Scientific Summary
Griffonia simplicifolia is a small flowering shrub from tropical Africa whose root contains high levels of 5‑hydroxytryptophan (5‑HTP). It is mainly used as a natural supplement to improve mood, reduce anxiety, and promote sleep by boosting serotonin production. People taking antidepressants, MAO inhibitors, or who are pregnant or breastfeeding should use it cautiously, as it can lead to serotonin syndrome or other interactions.
