My silicea is actually, I found after remembering the product I used, diatomaceous earth. It strengthens connective tissue( skin, ligaments, tendons) and helps grow healthy skin, hair and hooves. Strengthening the connective tissue I saw. Big time. Like I said, Hafi lost the spongy, flabby appearance.
