Elimination of parasites present in animals

detoxification and intestine cleansing, assistance in remnants elimination of bacteria, fungi, mould, protozoa, endotoxins, insecticide and drug residues, as well as cations of heavy metals, cleansing intestines of the lingering mucus and hardened material

Food grade FSF Diatomaceous Earth is also responsible for non-toxic and environmentally safe elimination of parasites, fleas, ticks, bedbugs, lice, ants, aphids, and other pests. Diatomaceous Earth safely eliminates insects and parasites through physical (not chemical) destruction. Therefore, it is harmless and safe for people, plants, pets and farm animals. Microscopic, hard and sharp cylindrical shells of FSF destroy chitinous shells of insects and absorb water causing destruction and drying out of insects and parasites.

Just like in people, biologically active silicon strengthens muscle and vascular systems of animals, helps treat osteoporosis, decreases allergies, decreases frequency of upper respiratory tract infections, decreases constipation, improves healing of bone fractures, and additionally, in chickens, improves productivity of hens, improves quality of eggs, and physical form of farm chickens.
