The reason that bipolar disorder is so complicated is that it can appear in so many different forms. From mood swings to lethargy and loss of interest in regular activities, bipolar disorder can be hard to diagnose and treat. Ginseng, however, has been a trusted remedy for lethargy and depression for generations. This ancient Chinese remedy can be consumed daily to boost energy levels and lower anxiety, two issues that are commonly associated with bipolar disorder. Ginseng supplements are readily available, and ginseng tea is another popular method of consumption.
