Alfredo Bowman

Rapper Kendrick Lamar references "Dr. Sebi" by name in the lyrics to the song "Worldwide Steppers" from his 2022 album Mr. Morale & the Big Steppers.

In 2018, African-American rapper Nipsey Hussle stated he was planning on creating a documentary about Bowman's successful defenses at his criminal trials. Hussle was later murdered in 2019 by an acquaintance. Law enforcement have found no link between Hussle's death and Bowman.

In May 2016, Bowman was arrested in Honduras for money laundering, after being found carrying tens of thousands of dollars in cash with insufficient accounting for its origin. During several weeks' detention in jail, he contracted pneumonia. He died in police custody as he was being transported to a hospital.

On 28 May 2016, Bowman and his associate Pablo Medina Gamboa were arrested on charges of money laundering at the Juan Manuel Gálvez de Roatan Airport, after they were found to be carrying $37,000 in cash and had no explanation for it. They were attempting to transfer from a commercial flight from the United States to a private plane for another destination in Honduras.

Bowman was released pending a court hearing on 6 June 2016, but he was re-arrested by the Public Ministerio on money laundering charges. He was held for several weeks in a Honduran prison, while his family was attempting to obtain his release. He fell ill and, after police officials realized the severity of his condition, they transported him to a hospital. Bowman died of complications of pneumonia on 6 August 2016, en route to Hospital D'Antoni. The length of his time in custody and the poor condition of the jail may have contributed to his death.

After Jackson's brother Randy paid Bowman $10,000, Bowman sued Michael Jackson for related costs, claiming that the singer owed him $380,000, and seeking an additional $600,000 in lost revenue for having deferred other clients and various speaking engagements. Raymone Bain, a publicist of Jackson, denied that her client received any "professional treatment" or that he had any painkiller addiction. The case was dismissed in 2015 for lack of prosecution.

He gradually earned considerable revenue, more than $3,000 a day, after giving advice and developing a wide range of celebrity clients such as Lisa Lopes, Steven Seagal, John Travolta, Eddie Murphy and Michael Jackson. He reportedly treated Jackson in 2004, before the latter went to trial.

In 2004, Bowman reportedly treated Michael Jackson prior to his being tried on counts of child abuse. Bowman claimed to have helped the singer overcome addiction to painkillers Demerol and morphine with his African Bio-Electric Cell Food Therapy. He worked with Jackson for six months at a retreat in Aspen, Colorado.

In 1987, Bowman was arrested and charged in New York with practicing medicine without a license. The jury acquitted him, saying the state had failed to prove he made a medical diagnosis. In the 1990s, he was sued in New York for making claims of therapeutic benefits for his products; as a result of the civil case, he was prohibited from making such claims. He relocated to Los Angeles, where he cultivated celebrities among his clients.

In 1987, the New York State Attorney General charged Bowman with two counts of practicing medicine without a license after he placed ads in local newspapers claiming to be able to cure AIDS. The Attorney General's Office sent undercover agents to his office to gain diagnoses and treatments for purported symptoms of disease. Bowman was acquitted because jurors said the tape recorded by the agents failed to show that Bowman had made a medical diagnosis of their purported conditions.

Bowman set up a center in the 1980s near La Ceiba, Honduras, and marketed his herbal products in the United States. He called his center the USHA Research Institute, as located in the village of Usha.

In the early 1980s, AIDS had newly been recognized as a disease as an epidemic started in the United States, with numerous cases in New York and other major cities. Bowman claimed that HIV is not the cause of AIDS and used herbal remedies to treat people.

Alfredo Darrington Bowman (26 November 1933 – 6 August 2016), better known as Dr. Sebi (/seɪbiː/), was a Honduran self-proclaimed herbalist healer, who also practiced in the United States in the late 20th and early 21st centuries. Bowman claimed to cure all disease with herbs and a plant-based alkaline diet based on various pseudoscientific claims, and denied that HIV caused AIDS. He set up a treatment center in Honduras, then moved his practice to New York City and Los Angeles. Numerous entertainment and acting celebrities were among his clients, including Michael Jackson, Lisa 'Left Eye' Lopes, and John Travolta.

Bowman was born in 1933 in Ilanga, Honduras. He first learned of herbal healing and related traditional practices from his grandmother; his grandfather was originally from Haiti. Bowman who was a Honduran of African descent, identified himself as an "African in Honduras", not as an Afro-Honduran.
