Purely Earth Healing Bentonite Clay Food Grade


Purely Earth’s clay is an effective tool used for the management of eczema, psoriasis, rashes, hives, bites, difficult wounds, ulcers, reflux, indigestion, severe bruising, some fungal conditions and more.

You can use a clay bath for:

Eczema, itchy skin issues that cover more than a small area

To help remove chemicals and metals from the body during a detoxification program

To help reduce chemical rashes and reactions to chemical solvents and products

To help provide relief from chicken pox itching

To help reduce histamine in the skin – hives, allergic skin conditions

To help with the control of secondary infections on the skin which are common in eczema and other open skin conditions

To reduce lymphatic congestion and swelling

To reduce the impact of chemotherapy without interfering with the drug action – reduces body smell and the degree of side effects

To help manage lymphatic congestion in areas of the body where lymph nodes have been damaged or removed

To provide relief from aches and pains – foot baths for tired, sore and aching feet, full baths for conditions which affect more than the feet

Making a Clay Bath

  • Pour hot water into a bath.
  • Take 1 cup of Purely Earth Clay for an adult or ½ a cup for a small child’s bath and sprinkle it over the water using a whisk to mix it in as you go. It may take 5-10 minutes of whisking to disperse into the water and it will be clumpy to start.
  • Make sure the water is not too hot before climbing in.
  • For adults, soak your body for 30-60 minutes in the bath using your hands and feet to agitate the clay from time to time. Use the time to relax and switch off. Children are easily entertained with bath toys and try to keep them in the water for a good 30 minutes unless they are younger than 3 months in which case 10 minutes is recommended.
  • Do 1 bath daily for the first 10 – 14 days. Then do 2-3 baths per week depending on the condition and how it responds. You may need to do this for another 2-3 months.
  • After this, 1 bath each week as a maintenance is recommended as a preventative and general detoxification tool.
  • NB: For people who are very toxic, very congested or frail, start with a cooler (but still warm and pleasant) bath temperature and use a 1/2 cup of clay. Limit the first few baths to 15 minutes each time and gradually build up the amount of clay and the length of time in the bath over the course of a month. Start with 1 bath every 2-3 days.
  • We recommend sipping a glass of water with Endura Electrolytes in it while you are in the bath. This will prevent dizziness or a feeling light-headedness. This can be given to small children in a sipper cup.
  • After leaving the bath you may want to shower off very briefly, but this is optional.
  • If you do not have a bath, use the clay as a pack and follow the packing instruction. Pack the body in sections, doing a different section each day. For example start at the feet on the first day. The next day do one leg. The day after, do the other leg. Then move to the torso and so on. Do this until every part of the body has been packed 4 times. This takes longer, but it still works.
  • Alternatively, you can use a combination of sitz baths (tubs or buckets you can sit your bottom into) and foot baths intermixed with packing. The big flexi-tubs from The Warehouse work well for this.

The cation exchange capacity (CEC) is the measure of a clay’s ability to absorb and the higher the CEC, the better the clay will be at drawing and holding waste. A good bentonite clay should have at least an 80-90 CEC. The CEC of Purely Earth’s clay is significantly higher at 104 and it is unusual to find a clay with a CEC this high. To our knowledge, Purely Earth Clay has the highest CEC of all the clays available in New Zealand and possibly world-wide.

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 feld spar, quartz or other mineral compounds and contaminants. A 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 Australian Food Safety Standards and carries a Food Chemical Codex IV certification.
