Lemon:
This evening, after watching part of a documentary involving the use of bee venom for Lyme disease, I checked Oil Testimonials to see if anyone had had any success with EOs in Lyme disease. The search pattern I used was "lyme site:oil-testimonials.com". Sure enough, people have had (anecdotal) success with multiple different mixtures of oils, after terrible experiences with regular medical approaches. No guarantees, but perhaps worth more research.
The documentary that inspired this search was part of the new Netflix series (Un)Well, a somewhat balanced look at various alternative wellness methods, including EOs, tantra, ayahuasca, and bee venom. They present the successes that many people have achieved with such methods as well as some of the risks and unethical behavior that exist in the alternative medicine world.
