DE is the best thing since sliced bread. My husband and I ingest 1 tablespoon a day and it has helped our joints and has helped to lower my cholesterol. You need to have food grade only. Do a study on the internet to understand how it can be very helpful with different health issues. It works well as a colon cleanse. Once your colon is clean, your nutrients are absorbed better as well as digestion restored to proper levels. No more constipation. I don't have to use cream rinse in my hair anymore. I no longer have to use lotions either. I had a huge problem with dry cracked heels and no longer have that problem. We use the DE in our chicks nesting boxes and dusting areas. We also use it to keep bugs down in our rabbitry. We give 1/2 tsp daily to our dog that has joint problems and I think it is helping her. We no longer have to put those drops on our pets to prevent fleas and ticks. The DE helps rid them and it has no chemicals. I never will stop taking this until I die. It's that good!!!
