St. John’s Wort lost its popularity in the 1800’s but has made a rebound in recent years. It is the number one treatment for depression in Germany and at one point it had outsold the antidepressant Prozac.

In the mid-1600’s it was popular to use earthworms and other animal parts as a medicinal ingredient. An oil compound made up of St. John’s Wort, earthworms, and other herbs were a popular remedy at that time.

In Christain tradition, oil infused with St. John’s Wort was often called the blood of Christ and was used in healing and during religious ceremonies.

St. John’s Wort has been hung above doorways, on bedposts, and worn to banish evil spirits and drive away storms and anything that could cause harm. It was also included, along with other herbs, in amulets, charms, and talismans.

Studies have been done on how well St. John’s Wort treats depression. Some studies found that it worked better than prescribed antidepressants, some found that it didn’t work any better than a placebo, and some studies found that neither the herb or the medications helped. More studies are needed and there is no consistent evidence on how well St. John’s Wort works for treating depression.
