By cooking mature stalks of bamboo at temperatures around 1000º C, the hardy plant undergoes thermal decomposition and turns into bamboo charcoal. This dark grey and seemingly inert end product actually has a surprising range of uses. Historically, the myriad applications of bamboo charcoal date back many centuries, millennia even. We can trace the oldest written record to the Ming Dynasty, 15th century.

Bamboo charcoals have more than 400 kinds of minerals and hundreds of medicinal benefits and effects for our health.
Similar to other forms of activated charcoal, bamboo charcoal is highly porous and capable of absorbing pollutants from both air and water. As such, bamboo charcoal also has the ability to absorb moisture in the air and balance indoor humidity levels, making it ideal to use during the rainy season.


Though takesumi has many uses, some possibilities include:

1. Purify drinking water

2. Control humidity – Instead of using chemical humidity absorbers, toss a small bag or a few pieces of takesumi in places you may want to control humidity, especially during the rainy season/summer, such as your closet, dresser drawers, or shoe cupboard.
If you use an electron microscope, you’ll see infinite numbers of extremely small micron-sized holes in the charcoal. This is the porosity. Because of that, 1 gram or just one pinch of charcoal has a surface area that reaches approximately 300 square meters (3000 square feet).
Therefore, water and air can pass easily. Furthermore, various impurities or foreign matter will be absorbed on the wide surface area of the charcoal. When air passes, and if humidity is high, the charcoal will absorb the moisture, and air will be converted to dry. If the air is too dry, then the charcoal will discharge its moisture adjusting the humidity in the air.

3. Air purification – Takesumi supposedly improves indoor air quality by absorbing harmful chemicals such as formaldehyde and benzene, among others, due to its porous nature.

4. Deodorizer – Bamboo charcoal can also absorb odors. I’ve honestly found this to be effective in our home. Put a couple small bags in the fridge and it will work better than even baking soda at keeping our fridge smelling good.

5. Keep fruits and veggies fresher longer – Put a small bag of takesumi in the crisper, they will last 2-3 days longer than without it in there.

6. Add to bath water – Takesumi makes the water more alkaline, similar to hot springs.

When you use the small bags of takesumi, you should occasionally hang them in the sun to “air out”.
