Alfredo Darrington Bowman (26 November 1933 – 6 August 2016), better known as Dr.
Sebi, () was a Honduran herbalist and self-proclaimed healer.
Bowman claimed to cure all disease with herbs and a vegan diet based on various pseudoscience claims.
His diet was based on the discredited alkaline diet.
His beliefs on the origin of disease denied germ theory and taught that HIV is not the cause of AIDS, and factored in faux-afrocentric claims about the unique genetic characteristics of Africans and their diaspora.Although he used the name Dr.
Sebi, Bowman was not a doctor and was considered a quack by actual doctors, attorneys, and consumer protection agencies.
