NAET (Nambudripad’s Allergy Elimination Techniques) is an alternative therapy that combines applied kinesiology and acupressure to identify and desensitize the body to perceived allergens or sensitivities. During a session, specific substances are tested while gentle stimulation is applied along acupuncture meridians to support the body’s adaptive response. The goal is to reduce reactivity and improve tolerance to environmental, food, or chemical triggers. NAET is often used as part of a broader integrative approach to support immune balance and overall wellness.

An Ayurvedic consultation is a holistic health assessment that evaluates an individual’s constitution (dosha), lifestyle, and areas of imbalance to guide personalized care. It incorporates a detailed review of digestion, sleep, stress, and daily habits to understand root contributors to health concerns. Based on this assessment, tailored recommendations are provided for diet, herbal support, and lifestyle practices aligned with Ayurvedic principles. The goal is to restore balance, enhance vitality, and support long-term well-being through sustainable, individualized care.
