Gotu kola (Centella asiatica) has a long traditional use for the mind in Ayurvedic and Southeast Asian medicine. It contains compounds called triterpenes studied for effects on mood and cognition.
Per Memorial Sloan Kettering’s herb database, human evidence for gotu kola improving cognition is preliminary and not strong enough to be conclusive. It is the herb in MemoFlow most linked to the mind, and we present its evidence honestly rather than overstating it.
Rare reports of liver effects exist. People with liver conditions or on medications should consult a doctor.
