Olfactory training is an oki therapeutic option to promote the regeneration of the olfactory epithelium and olfactory tract. It is performed with undiluted, pure, chemical-free plant extracts and essential oils for 12 weeks, but is recommended for up to 15-18 weeks if ineffective. Dr. Magdolna Krasznai, ENT specialist at Dr. Rose Private Hospital, talks about this therapy and the importance of smell.
