Wood ash can be used to absorb humidity and help prevent moist areas from developing mould. Place a cup of wood ashes in a damp cupboard or basement room. Again, small chunks of charcoal left in the ashes help for this purpose.
Wood Ash Toothpaste
Some varieties of wood create an ash that serves as a natural whitener in homemade toothpaste. The toothpaste, well actually, most recipes that use wood ash to whiten teeth are technically a tooth powder, typically has a very pleasant taste. Ash from some trees are not suitable for homemade tooth powder, conifer trees, in particular, are far too astringent and can actually damage tooth enamel.
The potassium hydroxide (lye) present in wood ash can help get rid of plaque while whitening teeth. Daily use of wood ash for an extended period of time has caused tooth enamel damage, regardless of the type of tree that was used as firewood, in some individuals.
The ash from soft wood is most often used when creating this type of homemade tooth powder. To make a wood ash tooth powder, simply combines equal parts of the ash with any one or more of the following: baking soda, orange peels, lemon peels, turmeric, cinnamon, anise, cloves, activated charcoal, bentonite clay, xylitol, and calcium carbonate.
Pour the ingredients into the blender and hit pulse for about 30 seconds. Dip a dampened toothbrush into the powder and brush your teeth as you would with commercially manufactured toothpaste.
