  1. Diatomaceous Earth – FOOD GRADE – Is great. I use it in my chicken coop to kill off mites, safe for chickens and humans to eat. I have a friend that eats it, she claims it lessons the severity of her arithritis. I also use it mixed with sand, peat moss in the chickens dust bath I made them !! 🙂

  2. I have been reading about the consumption of diatomaceous earth. I live in Singapore with 5 kids and have suffered from Sjögren's syndrome since 2010. I am currently suffering from extreme hair loss, fatigue, and extreme eye dryness with numbness at limbs at night.Will be very happy to hear more testamonials of consuming DE before l plunge into this journey. Eating earth is totally unheard of in Singapore.

  3. I love and swear by food grade DE, it does so many amazing things! My vacuum however despises it…the thin powder goes to town on the filter and takes a big toll. Something to keep in mind before the carpet treatments!

  4. Does anyone know if spreading D-Earth all over a carpet with potential mold/mycotoxins in it would be effective in killing the mold?
