Benefits of St. John’s Wort in Depression Treatment

There are dozens of unofficial sources claiming that St. John’s Wort can be used to treat mild depression and might even help with more severe cases of depression – lowering down symptoms through which it manifests.

  • In 2008, roughly about 30 international studies did show that St. John’s Wort is better than a placebo in treating depression and was put in the rank of standard prescription antidepressants.
  • It also appeared that St John’s Wort has fewer side effects than standard synthetic drugs for treating depressive people.
  • While having success in some studies, back in 2002, a study funded by NCCIH concluded that St. John’s Wort had no better results than a placebo in treating depression.

How it Actually Works?

St. John’s wort is a reuptake inhibitor of a substance named serotonin (shortly SSRI), serotonin is a chemical in the brain linked to depression and anxiety. Serotonin plays an important role in mood regulation and happiness. The thing is, everyone can feel down or unhappy for some time. But in people with depression, this becomes so severe that it interferes with their daily life.

In general, SSRIs are considered to be fairly safe for treatment. They enhance the function of nerve cells in the brain. More specifically, when information is transmitted between brain neurons, it is achieved with signals named neurotransmitters. They communicate in between with some protocol and need to take back the information already released in order to send new information. The process of replacing neurotransmitters is named “reuptake”.
