Assure your product claims are backed by science

Analysis of the efficacy of a botanical product includes examination of the following information:
  • Human clinical trials - what do human studies tell us about the benefits of the product or ingredient?
  • Pharmacological studies (in vitro, biochemical and/or animal studies) - what is known about the possible mechanism of action and possible active chemical constituents?
  • Pharmacopoeial listings - which Pharmacopoeias have profiled the herb in question and what are their recommendations?
  • Traditional Use (ethnobotanical data) - how has this herb been used in traditionally, by which cultures and in what context?
Analysis of the safety of a botanical product may include an assessment of:
  • Reports in medical literature - descriptions of adverse events in clinical trials, post marketing surveys and case reports
  • Pharmacological profiles - animal safety studies and in vitro toxicological studies
  • Drug/Herb interactions - evaluation the probability of interaction(s) with drugs or other herbs. Is the evidence based upon a single report, a theoretical mechanism of action, or a clinical study?
  • History of use - what clues can the history of use tell us about safety?
  • Identity of the herb - Some herbs, although safe themselves, can be substituted with others that may pose a safety hazard.
  • Product quality - Be aware of its role as it relates to the safety of your products.
