The Heart-Shaped Herb is a special Wakandan herb.

Its juices help enhance the senses of the kings of the Panther Tribe and is applied to the skin. It is also a lethal poison to those not of the royal line, which T'Challa told Hawkeye after he tasted it.[1]

The Heart-Shaped Herb tree was located above the Wakandan embassy in Manhattan, New York.
