Agnihotra was already described in ancient scriptures as an Ayurvedic smoking ceremony. During this cleansing fire, ghee, cow dung and brown rice are burned while mantras are recited. The ritual is traditionally performed at sunrise and sunset. Ayurvedic medicine uses smoking as an additional treatment method for respiratory diseases, headaches or mental illnesses. Smoked goods are also used as fragrances and cleaning agents for the air in the patient's room, as they create a good atmosphere and have a disinfectant effect.
