The Takesumi


1) Appearance and sound :
The appearance must be black with metallic or iridescent reflections. The tinkling of 2 bamboo coals together should give off a metallic sound.

2) Electrical conductor (multimeter test) or bulb :
When the Takesumi is cooked at high temperature or activated (between 800° to 1000°), it conducts electricity. All you need is a multimeter or an electric lamp bulb with 2 ends connected with electric wires. The indicator piece conducts electricity and the bulb lights up if the carbon is activated and of good quality.

3) Adsorbing chemical particles present in the water (contaminated water glass test) :
2 test glasses filled with chemical particles and dyes are placed side by side. In one, pieces of bamboo charcoal were placed. After a few hours, the liquid in the glass that has received the takesumi clears up because it has adsorbed the chemicals. The other remains yellow (dye).

4) Reduction of electromagnetic waves (testing of the electromagnetic wave measuring device) :
The takesumi is placed close to the electronic device in question (laptop, computer...), the measurement before and after shows a decrease in V/m.

 An ancestral Japanese handcrafts

In the Middle Ages, each village had its own master takesumi burner. The population used it daily to purify water, reduce the acidity of food and cure infections and intoxications. It is no coincidence that life expectancy in these regions was higher than average at the time.

Today, Takesumi is still produced in a clay oven, according to the ancestral Japanese know-how. Moso or tiger bamboo wood is burnt for 3 days at 800° to 1000°. Burning at very high temperatures makes the coal of very high quality. The production of Takesumi requires one month's work. It takes 10 days to 2 weeks to reach an optimal temperature for cooking, then another 10 days to 2 weeks for cooling.

Special features of Takesumi

Bamboo charcoal, called black diamond, is one of the rare ingredients with a very wide range of uses.

Its fine, smooth bark and ultra-porous pulp make it an excellent adsorber. Like a sponge, it adsorbs and retains 3 to 4 times more air and water pollutants than conventional activated carbon. Its adsorption surface area is 3000m2/gram, which gives it its incredible depolluting virtues.

Takesumi contains many minerals: potassium, calcium, silicic acid... It also has a negative charge (negative ion) which naturally attracts toxic particles to it.

In 2004, a study carried out by the Kagoshima Forestry Division (Japan) showed that the PH of water purified with Takesumi changes from acid to alkaline. The study also showed that the adsorption of volatile organic compounds was more efficient when the carbon was carbonised at over 800°.

The bamboo charcoal powder is of impeccable quality. Its grains are extremely fine and non-abrasive. They measure between 5 and 10 microns. 

1001 applications

1. Purify and mineralise the water: takesumi, neutralises the taste of chlorine, softens the water, absorbs the polluting residues left in the water while discharging its minerals. Place a stick of takesumi or a bag of powder in a glass or pitcher. Let it stand overnight so that the takesumi attracts pollutants to itself and mineralizes the water.

2. Regulate humidity: Instead of using chemical moisture absorbers, place a small bag or a few pieces of takesumi in places where you want to control humidity, especially during the rainy season: in a cupboard, drawers or shoe wardrobe.

3. Relieve the digestive and intestinal system: charcoal is known to absorb gas and relieve difficult digestion.

4. Deodorise: Bamboo charcoal can also absorb odours. Whether in the fridge, in a small space, in cupboards, shoes... You can place small bags of takesumi wherever you want to neutralise bad smells.

5. Keep fruit and vegetables fresh for longer thanks to takesumi. Placed in the vegetable crisper of the fridge, it allows fruit and vegetables to be stored for 2 to 3 days longer.

6. Cleaning food: the absorbent properties of takesumi attract bacteria and pesticides to it. Soak fruit, vegetables or other foods in a container with a bag or piece of takesumi for several hours.

7. Natural food colouring and DIY make-up: takesumi is odourless and tasteless, it is used by great chefs to add a touch of colour to food. It can also be used as a natural pigment for make-up.

8. Reducing electromagnetic waves: intense exposure to low frequencies can be harmful to our health. Placing a piece of takesumi near your electronic devices will reduce the waves and protect you. For electro-sensitive people, it is recommended that you wear a piece of takesumi on you.

9. Get healthy skin: takesumi attracts and absorbs toxins and impurities embedded in the skin. Applied to the skin or mixed with daily care products, it will naturally remove the micro-particles accumulated in the pores.

10. To cleanse the body: used in a "detox" cure, takesumi cleanses the body by adsorption on the intestinal, renal and hepatic systems (elimination of toxins such as nicotine, food additives, drug residues, chemical compounds) without eliminating useful nutrients such as vitamins, trace elements, minerals or amino acids. For a one-week cure, mix one teaspoon of takesumi powder in a glass of water. Drink on an empty stomach.

Caution: Activated charcoal cures last on average 7 to 14 days. It is always advisable to seek medical advice as part of a course of treatment. If you are taking medication or other treatments at the same time, or if you have constipation or digestive problems, the advice of a doctor is essential.

11. In the garden: takesumi has antifungal and antibacterial actions, particularly effective when used preventively. It also has fertilising virtues, improving the physical, biological and chemical properties of the soil.
