Simple, Effective, Wonderful - Traditional Applications of Medicinal Clay
Medicinal clay offers a variety of therapeutic and cosmetic uses that can enhance your wellness routine.
Certain types of clay can be used externally and internally.
For external use, clay is mixed with warm water, herbal tea, rose water, or apple cider vinegar to form a smooth paste to be applied to the whole body as in Hungarian mud wraps or prepared in poultices for application to specific parts of the body as in French Green Clay face masks. Added warmth opens the pores of the skin and helps the interaction of the clay with the body.
Ingesting clay can do wonders for your health! Internally it is used to detox the intestines and the colon, and thus the entire body. Clay reduces inflammation by binding toxins and heavy metals as well as reducing bacterial and fungal overgrowth. While the beneficial detox properties are linked to the impressive binding capacity of clay, it also supplies up to 75 important trace minerals to the body (depending on the type of clay).

Your Spa at Home 
Clay works fantastic for facial masks, which are easy to prepare, and praised for their exfoliating, purifying properties. Clay masks absorb excess oil and draw impurities out from your skin. They help heal rashes and acne.
Types of medicinal clay
French Green Clay is a 100% natural form of illite clay. It is a combination of volcanic matter, decomposed plant substances and minerals. It is purifying and used for its high mineral content in beauty and wellness applications, primarily recommended for oily skin or a normal/oily skin combination.
Moroccan red clay, Rhassoul has a long tradition in Hammam baths. This clay contains iron and is used to heal acne. Rhassoul clay is a mineral-rich, natural brown clay from Morocco's Atlas Mountains, renowned for absorbing impurities and excess oil. It improves skin clarity and texture by acting as a gentle cleanser and exfoliant. Contains high levels of silica, magnesium, potassium, and calcium thus nourishing the skin and scalp. 
 It is gentle enough to be suitable for sensitive, dry, or mature skin.
Bentonite clay is found in the Western United States, and Luvos loess is a traditional, therapeutically used clay from Germany. Both are safe for use on all skin types. 
Fuller’s earth is a very fine grayish colored powder derived from algae, chock full of minerals and very absorbing.

Keep in mind that while clay facial masks are the right choice for oily and acne-prone skin as well as skin that has been exposed to environmental pollutants or tends to have many blackheads, this same quality can be too much for dry skin. When using a clay mask on dry skin, follow up with a moisturizer and thin layer of face oil (rosehip, sesame, jojoba, or argan oils are nourishing options).
How to prepare a clay mask at home
Mix the powder with warm water, rose water, or herbal tea to create a smooth, thick paste.
Apply to the face, let it dry for 10-15 minutes, and rinse off.
In a small bowl, mix 2 tablespoons of the clay with about 3 tablespoons of liquid. Depending on your skin type use spring water or rose water for normal skin, or witch hazel and orange blossom water if your skin is oily. For dry and sensitive skin it is recommended to substitute water with sesame, olive, or almond oil. If you are suffering from acne, add 1 tablespoon apple cider to the mix. The consistency should be thick and cream-like, not runny. If you added too much of the liquid just stir in a little bit more clay. Apply the mask to your cleaned face and neck with your fingers or a make-up sponge. Avoid the eye area. Leave on for 15 to 30 minutes. Once the mask is dry, rinse off with lukewarm water and apply moisturizer. Your skin will glow with vibrant good health.

Wellness Uses of Medicinal Clay
Medicinal clay provides an affordable and natural yet effective remedy against diarrhea, heartburn, and acid-related stomach pain due to its ability to bind excess bile acids, and cholesterol. Simply stir 1 teaspoon of either bentonite or green clay into 8 oz. of water, and drink on an empty stomach in the morning. Wait for 30 minutes before eating anything. Do this as a cure fore 21 days in a row. Repeat 3 to 4 times per year. Or use as needed for treatment of acute ailments.
Bentonite, montmorillonite, and illite have been proven to be antifungal including toxic and carcinogenic infections such as Aflatoxicosis, and effective against yeast infections including Candida albicans. Eating or drinking healing earth can be used to cleanse the body from heavy metals including lead, cadmium, and mercury. Another property of immense benefit is the antibacterial effect of bentonite and green clays. In several scientific studies conducted in France and Arizona, the clays have been found to be highly effective against E. coli, pseudomonas, salmonella, and even the dreaded “superbug” MRSA and the flesh-eating African bacteria buruli to name just a few. One side-effect to be considered before using clay internally is the inhibition of the body’s absorption of antibiotics, substitute hormones and heart medication by coating the digestive tract.  How is it possible that certain types of clay are so versatile and beneficial for human health?

Loess, bentonite, and green clay naturally form a negative charge when mixed with water. This negative charge creates a pulling effect called adsorption, drawing positively charged ions out of our cells – and it so happens that bacteria, heavy metals, and pesticides all have a positive ionic charge. Negatively charged ions stay untouched. One more amazing capability of clay that depends on its acting like a plus pole is the adsorption of radiation. A study performed by Duke University found that specific parts of the human DNA and RNA exposed to damaging gamma radiation recovered faster in persons that had eaten clay.

Luvos is a natural medicinal product made from glacial loess in Germany, rich in minerals and trace elements like silica, calcium, magnesium, copper, and zinc. It is used internally for heartburn and stomach issues, and externally for acne, inflammation, and skin issues. It acts as a natural binder for toxins, fats, and cholesterol. 
Applied to the skin, it reduces acne, blemishes, skin impurities, inflammation, muscle pain, and joint issues. It binds sebum and impurities, creating a suction effect that cleanses the skin and removes blackheads.
Because of its strong ability to bind other substances, it should be taken at least 2 hours before or after other medications.
Bentonite clay is a natural, absorbent aluminum phyllosilicate clay derived from volcanic ash, widely used for detoxifying skin, treating rashes, and in, for example, this Amazon product. It works via a negative electrical charge that adsorbs positively charged toxins, heavy metals, and impurities, functioning as a "magnet" for cleaning.
Skin Care: Used as a face mask to absorb excess oil, minimize pores, and treat acne.
Detoxification: Known for drawing out impurities and toxins from the skin.
Dermatitis Relief: Helps treat poison ivy, poison oak, and diaper dermatitis.
Mechanism: When mixed with water, it develops a negative charge, allowing it to attract toxins.

Often mixed with water or apple cider vinegar to create a paste for masks. It is recommended to use non-metal (wooden or plastic) utensils when mixing, as metal can reduce its effectiveness.
