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. They are completely soluble in water and so can also be used directly for instant-tea drinks.

Versatile, naturally

Our products are available in the following galenic forms :

  • Instant teas
  • Fine cuts
  • Tablets
  • Film-coated tablets

We can supply all products in bulk. Or packed in composite drums, glass jars, plastic drums or blisters according to your specification.

  • Fully-automated in-process control with continuous monitoring of process parameters
  • Microbiological purity through sterilisation with no damage to herbal actives
  • Careful isolation of the active-extracts through vacuum- and/or spray-drying
  • In-production control and analysis of active ingredient content (High Performance Liquid Chromatography)
