Dhanadanayanadi Kashayam is a classical Ayurvedic formulation traditionally used in disorders affecting the eyes, head, and facial nerves, with specific reference to Netra Roga (eye disorders) and Ardita (facial paralysis). It contains herbs like Dhanadaphala, Shunti, Shigru, Rasna etc which help nourish the nervous tissue, reduce Vata-induced dryness and weakness. The formulation is particularly useful in eye fatigue, and in Ayurvedic protocols for facial palsy and neurological rehabilitation.
