Holistic health practitioners and herbalists of all kinds are protected by their right to free speech from the First Amendment of the United States Constitution.
Such individuals are free to educate clients on how to use health foods, meditation practices, and lifestyle changes, including the use of herbal remedies and natural protocols for their mental, emotional, physical, and spiritual wellbeing.
Of course, obviously it is illegal for holistic medicine practitioners to practice conventional medicine, which includes to treat disease, diagnose medical conditions, prescribe pharmaceutical drugs or claim to ‘cure’.
Of course there’s always the occasional crazy person who studies natural medicine and pretends to be a medical doctor, but that’s one of the reasons we screen all applicants to our school.
If you reside in the United States, and most other countries, you can practice holistic medicine like iridology, herbalism, and traditional naturopathy without a license or certification, and you can legally charge for your services as a holistic practitioner in any speciality, whether that’s iridology, herbalism, spiritual medicine, etc. You are not required to ‘go to school’ first —but it sure helps!
