Abstract
The inventors have devised novel approaches for the preparation of flavanolignan compositions of enhanced solubility and substantially free of toxic contaminants. Such novel approaches are based on spray drying or lyophilizing to dry a diluted preparation of flavanolignan. These approaches avoid the use of toxic excipients and or carriers commonly used to precipitate flavanolignan concentrates and thus address the drawbacks of existing methods and compositions.
