Hello! Do you know any marketed and standardised or registered product derived from plants and used as anti-diarrhoeal or anti-infective in the gastrointestinal diseases in ruminants? Like for e.g. allicin, berberine, or may be purified fractions of some extracts, essential oils, oleoresins, etc., but it must be really standardised or registered in the EU, USA, Canada, Japan or somewhere and it must NOT be polyherbal formulation. Please help me if you know any such products. Thank you,
