Who is Barbara O'Neill?
Barbara O'Neill is an Australian health educator, author and speaker who has spent over five decades teaching natural therapies and wellness. Her approach focuses on natural healing, prevention and the body's ability to heal itself when it's given the right conditions.
Through her seminars, workshops and best-selling books, she has introduced millions of people to simple remedies such as Celtic salt, castor oil packs and herbal teas. Barbara is not a medical doctor, and she presents her teaching as health education rather than medical treatment.
Her philosophy comes down to four ideas:
- Natural healing first: use whole foods, herbs and simple remedies.
- Prevention and lifestyle: diet, water, sunlight, rest and movement do the heavy lifting.
- Balance: address stress and burnout, not just symptoms.
- The body can heal itself: remove obstacles and give it what it needs.

- May help relieve discomfort during menstrual and menopausal stages
4. Activated charcoal
Barbara recommends activated charcoal for its ability to bind substances in the gut.

Barbara recognises the importance of collagen for skin, joints and the gut lining.

- Traditionally used to support sinus and respiratory health
