The Heart-Shaped herb is a plant unique to Wakanda. It grows nowhere else and is jealously protected by Wakandan's mightiest warriors.
The herb originates from a Kheran botany ship that crashed into Wakanda millennia ago. A special ritualistic preparation is required to use the herb to full effect. For tribal leaders of Wakanda, the herb triggers a latent metagenetic event. It promotes rapid physical development and propels the user to the peak of human physical and mental capability. The use of this herb by the royal family has been key to their rule for centuries.
