Is bacopa the same as brahmi?
Not reliably. “Brahmi” is used for both Bacopa monnieri and gotu kola (Centella asiatica), and market products often do not match their label.

The short answer
In Ayurvedic and commercial usage the name brahmi is applied to Bacopa monnieri and also to Centella asiatica, an unrelated plant in the carrot family. A DNA metabarcoding study of Brahmi products found only a fraction contained the species on the label. The two plants have different chemistry, traditions and safety records, so look for the full scientific name Bacopa monnieri on any product before applying bacopa research to it.
