Nasya is a traditional Ayurvedic therapy that involves the administration of herbal oils or powders through the nasal passages. This practice is believed to help clear the sinuses, improve respiratory health, and enhance mental clarity. It is often used to treat conditions like allergies, sinusitis, and headaches. The procedure typically includes the patient lying down with their head tilted back, allowing the practitioner to apply the herbal preparation into each nostril. Ayurveda, the ancient Indian system of medicine, emphasizes the balance of body energies, and Nasya is considered an important part of maintaining overall well-being.
