Rapunzel - Here are "my" ideas about the following therapies.
1)
Light Therapy - There does seem to be noticeable improvement in those with SAD (seasonal affecive disorder), but I have seen little encouraging evidence for it's use in treating other variations of the syndrome of depression.

a)
Season Affective Disorder (SAD) - SAD is being recognized as a true sub-type of major depressive disorder (I think). If I had to guess, I'd say that "cabin fever" may have been loneliness exacerbated SAD (just thinking out loud).

2)
St. John's Wort (SJW) - this drug is recommended to those with mild to moderate depression. It should not be used in major depressive disorder, nor in bipolar disorder.
Researchers (incl. government - Health Canada, NIMH, etc.) are starting to scientifically study SJW using the good old (good, but not perfect) large-scale, randomized, double-blind clinical trial.
Mild to moderate depressions usually do not require medications (ie. antidepressants). Talk therapies, with a psychologist or a counsellor (depending upon situation and needs) are very useful in mild to moderate depression.
My psychologist; who wrote her PhD thesis on grief after loss of a child. I wish that I had met here 10 years ago. She has shown me why I do what I do, and if I wasn't such a "stodgie old proot" I'd work more these areas.
A good therapist is able to get to the core of your problem, but even the best therapist cannot "make" you better; nor can just taking an anti-depressant "fix a depression". The hardest work,
as usual is done by the person with the least amount of energy, those with depression.
Enough of my yapping. Here is NIMH's position on St.John's Wort
