Did you know South African hunters used to chew a little plant called kanna to stay sharp and suppress hunger on long hunts? Scientists just tested kanna on mice and found it really does tweak brain chemicals linked to mood, stress, and alertness! The wild part? The plant’s effects change depending on where it’s grown. This could mean a future where natural mood boosters are tailored to you—straight from nature’s pharmacy. Who knew ancient wisdom had such a scientific twist? #Science #Kanna #BrainHealth
