Solgar's Standardized · Full Potency (SFP) Herbs are developed through a unique process that integrates the ideologies of both traditional herbalism and standardized herbal technology. To ensure consistent and reliable phytonutrient levels, we isolate a controlled amount of these important active plant compounds. Then, we blend these enhanced, "standardized" compounds with all of the components that occur naturally in the whole root. The result is a potent, premium-quality standardized herbal extract with all of the synergistic and beneficial qualities found in nature.
