Materia Medica

Viriditas tinctures are made by hand in small, controlled batches using organically cultivated or ethically wild crafted herbs, some of which are grown in our own teaching garden. In addition to the singles listed in the catalogue, we also produce a number of excellent combinations and, will compound custom remedies to your specifications that meet the needs of your clients.

Our Hydrastis canadensis, Chamaelirium luteum and Cimicifuga racemosa are organically grown and not wildcrafted.

All of our tinctures are 1:5 prepared according to specifications set out in:

  • the Canadian Pharmacopoeia (CP)
  • the United States Pharmacopoeia (USP)
  • the British Pharmacopoeia (BP)
  • the King’s American Dispensary (KAD, a publication of the former Eclectic Medical Association)

Tinctures are extracted in pure reverse-osmosis water, using pure grain alcohol, with the addition of organic apple cider vinegar or vegetable glycerine as adjunct solvents when required.

Detailed information is available at your request regarding weight ratios, dosages and dispensing, botanical safety, monographs and sources of ingredients.
