She has said endometriosis, infertility, miscarriage, and sexually transmitted infections (STIs) are caused by spirit spouses, and has also endorsed a number of conspiracy theories that include the involvement of space aliens and the Illuminati in manipulating society and government.
[4][8][9] According to Concordia University theological studies professor André Gagné, Immanuel's beliefs originate in African Pentecostalism and the charismatic movement.
[11] In April 2020, local deputies were unable to serve notice of the Louisiana suit because Immanuel had moved to Houston, where she set up a new practice.
[1] Immanuel's medical claims are sometimes combined with her spiritual beliefs: she believes many gynecological illnesses are the result of having sex dreams with succubi and incubi, and receiving demon sperm; and that endometriosis, infertility, miscarriage, and sexually transmitted infections are caused by spirit spouses.
[5][2] In a 2015 sermon, Immanuel said space alien DNA is used in medical treatments and that "reptilian spirits" and other extraterrestrials run the U.S.

[5][2] On July 27, 2020, Immanuel appeared in a Tea Party Patriots-backed press event that was organized by the group "America's Frontline Doctors"[a] in front of the steps of the U.S. Supreme Court Building.
[13] She said she had cured COVID-19 in 350 patients at her clinic using a combination of hydroxychloroquine, azithromycin, and zinc,[b] and that public health measures such as the wearing of facial coverings and social distancing are unnecessary.
[17] On October 15, 2021, the Texas medical board took corrective action against Immanuel over her hydroxychloroquine prescription for COVID patient.
In the decision, the board ordered Immanuel to submit proof of informed consent, or permission given by a patient who understands the possible health outcomes, for all of the off-label treatments she provides.
[26] In March 2023, MedPage Today reported that Immanuel was the single highest prescriber of Ivermectin and Hydroxychloroquine in the United States for the years 2021 and 2022.
