Holistic Herbal Medicine

Tailored to your individual needs

What is
Clinical Herbalism?

At Root Cause Herbals, we take a holistic health care approach, focusing on treating the person as a whole: body, mind, and spirit. Through detailed health assessments and 1:1 consultations, we create individualised care programs, including custom herbal medicine, nutritional guidance, and mineral rebalancing.

Rather than addressing symptoms in isolation, we work towards identifying the root cause and underlying patterns of imbalance, rebuilding strong foundations to support the body’s overall well-being and vitality.

    Thanks to Fieke, my body is getting stronger everyday. My immune system is finally working again and together we’re building strong basis of healthy routine in my everyday life not only by providing me with herbal tinctures, tea and steaming but also by giving me some food tips to receive enough protein and vitamins throughout the day. Every little detail is important to her, she’s trying to find the source of your problems, taking your life situation and your mental state in account. Plus, Fieke is the kindest person on earth. It's a pleasure to work with her.

    I am incredibly pleased with the care my teenage daughter has received from Fieke. She takes the time to listen attentively and seeks to understand the underlying causes of health issues. The online appointments have been invaluable for my daughter, who now sees her as a trusted confidante. We have already noticed a remarkable improvement in her skin, and the recovery is steadily progressing. We are very grateful for the support and dedication she provides. It’s heartwarming to see how positive this experience has been for my daughter.

    I reached out to Fieke after a big surgery, months of painkillers and years of bad digestion. My main goal was to reduce the amount of drugs I was ingesting. Fieke helped me set some health goals that we are working on together. I love how she works on an overall view of my health instead of placing the focus only on one specific thing. Thanks to her, I realized that one of my problems can actually be linked to other problems. In just a few months we were able to reduce painkillers, I found out I can reduce and sometimes get rid of the pain caused by a chronic sinus infection, and I learned to listen more to my body's needs. She’s literally teaching me how to take care of my body. All this has been having a positive result on my mood and lifestyle.

    Working with Fieke has been an absolute joy! She has an incredible ability to truly understand all the factors in my life that may be influencing my hormones and overall well-being. Her holistic approach is nothing short of transformative. ... Each formula is thoughtfully tailored to match the unique changes in my body each month, ensuring deep, personalised healing. Since starting with Fieke, my central nervous system has felt more balanced, and my energy levels have improved significantly. What sets Fieke apart is her dedication to going above and beyond. She provides thoughtful nutrition and lifestyle recommendations that complement her treatments and support your overall wellness journey.
