Griffonia Simplicifolia

OTHER NAME(S): Griffonia simplicifolia, Bandeiraea simplicifolia, Schotia simplicifolia

Overview

Griffonia simplicifolia is a shrub native to West Africa. Its seeds contain a chemical called 5-hydroxytryptophan (5-HTP) and are used as medicine.

5-HTP works in the brain and central nervous system by increasing the production of the chemical serotonin. Serotonin can affect sleep, appetite, pain, and mood.

People use Griffonia simplicifolia seeds for anxiety, depression, headache, insomnia, motion sickness, stress, obesity, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse Griffonia simplicifolia with 5-HTP, the main chemical in Griffonia simplicifolia seeds. These are not the same.
