Bentonite clay, often referred to as Montmorillonite clay, is a naturally occurring fine-grained material derived from the geological weathering of volcanic ash. It is composed primarily of the mineral montmorillonite, an aluminum phyllosilicate, which contributes to its unique properties. Its mechanism of action involves both adsorption and absorption, allowing it to attract and bind to other substances. Bentonite clay particles possess a strong negative electrical charge, enabling them to attract positively charged ions found in impurities and heavy metals. When hydrated, the clay rapidly swells, acting like a highly porous sponge to draw in and sequester material within its structure.
Preparing Bentonite Clay for Use
Proper preparation is necessary to activate the clay’s properties and maintain its efficacy. The dry, powdered clay requires mixing with water or another liquid, such as apple cider vinegar, to form a paste or slurry. This hydration causes the clay to swell and develop its charged, sponge-like structure, maximizing its capacity for binding substances.
It is crucial to use non-metal utensils and containers, such as those made of glass, wood, or plastic, when mixing bentonite clay. The clay’s strong negative charge can react with metal, potentially reducing the effectiveness of its drawing properties. Contact with metal can alter the clay’s ionization, which is central to its ability to attract and bind impurities.
Store the dry clay powder in an airtight container away from moisture to preserve its shelf life. When using the prepared clay, remember that the clay absorbs moisture. Ensure you maintain adequate hydration by drinking plenty of water throughout the day.
How to Apply Bentonite Clay Topically
Topical application is a common and effective way to use bentonite clay, primarily for drawing impurities from the skin. For a facial or body mask, combine one part bentonite clay with one to two parts water or apple cider vinegar in a non-metal bowl. Apple cider vinegar is often favored for facial masks as it helps create a smoother paste and balance the skin’s pH. Apply the mixture in a thick layer, carefully avoiding the sensitive areas around the eyes and lips.
The duration of the mask depends on your skin type. For sensitive or dry skin, leave the mask on for only five to eight minutes, ensuring it does not fully dry. Those with oily or less sensitive skin can tolerate a longer application of 10 to 20 minutes, or until the mask feels tight. After rinsing with warm water, some redness is common and should subside within 30 minutes.
For a detox bath, add about one-half cup of bentonite clay to warm bathwater and soak for 20 to 30 minutes. It is helpful to first mix the clay with a few cups of warm water in a non-metal bowl to dissolve any clumps before adding the slurry to the bath.
Poultice Application
For localized issues like insect bites or minor inflammation, a poultice can be made by creating a thick paste of clay and water. Apply a liberal amount of this paste directly to the affected area or on a piece of gauze, and cover it with a compress. Leave it on for several hours, changing it as needed.
Always perform a patch test on a small, inconspicuous area of skin before applying the clay to your face or a large area of your body. This precaution helps check for any potential allergic reactions or excessive sensitivity. If you experience irritation, discomfort, or excessive dryness, discontinue the topical use.
Guidelines for Internal Use and Consumption
The internal use of bentonite clay is practiced by some for detoxification, but it requires careful consideration and consultation with a healthcare provider. To prepare the clay for consumption, mix approximately one-half to one teaspoon of food-grade bentonite clay powder with a full glass of water. Stir the mixture thoroughly, allowing a few minutes for the clay to fully hydrate before drinking.
It is recommended to consume the clay slurry on an empty stomach, such as first thing in the morning, or at least one hour before or after eating. The clay’s strong absorption properties can lead to constipation or, in rare cases, intestinal obstruction if not taken with sufficient fluid. It is paramount to drink ample water throughout the day when ingesting the clay.
A crucial safety warning involves the clay’s potential to interfere with the absorption of medications and nutritional supplements. Because bentonite clay binds to substances in the digestive tract, it can reduce the effectiveness of oral medications, including certain antibiotics, heart medications, and blood thinners. To mitigate this risk, a time gap of at least two hours should be maintained between consuming the clay and taking any medication or supplement. Individuals who are pregnant, nursing, have existing health conditions, or are taking prescription medication must discuss internal use with a medical professional beforehand.
