Overall there was a significant change in participants depression levels, life satisfaction levels, mindfulness levels, and anxiety/stress levels. Depression and anxiety/stress levels decreased, while mindfulness levels and life satisfaction levels increased.

Results of Ayahuasca Use in Clinically Depressed Patients

A study was conducted to test the effectiveness of ayahuasca as a possible treatment for depression. Participants of this study were categorized as having mild to severe depression, a score of 13 or greater on the Beck Depression Inventory (BDI) and symptoms of chronic depression for at least 2 years. Participants were given ayahuasca once and took questionnaires to asses their symptom levels before using ayahuasca, one week after use, one month after, and one year after using ayahuasca.

A brewed Amazonian drink with psychoactive properties made by boiling Banisteriopsis caapi vine and Psychotria viridis bush leaves ( which contains harmala alkaloids, which render the hallucinogenic component DMT orally active).  It was originally used by indigenous shamans for religious rituals and healing. Now it is being used for recreation, being incorporated into folk medicine, and treatment for addiction, anxiety, and depression.

The vine containsc (MAOIs) such as beta-carboline harmala alkaloids; alkaloids harmine, tetrahydroharmine (THH), and small amounts of harmaline. 

Banisteriopsis caapi vine Chemical Makeup

The bush leaves contain the psychedelic N,N-dimethyltryptamine (DMT).

Psychotria viridis Chemical Makeup

Ayahuasca has been shown to interfere with   DMN function after the administration of the drug. Furthermore, long-term ayahuasca use has led to the increased thickness of the ACC and decreased thickness of the PCC which are key components of DMN.  Studies also show an increase in local network integration as well as a decrease in global network integration.  This also occurs as there is an increase in Shannon entropy across networks.
