Clay into a glass of water – it will not dissolve easily. It is best to make it into a “gel” as outlined below.
  • Do not encapsulate the clay. It needs to be made into a gel using water to activate it. It will swell when water is added and taking it in capsule form may result in the clay forming a clump in your gastro-tract. This may cause constipation and will not allow the clay to do its job correctly.
  • Put 1 cup of warm water into a bowl or container and add around 20 gm of clay powder, sprinkling it over the water surface. It will be quite clumpy to start – mix in as best as you can and leave it to sit for half an hour. Come back and use either a hand held wand blender or a hand whisk to blend to a smooth runny paste. If it is too runny, add a bit more clay powder. If it is too thick, add a little more water. It should look like a runny yoghurt.
  • You can make up a container-full and keep the unused hydrated clay in and air-tight container in the fridge for up to 3 months. This way you can help yourself to the ready made clay when you need it. Or you can use as a face mask.

To take the clay:

  • Start by taking with 1 tsp of paste directly on to the tongue and swallow with some water on an empty stomach. It is easy to get down as it is soft and has little flavour.
  • Take the clay 1-2 hours away from medications and supplements as it may reduce their absorption.
  • Always drink plenty of water through the day when using clay internally.
  • After a couple of days you can increase to 1 tsp 2 x daily. Always start with a small amount and see how that goes over a few days before trying a higher dose.
  • If you experience a slowing of your bowels, check your water intake first. If it continues to be a problem, discontinue use. (This is unusual and generally only happens if our instruction is not being followed; most people notice an improvement in their bowel function).
  • Our clay may be used internally while breastfeeding, but due to regulations we recommend avoidance in pregnancy.

Purely Earth Clay is one of the best quality clays in the world and is used in the food industry for refining purposes. As a result it has to meet food industry standards and is certified as meeting Australian food safety standards Food Chemical Codex IV. We are required to mention that if you choose to use clay internally it must be on the understanding that it is at your own risk, even though bentonite clay is generally recognised as safe. We cannot be held responsible for the misuse of our clay or the failure of people to read and correctly interpret the instructions for its use.
