Restoring digestive balance can help to reduce allergic response. Dr. Bowen helps with identification and removal of allergic triggers, assisting the body to produce less pro-inflammatory products.

We believe that when skin conditions arise, they serve as indicators of underlying imbalances within the body. Our primary focus is on restoring balance to the digestive system, as we recognize its crucial role in addressing skin concerns. By delving into the root causes of these conditions, we can develop tailored treatment plans encompassing nutrition, lifestyle adjustments, and psychosomatic approaches. Our goal is to not only alleviate the current condition but also to prevent future issues from emerging. Recognizing that the skin acts as an organ for elimination and detoxification, we take a comprehensive approach by facilitating detoxification through various methods. This holistic approach allows us to effectively address skin conditions like psoriasis, eczema, acne, chronic hives (urticaria), rashes, and more, providing sustainable solutions for our patients.
