Before 3000 BCE: (The Tamarind and the Castor-Oil Plant — Two More African Gifts to the World, the Tamarind as a West African Fruit Tree That Became Particularly Important in India and Spread to Island Southeast Asia, and the Castor-Oil Plant Originating in the Horn of Africa Having Already Reached Egypt by the Third Millennium BCE Before Achieving an Almost Worldwide Distribution): The West African contributions to what Ehret calls the Age of Agricultural Exchange included a fruit tree species that most people today associate with India: the tamarind. Yet the tamarind is African in origin, a West African tree that took on particularly notable importance in Indian cuisine, medicine, and culture, and from there spread further to Island Southeast Asia. Add to this the castor-oil plant, which originated in the Horn of Africa and had already spread by the third millennium BCE, if not earlier, to Egypt, before eventually achieving an almost worldwide distribution. The castor-oil plant’s global reach is so complete that its African origins have vanished from common knowledge entirely — it belongs to that category of African contributions so thoroughly absorbed by other civilizations that the source has been rendered invisible. This is the pattern that recurs throughout Ehret’s account in Ancient Africa: A Global History — African innovation radiating outward, being adopted, being transformed, being claimed, and being forgotten. The tamarind that flavors your pad thai. The castor oil in your medicine cabinet. These are African products, and the fact that saying so still surprises people is itself an indictment of how history has been taught.
