The herbal ingredients are from organic, wild crafted (non-threatened species) or cultivated plants and conform to accepted scientific standards, British Pharmacopoeia, European Pharmacopoeia and British Herbal Pharmacopoeia.

Agnus castus, also known as Vitex or Chaste berry, contains several different constituents, including flavonoids, iridoid glycosides, and terpenoids. The whole fruit extract, rather than one of its individual constituents, appears to be necessary for the activity of agnus castus.
