Contract Manufacturing – naturally, for you

roha specializes in refining high-quality extracts from medicinal plants and herbs. In doing so we place the emphasis on careful and protective processing which maintains and delivers substantive and sustainable quality and a standardized quantity of active. Our products – which, it goes without saying, are free from impurities – undergo careful water-based extraction and spray-drying.
