Hubner silicea gastrointestinal gel 200 ml is best for the treatment of gastrointestinal illnesses causing, stomach aches, nausea, vomiting, flatulence, heartburn & diarrhoea. The active ingredient of silicea gel for the gastrointestinal system is silica gel (silicic acid gel) a compound made up of the mineral silicon with oxygen & water. What makes silica gel so special is that it has an unusally high bonding capacity for pathogens & their toxins. This means that pathogens & their toxins are bound by a purely physical process in the gastrointestinal tract & excreted naturally by the intestine. Silicea gel for the gastrointestinal system soothes your symptoms & supports the regeneration of your upset gastrointestinal tract. Because silica gel binds gases in addition to binding pathogens, it can also reduce annoying flatulence.
