Investigating the Therapeutic Potential of Plants and Plant-Based Medicines: Relevance to Antioxidant and Neuroprotective Effects.

Oxidative stress is a common characteristic of psychiatric, neurological, and neurodegenerative disorders. Therefore, compounds that are neuroprotective and reduce oxidative stress may be of interest as novel therapeutics. Phenolic, flavonoid and anthocyanin content, ORAC and DPPH free radical scavenging, and Cu and Fe chelating capacities were examined in variations (fresh/capsule) of Queen Garnet plum (QGP, ), black pepper () clove (), elderberry (), lemon balm () and sage (), plus two blends (-lemon balm-rich, WC and R8).
