Olfactory training

Olfactory training is a therapeutic approach designed to improve the sense of smell, particularly after loss or impairment, such as following a viral infection. It involves regularly sniffing specific scents—often strong and distinct ones like rose, lemon, clove, and eucalyptus—over several weeks. This process helps retrain the brain's olfactory system, promoting better scent recognition and recovery. Olfactory training is simple, cost-effective, and can be practiced at home, making it accessible for those seeking to regain or enhance their sense of smell.
