Although hugely popular, Withania somnifera is often contaminated with related species Withania coagulans. Withania coagulans is also important plant for its property of coagulating milk. To ensure the best male sexual health benefits HeezOn® uses only DNA authenticated roots of Withania somnifera. DNA finger printing of Withania somnifera roots.
Out of several species of Alpinia, three most commonly grown species are Alpinia galanga, Alpinia calcarata and Alpinia officinarum. The roots of Alpinia galanga and Alpinia officinarum are well identified in trade as greater and lesser galangal respectively. But the roots of Alpinia galanga and Alpinia calcarata appear very similar to the untrained eye and hence any adulteration or substitution can go unnoticed. Because of the close similarities between Alpinia calcarata and Alpinia galanga, a macroscopy, microscopy and DNA testing together helped authenticate EnXtra® raw material.
