Takesumi's 1 binchotan charcoal stick - Laos (2cmx11cm) balances the pH of water and adsorbs toxic molecules and residues still present in running water. The taste of the water is improved and its quality is optimized. The water purified with Binchotan can be consumed by expectant mothers and babies. Combustion of wood at low temperature then at high temperature +/- 1000 ° C for natural activation. Cooling in a mixture of ash and sand, which gives it its whitish surface. (Japanese ancestral method) The activation of the wood will allow it to free its pores of any material, thus, it becomes extremely porous and can attract and retain toxic particles to it. It is recommended to boil the stick for 10 to 15 minutes. Immerse 1 stick / liter of running water in a container (carafe, gourd ...). Leave to act between 4h and 10h and consume. The stick can stay in the water for 1-3 months. Beyond that, boil it again for 10 minutes to purify it before reuse. (empty its pores of toxic particles accumulated during its immersion in water). As soon as the taste of the water changes, remove the stick to boil it. Lifespan: 3 to 6 months depending on the quality of the water. Recycle as plant fertilizer
