DEET works, but specific essential oils have been shown to be as good or better than DEET at repelling ticks.

Aromatherapy anti biotic treatment:

ALL essential oils are anti-biotic, and there are dozens of essential oils that are potentially effective against Lyme bacteria. Some of these essential oils are clove, eucalyptus, cinnamon, cypress, rosemary oil, hyssop, mountain savoury, frankincense, oregano, thyme, tea tree, plus immune-boosting oils. Rose geranium not only repels ticks, but as an antibiotic, it is notable for NOT disrupting the healthy bacteria of our intestines.

I have NO experience treating Lyme Disease, but I am willing to share what I understand, and to prepare essential oils, herbal remedies and blends for a client who is devising a protocol with their primary care practitioner. You can receive natural and effective remedies without resorting to a one-size-fits-all multi-level marketing package. Where I cannot provide what you need, I will do my best to refer you to an apothecary that can.

And a brief reminder about how to prevent Lyme Disease:
Repel ticks using clothing, DEET or essential oils.
Reveal ticks by wearing light-coloured clothing and inspecting your body regularly.
Respond immediately to ticks you find on you by safely removing them. See a medical practitioner right away if you develop a bull's eye rash, and get treated.

Have a safe, happy spring, summer and fall out of doors.
