Mental illnesses are affecting several millions of individuals in the
U.S and worldwide. Statistics have revealed that one among six adults in the
United States is suffering from a mental illness with varying severity. Accordingly,
mental illnesses are considered as one of the major factors behind
the global disability as well as health and economic burden. The conventional
treatments prescribed to treat mood and mental disorders are observed to
show a response in only 30-40% of patients with major depression disorder
(MDD). Besides, the serious adverse events associated with these treatments
have also made it urgent for scientists and researchers to search for other alternatives
to be used as monotherapies or adjuvants to conventional treatments. In this
review, we have summarized a number of the most extensively-studied natural remedies indicated
for the treatment of anxiety and depression. We have also included some of the common
nutraceuticals used to treat both anxiety and depression, along with a number of the
newly-emerged adjuvant therapies.
