Bacopa monnieri

Bacopa monnieri, also known as water hyssop, brahmi, thyme-leafed gratiola, herb of grace, and Indian pennywort, is a perennial, creeping herb native to wetland areas globally.

It is used in Ayurveda. In 2019, the US Food and Drug Administration (FDA) warned manufacturers of dietary supplement products containing Bacopa monnieri against making illegal and unproven claims that the herb can treat various diseases. There is inconclusive evidence of it improving cognitive performance and memory, and its safety and effectiveness remain uncertain.
