Lemon balm (Melissa officinalis) is a perennial herb primarily known for its calming effects. Its main bioactive compounds, like rosmarinic acid, are thought to increase GABA levels in the brain by inhibiting the GABA transaminase enzyme, leading to reduced anxiety and improved sleep quality. From a healthspan perspective, its value lies in mitigating the systemic, pro-aging effects of chronic stress and poor sleep.
