An extract of an herb that is made according to official (and unofficial) pharmaceutical practice, with a strength of 1:1. That means each ounce of the fluidextract has the solutes found in an ounce of the dried herb. Advantageous for some herbs (such as Arctium or Taraxacum), where the active constituents retain the same proportions as in the plant, even though reduced to a very small volume of menstruum, it is deadly for others (such as Hydrastis or Lobelia), whose constituents may have wildly varying solubility, and whose fluidextract will contain only the most soluble constituents and lack others completely.
