Karnapoorana is an Ayurvedic therapy that involves the application of medicated oils or herbal liquids into the ear to promote health and address various ear-related issues. The term "Karna" means ear, and "Poorana" means to fill or pour. This therapy is primarily used to treat ear conditions such as earaches, hearing problems, tinnitus (ringing in the ears), ear infections, and even to promote general ear health and well-being.

The treatment typically involves warming herbal oils or medicated liquids, which are gently poured into the ear canal. The oils may be left in the ear for a few minutes, allowing them to soak in and provide therapeutic benefits. The process helps to lubricate the ear canal, reduce inflammation, and promote healing. It is also beneficial for balancing the doshas (energies) in the body, particularly Vata dosha, which governs the nervous system and hearing functions.
